Cal. Civ. Code § 1812.2
In the event of any default by the buyer in the performance of his obligations under a contract or installment account, the holder, pursuant to any rights granted therein, may proceed to recover judgment for the balance due without retaking the goods, or he may retake the goods and proceed as hereinafter provided. If he retakes the goods, he shall, within 10 days, give notice to the buyer of his intention to sell the goods at public sale or give notice to the buyer of his intention to retain the goods in satisfaction of the balance due. The notice must state the amount of the overdue payments, that the buyer must pay, if he pays within 10 days of the notice, in order to redeem the goods. In either case the buyer shall have an absolute right to redeem the goods within 10 days after the notice is given by paying or tendering the amount owing under the contract. If the holder gives notice of election to sell the goods the buyer shall also have the absolute right to redeem the goods at any time before sale by paying or tendering the amounts specified above and also any expense reasonably incurred by the seller or holder in good faith in repairing, reconditioning the goods or preparing them for sale. If the holder gives notice of his intention to retain the goods in satisfaction of the indebtedness he shall be deemed to have done so at the end of the 10-day period if the goods are not redeemed; at the time the notice is given, the holder shall furnish the buyer a written statement of the sum due under the contract and the expenses provided for in this section. For failure to render such a statement the holder shall forfeit to the buyer ten dollars ($10) and also be liable to him for all damages suffered because of such failure.
