California Codes, Code of Civil Procedure - CCP, Part 2 — Of Civil Actions, Title 6.5 — Attachment, Chapter 11 — Attaching Plaintiff’s Miscellaneous Remedies, Article 3 — Lien in Pending Action or Proceeding, Section 491.470

(a) If a lien is created under this article, the defendant may claim that all or any portion of the money or property that the defendant may recover in the action or special proceeding is exempt from attachment. The claim shall be made by application on noticed motion to the court in which the action or special proceeding is pending, filed, and served on the plaintiff not later than 30 days after the defendant has notice of the creation of lien. The defendant shall execute an affidavit in support of the application that includes the matters set forth in subdivision (c) of Section 484.070. No notice of opposition to the claim of exemption is required. The failure of the defendant to make a claim of exemption under this section constitutes a waiver of the exemption.

(b) The court may determine the exemption claim at any time prior to the entry of judgment in the action or special proceeding or may consolidate the exemption hearing with the hearing on a motion pursuant to Section 491.460.

(c) If the defendant establishes to the satisfaction of the court that the money or property that the defendant may recover in the action or special proceeding is all or partially exempt from attachment, the court shall order the termination of the lien created under this article on the exempt portion of the money or property.
