This scientific article presents a study of the problem of indeterminacy of the conceptual and categorical apparatus in the field of the judge's integrity in the modern legal system.
 It is noted that in the modern legal understanding, the integrity of judges is a fundamental ethical and normative aspect that determines the high standard of professional behavior of judges in the context of the exercise of judicial power. This principle includes not only the dispassion (impartiality) and objectivity of the judge in the decisions made, but also his ability for self-reflection, ethical awareness and independence from the influence of external factors.
 The conceptual-categorical apparatus is the main component of the legal technique, which contributes to the precise and clear expression of legal norms and ensures their effective implementation in society. In the praxeological aspect, questions of integrity of judges arose in many cases when competent authorities did not confirm the appropriate level of integrity of a judge or a candidate for this position. This is due to the essential problems of the imperfection of the legislation, since the concept of «honesty» in the legislation is not clear. The legal system and the legislation system must possess and operate in clear and unambiguous terms to avoid misunderstandings and ambiguous interpretations or recommendations regarding the interpretation of norms.
 The main signs (characteristics) of the integrity of judges include, in our opinion, the following: impartiality and objectivity, the independence of a judge, which is a fundamental principle of judicial activity, which ensures his dedication to the use of the law and the result of the influence of external factors that can reveal objective consideration affairs; honesty and integrity; high level of knowledge and competence; appropriate level of professional ethics; the opportunity to bear public, legal and moral responsibility.
