Ex wife kept house per the divorce decree how can I get my name off the deed/title/mortgage

Most divorce papers awarding property to one of the parties also says the parties are responsible for completing any paperwork necessary to carry out the terms of the judgment..

I suggest you visit the county recorder and ask how to get your name off. The likely answer is to file a QUIT CLAIM DEED or, if available, AN INTERSPOUSAL TRANSFER DEED. You will need the legal description of the property but the Recorder can get that for you.

There is no way you can get your name off the mortgage obligation unless the mortgage lender agrees - and it almost never will. If it made the loan to you and not to your wife, there is nothing you can do to force it to substitute your ex-wife for you. The lender was not a party to your divorce, and never agreed to the arrangement you and she made.
