OOOOPS, sorry I misread your original post.

NOW I understand that he purchased the property WHILE you were married....And at closing you signed a quit claim deed.

Sorry, but a quit claim deed does not relieve you of financial responsibility that may occur during the marriage, it only removes your right to claim ownership or partial ownership of the property later.

Those folks can easily name you in the suit-it will cost them nothing to do so, but increase their chances of recovery where they will go after you both or the person most likely to pay.
