California Code, Code of Civil Procedure - CCP § 724.050

(a) If a money judgment has been satisfied, the judgment debtor, the owner of real or personal property subject to a judgment lien created under the judgment, or a person having a security interest in or a lien on personal property subject to a judgment lien created under the judgment may serve personally or by mail on the judgment creditor a demand in writing that the judgment creditor do one or both of the following:

(b) The demand shall include the following statement: “Important warning. If this judgment has been satisfied, the law requires that you comply with this demand not later than 15 days after you receive it. If a court proceeding is necessary to compel you to comply with this demand, you will be required to pay my reasonable attorney's fees in the proceeding if the court determines that the judgment has been satisfied and that you failed to comply with the demand. In addition, if the court determines that you failed without just cause to comply with this demand within the 15 days allowed, you will be liable for all damages I sustain by reason of such failure and will also forfeit one hundred dollars to me.”

(c) If the judgment has been satisfied, the judgment creditor shall comply with the demand not later than 15 days after actual receipt of the demand.

(d) If the judgment creditor does not comply with the demand within the time allowed, the person making the demand may apply to the court on noticed motion for an order requiring the judgment creditor to comply with the demand. The notice of motion shall be served on the judgment creditor. Service shall be made personally or by mail. If the court determines that the judgment has been satisfied and that the judgment creditor has not complied with the demand, the court shall either (1) order the judgment creditor to comply with the demand or (2) order the court clerk to enter satisfaction of the judgment.

(e) If the judgment has been satisfied and the judgment creditor fails without just cause to comply with the demand within the time allowed, the judgment creditor is liable to the person who made the demand for all damages sustained by reason of such failure and shall also forfeit one hundred dollars ($100) to such person. Liability under this subdivision may be determined in the proceedings on the motion pursuant to subdivision (d) or in an action.
