He donated a land to the Asomatos metochion, which belonged to the Monastery of Saint John Prodromos near Serres. The Serbian Emperor Stefan Uroš IV Dušan confirmed the gift of Alexios to the monastery in a prostagma charter from September 1352. He was in the commision, which was entrusted by Iakobos, the Metropolitan of Serres, to delimit the metochion of the Philotheu Monastery in Kremna and Tzainu. He signed the document, which was issued by Iakobos in December 1355 (Ὁ δοῦλος καὶ θεῖος τοῦ κραταιοῦ καὶ ἁγιου ἡμῶν αὐθέντου καὶ βασιλέως Ἀλέξιος Δούκας Ῥαοῦλ † Ὁ ΜΕΓΑΣ ΔΟΜΕΣΤΙΚΟΣ). He had a long-term dispute with Stephanos Kalothetos, who was the father of Angelos. When Angelos died, Alexios asked Kalothetos to fulfil his obligations promised at the time of wedding. Kalothetos involved the monks of the Batopedi Monastery in the case by storing the valuable things in their monastery. The Serbian Empress Jelena (Helene) issued an horismos that allowed Alexios to demand the valuable things or an equivalent amount of money from Kalothetos. Since Kalothetos did not pay the entire sum, Alexios attacked the estates of the Batopedi Monastery. The monks had to pay the rest of the sum to Alexios. The conflict of all participants in the case was definitively brought to an end by the decision of the general judge of the Romans Theophylaktos Dermokaites.
