Code Civ. Proc., § 704.110

(a) As used in this section:

(1) “Public entity” means the state, or a city, city and county, county, or other political subdivision of the state, or a public trust, public corporation, or public board, or the governing body of any of them, but does not include the United States except where expressly so provided.

(2) “Public retirement benefit” means a pension or an annuity, or a retirement, disability, death, or other benefit, paid or payable by a public retirement system.

(3) “Public retirement system” means a system established pursuant to statute by a public entity for retirement, annuity, or pension purposes or payment of disability or death benefits.

(b) All amounts held, controlled, or in process of distribution by a public entity derived from contributions by the public entity or by an officer or employee of the public entity for public retirement benefit purposes, and all rights and benefits accrued or accruing to any person under a public retirement system, are exempt without making a claim.

(c) Notwithstanding subdivision (b), where an amount described in subdivision (b) becomes payable to a person and is sought to be applied to the satisfaction of a judgment for child, family, or spousal support against that person:

(1) Except as provided in paragraphs (2) and (3), the amount is exempt only to the extent that the court determines under subdivision (c) of Section 703.070.

(2) If the amount sought to be applied to the satisfaction of the judgment is payable periodically, the amount payable is subject to an earnings assignment order for support as defined in Section 706.011, or any other applicable enforcement procedure, but the amount to be withheld pursuant to the assignment order or other procedure shall not exceed the amount permitted to be withheld on an earnings withholding order for support under Section 706.052. The paying entity may deduct from the payment being made to the judgment debtor, for each payment made pursuant to an earnings assignment order under this paragraph, an amount reflecting the actual cost of administration caused by the assignment order of up to two dollars ($2) for each payment.

(3) If the intercept procedure provided for in Section 11357 of the Welfare and Institutions Code is used for benefits that are payable periodically, the amount to be withheld shall not exceed the amount permitted to be withheld on an earnings withholding order for support under Section 706.052.

(4) If the amount sought to be applied to the satisfaction of the judgment is payable as a lump-sum distribution, the amount payable is subject to the intercept procedure provided in Section 11357 of the Welfare and Institutions Code or any other applicable enforcement procedure.

(d) All amounts received by any person, a resident of the state, as a public retirement benefit or as a return of contributions and interest thereon from the United States or a public entity or from a public retirement system are exempt.
