Code Civ. Proc., § 663a

(a) A party intending to make a motion to set aside and vacate a judgment, as described in Section 663, shall file with the clerk and serve upon the adverse party a notice of his or her intention, designating the grounds upon which the motion will be made, and specifying the particulars in which the legal basis for the decision is not consistent with or supported by the facts, or in which the judgment or decree is not consistent with the special verdict, either:

(1) After the decision is rendered and before the entry of judgment.

(2) Within 15 days of the date of mailing of notice of entry of judgment by the clerk of the court pursuant to Section 664.5, or service upon him or her by any party of written notice of entry of judgment, or within 180 days after the entry of judgment, whichever is earliest.

(b) Except as otherwise provided in Section 12a, the power of the court to rule on a motion to set aside and vacate a judgment shall expire 75 days from the mailing of notice of entry of judgment by the clerk of the court pursuant to Section 664.5, or 75 days after service upon the moving party by any party of written notice of entry of the judgment, whichever is earlier, or if that notice has not been given, 75 days after the filing of the first notice of intention to move to set aside and vacate the judgment. If that motion is not determined within the 75-day period, or within that period as extended, the effect shall be a denial of the motion without further order of the court. A motion to set aside and vacate a judgment is not determined within the meaning of this section until an order ruling on the motion is entered in the permanent minutes of the court, or signed by the judge and filed with the clerk. The entry of an order to set aside and vacate the judgment in the permanent minutes of the court shall constitute a determination of the motion even though that minute order, as entered, expressly directs that a written order be prepared, signed, and filed. The minute entry shall, in all cases, show the date on which the order is entered in the permanent minutes, but failure to comply with this direction shall not impair the validity or effectiveness of the order.

(c) The provisions of Section 1013 extending the time for exercising a right or doing an act where service is by mail shall not apply to extend the times specified in paragraphs (1) and (2) of subdivision (a).

(d) The moving, opposing, and reply briefs and any accompanying documents shall be filed and served within the periods specified by Section 659a and the hearing on the motion shall be set in the same manner as the hearing on a motion for new trial under Section 660.

(e) An order of the court granting a motion may be reviewed on appeal in the same manner as a special order made after final judgment.
