A more thorough explanation:

Domestic-relations law, also known as family law, is a set of laws that deal with issues related to families. This includes marriage, divorce, adoption, child custody and support, child abuse and neglect, paternity, and juvenile delinquency.

For example, if a couple decides to get a divorce, domestic-relations law will govern the process of dividing their property and determining child custody and support. Similarly, if a child is being abused or neglected, domestic-relations law will provide legal protections and resources to ensure their safety.

Domestic-relations law also encompasses broader legal areas such as wills and estates, property, constitutional rights, contracts, employment, and finance as they relate to families. For instance, if a family member passes away, domestic-relations law will dictate how their assets are distributed among their heirs.
