California Code, Code of Civil Procedure - CCP § 706.075

(a) This section applies to any withholding order for taxes issued under this article.

(b) Together with the withholding order for taxes, the state shall serve upon the employer an additional copy of the order and a notice informing the taxpayer of the effect of the order and of his right to hearings and remedies provided in this chapter.  Within 10 days from the date of service, the employer shall deliver to the taxpayer a copy of the order and the notice, except that immediate delivery shall be made where a jeopardy withholding order for taxes has been served.  If the taxpayer is no longer employed by the employer and the employer does not owe the taxpayer any earnings, the employer is not required to make such delivery.

(c) The state shall provide for an administrative hearing to reconsider or modify the amount to be withheld pursuant to the withholding order for taxes, and the taxpayer may request such a hearing at any time after service of the order.  If the taxpayer requests a hearing, the hearing shall be provided, and the matter shall be determined, within 15 days after the request is received by the state.  The determination of the amount to be withheld is subject to the standard provided in subdivision (b) of Section 706.051.  Judicial review of the determination made pursuant to this subdivision by the state may be had only if a petition for a writ of mandate pursuant to Section 1094.5 is filed within 90 days from the date that written notice of the state's determination was delivered or mailed to the taxpayer.

(d) The employer is not subject to any civil liability for failure to comply with subdivision (b).  Nothing in this subdivision limits the power of a court to hold the employer in contempt of court for failure to comply with subdivision (b).
