My mother died 2 1/2 yrs ago with no estate. She owned a home. We had a joint checking account. I did not notify her credit card company of her death because I was afraid they would take my money out of our joint checking account. Instead I have been paying her bill. The credit card company was informed of my mothers death and wants me to settle her account. They will now be know she died 2 1/2 yrs ago. What will happen?
