By law grandparents have a right to petition for visitation when the parents of the grandchildren are divorcing. Grandparents could petition for visitation even if the parents are happily married by showing it is in the best interest of the child. You need show you have a bond with the grandchildren, you have been in their lives up until this point, that there will be no negative impact on the child's relationship with their parents if they visit you, and that you can have at least a neutral realtionship with the parents so the children are not affected.
