§ 2819 Surety Exoneration By Creditor

• •If someone promises to pay your debt (like a friend helping you with a loan), they don’t have to pay if the person you owe money to changes the deal without asking them first.
• •The helper (surety) is off the hook if the lender makes it harder to get the money back from you (the borrower).
• •This rule doesn’t override another law (Section 2822(b)) that might say something different.

Your friend agrees to pay your car loan if you can’t. Later, the bank lets you skip payments for 6 months without telling your friend.

Your friend doesn’t have to pay the loan anymore because the bank changed the deal without asking them.
