JULY 22 - 29, 1983


The number of marriages between persons previously married and the number of marriages between persons each of whom is intending to continue to pursue a career is steadily increasing. For these and other reasons, it is becoming more and more common for persons contemplating marriage to seek to resolve by agreement certain issues presented by the forthcoming marriage. However, despite a lengthy legal history for these premarital agreements, there is a substantial uncertainty as to the enforceability of all, or a portion, of the provisions of these agreements and a significant lack of uniformity of treatment of these agreements among the states. The problems caused by this uncertainty and nonuniformity are greatly exacerbated by the mobility of our population. Nevertheless, this uncertainty and nonuniformity seem reflective not so much of basic policy differences between the states but rather a result of spasmodic, reflexive response to varying factual circumstances at different times. Accordingly, uniform legislation conforming to modern social policy which provides both certainty and sufficient flexibility to accommodate different circumstances would appear to be both a significant improvement and a goal realistically capable of achievement.

This Act is intended to be relatively limited in scope. Section 1 defines a "premarital agreement" as "an agreement between prospective spouses made in contemplation of marriage and to be effective upon marriage." Section 2 requires that a premarital agreement be in writing and signed by both parties. Section 4 provides that a premarital agreement becomes effective upon the marriage of the parties. These sections establish significant parameters. That is, the Act does not deal with agreements between persons who live together but who do not contemplate marriage or who do not marry. Nor does the Act provide for postnuptial or separation agreements or with oral agreements.

On the other hand, agreements which are embraced by the act are permitted to deal with a wide variety of matters and Section 3 provides an illustrative list of those matters, including spousal support, which may properly be dealt with in a premarital agreement.

Section 6 is the key operative section of the Act and sets forth the conditions under which a premarital agreement is not enforceable. An agreement is not enforceable if the party against whom enforcement is sought proves that (a) he or she did not execute the agreement voluntarily or that (b) the agreement was unconscionable when it was executed and, before execution of the agreement, he or she (1) was not provided a fair and reasonable disclosure of the property or financial obligations of the other party, (2) did not voluntarily and expressly waive, in writing, any right to disclosure of the property or financial obligations of the other party beyond the disclosure provided, and (3) did not have, or reasonably could not have had, an adequate knowledge of the property and financial obligations of the other party.

Even if these conditions are not proven, if a provision of a premarital agreement modifies or eliminates spousal support, and that modification or elimination would cause a party to be eligible for support under a program of public assistance at the time of separation, marital dissolution, or death, a court is authorized to order the other party to provide support to the extent necessary to avoid that eligibility.

These sections form the heart of the Act; the remaining sections deal with more tangential issues. Section 5 prescribes the manner in which a premarital agreement may be amended or revoked; Section 7 provides for very limited enforcement where a marriage is subsequently determined to be void; and Section 8 tolls any statute of limitations applicable to an action asserting a claim for relief under a premarital agreement during the parties' marriage.


SECTION 1. DEFINITIONS. As used in this Act:

(1) "Premarital agreement" means an agreement between prospective spouses made in contemplation of marriage and to be effective upon marriage.

(2) "Property" means an interest, present or future, legal or equitable, vested or contingent, in real or personal property, including income and earnings.


The definition of "premarital agreement" set forth in subsection (1) is limited to an agreement between prospective spouses made in contemplation of and to be effective upon marriage. Agreements between persons living together but not contemplating marriage (see Marvin v. Marvin, 18 Cal. 3d 660 (1976), judgment after trial modified, 122 Cal. App. 3d 871 (1981)) and postnuptial or separation agreements are outside the scope of this Act. Formal requirements are prescribed by Section 2. An illustrative list of matters which may be included in an agreement is set forth in Section 3.

Subsection (2) is designed to embrace all forms of property and interests therein. These may include rights in a professional license or practice, employee benefit plans, pension and retirement accounts, and so on. The reference to income or earnings includes both income from property and earnings from personal services.
