Greetings. Yes, there is such a thing as a post nuptual agreement. No, I do not believe a notarized document stipulating the agreement would be sufficient. The terms of any contract must be in line with the statutory authority. The requirements for a post nuptual agreement are too long to list here.
I would suggest that if you have any concerns, not to sell the house. Best of luck.
