Introduction. Current Russian legislation regulates the procedure for establishing a legal connection between a born child and his or her father, however, in practice, problems with applying the presumption arise when establishing paternity. The problem is caused by the fact that it is the marital relationship of the child’s parents that establishes paternity, and not any biological relationship between the child and the father. In the context of family law, perhaps the most significant legal presumption is the presumption of paternity.
