Introduction: the article provides theoretical justification of the concept "legal form" in family law. It is noted that the legal form has already been defined by rule of law and the developed family relations in society, but so far the legal form as an element of scientific cognition of family law has not attracted attention of scientists. Purpose: to consider the legal form in family law applying scientific developments in civil law. To present the author's definition of the legal form as a general concept and of the legal form of a subject's activity as a special concept. Methods: some methods of formal logic - analysis and synthesis, induction and deduction, in their connection with extrapolation, argumentation, generalization, analogy have been used. Results: with the help of these methods, the legal form is defined and identified in family law. The authors have managed to unite the doctrines which are already available in civil law concerning the legal form and to make independent conclusions within the branch of family law. Thus, the authors focus, first of all, on types of the legal form, their features, and distinguish between the legal form in civil and family law. Conclusions: the data received as a result of the research can be taken as a basis for the theory of the legal form in family law.
