If husband and wife are on deed of house and husband dies but states wife lives in house until she dies then house will go to his kids....can house be sold by wife before her death or can she make out?

In this scenario, the wife's rights depend on the specific terms of the deed and state laws regarding property ownership and inheritance. If the husband has granted her a life estate, she can live in the house until her death, but her ability to sell the house may be limited, as the underlying ownership may pass to his children upon her death. She might need the consent of the children or a legal agreement to sell the house. It's advisable for her to consult with a real estate attorney to clarify her rights and options.
