47. Family Law
The area of family law intersects with divorce law, but is much broader in scope dealing with on-going issues such as child custody, parental rights, and alimony. Other areas might include pre-nuptial agreements, domestic partnerships, same-sex unions, and adoptions.
Lawyers specialize in areas of their choosing, so not all divorce lawyers choose to handle all areas in family law. Similarly, an attorney practicing family law may choose to focus on child custody and adoption and have nothing to do with marriage dissolution. Either way, divorce comes under "family law", but it is only a part of it.
