What are adult childrens rights to house if mom dies and was remarried?

When a mother who has remarried passes away, the rights of her adult children to her house depend on several factors, including whether the house was solely owned by her, if it was part of a marital property, and the terms of her will or estate plan. If the house was owned solely by the mother and she did not designate it to her new spouse or others in her will, adult children may inherit it. However, if the house was jointly owned or if there are provisions in her will favoring her spouse, the rights of the adult children could be limited. It's essential for them to consult with an estate attorney to understand their specific rights and options.
