The study aims to investigate Ukrainian residents’ access to justice in cases where internally displaced people are compelled to file an appeal with the court against decisions made by State authorities that infringe on their rights to social security and pension support. The study makes use of classification and analogy techniques. Analysis and synthesis were the primary research methodologies. The formal legal method – specifically, the procedures of deduction and systematization – is one of the unique legal techniques employed. The definition of the term “internally displaced person” in the context of international law is the study’s output. It was done to become familiar with the key international agreements that define the legal status of internally displaced people. Using instances from other nations, the issue of internally displaced people within a nation was identified. This occurs during times of war or other situations that endanger the safety of individuals at their place of residence. It emphasizes integrating international best practices to safeguard these people’s rights inside national legal systems, particularly regarding social and pension provisions. It is determined that administrative procedures must be improved.
