Foreclosure with name on mortgage not deed

[Jiva Segaran]

Aloha, I found a distressed property that I am trying to purchase from a gentleman but he is only on the mortgage and not the deed as the wife got it in the divorce.however she is in foreclosure now and poorly affecting his credit. Anyone know what his rights are (if any) ? I want to help him out and buy the property at the same time but not sure of a good way to do this without the wife's involvement. I told him to convince her to sell to me so she can walk away with some money and we can help with relocation. Then id give him some money for his troubles and all happy. But doesn't look like they are amicable.
