Will your heir be responsible for foreclosure?

In general, heirs are not personally responsible for a deceased person's debts, including foreclosure, unless they co-signed the mortgage or are otherwise legally obligated. The property itself may go through foreclosure if mortgage payments are not maintained, but the heir can choose to either accept or reject the property during probate. If they reject it, they won't be responsible for the mortgage debt. However, local laws can vary, so it's advisable to consult with a legal professional for specific situations.
