Who is responsible for paying any bills of your deceased mother?

Hopefully she has left a Will. If she owns a house or property this is called an Estate and this also includes contents of where she lived. Here are two sceneriOS: If your father predeceased your mother and she is left with a house and the property it is on, plus a vehicle, and she has left a Will, then there would be an Executor/Executrix (male/female) named in the Will. If there isn't then it will be put in a Trustee's hands for Probate. Probate is to make sure all taxes are paid on that property and all creditors are paid and this also includes personal income tax. Once that is done (takes about a year) then the Executor/Executrix or Trustee will inform the heirs of the Will and all monies or property will be divided as ordered in the said Will. If your mother was living on a fixed income and she was renting and had no property and few contents such as furnishings, etc., and no Will, then the Credit Card company is out of luck and will have to take their loses. You are not responsible for the Credit Card companie's loss. I am so sorry for your loss. Marcy
