If your grandchild’s biological parents are married, and the child did not live with you for 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 above for more information.
