Will surviving children be responsible for paying deceased parents medical bills?

i just lost my aunt and her children had to pay her medical bills.there are programs that will help the children pay them if they cant. * Many times surviving family members will be sent medical and hospital bills after a person has died. However, the children of the deceased or other family members have no legal obligation to pay such debts unless they have agreed to accept the responsibility at the time the person(s) were receiving medical care. Medical bills as are all other debts and assets are considered part of the deceased's estate and are handled according to the state probate laws.
