Just got home and found a message on the answering machine someone named mark looking for my sister in law, said he found our number in the white pages.

Now knowing michelle and also knowing she's just moved and hasn't paid anything on her car loan this year I'm 99% sure its a debt collector.

My problem is if I don't tell them the details I know can it come back to bite me on the bum? If for some reason she was taken to court over it something? I'm honestly more inclined to tell them because she needs a bloody wake up call but if I don't is that ok? And if I don't and they keep calling what are my rights?

Thanks for any help you might be able to give.

We're also the only one in my husbands family (very unique last name, only ones in the country lol) listed and this has happened before.
