Since our father died, our older brother is keeping secretly their bank accounts. He just recently stole my mother's saving's account via electronic transfer, and has not been depositing her interest checks into her account for the past several years.
If this has been taking place over several years, I wonder if he was handling the funds with your father's consent, or what the situation is.
Did your father leave a will? Who's the Personal Rep or Executor? Or was everything left to your mother?
