A couple has been married for 11 years and his name is on the deed and sole owner. What happens to the property if he dies with will.?

The property becomes part of his estate upon his death, and will flow through the estate process. The key fact here is that he is the sole owner of the property. When they married, she should have insisted that the deed be rewritten as a joint tenancy with right of survivorship, which would have given her the house upon his death. You can't do this after the person's dead.
