§ 2825 Surety Liability Principal Discharge

• •If someone promises to pay your debt (like a friend or a company), they can't just say 'nope' if you get out of paying because of some rule or law.
• •The person you owe money to (like a bank) doesn't have to do anything wrong for this to happen.
• •The promise to pay your debt still stands, even if you legally don't have to pay anymore.

Your friend promises the bank they'll pay your car loan if you can't. Later, a new law says you don't have to pay the loan anymore.

Even though you don't have to pay the loan because of the new law, your friend still has to pay the bank if they promised to.
