I signed my half of the home to my boys in77,ex have died and the wife and other child wants it all...do my boys have any rights there?we built in 74.

The answer will depend on how the property was titled with your wife, either by tenants by the entirety, joint tenants with rights of survivorship, or tenants in common.  Depending on how it was titled, you may not have been able to sign your rights in it over to your sons.  You really need to have an experienced real estate attorney review your deeds and a title search will most likely need to be done. This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.
