This article presents a comparative analysis of the linguistic, stylistic, and structural features of official document texts in the Uzbek and Turkish languages. The study examines state documents, official correspondence, directives, orders, contracts, applications, and decisions as illustrative materials. The terminological systems, syntactic structures, lexical units, and stylistic norms of document texts in both languages are identified, and their similarities and differences are analyzed on a scientific basis. The results reveal the common Turkic roots of Uzbek and Turkish document language, contemporary trends in the development of official style, and factors related to national language policy.
