Dear JACUSTOMER - I wish I had an easy answer for you but whenever the parents agree as to who can or cannot have contact with their children then the law will not force them to do otherwise. Grandparent visitation rights exist in situations where the child of the grandparent is deceased or otherwise unavailable and the in law parent will not permit the visitation. So if your son were deceased or totally out of the picture you could file a motion for grandparent visitation.
In this case your only option is to repair your relationship with your son. I don't know if there is possibly a third party who could act as a mediator between you and your son but that may be a good approach. Legally your son and daughter in law are within their parental rights to deny you visitation. I am also a grandparent so I certainly understand your pain and anguish in this situation.
