Prenups and Spousal Support

What a Prenuptial Agreement Can Say About Spousal Support

Family Code section 1610(a) defines a premarital agreement as "an agreement between prospective spouses made in contemplation of marriage and to be effective upon marriage." It is the formal name for a prenup. Under section 1611 it must be in writing and signed by both parties, and under section 1613 it takes effect only when the marriage happens.

The rules come from California's Uniform Premarital Agreement Act, Family Code sections 1600 through 1617. Family Code section 1612 lists what the parties may contract about: property rights, management of property, what happens to property on separation, divorce or death, the choice of governing law, and "any other matter, including their personal rights and obligations, not in violation of public policy or a statute imposing a criminal penalty." Subdivision (c) then speaks directly to "any provision in a premarital agreement regarding spousal support, including, but not limited to, a waiver of it." In other words, the Act expects that couples will write about support, and sets special conditions when they do.

Spousal support and property division often appear in the same document, but they are different subjects. Property terms decide who owns what. Support terms decide whether one spouse pays the other going forward, and for how long. Without an agreement, a judge sets support by weighing a long list of factors in Family Code section 4320, including the marital standard of living, each party's earning capacity, the length of the marriage, age and health, and the goal that the supported party become self-supporting within a reasonable time. A support clause in a prenup is an attempt to settle that question in advance, and the law tests it differently from the property terms.

Where it is tested matters too. When a prenup is raised in a San Diego County divorce, the case is heard in the Superior Court of California, County of San Diego, in the division the court's ZIP Code List (ADM-254) assigns. The four family law divisions are the Central Division at the Central Courthouse, 1100 Union Street, San Diego, CA 92101; the North County Division at the North County Regional Center, 325 South Melrose Drive, Vista, CA 92081; the East County Division at the East County Regional Center, 250 East Main Street, El Cajon, CA 92020; and the South County Division at the South County Regional Center, 500 3rd Avenue, Chula Vista, CA 91910. The court publishes the ZIP Code List.

The Independent-Counsel Requirement Under Family Code § 1612(c)

The statute's language is short and worth reading in full. Family Code section 1612(c) says a spousal-support provision, including a waiver,

"is not enforceable if the party against whom enforcement of the spousal support provision is sought was not represented by independent counsel at the time the agreement containing the provision was signed, or if the provision regarding spousal support is unconscionable at the time of enforcement."

"Independent counsel" means a lawyer who represents only that person. The other partner's attorney does not count, even if that attorney is friendly, explains the document patiently, or offers to answer questions. The "party against whom enforcement is sought" is usually the spouse who would have received support but for the clause.

This first condition is measured at one moment: the day the agreement was signed. Either the person had their own lawyer then, or they did not. Notice also what the statute does not offer. Section 1612(c) has no option to sign a separate waiver of counsel for the support clause. The final sentence adds a further point: an otherwise unenforceable support provision "may not become enforceable solely because the party against whom enforcement is sought was represented by independent counsel." Having a lawyer is necessary for the clause, but it does not cure every other problem.

The second condition, unconscionability, is a different test at a different time, and it has its own section below. It is also separate from the general requirements for the whole agreement in section 1615, which carry their own rules about counsel and timing.

When a Spousal-Support Provision Is Tested: Enforcement, Not Signing

A spousal-support clause is often signed in a season of optimism and read for the first time in earnest during a divorce. That gap is exactly what section 1612(c) addresses. Its test has two parts:

1. Was the party against whom the clause is enforced represented by independent counsel when the agreement was signed?
2. Is the provision unconscionable at the time of enforcement?

If the answer to the first is no, or the answer to the second is yes, the support provision is not enforceable. Either ground alone is enough.

"Unconscionable" means so one-sided or harsh that a court will not enforce it. The phrase "at the time of enforcement" is what makes the spousal-support rule unusual. The court looks at the parties' lives as they are when someone asks to enforce the clause, usually at the divorce, not only as they were at the wedding. A marriage can last decades. Careers rise and stall, children arrive, health changes. A waiver that looked balanced between two working professionals may be examined in a very different light many years later.

This page describes the standard, not how any judge will apply it. Whether a particular clause crosses the line depends on the facts presented when enforcement is sought, and no outcome is assured either way. Family Code section 1617 also notes that statutes of limitation for claims under a premarital agreement are tolled during the marriage, though equitable defenses such as laches and estoppel remain available.

How Family Code § 1615 Applies to the Whole Agreement

Family Code section 1615 sets the conditions for the entire premarital agreement, support clause included. Under section 1615(a), the agreement is not enforceable if the challenging party proves either that they did not sign voluntarily, or that the agreement was unconscionable when signed and, before signing, all three of these applied: they did not receive fair, reasonable and full disclosure of the other party's property and financial obligations; they did not voluntarily and expressly waive further disclosure in writing; and they did not have, or reasonably could not have had, adequate knowledge of those finances. Section 1615(b) adds that unconscionability under this section is decided by the court as a matter of law.

Section 1615(c) then defines voluntariness in a demanding way. The agreement is deemed not signed voluntarily unless the court finds, in writing or on the record, all of the following:

• The party had independent counsel at signing, or, after being advised to seek counsel at least seven calendar days before the final agreement was signed, expressly waived counsel in a separate writing.
• For agreements signed on or after January 1, 2020, the party had at least seven calendar days between first being presented with the final agreement and signing it, whether or not they had a lawyer. (A similar seven-day rule applied to agreements signed between January 1, 2002, and January 1, 2020.) Nonsubstantive amendments are excepted.
• An unrepresented party was fully informed, in writing, of the terms, the basic effect and the rights given up, was proficient in the language used, and signed a document confirming who gave that information.
• There was no duress, fraud or undue influence, and both parties had capacity.
• Any other factors the court finds relevant.

Here is the key distinction. Section 1615 lets a party waive independent counsel in a separate writing for the agreement as a whole. Section 1612(c) gives no such option for the spousal-support provision. Both sections can apply to the same document at the same time: an agreement may satisfy section 1615 and still have an unenforceable support clause, while the remaining terms stand or fall on their own.

What 'Waiving' Spousal Support in a Prenup Actually Means

Someone reviewing a draft for the first time often reads the support section several times, because the wording carries real weight. A support provision can take several forms. A complete waiver means each party gives up the right to seek spousal support from the other after a divorce. Other clauses set a cap on the amount, limit the number of years support can run, or use a formula tied to the length of the marriage or to income. Section 1612(c) covers all of these, since it reaches "any provision" regarding spousal support.

The same two tests apply whatever form the clause takes: independent counsel at signing and no unconscionability at enforcement. A waiver is not self-executing in the sense of being beyond review. When one spouse asks a court to apply it, the other spouse can raise section 1612(c), and the court decides.

Absent a valid clause, the court's ordinary rules govern. For marriages of long duration, Family Code section 4336 provides that the court generally retains jurisdiction over support indefinitely, with a presumption that a marriage of 10 years or more, from marriage to separation, is of long duration. That section expressly allows "written agreement of the parties to the contrary," which is one reason support terms are drafted with care.

Child support is a separate matter altogether. Section 1612(b) states that "the right of a child to support may not be adversely affected by a premarital agreement." A spousal-support waiver does nothing to a parent's obligation to support a child.

If a support clause is challenged in a San Diego County divorce, that dispute is decided in the same Superior Court division that hears the rest of the case, determined by ZIP code under ADM-254.

Common Reasons Spousal-Support Provisions Fail in California

The grounds below come straight from the statutes. Each is something a court may consider; none decides a case on its own description here.

No independent counsel at signing. This is the most direct ground under section 1612(c). If the spouse giving up support relied on the other partner's lawyer, or had no lawyer, the support clause is not enforceable against them.

Too little time to review. Under section 1615(c), an agreement signed on or after January 1, 2020, is deemed not voluntary unless the party had at least seven calendar days between first seeing the final agreement and signing it. A document finalized days before the wedding raises this problem for the whole agreement.

Inadequate financial disclosure. Section 1615(a)(2) allows a challenge where the agreement was unconscionable when signed and the party lacked fair, reasonable and full disclosure, did not waive it in writing, and had no adequate independent knowledge of the other's finances.

Unconscionability at enforcement. Changed circumstances over a long marriage are the classic setting: one spouse left paid work to raise children, a serious health problem developed, or a large income gap appeared that did not exist at signing. Section 4320's factors, such as earning capacity and periods out of the workforce for domestic duties, show the kinds of facts a court is used to weighing.

Drafting Considerations for a Spousal-Support Provision

Each party having their own lawyer is the plainest way to meet section 1612(c). Because that section allows no waiver of counsel for the support clause, a draft that relies on one shared attorney leaves the clause exposed from the start.

Timing comes next. Finalizing the agreement well before the wedding, rather than the week of it, addresses the seven-day rule in section 1615 and the broader question of whether anyone felt pressed to sign. Full financial disclosure by both partners, ideally written down and attached, supports enforceability under section 1615(a)(2).

Specific language matters as well. A clause that is vague about whether it is a full waiver, a cap or a time limit can invite a dispute about what it means, on top of whether it is enforceable.

Finally, lives change. Section 1614 provides that after marriage a premarital agreement may be amended or revoked only by a written agreement signed by the parties. Some couples revisit their terms through a postnuptial agreement, which is a marital agreement signed after the wedding. A premarital agreement is signed before marriage; the two are distinct instruments. The Uniform Premarital Agreement Act is written for premarital agreements, and agreements between spouses are subject to other rules, including the fiduciary duty of "the highest good faith and fair dealing" spouses owe each other under Family Code section 721. Family Code section 1500 confirms that statutory property rights may be altered by a premarital agreement or other marital property agreement.
