Cal. Code Civ. Proc. § 473.1
The court may, upon such terms as may be just, relieve a party from a judgment, order, or other proceeding taken against him or her, including dismissal of an action pursuant to Section 581 or Chapter 1.5 (commencing with Section 583.110) of Title 8, where a court of this state has assumed jurisdiction, pursuant to Section 6180 or 6190 of the Business and Professions Code, over the law practice of the attorney for the party and the judgment, order or other proceeding was taken against the party after the application for the court to assume jurisdiction over the practice was filed. Application for this relief shall be made within a reasonable period of time, in no case exceeding six months, after the court takes jurisdiction over the practice. However, in the case of a judgment, order, or other proceeding determining the ownership or right to possession of real or personal property, without extending the six-month period, when a notice in writing is personally served within the state both upon the party against whom the judgment, order, or other proceeding has been taken, and upon the attorney appointed pursuant to Section 6180.5 of the Business and Professions Code to act under the court's direction, notifying the party and the appointed attorney that the order, judgment, or other proceeding was taken against him or her and that any rights the party has to apply for relief under the provisions of the section shall expire 90 days after service of notice, then application for relief must be made within 90 days after service of the notice upon the defaulting party or the attorney appointed to act under the court's direction pursuant to Section 6180.5 of the Business and Professions Code, whichever service is later. No affidavit or declaration of merits shall be required of the moving party.
