You know if this is something that just occurred then that is bad. She would have no legal right to sell the stuff. If it has been a year or so and there has been no contact well, I would say no problem. But I would try to contact him and see what he has to say. He may not want the stuff any longer, then you are free to get rid of it. Of course he may want it back and for your effort to contact him he may share some of it with you.
