What will happen if a wife dies without a will then the husband dies a few years later and wills the home to his adult grandson without anyone contesting it?

Answer 1

The estate of each party should be examined in chronological order of death. The wife's estate would be distributed according to the laws of intestacy where she resided. If the deed of the home was in someone else's name, then that would also complicate it (e.g., tenants in common with husband's siblings, having inherited from grandpa...). If father's estate doesn't include the home, then any provisions about it in his will are irrelevant. If the deed or the intestate succession of the wife put the title into the hands of the children and not the surviving spouse, then the grandson has no present claim.
