If you are entitled to your deposit money back (and from what you are telling us here, the bank conceded that you acted in a timely fashion), then the bank should sign the release within a reasonable time. Although most contracts provide that the deposit money be returned upon cancellation (in a timely fashion), the contracts do not include the necessary escrow instructions that would trigger an automatic release of the funds upon cancellation. This is the reason why the title company can't send you the money until the bank signed the release form. Banks act very slowly and they know that not much will happen to them if they don't act quickly. I would suggest you have your agent call the bank daily and if they don't sign the release by the end of a week, hire an attorney. It's unfortunate that you may have to spend money on an attorney to get your deposit back, but your options are unfortunately limited. Good luck to you.
