So, holy fucking hell:
"We’ve received complaints that private student loan servicers are placing borrowers into default when their co-signer dies or files for bankruptcy."
So basically, if a loved one co-signed on your student loan and subsequently dies or has to declare bankruptcy, the lender can then turn around and demand the balance for literally no other reason. Your mom dies, and you’ve been late precisely zero times? Fuck you, they want all their money now. Your dad has to declare bankruptcy because of medical bills? Fuck you, they’re sending your loan into default.
Because there’s nothing illegal about pulling this shit, their recommendation is:
"If you are a co-signer or have a student loan with a co-signer and you are in repayment, you should look into what’s called “co-signer release.” You should consider this option to avoid a surprise default. Both the borrower and co-signer can benefit from obtaining the release."
