If your grandchild’s biological parents are married, and the child did not live with you a year, then no, you can’t go to court and ask for visitation.
If your grandchild’s biological parents are not married but living together with your grandchild as a family, you can go to court to seek visitation BUT only if they signed a Recognition of Parentage (ROP) and filed it with the state registrar of vital statistics.
See the “Going to Court” section for more information.
