Interesting read regarding grandparent rights. The Court of Appeals upheld a Dependency Court order granting a grandmother visitation rights. It’s a case right here in Los Angeles County involving DCFS.
Grandparent rights come up relatively regularly, but I don't believe that this case will necessarily significantly broaden the law that currently exist. In the absence of DCFS involvement or a Dependency Court case (such as in this case), or the consent of the parents, grandparents typically have limited, if any custodial rights to their grandchildren.
