Was your wife on the deed? If she was there would need to be another deed conveying away your interest.
If she wasn't, it might behoove you to get a quit claim from her showing she expressly disclaims any interest (a quit claim doesn't assert you actually have any interest. This is one of the few times it's a good idea).
When you sell the property, if the title search/insurer shows you were married when the property was acquired, a copy of your divorce decree and property settlement would probably suffice, a quit claim would be golden.
