California is a non-judicial forclosure state, meaning the banks may forclose without a court proceeding. If they do that then no remaining amt. owed is collected. However, there are a couple of areas that you may have exposure. If the home has the origional loan or loans that were used to purchase the home then no exposure if you refinanced the origional loan and have seconds in a refinance you may have exposure. Therefore, you would need to check with an attorney if you refinanced the home.
