The subject of the right in international law is one of the subjects that occupies a distinct importance in international law, which many people interested in international law avoid delving into due to its accuracy, first, and the difficulties surrounding the subject, second, due to the problem of conflict with some of the interests of states that they are keen to defend, regardless of whether they are consistent with the idea of the right or not. The problem of the study arises in an attempt to formulate a special theory of the right in international law, due to the special nature of international law, which is subject, as a general principle, to international decentralization and the freedom of states in their international actions, except with an explicit restriction. The research was divided into two sections, the first of which dealt with the right in domestic and international law, while the second section dealt with models of the right in international law, namely recognition and the right to self-determination.
