Dividing a Business or Professional Practice in an Orange County Divorce

A business built during marriage, or grown substantially while a couple was together, does not automatically belong to the spouse whose name is on the door. Under California’s community property system, any increase in value attributable to marital effort or funds is subject to division, and the court’s first task is to determine how much belongs to the community rather than to the owner alone. The answer comes down to three questions: what the business is worth, how much of that worth was created during the marriage, and whether the non-owner spouse will be bought out, receive other assets in exchange, or remain a co-owner.

This is one of the more financially significant issues an Orange County divorce can raise, and the numbers explain why. California is home to roughly 4.3 million small businesses as of 2026, and the average small business owner in the state now earns approximately 126,000 dollars annually. Orange County alone counts more than 76,000 small businesses. When a marriage involves a business or a licensed professional practice such as a medical office, dental practice, or law firm, dividing that asset requires a valuation, a legal framework for separating community and separate interests, and a plan for what happens once the divorce is finalized.

What Happens To a Business in an Orange County Divorce?

California Family Code Section 760 establishes that property acquired during marriage is community property, owned equally by both spouses, unless it qualifies as separate property. A business started before the marriage generally begins as separate property, but growth in its value during the marriage can create a community interest, particularly when tied to one spouse’s labor or reinvested income. A business started during the marriage is typically community property in its entirety, regardless of whose name appears on the formation documents. At Sarieh Family Law, this distinction often becomes the single most contested issue in a divorce involving a closely held company or professional practice.

Business interests commonly appearing in Orange County divorce cases include:

• Sole proprietorships and single-member LLCs
• Medical, dental, legal, or accounting practices built around a licensed professional
• Family-owned businesses with relatives holding informal or formal stakes
• Franchise operations and multi-location retail or service businesses
• Partnerships or corporations where the divorcing spouse holds a percentage interest

Each requires its own valuation approach, and professional practices raise the added complication of goodwill.

How Is Business Goodwill Valued Under Pereira and Van Camp?

Goodwill is the value a business holds beyond its physical assets and bank balance, and California law distinguishes between two categories. Enterprise goodwill attaches to the business itself and is treated as community property subject to division. Personal goodwill attaches to the individual practitioner’s reputation and skill, and generally remains that spouse’s separate interest, since it cannot be transferred or sold along with the business.

When a business existed before the marriage or was built with separate funds but grew in value while the couple was together, California courts apply one of two formulas from Pereira v. Pereira and Van Camp v. Van Camp. Pereira applies when growth was driven mainly by the owner-spouse’s personal effort; the court assigns a fair return on the original investment and treats the remainder as community property. Van Camp applies when growth was driven mainly by the business itself. Here, the court values the owner’s labor, treats it as community property, and lets the remaining growth remain separate.

Consider a real-world pattern common in Orange County practices. A physician opens a private practice five years before marrying, then spends the next decade growing it by adding staff and building a loyal patient base through personal reputation. Because that growth is tied to the physician’s own labor, a court is more likely to apply Pereira, assigning a modest return to the original investment and treating the bulk of the increase as community property to be divided.

Buyout Or Continued Co-Ownership: Which Approach Fits?

Once the community interest in a business is identified and valued, the couple, or the court, must decide how to divide it. There are generally three paths forward:

• Buyout, where the spouse who runs the business keeps it and pays the other their share, often using cash or a structured payment plan
• Offset, where the owner keeps the business, and the other receives other marital property of comparable value
• Continued co-ownership, where both spouses retain an interest and keep operating the business together

Buyouts are the most common outcome, since few former spouses want to stay financially intertwined through a shared company after the marriage ends. Co-ownership is rare and typically only succeeds when the separation is amicable. Offsets work well when the marital estate holds sufficient other assets to offset the business’s value without forcing a sale.

Can a Post-Nuptial or Buy-Sell Agreement Protect a Business?

Business owners who did not sign a prenuptial agreement are not without options. A post-nuptial agreement, signed during the marriage, can define how a business will be treated if the marriage later ends, provided it is entered into voluntarily, in writing, and with full financial disclosure from both spouses. California Family Code Section 721 imposes a fiduciary duty between spouses that applies to these agreements, meaning neither spouse may use superior business knowledge to pressure the other into an unfair deal.

A buy-sell agreement, often drafted at the business formation stage among partners, serves a related but distinct purpose. It can require a divorcing owner to sell their interest back to the company or other partners at a predetermined valuation method, preventing a former spouse from becoming an unwilling business partner. Addressing these documents early, before a marriage shows strain, matters because courts scrutinize agreements signed under pressure or right before a filing far more closely.

How Does Business Income Affect Spousal and Child Support?

Business ownership also shapes ongoing support obligations. California Family Code Section 4320 directs courts to weigh each spouse’s earning capacity and income when ordering spousal support, but self-employment income is not always calculated the same way as an employee’s paycheck. In re Marriage of Blazer, a California appellate court held that a judge may exclude a portion of business income from support calculations when there is a legitimate reason to reinvest those funds in the company.

This discretion cuts both ways. An owner who genuinely reinvests profit into the business may see support calculated on a lower figure, while a spouse who suspects income is being deferred to minimize support can request a forensic review of the finances. Because child support relies on the same income figures, these disputes affect both outcomes at once. The team at Sarieh Family Law regularly works with forensic accountants to make sure a business owner’s true income, not just what appears on a tax return, is presented accurately to the court.

There is no way around the fact that a business built with years of long hours, financial risk, and personal sacrifice can feel inseparable from the person who built it, and watching a court decide how much of it belongs to someone else can be one of the most disorienting parts of a divorce.

That fear is real, and so is the potential for real loss if the process is handled carelessly. But it does not have to end in the business being gutted or lost. With the right valuation, strategy, and advocate to protect what you built, it is entirely possible to walk away from a divorce with your business and future still intact.
