According to Polish Family and Guardianship Code, while determining the amount of child support, the court takes into account the child's justified needs as well as earning and financial capacity of the person obligated to pay. To put it simply, when the judge decides about the monthly amount to be paid, all that matters is how much a parent earns (or how much they could earn if they had the best job possible considering their qualifications and skills) and the real needs of a child.
If an obligated parent is unemployed, it won't be assumed that they earn nothing and therefore don't have to pay at all. Most likely, the judge will check adequate job offers and assume that the parent could earn the amount proposed as a salary. If - in the course of the last 3 years - a parent obligated to pay child support has quit a well-paid job and/or given up their property rights (e.g. sold their house, car or land), therefore worsening their overall financial situation, the judge will not take into account such a change while calculating the amount of child support. This is meant to prevent parents sued for child support from quitting their jobs or transferring their properties to another person in order to make them seem poorer than they really are.
It is worth noting that a child has the right to the same standard of living as their parents. This means that there is no fixed amount of child support deemed adequate for e.g. a five-year-old as some children live in wealthy households and some don't. Depending on the standard of living of the child's parents, the child support could amount to both PLN 500 and PLN 2000 or more for the same-aged children.
A common misconception is that the amount needed to cover all the child's expenses should automatically be split in half because parents should pay for their child's expenses equally. In most cases the parent who does not live with the child will have to pay for more than half of the child's upkeep, as the other parent fulfills their financial obligations towards the child not only by paying for things, but also through providing daily care (we can call it 'contribution in kind' which has to be considered).
Child support claims are subject to a 3-year period of prescription (limitation), meaning that the parent sued by a child (represented by the other parent), will not have to pay child support for the time longer than 3 years before the date of the filing of the petition with the court. As a rule of thumb, the court adjudicates child support from the date of the filing of the petition (or from the date of the final judgement). If, however, the parent representing a child proves that there have been unmet needs of a child and they go back 3 years from the date of filing the petition (but not earlier than that), the court may order retroactive child support (that is rare, though).
A petition for child support should be filed with the district court (=sąd rejonowy) according to the child's place of residence. This means that if you live in the north of Poland and your child lives in the south, the court proceedings will take place in the court closest to where your child lives, i.e. in the south of Poland. It has to be drawn up and filed in two identical copies and the child's birth certificate has to be enclosed. In the petition it is important to provide the current address of the parent obligated to pay child support (it matters where they actually reside and not where they are officially registered as residing) and the child's personal identification number (PESEL). The petion can be written and filed by a child's parent, there is no obligation to hire a lawyer to do that.
As for the technicalities - the petitioner is the child represented by one of their parent, therefore during the court proceedings it will be the child versus the other parent. It is also a good idea to enclose documents such as invoices or receipts, which confirm the child's expenses, although more and more judges reject receipts as they don't prove that the given items were bought for a specific child.
If there are witnesses who could testify and are knowledgeable about the relevant issues (such as the needs of a child, financial situation of both parents) it's also advisable to give their names and addresses in the petition and ask the court to summon them as witnesses.
When you happen to be the parent who receives from the court a letter called 'petition for alimony', you'll be requested to submit your written reponse within 14 days. In your letter you should state whether you agree to pay the amount indicated by the petitioner and if not, what are your reasons. If you have other financial obligations you should enclose copies of documents confirming them (also documents stating how much your earn) and give names and addresses of your wittnesses, if any.
According to Polish law, when a child is born to a married couple, the parents share parental authority (parental rights and obligations). The same situation happens when a child is born to an unmarried couple and the father has officially recognised the child (= both parents have the same parental authority/responsibility).
However, problems arise when the child's parents split, one of them moves out of the shared home and the other still lives with the child. In such situations it is possible for the parents to continue sharing their parental authority as if nothing has changed (as long as they are on good terms), but most often, because of the existing conflict, it is not a viable option. The most common scenario is the mother filing a petition with the court for the limitation of the father's parental authority. If the court decides that it is the best solution for the child, the mother will retain full parental authority, while the father will have his limited. When that happens, the father will still have a say in his child's most important matters such as education, medical treatment, going abroad etc., but the mother will be the 'leading' parent who single-handedly makes minor, everyday decisions concerning the child. Even though the father's parental authority has been limited, the child's mother is not allowed to make crucial decisions about the child without the father's consent. If, however, they disagree about e.g. changing school or undergoing a surgery, each of the parents may petition the court and ask the judge to decide what's best for the child - the court's decision will be binding for both parents. The same applies to a parent who retained full parental authority but needs the consent of the other parent (e.g. the mother wants to move to another city and the father disagrees), in such a case the leading parent may too petition the court to resolve this issue. In the past it was almost a given that the father living apart would have his parental authority limited, in the recent years, however, the provisions have changed and judges decide that both parents should have the same scope of parental authority unless there are some extraordinary circumstances. This, however, requires good co-parenting and being able to work out any problems concerning the child amicably.
One last note - if the child's parents were never married and they both share parental authority (and want to continue doing so), it's a good idea to file a petition for establishing the child's place of residence (without it, both parents have the right to claim that their home is the child's place of residence, which may complicate a lot of things). According to Polish law a person may only have one permanent place of residence. On filing such a petition the judge will establish that e.g. the child's place of residence is that of their mother's (and then the mother's address will be indicated in all legal documents concerning the child).
Let's imagine a typical post-split situation: a couple (married or umarried) has kids, the father moves out but he doesn't want to lose touch with his children. He would like to be able to see the kids as often as possible, but the mother is reluctant. What can he do about it?
Any (honest) lawyer would say: it's best to work it out between the children's parents - if it's possible, they won't need any court decision and just play it by ear focusing on what's best for the kids. However, most break-ups are not amicable and oftentimes one way to deal with the resenment towards the other person is by limiting their contact with the children or even trying to remove that person from the their lives. If that is the case, the parent who doesn't live with the children should act swiftly as losing touch with the kids will mean hard work when re-establishing earlier connection, trust and feelings. In some cases, after a long break in contact, it may turn out to be impossible to go back to that place where you and your children left off.
Let's consider two types of situations here: 1. the parents are still (unhappily) married and one parent already limits the other parent's contact with the kids - you can either file for divorce and demand that the court grant you the right to see your children on given days or, if there are no plans for permanent solutions like divorce or separation (but the parents don't live together any more), you can file a petition to establish visitation rights. 2. the parents were never married, but have split up - you can file a petition for visitation rights as soon as you break up/move out, there is no other way to settle this matter (it doesn't matter whether you lived with the other parent of the child or not, you can petition for visitation rights right after the child was born if you think your contact is being limited).
It is important to remember that the court will never grant visitation rights that are general and non-specific (e.g. you want to pop in to your ex-partner's house whenever you feel like seeing your kids or you want to visit the children e.g. 4 times a month when you have time for it). If you file a petition, you need to specifically determine on which days and for how long you want to see your child/children (e.g. every other weekend from Friday 6 p.m. to Sunday 4 p.m., every Wednesday from 3 p.m. to 8 p.m., etc.). It's a good idea to think ahead and include in your petition specific dates of all kinds of holidays (Christmas, Easter, summer and winter holidays).
When you've filed your petition for visitation rights, the copy of it will be served on the other parent and they will have to respond to it in writing. The judge will surely try their best to make both parents reach an agreement and if that proves to be impossible, both parents and the children will be examined by the expert witnesses (psychologists) who will establish what's best for the kids (how often the parent requesting contact should see the children and for how long).
One more important point, though - even if your visitation rights have been established by the court and you come to pick up your child/children on a specific day and the child adamantly says she/he is not coming with you (or even cries), you can't force it. If you call the police to help you enforce your rights, they will most likely say they can't forcefully take the child from home. Therefore it's crucial to do one's best to maintain good relations with the children so that they are willing to spend some time with the parent not living with them.
Under Polish law paternity can be established in the following ways:
1. if a child was born during marriage or within 300 days of its termination (annulment, divorce, separation) the husband is deemed to be a child's father by virtue of law.
2. if a child was born out of wedlock, paternity may be established either by recognition of paternity or by the court.
Let's take a closer look at the first situation. Obviously the biggest problem will arise if the child is born to a married couple but the mother's husband is not the child's biological father (she had an affair). Under Polish law, the husband will be considered the child's lawful father with all the consequences that go with it. I've come across many cases when a woman got pregnant by her new partner and the child was born before the divorce was finalized or soon thereafter (but still before the lapse of 300 days after the termination of marriage). Even though the woman was in a new relationship and it was clear to all the parties involved who the child's father was, the woman's ex-husband was officially considered the child's father. Theoretcaally, he was obliged to financially support that child and decide about the most important matters concerning the baby. What can a man do in such a situation? He may bring legal action for the denial of paternity within 6 months from the time when he found out about the birth of the child by his wife, but no later than when the child turns 18. Usually it's the 6 months after the baby was born so it's important to act quick (in most cases the husband knows of his wife's pregnancy; if he's sure that the baby is not his, he can't affort to put off legal action until later - the court won't be forgiving if he fails to keep the 6-month-deadline for no important reason). On this note, if the child was conceived as a result of medical treatment (IVF) to which the husband consented, he won't be able to deny his paternity in the future .
Likewise, the child's mother has the right to bring legal action to deny the paternity of her (ex)husband within 6 months of the child's birth, so it's not only the presumed father who has the power to act. What's interesting it that also a child, upon turning 18, may bring legal action to deny paternity against the husband of his/her mother, but not later than 3 years after reaching the age of majority.
It's impossible to deny paternity after the child has died.
And now on to the second situation concerning recognition of paternity. First and foremost, if the paternity lawsuit is pending, the recognition of paternity is impossible, meaning that it's always one or the other.
Recognition of a child means that the biological father goes to the Registry Office and makes a declaration in writing that he is the father of the child. The child's mother has to confirm this fact within 3 months (usually the baby's parents go to the Registry Office together and in this way the child's paternity is established right away). An interesting fact - the mother may be as young as 16 to confirm the paternity of her child. The Head of the Registry Office may refuse to accept the declaration of paternity if he/she has doubts about the child's parentage (which is extremely rare, of course). It is also possible to recognise paternity before the Polish consul or a person designated to perform the consul's function (provided that at least one parent of the child is a Polish citizen).
Paternity can also be recognised before the court (the procedure is very similar to that before the Registry Office, only the father has to file a petition for recognition of a child and declare before the judge that the child is his and the mother will have to confirm it). Court recognition of a child doesn't happen very often.
Paternity cannot be recognised once the child turned 18, however, it's possible to recognise a child before it is born, but already conceived (also an extremely rare situation).
And now let's imagine the following situation: the child was born out of wedlock, the man recognised the child believing that he is their biological father but then, after a while, it turned out that the child is not his. What to do then? Fortunately there's is a legal remedy for it: the man who has recognised the child may bring legal action to establish invalidity of recognition within 6 months from the time when he found out that the child was not his (the same applies to the mother who can bring the same action; obviously such cases are rare as the mother usually knows who fathered her child). Such a lawsuit (for invalidity of recognition) may not be brought after the child has reached majority. Similarly to the procedure for denying paternity, the child, upon turning 18, but not later than 3 years after reaching that age, may also bring an action to declare invalidity of the recognition of paternity.
And now the last possible paternity-related scenario: the child was born out of wedlock, you know you're the child's father, but the mother will not confirm your paternity making it impossible to recognise the child in the Registry Office. What to do then?
Your last resort is to request that the court establish paternity of the child. Such a request may be submitted not only by you (the presumed father), but also by the child and the mother. During the court proceedings the court will ask both parties if it's possible that the presumed father really is the biological father of the child, most likely the judge will also hear some witnesses (probably closest family members or friends) on what they know about the parties' relationship. Sometimes both the mother and the presumed father confirm before the judge paternity of a child and that will be sufficient for the court. If, however, the parties argue about the paternity, the court will commission a DNA paternity test, which will be a deciding factor in the case. If the mother has been denying that the man is the child's father and the tests prove his paternity, she will most likely bear the costs of such tests (which are not cheap, roughly PLN 2000).
On a final note: if all deadlines have been missed and nobody can bring an action for the denial/establishing of paternity or for establishing the ineffectiveness of recognition of a child, your last resort will be asking the public prosecutor to do it for you. Public prosecutors are entitled to bring such an action without any time constraints, as long as it's necessary to protect the child's welfare or is justified by the public interest.
Sometimes it happens that a child's parent who is obliged to pay child support simply cannot do it. It can happen for various reasons - from not being able to work due to some medical condition to being permanently unemployed or serving time in prison. According to Polish law, it's not only the child's parents who have alimony obligation as it extends to relatives in straight line (e.g. grandchildren and grandparents) and siblings.
It's worth mentioning that alimony obligation doesn't concern children only - anyone, whatever their age, can find themselves in need of support and then their immediate family have a legal obligation to help out. Obviously, it's not like your grown-up siblings or grandparents have to give you money everytime you're broke, but if the situation is quite "extreme" and you're not at fault for creating it for yourself, you have the right to claim alimony from your relatives - the court will weigh up whether your claim is justified. Just to give you an example: sometimes the pension that the elderly parents receive is not enough to get by and if their children or grown-up grandchildren lead a comfortable life and yet refuse to voluntarily help financially, it's possible that the court will award certain (monthly) amount in favour of the elderly member(s) of the family.
What about the order of the relatives obliged to pay? Provisions of the Polish Family and Guardianship Code determine that alimony obligation applies to descendants (for explanation look below) before ascendants. This means that when you are in need you should first sue your grown-up children and not your parents for instance. Subsequently, alimony obligation applies to ascendants before siblings (you should first sue you parents and only if that's impossible, you can sue your siblings). If there are several descendants or ascendants, the obligation applies to those of the closest degree of relationship, so you can't sue your granddaughter when your daughter is still alive and capable of paying alimony.
Descendants are the relatives in straight line, who were born in the generations following yours (your children, grandchildren, grandgrandchildren etc.), ascendants are your parents, grandparents etc. (=generations born before you). As described above, the order of persons obliged to pay alimony means that if e.g. your mother finds herself in need of support, she should first request her children to help her out; only if that proves to be impossible, she can ask (=sue) her parents for support (she can't "skip" one generation and claim alimony from her grandparents right away, just because they are better off than her parents).
If it's you who have been sued for alimony by one of your relatives, it doesn't mean that you'll definitely have to pay and it's going to be exactly the amount requested by the claimant. The court will carefully check the situation of the person who claims to be in need of support and then examine your financial condition. If it turns out that you live from hand to mouth, nobody will order you to pay alimony for your relatives, especially if you have children of your own, who you need to support first.
In practice, it sometimes happens that minor children (represented by their mothers) sue their paternal grandparents for maintenance if the children's father doesn't pay at all or is capable of paying only a fracture of what is needed. However, in order for that to happen, the grandparents' financial situation has to be pretty good, as nobody will force them to pay regular amounts to their grandchildren if it could affect their ability to support themselves.
One last thing worth mentioning - the obligation of one spouse to maintain the other spouse after divorce, separation or after annulment of marriage comes before the maintenance obligation of the relatives. In plain words: if you have been married before (you got divorced or separated) and now your situation is so bad that you need financial support, you should first claim alimony from your ex-husband/ex-wife and only if that turns out to be futile, you can sue your relatives for support.
As of yet, only a man and a woman may enter into marriage in Poland. Same-sex couples cannot marry or make their relationship formal in any way. In Poland you can conclude marriage in two ways: you can do it in the Registry Office (civil ceremony) or you can have a church wedding which will also be legally binding. Moreover, it's possible to get married before a Polish consul while staying abroad.
What documents do you need to get married in Poland?
First of all - your ID and birth certificate. If you've been married before, you'll have to submit a document confirming that you're no longer married. You'll also be requested to submit a written declaration confirming that you are not aware of any circumstances preventing marriage. One additional requirement for the foreigners: they have to present a document confirming that according to the law of their home country (=of which they are citizens) they have legal capacity to enter into marriage. However, if obtaining such a document proves to be near impossible, a foreigner wishing to get married in Poland may petition Polish court to exempt them from submitting such a document. Needless to say, all the above mentioned documents have to be translated by a sworn translator.
If you want a registry wedding you can't have it instantly. You'll have to wait a month from the date of submitting a declaration on lack of circumstances preventing marriage (however, you may ask the Head of the Registry Office to allow the marriage before this deadline for important reasons). If you've decided to have a church wedding, you still have to go to the Registry Office first and get a certificate (something like a marriage license) confirming lack of circumstances preventing marriage, as well as decide on your and your spouse's last names after the wedding (and the last names of your future children). The certificate is valid only for 3 months so in that timeframe the church wedding has to take place.
An interesting piece of information - under Polish law it's possible to get married while being represented by an attorney so you don't have to be present during the ceremony - it'll be enough if your attorney is there to get married on your behalf.
The legal age for marriage is 18 for both men and women. However, a woman may be 16 years of age if the court allows her to get married (provided that it's in the best interest of the newly founded family - in plain words: when a girl is pregnant).
A marriage may be annulled by the court for the following reasons:
- if one of the spouses, at the time of the wedding ceremony, was unable to consciously express his/her intention (for whatever reason, e.g. under the influence of drugs);
- if one of the spouses entered into marriage due to an error as to the identity of the other party (=you thought you were marrying a different person);
- if one of the spouses got married under an unlawful threat from the other party or a third party and it is reasonable to assume that the theratened spouse could have feared serious personal danger to himself/herself or another person;
- a marriage may also be annulled due to bigamy, mental illness/retardation of one of the spouses, or the fact, that the marriage was concluded between direct blood relatives, siblings, immediate family-in-law or between the adopted person and the adoptive parent.
And what about the surname of the spouses after the marriage? There are three options: one of the spouses may assume the surname of the other spouse (both spouses end up with the same last name); each spouse may retain their current surname (the woman sticks with her maiden name) or one of the spouses (or both) combines their surname with that of the other spouse (double-barrelled surname). If you choose the last option, the surname may not be composed of more than two elements. The same applies to the surnames of the future children.
Under Polish law there is a legal institution called "separation", which is an alternative to divorce. The court may rule on separation when there has been a complete breakdown od marriage (just like with divorce - there are no longer any emotional, economic and physical bonds between the spouses). In case of separation the breakdown of marriage is not permanent (as is the case with divorce), so even though the spouses may legally be separated, there is still a chance for reconciliation. However, similarly to divorce, separation is not permitted if it would be detrimental to the welfare of the children of both spouses or if there are any other reasons why the decision to separate might be seen as contrary to the principles of community life (that last premise prevents separation very rarely).
It's important to know that if one of the spouses demands a separation and the other spouse wants a divorce, the court will rule on divorce (the court may ultimately deny it altogether but the case will concern divorce and not separation).
When examining the petition for separation, the court decided on which of the spouses is at fault for the breakdown of marriage (unless both spouses demand that the court waive the ruling on fault or both spouses want separation). In its ruling on separation the court also rules on parental authority over a minor child, parental contact with the child and the amount of child support/maintenance. A separation ruling has the same effects as divorce (most of all - it creates the regime of separate property between the spouses) with one exception: a separated spouse may not get married. Separated spouses are obliged to help each other, if the situation requires it. If one of the spouses ends up being found solely responsible for the breakdown of marriage (which resulted in legal separation), the other, 'innocent' spouse may demand alimony/maintenance (not for the children but for themselves), as long as the separation entails a considerable deterioration of financial situation of that innocent spouse.
Spouses who have already been separated may, after some time, demand that the court rule on terminating separation which means that they go back to being married just as they were before separation.
Many couples decide to legally separate due to religious reasons or when they feel there is still a chance for them to get back together. In many cases separation ultimately ends in divorce and becomes a transitional stage between the time when one of the spouses moves out and the time when both spouses (or one) decide that there are no chances for restoring the marriage.
According to the Polish Family and Guardianship Code, in case of any negligence towards a child the court may issue relevant restriction orders which are supposed to control parents who are failing at their role and protect the child.
The judge may in particular require the parents to behave in a certain way or send them to institutions or therapists providing family therapy and counselling. This is the mildest 'restriction' applied in situations where things like counselling can help (obviously, the court will check if the parents do what they were ordered, if they ignore the court's order harsher restrictions will be imposed).
The judge may also determine what actions cannot be made by the parents without the court's permission - this could happen when a child has their own money and/or property (e.g. inheritance) and there have been indications suggesting that the parents might mismanage the child's property. If the court finds out about it, it can forbid the parents to sell any of that property/spend the child's money.
The next restriction that the judge can impose is the supervision of a court-appointed custodian. Such a person will regularly check on the family and see if the parents fulfill their responsibilities appropriately. If the custodian believes that the parents are not fit to take care of their child, they will most likely request that the court take the child away.
If it's clear that the parents can't raise their child on their own (for whatever reason - it could be negligence, illness, addiction etc.), the judge will order that the child be placed into foster care or a children's home. However, if the parents' situation improves, it's possible to regain rights to their child.
When does the court issue the above mentioned restrictions? When it finds out about the problem in a given family (through other pending family cases regarding this family or when it has been reported by school, neighbours, relatives etc.).
If you are witnessing an alarming situation (maybe something happening next door) concerning the children, you should immediately inform the police or a local social welfare centre about your suspicions.
Polish law provides that a child (a minor) may be adopted if it's in his/her best interest. As for candidates for adoptive parents, they have to have full legal capacity (be full of age and not incapacitated) and have personal qualifications that make them good parents' material. It's necessary that there is a sufficient age gap between the child and his/her future parents, although the provisions don't determine how big this gap should exactly be.
As for foreign adoption Polish Family Code states that a Polish child may change his/her current place or residence in Poland to reside in some other country only if it's the only way to ensure that the child is raised in a family environment. This does not apply to situations where the child and his/her adoptive parents are related or the parents have already adopted a brother or sister of the child.
A child may be adopted by one person or by a married couple (jointly). Two people who are not married may not jointly adopt. However, it is possible that one person adopts a child and later his/her spouse adopts that child too (it will be considered a joint adoption as well). Adoption by same-sex couples is not permitted in Poland. If a person who is already married wants to adopt, he/she needs consent of the other spouse (if it's difficult to obtain that consent, the judge may agree to the adoption without it).
In Poland only the guardianship court may rule on adoption following the petition filed by a candidate parent.
If a child who is to be adopted turned 13, he/she will be asked about their opinion on the adoption. If the child is younger but understands the significance of adoption, the judge will also hear them to find out their opinion. Of course the judge will not ask the child about their opinion on adoption if he/she already considers themselves to be a child of the adoptive parent(s) or is too young to understand the process.
In order to adopt a child, it is necessary to obtain the biological parents' consent unless they have been deprived of parental authority or are unknown (or there are significant obstacles to reaching any agreement with them). Obviously, if the biological parents are unknown or it's difficult to obtain their consent the adoption proceedings will last much longer. In special circumstances the court may rule on adoption despite the lack of consent from biological parents if their legal capacity is limited (they're minors or have been partially incapacitated) and their refusal to consent to adoption is contrary to the wellfare of the child.
The provisions also provide that both biological parents may indicate the adoptive parent as long as the candidate is related to them and has agreed to the adoption.
Both parents may also agree to the adoption without indcating candidate parents which entails the loss of their parental authority and the right to contact the child. They can revoke their consent to adoption before the court, but not later than when the adoption case begins.
Biological parents may agree to adoption 6 weeks after the child was born at the earliest.
Adoption may be dissolved only for important reasons unless it is contrary to the child's welfare.
There are cases when it's necessary the deprive one or both of parents of their parental authority over a minor child. It can happen when a parent can't perform their parental authority permanently (e.g. left abroad without saying a single word and nobody knows where heshe resides, there's no contact with that person) or when a parent seriously neglects their obligations towards a child (e.g. she/he hasn't been in touch with their child and/or hasn't paid child support for years, abused them in any way, has a serious addiction etc.). The court may first impose on such a parent one of the restrictions described in article 8. What happens when parents fail at their responsibilities towards the child? as a last chance for them to get their act together. If, depite such restrictions, a parent continues to fail their child, the court will most likely deprive them of parental authority.
If both parents have been deprived of parental authoirty, their child is bound to be taken to foster care of the children's home. Such a child is then eligible for adoption. If a parent deprived of parental authority has mended their ways, the court may always restore their parental authority.
When a parent has been deprived of parental authority, they are still obliged to pay child support but they have no say in matters concerning their child. If it's not harmful to the child, such a parent may still have visitation rights but it doesn't happen very often. If the parent severely neglected their child, the court may prohibit meetings and communication with them.
It's worth stressing that deprivation of parental authority doesn't always happen in what we see as the most extreme cases (abuse, addictions, mental illness etc.). Quite often the parent living apart from their child chooses to pay child support but permanently loses contact with the child and in the end parental bond simply disappears. Especially when a small child hasn't seen their parent for a few years it results in forgetting them altogether which, in turn, may lead to the deprivation of their parental authority. In my practice I've had many situations where mothers filed such a petition and upon obtaining a judgement on deprivation of parental authority of a father, their current husband adopted the child.
This is one of the most asked question I get thorugh this website. Unfortunatetly in Polish law there are no set rules allowing calculation of child maintenance. Therefore it is impossible to say, even roughly, how much a parent obliged to pay is really going to pay. Each case is considered by the judge individually so if you know a person who has a child the same age as yours and pays PLN X, it doesn't mean that you are going to pay the same amount.
According to Polish Family law, there are two thing a judge is supposed to consider while establishing the amount of child maintenance: the child's needs (their expenses, costs of living) and the parent's financial capabilities. This means that if the parent representing the child claims an exaggerated amount the judge will check if all the child's expenses indicated in the petition are valid and justified and if you are capable of paying that amount. When you want to lower the amount of child maintenance you should focus on questioning the validity and necessity of the expenses listed in the petition and your financial situation (your other expenses and obligations, your own costs of living etc.). However, bear in mind that if you have a mortgage or a loan which financed the purchase of a house or a car, the judge will not take it into account as your valid expense having priority over child maintenance. In Polish law the child's needs always come first, so it's no use buying things on credit only to prove to the court that a significant part of your salary goes into monthly installments you pay.
Financial situation of the other parent representing the child will also be checked but the court rarely assumes that parents should bear the costs of the child's maintenance 50/50. The parent raising the child on a daily basis contributes more than the parent who pays child maintenance so the proportion of costs bearing by the parents often ends up being 30/70 or 40/60 (the parent not living with the child always paying more).
