Probably nothing. Grandparents' visitation rights are statutory. There is no statutory right to a visitation order when the family is intact. Only children that are illegitimate, or have divorced or deceased parents may be the subject of court-ordered visitation. The reason is that generally, the right to be free from governmental interference in everyday life is a constitutionally protected right. Therefore, unless the State has some compelling interest (such as protecting a child that is illegitimate, has a deceased parent or is a ward of the Court through divorce) it cannot order visitation.
