If the house was awarded to you, your divorce settlement should contain a requirement that he sign a quit claim deed at your request. You can get that paperwork from your lender. If he refuses to sign, you'll need to go back to court and charge him with comtempt.
These orders don't expire. It took my ex 1 year to present me with a quit claim on the house and 4 years before she asked me to sign her car over to her.
