[Legal status as at January 2019]

Parents are obliged to maintenance allowance for a child who is not yet able to maintain themselves, unless the income from the child's property is sufficient to cover the costs of its maintenance and upbringing. It means, that a child needs to pay alimony even when he is over the age of 18 but, for example, he / she is still learning (of course, the child has no right to abuse his right, eg through so-called "eternal studies"). It should also be remembered that the obligation to pay alimonies may continue even until the child's death, when they never become independent (eg as a result of illness) or when they lose their ability to maintain (eg as a result of an accident).

Although the parents are obliged to alimize the child first (before other relatives of the child, such as grandparents), if the child (it is adults) marries, first of all, he must seek maintenance from his spouse (eg when the daughter is studying marries a man who has enough income to support her and her parents do not have to keep her daughter).

Looking back to the child, alimony is due only when it is born, but it is possible to take care of the child in the middle of pregnancy. A wife may demand larger maintenance from her husband due to her pregnancies.

On the other hand, a woman who is not married can demand from her father a conceived child that the man would spend the right amount of money for the three months during the delivery and the costs of child maintenance for the first three months after birth before the child was born. The date and method of payment of this sum is determined by the court. Generally, a father who is not a mother's husband is obliged to contribute in a size corresponding to the circumstances to cover expenses related to pregnancy and childbirth and the cost of three months of mother's maintenance during the delivery. For important reasons, the mother may demand her father's share in the costs of her subsistence for more than three months. If, due to pregnancy or childbirth, the mother incurred other necessary expenses or particular property losses, she may demand that the father cover the relevant part of these expenses or losses. Claims above are also due to the mother if the child was born dead.
