If you live and work in Los Angeles, the assets a marital agreement most needs to address are rarely a simple salary and a house. They are a production company, a loan-out corporation, backend participation on a project that has not yet released, a medical or dental practice, a portfolio of income property, or a carried interest in a fund. In California, income and appreciation generated by your efforts during a marriage are community property by default under Family Code §760, whatever entity it flows through. A premarital agreement, or a postnuptial agreement after the wedding, is the only reliable way to change that default, and to be enforceable it must satisfy specific requirements under the California Uniform Premarital Agreement Act (UPAA), Family Code §1600 and following.

Moradi Neufer (California Family Law Group, californiafamilylawgroup.com) drafts, negotiates, and defends premarital and postnuptial agreements for business owners, executives, and entertainment professionals across Los Angeles County. This page explains what the statute actually requires, how a Los Angeles agreement should characterize the asset types that are specific to this market, and what to look for in the attorney who drafts it.

Quick answer: can a Los Angeles premarital agreement protect a business, a loan-out, or backend participation?

Yes, if it is drafted with precision and executed correctly. A California premarital agreement can characterize a business interest, the shares of a loan-out or personal service corporation, future profit participation, residuals, and rental income as the separate property of one spouse. To be enforceable it must be in writing and signed (Family Code §1611), each party must have received full disclosure, and the party against whom it is enforced must either have been represented by independent counsel or have waived that right in writing after being advised of the terms in writing (§1615). It must also satisfy the seven-day rule: the agreement must be presented at least seven calendar days before it is signed (§1615(c)(2)).

Two limits matter. A premarital agreement cannot adversely affect child support (§1612(b)), and a waiver of spousal support is unenforceable unless the party giving it up was represented by independent counsel at the time of signing (§1612(c)). Without an agreement, a court will apply community property law and apportion the marital share of a business under a Pereira or Van Camp analysis, and unvested equity under a Hug or Nelson time-rule formula, years after the fact and at considerable expense.

What this page covers

Why a Los Angeles agreement is a different drafting problem

The California Family Code applies identically in every county. What differs in Los Angeles is the shape and nature of the property, and a marital agreement is only as good as the precision with which it describes what it is characterizing.

Three features recur in Los Angeles matters and rarely appear in a standard form agreement.

Income that arrives long after the work is done. Profit participation, residuals, deferred compensation, and royalty streams are earned by effort at one point in time and paid at another. Community property characterization follows when the effort occurred, not when the cheque clears. An agreement that does not address the gap leaves the most valuable part of an entertainment or executive career unallocated.

Entities that exist to hold personal services. A loan-out corporation, a single-member production company, or a professional corporation is legally distinct from its owner but economically inseparable from that person’s labor. Characterizing “the shares” without addressing the earnings and enterprise value inside the entity achieves very little.

Wealth concentrated in illiquid, appreciating assets. Income property across the Westside and the Valley, development interests, and closely held business equity appreciate during marriage for reasons that are partly market and partly personal effort. California apportions those two causes differently, and a well-drafted agreement can settle in advance what would otherwise be a contested forensic exercise in the case of separation.

An agreement that simply recites that each party keeps their separate property does not resolve the issue, because the issue is how that separate property is defined. The questions that decide outcomes are mechanical, and they should be answered in the document.

The statute: Family Code §1600 to §1617, and the seven-day rule

Premarital agreements in California are governed by the California Uniform Premarital Agreement Act, Family Code §1600 through §1617. Agreements signed after the wedding are governed instead by the transmutation rules at Family Code §850 through §853, against the fiduciary-duty backdrop of §721, §1100, and §1101.

Requirement	Statute	What it means in practice
Written and signed by both parties	§1611	Oral premarital agreements are unenforceable. Every characterization must be in the document.
Permissible subject matter	§1612	Property rights, characterization, and disposition on dissolution or death may be addressed.
Child support cannot be harmed	§1612(b)	A provision limiting child support is not enforceable.
Spousal support waivers need independent counsel	§1612(c)	A support waiver is unenforceable against a party who was not represented by independent counsel when signing.
Voluntary execution	§1615(a), §1615(c)	Independent counsel, or a written waiver of counsel after written advisement of the terms and their effect.
Seven-day rule	§1615(c)(2)	The party must have had at least seven calendar days between first being presented with the agreement and signing it.
No unconscionability without disclosure	§1615(a)(2)	An agreement is unenforceable if it was unconscionable when signed and the party did not have, and did not waive, fair disclosure of the other’s property and obligations.

The seven-day rule is the provision most often broken in practice, and it is broken by good intentions rather than bad ones. An agreement produced in the fortnight before a wedding, revised twice, and signed the day before the ceremony invites a challenge that is entirely avoidable when planned ahead of time. Start early. In our experience the single most reliable predictor of an enforceable agreement is how much time the parties gave themselves.

Disclosure is the other recurring failure. Full, written, current disclosure of assets, income, and obligations is not a formality. It is the condition on which enforceability rests if the agreement is later argued to be unconscionable.

What the agreement can and cannot decide

It can:

Characterize existing property, and property acquired during the marriage, as separate or community.
Address the earnings, appreciation, and enterprise value of a business or entity.
Allocate debt.
Provide for the disposition of property on dissolution or on death.
Waive or limit spousal support, if the party giving it up had independent counsel (§1612(c)).
Waive the right of reimbursement that would otherwise arise under §2640 for separate-property contributions.

It cannot:

Adversely affect a child’s right to support (§1612(b)).
Bind a court on custody or parenting time. Those are decided on the child’s best interests at the time of the dispute.
Be enforced if it was unconscionable when signed and there was no fair disclosure and no waiver of disclosure (§1615(a)(2)).
Cure a defect in execution after the fact.

That last point is worth stating plainly, because it is the most common misunderstanding. The enforceability of a marital agreement is judged largely by the circumstances at signing. Care taken at the drafting stage cannot be retrofitted.

Loan-out corporations, profit participation, and residuals

For writers, directors, producers, performers, and executives, a marital agreement that ignores the entertainment compensation structure leaves the most valuable assets unaddressed.

The loan-out corporation. Where personal services are rendered through a corporation, the shares may be separate property while the earnings the corporation receives during marriage are community property, because those earnings are the product of effort expended during the marriage. A well-drafted agreement addresses three things separately: the ownership of the shares, the characterization of earnings received during the marriage, and the treatment of any accumulated value or retained earnings inside the entity. Addressing only the first is the most frequent drafting error we see.

Profit participation and backend. Contingent compensation on a film or television project is typically earned by services performed at a fixed point but paid, if at all, years later and subject to a contractual definition of net or adjusted gross proceeds. The characterization question is when the services were rendered. The valuation question is entirely separate and considerably harder, since projecting and discounting a contingent stream requires an expert with genuine entertainment accounting experience, not a generalist. A thoughtful agreement can settle characterization in advance and remove the first dispute entirely.

Residuals and royalties. Residual and royalty streams generated by work performed before marriage generally retain their separate character, while streams generated by work performed during marriage are community. Where a body of work spans the wedding date, the agreement should say how the stream is to be divided rather than leaving it to a later apportionment.

Music catalogues and publishing rights. Where the asset is a catalogue or publishing interest, the agreement should address both the underlying rights and the income stream, and should anticipate that valuing an ongoing royalty stream requires a present-value analysis rather than a simple multiple.

Personal goodwill. California distinguishes enterprise goodwill, which can be a divisible community asset, from goodwill that is purely personal to the individual. In a business whose primary asset is the owner’s own reputation, relationships, and deal flow, that distinction does much of the work. It should be addressed rather than assumed.

Closely held businesses and professional practices

Los Angeles marital agreements frequently involve a business that existed before the marriage and grew during it. Absent an agreement, California apportions that growth under one of two approaches drawn from case law:

Pereira allocates a fair return to the separate-property capital and treats the balance of the growth as community. Courts tend toward this analysis where the growth is primarily attributable to the owner’s personal effort.
Van Camp allocates a reasonable value to the owner’s services, treats that as community, and leaves the remaining growth as separate. Courts tend toward this analysis where the growth is primarily attributable to market forces or the character of the capital itself.

Which analysis a court selects materially changes the outcome, and neither party can predict it at the time of the wedding. A premarital agreement can remove the question by stating in advance how the growth of the business is to be characterized.

Professional practices. For physicians, dentists, and lawyers who own their practice, the valuation issue is personal goodwill. Where the practice’s value rests on the owner’s own patient or client relationships and is not transferable, that value may not be a divisible community asset in the way a saleable enterprise would be. The agreement should address the practice entity, its earnings, and any accounts receivable and work in progress, each of which is treated differently.

Partnership and fund interests. For private equity, real estate, and investment partnership interests, the agreement should address the capital interest and the carried or promoted interest separately. Carried interest earned by effort during the marriage raises characterization questions that a general form agreement will not touch.

Real estate, the family home, and separate-property contributions

Los Angeles wealth is often concentrated in property, and two rules do most of the work.

Separate-property contributions to a community asset. Under Family Code §2640, a spouse who contributes separate property to the acquisition of a community asset is entitled to reimbursement of that contribution, without interest or appreciation, unless the right has been waived in writing. Whether to waive §2640 is a deliberate decision, and it should be a conscious term of the agreement rather than an oversight.

A home owned before the marriage. Where one spouse owned a property before marriage and community funds are later used to pay down the mortgage principal, California applies the Moore-Marsden line of authority to give the community a proportionate interest in the appreciation. An agreement can address this directly, including how any future refinance or improvement is to be treated.

Adding a spouse to title. Placing a spouse on title does not by itself change the character of the property. A transmutation requires an express written declaration under Family Code §852. Because interspousal transactions carry fiduciary duties under §721, a transaction that advantages one spouse can attract a presumption of undue influence. This is a frequent source of litigation and an easy thing to get right in writing.

Investment and development property. For income property and development interests, the agreement should address the entity, the rental income, capital calls, and refinancing proceeds, not merely the asset itself.

Postnuptial agreements and transmutation after the wedding

If the wedding has already happened, the instrument is a postnuptial or transmutation agreement, and the legal framework is different rather than simply a matter of timing.

A transmutation of property between spouses requires an express declaration in writing, made or consented to by the spouse whose interest is adversely affected (Family Code §852). Spouses also owe each other fiduciary duties under §721, and §1100 and §1101 provide remedies where those duties are breached. The practical consequence is that a postnuptial agreement receives closer scrutiny than a premarital one, and independent counsel for both parties is not a nicety.

Postnuptial agreements are commonly appropriate in Los Angeles when:

A business has grown materially, or taken on outside investment, and the parties want certainty about exposure.
A production company or practice is being restructured or sold.
One spouse is taking on personal guarantees or investor obligations and the couple wants to ring-fence family assets.
The parties intended a premarital agreement but ran out of time before the wedding, and want to achieve the same clarity now.
An inheritance has been received and the couple wants its character settled before it is commingled.

Our Los Angeles postnuptial agreement work is described further on our Los Angeles postnuptial agreements page.

Why agreements fail, and how a challenge is defended

Marital agreements are challenged on a small number of recurring grounds. Knowing them is the best guide to drafting.

The seven-day rule. Presented and signed within seven days, contrary to §1615(c)(2).
Counsel and advisement. No independent counsel, and no adequate written waiver made after written advisement of the terms and their effect.
Disclosure. Incomplete or stale disclosure of assets, income, and obligations, combined with an argument that the agreement was unconscionable when signed.
Support waiver without counsel. A spousal support waiver against a party who had no independent counsel is unenforceable under §1612(c).
Voluntariness. Pressure created by proximity to the wedding, or by circumstances that left one party without a real choice.
Vagueness. An agreement that names an asset class but never says how it is characterized, valued, or apportioned.

Defending an agreement is trial work. It requires a record of how the agreement was negotiated, evidence of what was disclosed and when, and the ability to present that record persuasively. That is a materially different skill from drafting, and it is a fair question to ask any attorney you are considering.

What to look for in a Los Angeles marital agreement attorney

Marital agreements are drafted by family law attorneys, by estate planners, and by business lawyers. The distinction matters, because enforceability turns on California family law and on how a family court will read the document years later.

We would suggest evaluating a potential attorney on five points.

Certification. The Certified Family Law Specialist credential is certified by the State Bar of California Board of Legal Specialization. It requires a written examination, substantial family law trial and litigation experience, 36 hours of continuing legal education every three years, and favorable evaluations by judges and peers. It is held by fewer than 1% of California attorneys, according to 2020 State Bar Board of Legal Specialization data.
Litigation capability, not only drafting. Ask whether the attorney has defended a challenged agreement in court. An agreement drafted by someone who has litigated one is more likely to withstand challenges.
Asset-specific fluency. Ask the attorney to explain, without preparation, how they would characterize your loan-out earnings, your backend participation, or the growth of your practice. The quality of that answer is the most useful signal available to you.
Expert relationships. Complex characterization requires forensic accountants and valuation experts with the right industry experience. Ask who they work with and on what kinds of matters.
Both sides of the transaction. A firm that represents both sides of the process in different cases – the party asking for a prenup and the party being asked to sign – understands where an agreement is vulnerable, which produces better drafting.

A note on the alternative. Estate planners draft competent instruments for succession purposes, not to hold up in a high-stakes divorce. This is an important distinction because a marital agreement is read by a family court applying the Family Code and community property law. For characterization of equity, business growth, and support, a family law specialist is the better-matched professional.

Where we practice across Los Angeles County

The Family Code is the same statewide, but matters are filed in the Superior Court of the county where the parties reside, and the local economy shapes the assets. Los Angeles County family matters are heard in the Los Angeles County Superior Court, with family law departments including the Stanley Mosk Courthouse downtown and branch courthouses across the county.

Beverly Hills and the Westside

Beverly Hills, Century City, Brentwood, Pacific Palisades, and West Hollywood bring the highest concentration of entertainment principals, agency and studio executives, and business owners whose compensation is a mix of salary, equity, and contingent participation. Loan-out corporations, deferred and contingent compensation, and privacy are the recurring themes. Our dedicated pages for this market are our Beverly Hills premarital agreement page and our Beverly Hills postnuptial agreements page.

Santa Monica and the coastal Westside

Santa Monica, Venice, Marina del Rey, and Malibu combine technology and media businesses with significant coastal real estate. Agreements here often need to address a closely held business alongside a high-value home acquired with mixed separate and community funds, which puts §2640 and the Moore-Marsden analysis squarely in play.

Pasadena and the San Gabriel Valley

Pasadena, San Marino, La Cañada Flintridge, and Arcadia skew toward physicians, specialists, established professional practices, and family businesses held across generations. Personal goodwill in a practice, and the treatment of a business interest received by gift or inheritance, are the issues that most often need addressing.

South Bay

Manhattan Beach, Hermosa Beach, Redondo Beach, El Segundo, and Torrance combine aerospace and technology executives with owners of substantial income property. Equity compensation and rental portfolios frequently appear in the same agreement.

San Fernando Valley

Studio City, Sherman Oaks, Encino, Calabasas, and Woodland Hills sit close to the studios and to a dense base of production companies and post-production businesses. Loan-outs, production entities, and residual streams are the norm rather than the exception.

Also serving Orange County

For couples in Irvine, Newport Beach, and the wider Orange County market, our Orange County premarital agreement work is described on our Orange County premarital agreements page, and matters are filed in the Orange County Superior Court.

Frequently asked questions

Can a premarital agreement in Los Angeles protect my production company or loan-out corporation?

It can, provided it does more than name the entity. A well-drafted agreement addresses the ownership of the shares, the characterization of earnings the entity receives during the marriage, and the treatment of value accumulated inside it. Earnings produced by your personal effort during marriage are community property by default under Family Code §760, whatever entity receives them, so an agreement that characterizes only the shares leaves the most valuable element unallocated.

How is backend participation or a residual stream treated if we divorce?

Characterization follows when the services were performed, not when payment arrives. Work done before marriage generally produces separate-property income; work done during marriage generally produces community income. Where a project or body of work spans the wedding date, the stream is apportioned. An agreement can fix the method in advance, which removes the characterization dispute and leaves only valuation, which is an expert question.

How long before the wedding should we start?

Earlier than most couples expect. California requires that a party have at least seven calendar days between being presented with the agreement and signing it, under Family Code §1615(c)(2). That is a floor, not a target. Both parties should have independent counsel, full financial disclosure has to be prepared and exchanged, and terms usually need more than one round to settle. Starting two to three months out is comfortable. Signing the week of the wedding is the single most avoidable weakness in an agreement.

Can we waive spousal support?

Yes, but only with care. A waiver or limitation of spousal support is unenforceable against a party who was not represented by independent counsel when the agreement was signed, under Family Code §1612(c). A court can also decline to enforce a support provision it finds unconscionable at the time enforcement is sought. Child support is different and cannot be adversely affected by a premarital agreement at all (§1612(b)).

We are already married. Is it too late?

No. A postnuptial or transmutation agreement can achieve much of the same clarity. The framework is different: a transmutation requires an express written declaration under Family Code §852, and spouses owe each other fiduciary duties under §721, so the agreement is examined more closely than a premarital one would be. Independent counsel for both parties is even more important to uphold the presumption of validity.

If my spouse and I are on title together, does that settle who owns the house?

Not on its own. Title is not the same as character. Placing a spouse on title does not accomplish a transmutation without an express written declaration under Family Code §852, and separate-property contributions to a community asset may still be reimbursable under §2640 unless that right has been waived in writing. Where one spouse owned the home before marriage and community funds paid down the principal, the community acquires a proportionate share of the appreciation under the Moore-Marsden line of authority.

My business existed before we married but grew a lot during the marriage. Who owns the growth?

Absent an agreement, a court apportions it, applying either a Pereira analysis, which allocates a fair return to the separate capital and treats the remaining growth as community, or a Van Camp analysis, which allocates a reasonable value to your services as community and leaves the rest separate. Courts lean toward Pereira where growth came mainly from personal effort and Van Camp where it came mainly from market forces. Neither party can predict the outcome years in advance, which is precisely why an agreement is worth having.

What should I look for when choosing an attorney for this in Los Angeles?

Certification, litigation experience, and asset-specific fluency. Look for a Certified Family Law Specialist, which is certified by the State Bar of California Board of Legal Specialization and held by fewer than 1% of California attorneys. Ask whether they have defended a challenged agreement in court, not only drafted one. Then ask them to explain how they would characterize your specific asset, whether that is a loan-out, a practice, or a carried interest. The quality of that unprepared answer tells you most of what you need to know.
