§ 2821 Surety Exoneration After Rescission

• •If a deal changes what a borrower owes or makes it harder for the lender to get their money back, and that deal lets a co-signer off the hook, then canceling the deal later doesn’t put the co-signer back on the hook.
• •Once a co-signer is freed from their promise to pay because of a new deal, they stay freed even if the new deal is canceled.
• •This rule protects co-signers from being suddenly responsible again if the original deal changes and then gets canceled.

Imagine you co-sign a loan for your friend to buy a car. Later, the bank makes a new deal with your friend that says you no longer have to pay if your friend misses payments. Even if the bank cancels that new deal later, you still don’t have to pay—you’re off the hook for good.

The law says that once the co-signer (you) is freed from the responsibility because of the new deal, canceling that deal doesn’t make you responsible again.
