My boy friend was involved in a car accident about 6 years ago and won a big settlement of about 1 million dollars. Unfortunately though he has lost his mental capacity to function and so he had to move in with his mother and left me alone with our 1 year old son. His mother took all the money and my son haven't received even a dime. What can I do so our son can get child support since his grandmother took all the money. I need help please.
