Upon marrying did his Wife acquire 50% interest in the home in Kentucky?
In addition if this was the homestead it may be exempt from execution by creditors of the estate under Kentucky Exemptions. See http://www.lrc.ky.gov/statutes/statute.aspx?id=18540
Claims can also be compromised with the Creditors if agreement can be made.
396.145 Compromise of claim.
When a claim against the estate has been presented in any manner, the personal
representative may, if it appears for the best interest of the estate, compromise the claim,
whether matured or unmatured, absolute or contingent, liquidated or unliquidated.
