The article is devoted to the formation of a cognitive framework of a legal corporation, to the development of common professional ethical guidelines and creation of standards the legal profession in the context of achieving the objectives of the legal profession to ensure the person's right to qualified legal assistance (art. 48 of the RF Constitution). The author ground his opinion on the need for a systematic and interdisciplinary approach to solving these issues. Formation of cognitive framework of a legal corporation as the core of corporate culture, presupposes the existence of appropriate tools and mechanisms. The above mentioned means are corporate language (as the basis of corporate culture), the standards of the legal profession (as a form of fixing the rules of the profession) and ethical (disciplinary) precedent (as one of the possible mechanisms of development of trade rules). Based on conclusions about the lack of a systematic approach to corporate language, the author concludes that there is a need to standardize lexical unit at a corporate level, as well as the process of its formation and implementation. The article defines the basic requirements for the terminological system and proves the necessity of developing standards of the legal profession, the introduction of case approach and, in particular, disciplinary precedent. The author also determines benefits of the implementation of a disciplinary precedent as one of the possible mechanisms for the formation of the rules of the legal profession and cognitive bases of a legal corporation.
