I am sorry for your loss. Unfortunately I would say most likely you do not have a claim to the house. I say this because it is very likely the house was held in joint tenancy between your dad and his wife. The house was his to give away to his wife. He likely did this through joint tenancy or maybe she went to court and got a spousal property order or other order!? In any event, assuming the house became hers it was then hers to give away when she died. I thus suspect you are out of luck here. Best of luck. -John
