Due to health problems they are having financial difficulty. They have a bank issued credit card with $24,000 in debt. I've read that the bank can't touch their SS but my question is can they come after other assets like their house which they have a mortgage on or their car which is the only car they have and are still paying on?
And, beyond the car note, a certain amount of value is exempt anyway.
Yes. They can come after their assets such as their house and car, although they would be secondary to the mortgage holder on the house and the note holder on the car.
