The present study is devoted to the procedure of gender reassignment in Czech law. The reason for consideration in this area is the demand – formulated by the judiciary – for the introduction of amendments to Section 29 of the Czech Civil Code, significant from the perspective of persons with gender identification disorders. Namely, it is pointed out, among other things, that it is necessary to repeal the obligation of persons with gender identification disorders to undergo gender correction surgery. For this reason, and in view of the previous position presented by representatives of legal science in the Czech Republic, the current legal regulations relating to the procedure of gender reassignment in Czech law were analyzed. The study ends with a conclusion, in which the proposed normative solutions in the area of legal and medical aspects of the gender reassignment procedure in Czech law are critically evaluated.
