Just because a divorce has been "settled" already, it does not mean that there are not certain things that you can do to alter it after the fact. This might be in relation to real estate or alimony.
Grandparents always have a special place in their heart for their grandchildren, and it can be heartbreaking if for some reason they are having difficulty in attaining the rights to visitation. Perhaps your child does not have custody of your grandchildren and the other parent is limiting access, or perhaps you are estranged from your child but you still want to maintain a healthy relationship with your grandchild. Whatever the reason, it should be possible for you to be a positive influence in your grandchildren's lives.
