Thanks for all the responses and your time.
The death occurred in the end of July. The letters Testamentary were dated the end of September. The house was signed over to the person it was left to the end of October.
When the credit card companies called, they were told of her death. A few stated that they were submitting a claim to the estate. I have heard nothing from the court,lawyer or anything else from them. They have just sent letters asking to contact them with the intentions of the estate regarding the debt.
