The relevance of the subject under study was conditioned by the fact that in Ukrainian judicial practice, both judges and experts who are members of the Scientific Advisory Council of the Supreme Court have differed in their opinions regarding the possibility of disqualifying an heir from inheritance based on the requirements of Article 1224, Part 1 of the Civil Code of Ukraine. The purpose of this study was to clarify such general legal issues as the applicability and extension of the presumption of innocence in civil proceedings, and protection against violation of this principle in the resolution of certain civil law disputes. The methods of analysis, synthesis, comparison, generalisation, and case study were employed to examine the decisions of national courts of general jurisdiction of various instances, the Constitutional Court of Ukraine, and the European Court of Human Rights. It was stated that the deceased heir – the accused, who inflicted serious bodily injuries to his father – the testator, as a result of which the latter died, cannot be considered as having no right to inheritance, based on the analysis of the content of Article 1224, Part 1 of the Civil Code of Ukraine. The study proved that a form of condemnation by public authorities and posthumous conviction outside the scope of due process of law would be establishment by a court in a civil case of the circumstances of intentional deprivation of the testator’s life by an heir, where the former died at the time of the consideration of a civil dispute. It is unacceptable for a civil court to rely on the circumstances of the indictment and the grounds for closing criminal proceedings against a deceased defendant – an heir. Only a guilty verdict establishes a person’s guilt. If it is referred to in other procedural decisions, it is probable that the person will be socially stigmatised. A civil court may not assume the powers of a court that are exercised only in criminal proceedings when resolving a dispute over inheritance. The practical value of the study lies in the development of arguments for the court and participants in the trial
