For his service, he was awarded possessions in Navahrudak and Lida. Kaributas continued to support Jogaila: he witnessed the Union of Krewo and fought in the Lithuanian Civil War (1389–1392). After the Ostrów Agreement, he refused to recognize Vytautas' superiority and was defeated in a battle near Lida in early 1393. Kaributas was imprisoned and stripped of his possessions. However, he was soon released and given Zbarazh, Bratslav, and Vinnytsia. Severian Novgorod was given to Fedor, son of Liubartas. Kaributas appeared last in written sources in 1404 during a military campaign waged by Vytautas against the Principality of Smolensk.
