His mother and his family are attested in the charter. He and his family erected the Church of Holy Saviour (Sveti Spas) in Prizren. The Serbian Emperor Stefan Uroš IV Dušan donated the Church of Holy Saviour in Prizren with all its possessions to the Monastery of the Holy Archangels Michael and Gabriel near Prizren. He offered Mladěnь the Church of Saint Andrew (or the church, which belonged to Andričь) in Ōhrid instead. The property exchange was confirmed in the charter of the Serbian Emperor Stefan Uroš IV Dušan for the Monastery of the Holy Archangels Michael and Gabriel near Prizren in accordance to the law: church for church, village for village, vineyard for vineyard and mill for mill (I simь ōbrazomь zaměnihь crьkvь Spasa u Mladěna Vladojevikja i u matere jego i u vsega rodьstva jego, rek’še h’titorьst’va ego, i za vse sela s ljud’mi i zemlomь i s vinogradi i sь vsěmi pravinami iže se nahoděše crьkve te, ili u gradu ili u župě ili indě gdě ljubo, nihь volomь i nihь hotěnijemь, a ne někoju nuždeju, zaměnihь i dahь zaměnu u Ohridě An’dričju crьkvь za crьkvь, sela za sela, vinograde za vinograde, mline za mline i što jestь imala crьkvь tazi ōt prěžde, vse mu da carьstvo mi, i zapisahь Mladěnu i jegově materi da si drьže vь město segazi u baštinu kako jestь drьžalь Spasa takozi da si drьži Andričju, a Mladěnь ni jegovь rodimь da vekje ne poište onezi baštine, ni crьkve Spasove iže jestь u Prizrěně).
