Legal Question in Family Law in California

Re: Visitation Rights

Granparents, by statute, have a right to SEEK visitation rights. Aunts do not. A grandparent will be denied visitation rights if the parents are married and living together and do not want gp to visit or, if parents apart or one is dead, gp visitation is found to be not in best interest of child. Question will be: what was the gp's involvement with the child before the request and was it negative or positive?
