I am sorry for your situation.  I think that it would be best to get an attorney involved to move things along.  Statutes that deal with the rights of Grandparents generally surround issues of visitation when couples divorce or a party remarries, etc.  It is my understanding that Arkansas specifically grants great-grandparents the same rights as grandparents. Grandparents or great-grandparents may request visitation rights if the parents' marital relationship has been severed by death, divorce, or legal separation. In addition, visitation may be requested if the child is in the custody or under the guardianship of a person other than a natural or adoptive parent, or if the child is illegitimate. In the case of an illegitimate child, a paternal grandparent may request visitation only if paternity has been established in court. So this will get you to see your grandchildren but that is not what you really want.  You may want to start a petition for custody of the children.  You seem to be the right choice here to give them a stable environment with a family member but your son could be an obstacle to that. Seek help.  Good luck.
