The percentage of successful collections of alimony for children in Poland is very low. This serious problem can raise the question: What can the Church do, using its own legal means, to help increase the fulfillment of court-ordered provisions for children? Answering the question, the article discusses the bans on marriage. The fist is a ban of assisting, without the permission of the local Ordinary, at marriage of a person for whom a previous union has created natural obligations towards children (can. 1071 § 1). The second is a prohibition of entering marriage imposed by the local Ordinary in a specific case for a time, for a grave reason and while that reason persists (can. 1077 § 1). There is also in the paper a presentation of alimony in Polish state law and a supplement that treats about a prohibition of marriage appended to the judgement by the tribunal in annulment case (can. 1684 § 1).
