Condemnation before the maturity of the claim refers to exceptions to the rule according to which the court can order the execution of a certain act only if it became mature until closure of the hearing. These exceptions include cases when the court accepts a request for maintenance, a judgment binding the defendant to hand over or take over things given for rent or lease before the termination of those relations, the plaintiff complaint for judgment before the maturity of the claim on the basis of a proven legal interest, fair monetary compensation in the future non-property damages and interests. Except in the case of a condemnatory complaint before the maturity of the claim based on Article 186.c of the Croatian Code of Civil Procedure (ZPP), the plaintiff's legal interest is presumed because it is based on legal authority or court practice. In case of filing a lawsuit under Article 186.c of the ZPP, the plaintiff must prove his legal interest. In this work it is investigated the practice of Croatian courts in the context of each exception, and it was concluded that in certain cases the practice of the courts is regular, while some cases are very poorly represented. In the case of maintenance and interest, condemnation judgments are regularly passed before the maturity of the claim, while the practice of the courts is uneven in relation to rent and lease and fair monetary compensation. Judges and their interpretation of legal provisions and concrete facts in each case play an extremely important role
