The identification with Radoslabos Chlapenos (Radoslav Hlapen) is doubtful. Mihailo Dinić identified Radoslav with „Rado(a)sclavus filius de jupan Vratisclavo“, who is attested in the Ragusan archives under the year 1319. Some scholars supposed that he was the same person as „iupan Rodosclauo“, who appears in the charter of Vladislav, the son of the former Serbian King Dragutin, adressed to Ragusan authorities from the 25th October 1323. He is mentioned in the chrysobull charter of the Serbian Emperor Stefan Uroš IV Dušan in favour of the Monastery of the Holy Archangels Michael and Gabriel near Prizren. Attested also in the ktitorial inscription and the wall painting in the Church of the Presentation of the Virgin in Kučevište. The wall paintings in Kučevište can be dated between 1331 and 1334. He held the position of župan. Apparently the son of Marena. He figures in the inscription of the founders of the Church of the Presentation of the Virgin in Kučevište. His portrait has been preserved only in fragments on the northern wall of the narthex in the same church. The Serbian King Stefan Uroš III Dečanski donated the village Klьčevišta (Kučevište) to Župan Radoslavь. Župan Radoslavь bestowed the village of Klьčevišta and its church of the Mother of God together with the hamlet Brodcь, vineyards, fruits, bought estates and all rights to the Monastery of the Holy Archangels Michael and Gabriel near Prizren. The Serbian Emperor Stefan Uroš IV Dušan confirmed the gift of Župan Radoslav in the chrysobull charter for the monastery (I ješte priloži carьstvo mi crьkvi carьstva mi Arhaggelu sь hotěnijemь ljubimago vlastelina carьstvu mi Radoslava župana, selo Klьčevišta, sь crьkoviju Svetyje Bogorodice, i sь zaselkomь Brod᾿cemь, s vinogrady, sь ōvoštijemь, i s kupljenicami, i sь vsěmi pravinami, kako piše u hrisovulě Klьčevišt᾿komь što jestь zapisalь roditelь carьstva mi gospodinь kral).
