Code Civ. Proc., § 687.020

(a) As used in this section, “instrument” means a check, draft, money order, or other order for the withdrawal of money from a financial institution, the United States, any state, or any public entity within any state.

(b) If an instrument is payable to the judgment debtor on demand and comes into the possession of a levying officer pursuant to this title, the levying officer shall promptly endorse and present the instrument for payment.

(c) The levying officer shall endorse the instrument by writing on the instrument (1) the name of the judgment debtor, (2) the name and official title of the levying officer, (3) the title of the court where the judgment is entered, and (4) the date of entry of the judgment and where entered in the records of the court. The endorsement is as valid as if the instrument were endorsed by the judgment debtor. No financial institution or public entity on which the instrument is drawn is liable to any person for payment of the instrument to the levying officer rather than to the judgment debtor by reason of the endorsement. No levying officer is liable by reason of endorsing, presenting, and obtaining payment of the instrument.

(d) If it appears from the face of the instrument that it has been tendered to the judgment debtor in satisfaction of a claim or demand and that endorsement of the instrument is considered a release and satisfaction by the judgment debtor of the claim or demand, the levying officer shall not endorse the instrument unless the judgment debtor has first endorsed it to the levying officer. If the judgment debtor does not endorse the instrument to the levying officer, the levying officer shall hold the instrument for 30 days and is not liable to the judgment debtor or to any other person for delay in presenting it for payment. At the end of the 30-day holding period, the levying officer shall return the instrument to the maker.
