In 1947, Đujić was tried and convicted of war crimes in absentia by Yugoslavia's communist government.
He was found guilty of mass murder, torture, rape, robbery, and forcible confinement, as well as collaborating with the German and Italians.
He was accused of being responsible for the deaths of 1,500 people over the course of the war.
Between 1947 and 1949, Đujić lived in Paris, before emigrating to the United States.
Many of his former Chetniks followed him.
Following his arrival in the United States, Đujić and his fighters played a role in the foundation of the Ravna Gora Movement of Serbian Chetniks.
Later, he enraged some in the Serbian diaspora when he endorsed a communist-appointed Patriarch as the leader of the Serbian Orthodox Church.
Nevertheless, he remained strongly opposed to Yugoslavia's communist government.
Đujić retired to San Marcos, California.
In 1988, the Yugoslav authorities unsuccessfully sought Đujić's extradition from the United States.
By this time, Đujić was the oldest surviving leader of the wartime Chetniks.

On 28 June 1989, the 600th anniversary of the Battle of Kosovo, Đujić granted the title of vojvoda to Vojislav Šešelj.
He further ordered him "to expel all Croats, Albanians, and other foreign elements from holy Serbian soil", stating he would return only when Serbia was cleansed of "the last Jew, Albanian, and Croat".
Šešelj was at the time an anti-communist dissident.
The writer and political analyst Paul Hockenos subsequently described Šešelj's activities in the Yugoslav Wars as "a man whose killer commando units operating in Croatia and Bosnia carried on the very worst of the Chetnik tradition."
Šešelj later became the leader of the Serbian Radical Party, a government coalition partner of Serbian President Slobodan Milosević.
In 1993, Đujić remarked: "[I condemn] Vojislav Šešelj who, by openly siding with the Socialist Party of Serbia, who are Communists who have only changed their name, has sullied the name of Chetnikdom and Serbian nationalism."
In 1998, Đujić publicly stated that he regretted awarding the title to Šešelj. "
I was naïve when I nominated Šešelj [as] Vojvoda; I ask my people to forgive me," Đujić remarked. "
The greatest gravedigger of Serbdom is Slobodan Milošević."

According to the International Criminal Tribunal for the former Yugoslavia (ICTY) testimony of Croatian Serb leader Milan Babić, Đujić financially supported the Republic of Serbian Krajina in the 1990s.
Đujić's wife died in 1995.
In 1998, Biljana Plavšić, then President of the Republika Srpska, presented an honorary award to Đujić.
Plavšić was later indicted by the ICTY and convicted of crimes against humanity.
