The scientific article examines the problems of the operation of legal mechanisms for the recovery of funds related to the military aggression of the occupying State. The national legislation of Ukraine notes the expediency of the court procedure in such cases according to the rules of civil procedure since the talk is about civil legal relations. Such legal relations are usually considered by courts of civil jurisdiction regarding litigation related to compensation for damages and material losses caused by Russian aggression. At the same time, civil proceedings cannot be recognized as the only procedure for restoring violated rights, freedoms and legitimate interests committed during military aggression. In this regard, the paper notes the importance of determining the court jurisdiction and jurisdiction of such cases, developing the rules of evidence and ensuring the right to professional legal assistance, as well as procedures for executing court decisions. At the same time, the peculiarities of providing legal assistance in the conditions of martial law and the difficulties faced by the interested persons are characterized. It is noted that the institution of reparations should not be considered sufficiently developed in international legal regulations and the national legislation of the State that suffered from military aggression.
