Beverly Hills Prenuptial Agreements
A prenuptial agreement is rarely set aside because its terms were unfair. Far more often it fails on process — a disclosure that was incomplete, or a signature collected too close to the wedding to look voluntary.
A prenuptial agreement gives engaged couples a legally enforceable way to define those terms in advance. California holds these agreements to a specific statutory standard, and the timeline matters as much as the substance: an agreement signed too close to the wedding date faces a real risk of being set aside no matter how fair its terms are.
Duncan Family Law represents Beverly Hills clients seeking to have a prenuptial agreement drafted, reviewed, or negotiated by an attorney who understands the standard in detail. Every client works directly with founder Nicole Duncan from the first conversation through the final signature, with no handoff to junior staff at any stage.

— Compliance with the UPAA is everything. California enforces prenups only under the Uniform Premarital Agreement Act (Family Code §§1600–1617); close compliance is what makes them hold.
— The seven-day rule is mandatory. Section 1615 requires at least seven days between presenting the agreement and signing it — a rushed signature is the most common way a prenup fails.
— Full financial disclosure is essential. Each party must fairly disclose assets, debts, and income; an incomplete schedule is a leading ground for a later challenge.
— Independent counsel is strongly recommended. It is required for a spousal-support waiver to hold, and it is the strongest evidence the agreement was signed knowingly and voluntarily.
— A prenup cannot decide child custody or support. Those issues are always reserved for the court under the best-interests standard.
— Business owners should plan before appreciation occurs. Defining a business and its future growth as separate before the wedding avoids a contested Pereira/Van Camp analysis later.
— A prenup is generally easier to enforce than a postnup. It is judged as of the date it was signed, while a postnuptial agreement is held to the stricter interspousal fiduciary standard under §721.

About Attorney Nicole Duncan
The Basics
A prenuptial agreement, also called a premarital agreement, is a written contract between two people who are planning to marry. It takes effect upon marriage and addresses how property, debts, and support will be handled if the marriage ends in divorce, legal separation, or death.
California prenuptial agreements are governed by the Uniform Premarital Agreement Act at Family Code §§1600–1617. Under §1611, the agreement must be in writing and signed by both parties.
No separate payment or exchange is required for it to be valid, and the general authority for spouses to alter their statutory property rights by written agreement traces back to Family Code §1500.
Family Code §1615 requires that the party against whom enforcement is sought have at least seven calendar days between the first presentation of the agreement and the advice to seek independent legal counsel and the date of signing.
Courts treat this seven-day window as a meaningful signal of voluntariness, not a technicality, and agreements rushed through in the final days before a wedding are among the most commonly challenged.
A prenuptial agreement does not have to be adversarial. Most Beverly Hills couples approach it as a practical planning tool, similar to estate planning, that clarifies expectations before the marriage begins rather than a document born out of distrust.

Enforceability
California scrutinizes prenuptial agreements closely, particularly where one spouse has significantly more assets or income than the other. Meeting each of the following requirements is essential — and together they form the checklist a court runs through when an agreement is challenged.
Under Family Code §1611, the agreement must be in writing and signed by both prospective spouses. Oral agreements, however detailed the conversation, are not enforceable.
Each party must provide a fair, reasonable disclosure of their assets, debts, and income before signing. Where full disclosure was not given, the agreement can be challenged, unless the other spouse expressly waived the right to further disclosure in a separate writing.
As described above, §1615 requires a minimum of seven calendar days between the presentation of the agreement and its signing, along with the opportunity to seek independent legal counsel during that period. This requirement exists specifically to prevent last-minute pressure before a wedding date.
Independent representation for each party is not required for every provision, but it is required for a spousal support waiver to be enforceable under Family Code §1612(c). The California Supreme Court’s decision in In re Marriage of Bonds confirmed that a party is not automatically excused from a prenuptial agreement simply for lacking counsel, but courts still treat independent representation as the strongest evidence that an agreement was entered into knowingly and voluntarily.
The agreement must be entered into voluntarily, free of duress, fraud, or undue influence. Most prenuptial agreement provisions are tested for fairness as of the date they were signed, which is a meaningfully different standard than the one California applies to postnuptial agreements signed after the wedding, where fairness is tested at the time enforcement is sought.
Scope
A valid prenuptial agreement in California can address a wide range of financial questions, though it operates within real boundaries set by the Family Code and by public policy, including:
There are firm limits. A prenuptial agreement cannot predetermine child custody or child support, and any term that is unconscionable, illegal, or contrary to public policy will not be enforced.
A Beverly Hills prenuptial agreement attorney can help you understand exactly where those boundaries fall.
Complex Assets
Beverly Hills is dense with business owners, family offices, and multi-generational wealth. A prenuptial agreement is frequently the cleanest way to keep a business, a family trust interest, or an inheritance clearly separate from the marriage from day one.
Protecting Separate Property
A properly disclosed prenuptial agreement can designate a business owned before the marriage, along with its future growth, as separate property. Addressing this before the wedding avoids the far more complicated characterization analysis that applies once a business has already grown during the marriage.
| example · A software company started before the wedding
A Beverly Hills entrepreneur launches a software company two years before getting engaged. Five years into the marriage, the company has grown substantially — and if the marriage ends, the question becomes how much of that growth is community property. Without a prenup, California resolves it through a contested Pereira or Van Camp analysis that can turn on how the founder spent their time. A prenup drafted before the wedding can define the business and its future appreciation as separate property, replacing years of uncertainty with a single agreed rule. |
Many Beverly Hills clients have family wealth held in trusts established by parents or grandparents. A prenuptial agreement can confirm that trust distributions and inherited assets remain separate property, and we routinely coordinate the agreement’s language directly with a client’s estate planning attorney so the documents work together rather than creating ambiguity.
| example · An expected trust distribution
A client expects to become a beneficiary of a family trust established by their parents. Inheritances and gifts are generally separate property under California law — but distributions can lose that character once they are deposited into joint accounts or spent on community purposes. A prenup can confirm that trust distributions and inherited assets stay separate, and, coordinated with the family’s estate plan, keep the two documents from contradicting each other later. |
Equity compensation is one of the most commonly mischaracterized assets in a California divorce, because awards granted before the wedding often vest — and are partly earned — during the marriage. A prenuptial agreement can set the rule in advance rather than leaving it to a vesting-schedule fight later.
Industry Income
Beverly Hills clients frequently include a spouse whose income comes from entertainment work: acting, producing, directing, or representing those who do. A prenuptial agreement can resolve the characterization questions that income raises well before any dispute arises.
Royalties and residuals from prior work. Income from work created before the marriage, including ongoing royalties and residuals, is generally separate property, but a prenuptial agreement can state that explicitly, so there is no later argument about whether marital funds or effort were used to maintain or exploit that work during the marriage.Future projects and backend participation. A prenuptial agreement can define in advance how income from future projects, including backend participation and deferred compensation negotiated before the wedding, will be treated if the marriage ends.
Property Division
Beverly Hills marriages frequently involve a primary residence with substantial equity, vacation properties, closely held businesses, and concentrated investment positions. Without a prenuptial agreement, California’s community property rules determine how assets acquired during the marriage are divided, and the line between separate and community property can blur as accounts are commingled and separate funds are used toward jointly titled property. See our property division practice for the complete legal framework.
A prenuptial agreement lets a couple define those rules in advance, before any assets have commingled or grown in value, which is generally the clearest and least contested way to protect separate property over the life of a marriage.
Pitfalls
Even couples who agree completely on the terms can end up with an unenforceable agreement if the process itself has gaps. The mistakes we see most often include:
Step by Step
A prenuptial agreement is built in stages, and the biggest risk to enforceability is almost always timing. The process at Duncan Family Law generally follows the path below — with the mandatory seven-day review period built in, not squeezed in at the end.
From engagement to effect — the seven-day window is the step couples most often run out of time for.
Prenup vs. Postnup
Couples who are already married sometimes ask whether it is too late for an agreement like this. It is not, though the instrument changes.
A prenuptial agreement is signed before the wedding and is generally tested for fairness as of the date it was signed. A postnuptial agreement addresses the same subject matter after the wedding, but California’s interspousal fiduciary duty under Family Code §721 applies once the marriage exists, which makes postnuptial agreements harder to enforce than prenups signed in advance.
Couples who are engaged are always better positioned if they have a prenuptial agreement completed well before the wedding date.
| Prenuptial | Postnuptial |
| Signed before the wedding | Signed after the wedding |
| Fairness tested as of the date it was signed | Fairness tested when enforcement is sought |
| Governed by the UPAA (Family Code §§1600–1617) | Governed by the interspousal fiduciary duty (§721) |
| Generally easier to enforce | Held to a stricter standard |
| A planning tool used before marriage | Used to adjust terms during the marriage |
For couples who are already married, our postnuptial agreement page explains how that process works.
Local Realities
Beverly Hills is a small city by area and population, but a significant one for prenuptial planning. The concentration of business owners, entertainment professionals, and multi-generational family wealth here means that even a straightforward engagement can involve assets and income structures that require careful, specific drafting.
The median single-family home value in the 90210 ZIP code routinely exceeds $4 million, meaning a primary residence alone can represent a significant share of one party’s premarital net worth. Family trusts, closely held businesses, and entertainment industry income are common enough in Beverly Hills households that they show up in prenuptial agreements far more often than in most other parts of the country.
Duncan Family Law approaches every Beverly Hills prenuptial agreement with those local realities as the starting point, not an afterthought.
The Difference
Get Started
The most useful first step toward a prenuptial agreement is a direct, confidential conversation about your specific situation: your assets, your timeline, and what a realistic agreement looks like under California law.
The earlier that conversation happens, the more room there is to build an agreement that will actually hold — because the disclosure and the seven-day review that protect it both take time.

Yes, if it meets California’s requirements under the Uniform Premarital Agreement Act, including a written, signed agreement, full financial disclosure, the seven-day review period, and voluntary execution. Working with Nicole Duncan at Duncan Family Law from the start significantly improves an agreement’s odds of holding up.
As early as possible. Family Code §1615 requires at least seven calendar days between being presented with the agreement and advised to seek independent counsel and the date of signing. Signing too close to the wedding date is one of the most common reasons a prenuptial agreement is later challenged.
California does not require independent counsel for every provision, but a spousal support waiver is not enforceable unless the waiving party had independent legal counsel at signing. Independent representation on both sides is strongly recommended for the entire agreement, not just the support terms.
Yes. A prenuptial agreement can waive or limit spousal support, provided the party against whom the waiver is enforced was represented by independent counsel at signing and the provision is not unconscionable at the time enforcement is sought.
The agreement must be voluntary, so pressure or last-minute ultimatums undermine its enforceability. Starting the conversation early, providing full financial disclosure, and allowing time for independent review typically resolves reluctance far better than urgency does.
Yes. A properly disclosed prenuptial agreement can designate a business owned before the marriage, along with its future growth, as separate property, which is one of the most common reasons Beverly Hills business owners pursue one.
Income from work created before the marriage is generally separate property, but a prenuptial agreement can state that clearly and define how income from future projects will be treated, thereby removing significant uncertainty in any later dispute.
Yes. A prenuptial agreement can confirm that trust distributions and inherited assets remain separate property, and can be coordinated directly with an existing family trust or estate plan so the documents are consistent with each other.
A prenuptial agreement itself can be amended or revoked by written agreement of both spouses after the marriage, but such an amendment is evaluated under the same fiduciary duty standard that governs postnuptial agreements, not the standard that applied when the original prenuptial agreement was signed.
A useful starting set includes recent tax returns, statements for bank, brokerage, and retirement accounts, a summary of any business interests or equity compensation, real estate and mortgage records, and information about any trust or inheritance interests. Digital copies are sufficient for the initial consultation, and Duncan Family Law will tell you exactly what is needed once we understand your specific situation.
A straightforward agreement can often be completed in a few weeks, provided there is enough time before the wedding to satisfy the seven-day review period. Agreements involving business valuations or complex real estate take longer. Duncan Family Law guides clients through the process efficiently at every stage.
