Court Applies Agreement in Property Division
Adrian and Alexandra signed a written ante-nuptial agreement two weeks before their wedding that classified all future business equity as separate property. After divorce proceedings began in a court lacking jurisdiction over some assets from a prior decree, the court reviewed the agreement while apportioning the couple's holdings. The agreement controlled the classification of the equity despite later joint use of proceeds.
Nonmarital Contract Distinguished from Ante-Nuptial Agreement
Austin and Anita lived together without marrying and pooled earnings under an oral understanding. When their relationship ended, Austin sought enforcement of the pooling arrangement as an implied contract. The court refused because the agreement rested inseparably on the provision of sexual services rather than an independent ante-nuptial promise.
Marvin v. Marvin557 P.2d 106 (Cal. 1976)
In October 1964, plaintiff and defendant entered into an oral agreement. While the parties lived together, they would combine their efforts and earnings. They would share equally any and all property accumulated as a result of their efforts, whether individual or combined.
They further agreed to hold themselves out to the general public as husband and wife. Plaintiff would render her services as a companion, homemaker, housekeeper, and cook to defendant. Shortly thereafter, plaintiff agreed to give up her lucrative career as an entertainer and singer. She did so to devote her full time to defendant as a companion, homemaker, housekeeper, and cook. In return, defendant agreed to provide for all of plaintiff's financial support and needs for the rest of her life.
The parties lived together from October 1964 through May 1970. During this period, as a result of their efforts and earnings, they acquired in defendant's name substantial real and personal property. This included motion picture rights worth over $1 million. In May 1970, defendant compelled plaintiff to leave his household. He continued to support plaintiff until November 1971 but thereafter refused to provide further support.
Plaintiff brought this action asserting two causes of action. The first, for declaratory relief, asked the court to determine her contract and property rights. The second sought to impose a constructive trust upon one half of the property acquired during the course of the relationship. Defendant answered the complaint after an unsuccessful demurrer. Following extensive discovery and pretrial proceedings, the case came to trial.
When the case was called for trial, plaintiff sought leave to file an amended complaint. The trial court treated defendant's motion to dismiss as one for judgment on the pleadings. This was augmented by a stipulation that defendant's marriage to Betty Marvin did not terminate until the filing of a final decree of divorce in January 1967. The court granted the motion and entered judgment for defendant. Plaintiff moved to set aside the judgment. She asked leave to amend her complaint to allege that she and defendant reaffirmed their agreement after the divorce became final. The trial court denied the motion. Plaintiff appealed from the judgment.
Preembryo Disposition Agreement Enforced
Aisha and Austin executed an ante-nuptial agreement addressing the disposition of frozen preembryos created during their marriage. After divorce, Aisha sought to use the preembryos over Austin's objection. The court declined to enforce the agreement against the contemporaneous wishes of one donor because it would compel parenthood.
A.Z. v. B.Z.431 Mass. 150, 725 N.E.2d 1051 (2000)
A.Z. and B.Z. married in 1977. For the first two years they resided in Virginia, where both served in the armed forces. They underwent fertility testing after difficulties conceiving. The wife suffered an ectopic pregnancy that resulted in miscarriage and removal of her left fallopian tube.
In 1980 the couple moved to Maryland for a year of additional fertility treatment that produced no pregnancy. The wife transferred to Massachusetts in 1988 while the husband remained in Maryland for schooling. He joined her in Massachusetts in 1991. After arriving in Massachusetts the wife began IVF treatments at a clinic.
The couple first attempted a GIFT procedure on November 6, 1988, which produced another ectopic pregnancy and removal of the wife's remaining fallopian tube. They then pursued IVF from 1988 through 1991. Each time before egg retrieval the couple signed a clinic consent form. They executed seven such forms in total, the last in August 1991. On every form the wife wrote that the preembryos should be returned to her for implantation should the couple separate. The husband usually signed the forms while blank and before the wife completed the disposition language. The 1991 treatment produced twin daughters born in 1992, and two vials of preembryos were frozen for possible later use.
In spring 1995, before the couple separated, the wife thawed one vial and had a preembryo implanted without informing the husband. He learned of the procedure from an insurance notice. Relations deteriorated, the wife obtained a protective order against the husband, the couple separated, and the husband filed for divorce. At the time of divorce one vial containing four frozen preembryos remained in storage. The husband moved for a permanent injunction prohibiting the wife from using the preembryos.
The Probate and Family Court bifurcated the preembryos issue from the divorce action and held a hearing at which both parties were represented by counsel. The probate judge found the consent form unenforceable because of changed circumstances since 1991 and balanced the parties' interests, granting the husband a permanent injunction. The Supreme Judicial Court transferred the case on its own motion. On February 8, 2000, it issued an order affirming the Probate and Family Court judgment, with this opinion to follow.

Students Frequently Ask...
Does an ante-nuptial agreement require consideration to be enforceable?
No. A written ante-nuptial agreement signed by the surviving spouse waiving elective share and allowance rights is enforceable without consideration. The statute treats these agreements as a deliberate departure from ordinary contract rules because they modify preexisting statutory rights rather than create new exchange-based obligations.
Supporting sources
Can spouses alter default property classifications through an ante-nuptial agreement?
Yes. A marital property agreement may vary the effect of default classification rules. The agreement controls the status of equity grants, stock options, and royalties even if the parties later deposit proceeds into a joint account, provided no formal written modification occurs.
Supporting sources
When is an ante-nuptial agreement unenforceable on public policy grounds?
An ante-nuptial agreement is unenforceable if it tends unreasonably to encourage divorce or alters an essential incident of marriage in a way detrimental to the public interest. A promise to pay a large sum upon divorce may be invalid, while an agreement fixing alimony after the marriage has already disintegrated is more likely to be upheld.
Supporting sources
How does a court treat an ante-nuptial agreement when dividing property after a prior decree lacked jurisdiction?
The court must consider the ante-nuptial agreement among other statutory factors when equitably apportioning property. Homemaker contributions, duration of the marriage, and the opportunity for future asset acquisition are weighed alongside the agreement's terms to reach a just division.
