Starting from the principle of state continuity and fact that Yugoslavia was recognised in the League of Nations in its old form, Josip Broz Tito, president of NKOJ, and Ivan Šubašić, head of the Yugoslav royal goverment, agreed that "King Peter II should not enter the country until the peoples make their decision about it and that the Regency should exert royal authority in his absence," that a joint Government should be formed and they agreed on its composition.

There were two annexes to this agreement. The first sets the deadline for the holding of elections for a date after the final liberation of Yugoslavia, in accordance with the Law on Elections for the Constitutional Assembly. It was said that AVNOJ should be in charge of the legislative and government of executive functions until the establishment of the constitutional assembly. The second annexe regulated the position of the regent and administration of the king's estate.

On March 2, 1945 King Peter II appointed the royal regents and transferred his authority to them until the election for the Constitutional Assembly, which was supposed to decide on the form of authority. Through the Regency Yugoslavia was represented abroad in its old form.

Under the Belgrade Agreement and recommendations of the Crimea Conference, on March 7, 1945 the provisional people's government of the Democratic Federative Yugoslavia was formed. Its establishment marked the end of the previous parallelism, "dualism" or "duality" of governments. The establishment of the provisional government was preceded by the dissolution of the royal Yugoslav government and NKOJ.
