(a) If one party fails to serve on the other party a preliminary declaration of disclosure under Section 2104, unless that party is not required to serve a preliminary declaration of disclosure pursuant to Section 2110, or a final declaration of disclosure under Section 2105, or fails to provide the information required in the respective declarations with sufficient particularity, and if the other party has served the respective declaration of disclosure on the noncomplying party, the complying party may, within a reasonable time,
request preparation of the appropriate declaration of disclosure or further particularity.
(b) If the noncomplying party fails to comply with a request under subdivision (a), the complying party may do one or more of the following:
(1) File a motion to compel a further response.
(2) File a motion for an order preventing the noncomplying party from presenting evidence on issues that should have been covered in the declaration of disclosure.
(3) File a motion showing good cause for the court to grant the complying party’s voluntary waiver of receipt of the noncomplying party’s preliminary declaration of disclosure pursuant to Section 2104 or final declaration of disclosure pursuant to Section 2105. The voluntary waiver does not affect the rights
enumerated in subdivision (d).
(c) If a party fails to comply with any provision of this chapter, the court shall, in addition to any other remedy provided by law, impose money sanctions against the noncomplying party. Sanctions shall be in an amount sufficient to deter repetition of the conduct or comparable conduct, and shall include reasonable attorney’s fees, costs incurred, or both, unless the court finds that the noncomplying party acted with substantial justification or that other circumstances make the imposition of the sanction unjust.
(d) Except as otherwise provided in this subdivision, if a court enters a judgment when the parties have failed to comply with all disclosure requirements of this chapter, the court shall set aside the judgment. The failure to comply with the disclosure requirements does not constitute harmless error. If the court granted the complying
party’s voluntary waiver of receipt of the noncomplying party’s preliminary declaration of disclosure pursuant to paragraph (3) of subdivision (b), the court shall set aside the judgment only at the request of the complying party, unless the motion to set aside the judgment is based on one of the following:
(1) Actual fraud if the defrauded party was kept in ignorance or in some other manner was fraudulently prevented from fully participating in the proceeding.
(2) Perjury, as defined in Section 118 of the Penal Code, in the preliminary or final declaration of disclosure, in the waiver of the final declaration of disclosure, or in the current income and expense statement.
(e) Upon the motion to set aside judgment, the court may order the parties to provide the preliminary and final declarations of disclosure that
were exchanged between them. Absent a court order to the contrary, the disclosure declarations shall not be filed with the court and shall be returned to the parties.
