If neither parent wants to permit the grandparent visitation, unless and until the grandparent files a formal request with he court, the grandparent has NO visitation rights. If he wants to let his Mom see the kids during HIS time, that's between him and his mom; if you want Grandma to see the kids during YOUR time, that's between her and YOU; but if she wants time that neither of you wants to give her, she's probably out of luck.
