Children in California can now have more than two legal parents.
Last week, Gov. Jerry Brown signed legislation addressing the shifting family structure, including situations in which same-sex couples have a child with an opposite-sex biological parent.
Conservative groups fought the law, calling it an attack on the traditional family.
Brad Dacus, president of the Pacific Justice Institute, said in the long run, "the ones who are going to pay the price will be children...having more than two legal parents will create the potential for greater conflict over what is best for a child and result in more complicated court fights."
The law allows three or more parents to share the custody and financial responsibilities of raising the child.
