This study represents an attempt of author to describe the open border issues among Serbia and its neighboring states, successors of former SFR Yugoslavia. Imprecision of defining internal
borders in the SFRY led in the post-Yugoslav period to certain disagreements between the successor
states. This has contributed significantly the principle of uti possidetis which broad interpretation of
the International Court of Justice in border dispute between Burkina Faso and Mali in 1986, established universal significance in relation to the limited regional significance which the principle had
during the process of decolonization in the second half of the 20th century. In the succession case of
Yugoslavia, the basis for the application of the principle of uti possidetis remained therefore legally incomplete. Namely, the principle uti possidetis is not able to resolve all boundary problems between Serbia and its neighbors, why in the future it will be necessary to achieve a compromise on all
outstanding border issues in accordance with international law
