Widows & Widowers Support Group
This community is dedicated to those who have lost a husband, wife, or partner. Anything is open for discussion here, with the hope that we can focus on grief, bereavement, life after loss, and continuing on after a great loss.

As far as your husband's credit card debt, you may not owe it or anything on his medical bills. It depends on which State you live in. You may owe if you live in a community property state.
You will need to get some advice on this from either your State or local office for the elderly/senior citizens - it goes by different names depending on your State or locale. If you have a local senior center, they may have volunteers that can guide you or at least refer you to the correct agency to find out. Your doctor's office or the funeral home may also have helpful telephone numbers to sort out these questions.
Most places in the USA have free or reduced fee legal advice to senior citizens through the local or State bar associations. You would only need a brief consultation to answer your basic questions. You can look in the phone book or online to find your local bar association.
Don't panic and don't give up. It may not be anywhere as bad as you think it is.
Love and Hugs,
Martha
