Grandparents sometimes have visitation rights in the state of California, according to the California Judicial Branch. There are required circumstances that must be met for these rights to be awarded.
To gain visitation rights the grandparent must demonstrate that he and the child have a preexisting bond and that the benefit of continuing this relationship does not outweigh the parents' rights to make decisions about their child, explains the California Judicial Branch. Visitation rights for grandparents are normally awarded only if the parents are no longer married. Exceptions to this rule include separation of parents, a missing parent, an adoption or a signed petition by one of the parents pushing for grandparent visitation.
