Cal. Family Code - FAM § 2580. Section 2580.
The Legislature hereby finds and declares as follows:
(a)
It is the public policy of this state to provide uniformly and consistently for the standard of proof in establishing the character of property acquired by spouses during marriage in joint title form, and for the allocation of community and separate interests in that property between the spouses.
(b)
The methods provided by case and statutory law have not resulted in consistency in the treatment of spouses’ interests in property they hold in joint title, but rather, have created confusion as to which law applies to property at a particular point in time, depending on the form of title, and, as a result, spouses cannot have reliable expectations as to the characterization of their property and the allocation of the interests therein, and attorneys cannot reliably advise their clients regarding applicable law.
(c)
Therefore, a compelling state
interest exists to provide for uniform treatment of property. Thus, former Sections 4800.1 and 4800.2 of the Civil Code, as operative on January 1, 1987, and as continued in Sections 2581 and 2640 of this code, apply to all property held in joint title regardless of the date of acquisition of the property or the date of any agreement affecting the character of the property, and those sections apply in all proceedings commenced on or after January 1, 1984. However, those sections do not apply to property settlement agreements executed before January 1, 1987, or proceedings in which judgments were rendered before January 1, 1987, regardless of whether those judgments have become final.
