Retail Installment SalesPayments
Section § 1806.1
If a buyer pays money toward a contract or installment account, and they don't know that the contract is being or will be assigned to someone else, their obligation to pay is considered fulfilled by that payment, as long as it's made to the last person they know holds the contract.
Section § 1806.2
If you have a contract where payments are recorded in a passbook or payment book, you can ask for a detailed statement showing what you still owe. You can request this once a year for free, but if you need more, it will cost no more than a dollar each time. This must be done within a year of the last payment.
Section § 1806.3
If you have a contract and decide to pay off the money you owe early, you can do so without any penalty. There are rules about what happens to any leftover finance charge, which depends on how it was calculated. If it was calculated based on all interest upfront, you may get a refund for the part you didn't use. If it was calculated on simple interest, you pay what you owe up to that point. Also, if the contract ends early because of things like giving back the item you bought, repossession, or legal judgments, your remaining debt is determined the same way. This rule doesn't stop any other late fees allowed by law from being collected.
Section § 1806.4
Once a buyer has paid off everything they owe on a contract, they can ask to get proof that their debt is fully paid, and any security interest in the goods tied to the contract is released. The holder of this contract has to provide this proof, either by mail or delivery, to the buyer's last known address.
