Family law as a legal category within the context of the U.S. can be understood to potentially refer to a wide range of various subjects of law. In this regard, nearly any subject of family life can be provided for by the structure of family law within the U.S. One way of understanding the various categories in which family law can be placed concerns the particular stage of the relationship between the family members involved in the case.
As such, family law might deal with how the marriage, or otherwise enforceable legal relationship, is initiated under law. After that point, family law can be understood as dealing with various issues arising at some point for the duration of the family, including those dealing with the children, biological or adopted, of the people in the relationship. Moreover, family law can also deal with how the family involved in the case comes to an end, such as through divorce.
