The Legislature finds and declares the following:
(a) It is the policy of the State of California (1) to marshal, preserve, and protect community and quasi-community assets and liabilities that exist at the date of separation so as to avoid dissipation of the community estate before distribution, (2) to ensure fair and sufficient child and spousal support awards, and (3) to achieve a division of community and quasi-community assets and liabilities on the dissolution or nullity of marriage or legal separation of the parties as provided under California law.
(b) Sound public policy further favors the reduction of the adversarial nature of marital dissolution and the attendant costs by fostering full disclosure and cooperative discovery.
(c) In order to promote this public policy, a full and accurate disclosure of all assets and liabilities in which one or both parties have or may have an interest must be made in the early stages of a proceeding for dissolution of marriage or legal separation of the parties, regardless of the characterization as community or separate, together with a disclosure of all income and expenses of the parties. Moreover, each party has a continuing duty to immediately, fully, and accurately update and augment that disclosure to the extent there have been any material changes so that at the time the parties enter into an agreement for the resolution of any of these issues, or at the time of trial on these issues, each party will have a full and complete knowledge of the relevant underlying facts.
