Family law discusses information about such topics as marriage, divorce, adoption, child support, and child custody. Many of these laws are similar to those of other states, with minor differences. For instance, California does not require a blood test or a waiting period for couples wishing to get married, as many other states do. Also, California allows same-sex couples to get married. As a practice area, family law also includes child abuse, domestic abuse, stalking, and protective orders (all of which cross over into criminal law).
