403.040.  
(a) The plaintiff, cross-complainant, or petitioner may file a motion for reclassification within the time allowed for that party to amend the initial pleading. The defendant or cross-defendant may file a motion for reclassification within the time allowed for that party to respond to the initial pleading. The court, on its own motion, may reclassify a case at any time. A motion for reclassification does not extend the moving party’s time to amend or answer or otherwise respond. The court shall grant the motion and enter an order for
 reclassification, regardless of any fault or lack of fault, if the case has been classified in an incorrect jurisdictional classification.
(b) If a party files a motion for reclassification after the time for that party to amend that party’s initial pleading or to respond to a complaint, cross-complaint, or other initial pleading, the court shall grant the motion and enter an order for reclassification only if both of the following conditions are satisfied:
(1) The case is incorrectly classified.
(2) The moving party shows good cause for not seeking reclassification earlier.
(c) If the court grants a motion for reclassification, the payment of the reclassification fee shall be determined, unless the court orders otherwise, as follows:
(1) If a case is reclassified as an unlimited civil case, the party whose pleading causes the action or proceeding to exceed the maximum amount in controversy for a limited civil case or otherwise fails to satisfy the requirements of a limited civil case under Section 85 shall pay the reclassification fee provided in Section 403.060.
(2) If a case is reclassified as a limited civil case, no reclassification fee is required.
(d) If the court grants an order for reclassification of an action or proceeding pursuant to this section, the reclassification shall proceed as follows:
(1) If the required reclassification fee is paid pursuant to Section 403.060 or no reclassification fee is required, the clerk shall promptly reclassify the case.
(2) An action that has been reclassified pursuant to this section shall not be further prosecuted in any court until the required reclassification fee is paid. If the required reclassification fee has not been paid within five days after service of notice of the order for reclassification, any party interested in the case, regardless of whether that party is named in the complaint, may pay the fee, and the clerk shall promptly reclassify the case as if the fee had been paid as provided in Section 403.060. The fee shall then be a proper item of costs of the party paying it, recoverable if that party prevails in the action or proceeding. Otherwise, the fee shall be offset against and deducted from the amount, if any, awarded to the party responsible for the fee, if that party prevails in the action or proceeding.
(3) If the fee is not paid within 30 days after service of notice of an
 order of reclassification, the court on its own motion or the motion of any party may order the case to proceed as a limited civil case, dismiss the action or cross-action without prejudice on the condition that no other action or proceeding on the same matters may be commenced in any other court until the reclassification fee is paid, or take such other action as the court may deem appropriate.
(e) Nothing in this section shall be construed to require the superior court to reclassify an action or proceeding because the judgment to be rendered, as determined at the trial or hearing, is one that might have been rendered in a limited civil case.
(f) In any case where the misclassification is due solely to an excess in the amount of the demand, the excess may be remitted and the action may continue as a limited civil case.
