My mother recently passed away. My father is the executor and beneficiary of her will.

They have had very little income. Just CPP/OAS and Dad's small pension.

They have no savings.
Mom and Dad have a loan, as co-borrowers.
Dad has a credit card.
Mom also has a credit card.
Both cards are at their credit limit and both are solely in one person's name.
There is also a huge bill for funeral expenses.

Mom's estate has a whopping $300 in the bank account. What happens to her credit card debt? Funeral debt? Is Dad going to be on the hook for all that debt?
