The relevance of this work is due to the fact that genomic and genetic information are special objects of research for law, and they require a systematic approach able to regard as many features of such information as possible. It seems that legal modeling is one of the key legal research methods capable of coping with this task. The purpose of this study is to consider the method of legal modeling in the study of genetic and genomic information. The paper outlines some aspects of its application, its advantages for interdisciplinary research. It has been established that legal modeling is able to regard all the factors influencing the legal regulation of genetic and genomic information. The staging of legal modeling, which implies determining the object and the subject of legal modeling, setting goals and objectives, proposing and testing a hypothesis and formulating a legal model, has been noted.
