Active in the vicinity of Serres between 1341 and 1375. He was οἰκεῖος and δοῦλος of the Serbian Emperor Stefan Uroš IV Dušan, 1355. 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 (ὁ οἰκεῖος τῶ κραταιῶ καὶ ἁγίῳ ᾑμων αὐθέντη καὶ βασιλεῖ Δοῦκας ὁ Κορέσης εἰδέναι ἀκριβὼς τὰ σύνορα καὶ προνόμια τῆς ἁπάσης αὐτῶν γῆς). He signed the document, which was issued by Iakobos in December 1355 (Ὁ δοῦλος τοῦ κραταιοῦ καὶ ἁγίου ἡμῶν αὐθέντου καὶ βασιλέως Δούκας ὁ Κορέσης). He appears in another document of Iakobos, the Metropolitan of Serres, for the Hilandar Monastery from November 1360. Several local nobleman, among them also Duka Koreses, who lived in the vicinity of the metochion Saint Nicholas in Kamenikaia, took in possesion some of its estates. Iakobos returned the unjustly annexed lands to the Hilandar Monastery (καὶ πρῶτον μὲν εὕρομεν ὅτι ἀπὸ τούτων ὑφείλετο ὁ Δούκας ὁ Κορέσης καὶ κατεῖχε, προβαλλόμενος ἐξ ἀγορᾶς τοῦτο κεκτῆσθαι). Dukas Koreses was more than thirty years in dispute with the Alopu Monastery on Mount Athos over a land in Klopotitza. The judicial panel summoned by Theodoros, the Metropolitan of Serres, confirmed in August 1375 the claim of the convent of Alopu on Mount Athos on the land Klopotitza. The decision was realised only after the end of the Serbian rule, since Duka Koreses was courtier and supporter of the Serbian rulers.
