My wife was named as representative payee for my son. We were seperated for a time and upon our reconsilation my mother refused to let us have our son back. We are involved legally and are in the court prcess. My mother went to ssdi and had them change the representative payee to her for my son. SSDI says she filed custody papers and they can not show them to me or my wife the former rep payee. They also state we cannot appeal? What can we do here? Can she get custody without us being notified or served court papers?
