I think you used a wrong term. Up here usually a living will is used to describe what life saving procedures can be used. If certain life extending procedures are allowed or not.
If he was left the house in a will that means he got the deed. If he now owns house and has the deed with his name on it no one else can sell the house.
If he was willed a portion of a house depending on just how the will is written maybe it could be a forced sale.
Are you talking a life estate? That is where one person owns a house but another has the right to live in the house until they die.... more
