My sister's exhusband has custody of their three children. He has since remarried but has not paid her her part of the equity on their house, nor has her name been removed from the mortgage. He died last week and we are wondering if his life insurance will be used to pay off the mortgage on the house. Does the house now belong to my sister? Who is responsible for making payments on the house now? Does his wife and her children have to move out? My sister is going to try to get custody of her kids. This is a huge mess! What are my sister's rights?
