Fam. Code, § 17530

(a) Notwithstanding any other law, this section applies to any actions taken to enforce a judgment or order for support entered as a result of action filed by the local child support agency pursuant to Section 17400, 17402, or 17404, where it is alleged that the enforcement actions have been taken in error against a person who is not the support obligor named in the judgment or order.

(b) A person claiming that a support enforcement action has been taken against that person, or the person’s wages or assets, in error, shall file a claim of mistaken identity with the local child support agency. The claim shall include verifiable information or documentation to establish that the person against whom the enforcement actions have been taken is not the person named in the support order or judgment. The local child support agency shall resolve a claim of mistaken identity submitted pursuant to this section in the same manner and timeframes provided for resolution of a complaint pursuant to Section 17800.

(c) If the local child support agency determines that a claim filed pursuant to this section is meritorious, or if the court enters an order pursuant to Section 17433, the agency shall immediately take the steps necessary to terminate all enforcement activities with respect to the claimant, to return to the claimant any assets seized, to terminate any levying activities or attachment or assignment orders, to release any license renewal or application being withheld pursuant to Section 17520, to return any sums paid by the claimant pursuant to the judgment or order, including sums paid to any federal, state, or local government, but excluding sums paid directly to the support obligee, and to ensure that all other enforcement agencies and entities cease further actions against the claimant. With respect to a claim filed under this section, the local child support agency shall also provide the claimant with a statement certifying that the claimant is not the support obligor named in the support order or judgment, which statement shall be prima facie evidence of the claimant’s identity in any subsequent enforcement proceedings or actions with respect to that support order or judgment.

(d) If the local child support agency rejects a claim pursuant to this section, or if the agency, after finding a claim to be meritorious, fails to take any of the remedial steps provided in subdivision (c), the claimant may file an action with the superior court to establish the mistaken identity or to obtain the remedies described in subdivision (c), or both.

(e) Filing a false claim pursuant to this section shall be a misdemeanor.
