California Code, Family Code - FAM § 2120

(a) The State of California has a strong policy of ensuring the division of community and quasi-community property in the dissolution of a marriage as set forth in Division 7 (commencing with Section 2500), and of providing for fair and sufficient child and spousal support awards. These policy goals can only be implemented with full disclosure of community, quasi-community, and separate assets, liabilities, income, and expenses, as provided in Chapter 9 (commencing with Section 2100), and decisions freely and knowingly made.

(b) It occasionally happens that the division of property or the award of support, whether made as a result of agreement or trial, is inequitable when made due to the nondisclosure or other misconduct of one of the parties.

(c) The public policy of assuring finality of judgments must be balanced against the public interest in ensuring proper division of marital property, in ensuring sufficient support awards, and in deterring misconduct.

(d) The law governing the circumstances under which a judgment can be set aside, after the time for relief under Section 473 of the Code of Civil Procedure has passed, has been the subject of considerable confusion which has led to increased litigation and unpredictable and inconsistent decisions at the trial and appellate levels.
