Complex Assets Require Precise Legal Work

What 'High Net Worth Divorce' Means Under California Law

What practitioners usually mean is a case with several asset classes that each need their own analysis. Common examples include a closely held business, brokerage accounts, real property in more than one state, deferred compensation, stock options, restricted stock units (RSUs, which are shares an employer promises once a vesting schedule is met), and defined-benefit pensions (plans that pay a set monthly amount in retirement).

The complexity comes from three tasks: characterization (labeling each asset community or separate), valuation (putting a number on it), and division (deciding who takes what and how the other spouse is paid out). Our broader overview of property division in high-net-worth divorces covers how these steps fit together.

Community Property, Separate Property, and the Lines That Matter

Separate property is defined in Cal. Fam. Code § 770. It includes property owned before marriage, property received during marriage by gift, bequest, devise, or descent (in plain terms, gifts and inheritances), and the rents, issues, and profits of that property. Everything acquired during the marriage that does not fit those categories starts out presumed community under § 760.

Commingling is the mixing of separate and community money in one place. It happens constantly: an inheritance deposited into a joint account, a premarital brokerage account that later receives salary contributions. When funds are mixed, the spouse claiming a separate share has to trace it. Tracing means following the money through records to show where a separate dollar went and what it bought. Without documents, mixed funds tend to be treated as community.

Two accounting methods come up when a separate business grows during marriage. Under the Pereira approach, the separate owner receives a fair return on the original capital, and the rest of the growth is treated as community, because it came from the owner's labor. Under the Van Camp approach, the community receives fair pay for the owner's labor, and the remaining growth stays separate. Courts generally use Pereira when personal effort drove the growth and Van Camp when market conditions or the capital itself did. On a company that tripled in value during the marriage, the choice between them can move millions of dollars.

For a couple with a modest estate, a fight over these lines might be worth a few thousand dollars. For a couple whose wealth sits in a company, a stock grant, or an inherited trust, the same fight can decide the largest number in the case. That is why characterization is so often the most contested issue in San Diego high-asset divorces.

Business Interests and Professional Practices in a San Diego Divorce

A business started or built during the marriage is presumed community property to the extent of the community's contribution. That holds for a biotech startup in Torrey Pines, a dental practice in Chula Vista, a law or medical partnership, or a membership interest in a real estate LLC. If the business started before marriage, the Pereira or Van Camp analysis above decides how much of the growth belongs to the community.

Goodwill is often the hardest piece. Goodwill is the value a business has beyond its equipment, cash, and receivables, the reason customers keep coming back. California distinguishes enterprise goodwill, which belongs to the business itself (its brand, systems, location, and staff), from personal goodwill, which follows a particular person's skill and reputation. Enterprise goodwill is generally a divisible community asset. Personal goodwill is generally not, because it cannot be sold apart from the person. In a professional practice, where the owner is the reason clients come, this distinction can drive the whole valuation.

Equity compensation is common in San Diego County, given the region's defense contractors, life sciences companies, and technology employers. Stock options and RSUs often straddle the date of separation. In In re Marriage of Hug (1984) 154 Cal.App.3d 780, the court approved a time-rule formula for allocating options between community and separate property. In plain terms, the community share is a fraction: the part of the period from grant (or hire, depending on the facts) to vesting that fell during the marriage, divided by the whole period. A grant still unvested at separation can therefore be partly community property even though no shares have been delivered.

Real Estate, Investment Accounts, and Retirement Assets

Real property brings its own formulas. When one spouse buys a home before marriage and community funds later pay down the mortgage, courts apply what is known as the Moore/Marsden calculation. The separate owner keeps a separate interest tied to the down payment and pre-marriage principal reduction. The community earns a share of the appreciation based on the principal it paid. A separate down payment on a home bought during marriage is handled differently. Under Cal. Fam. Code § 2640, a spouse who traces separate funds into community property is generally reimbursed for down payments, improvements, and principal reduction, though not interest, maintenance, insurance, or taxes, and without interest or inflation adjustment. Our guides on real estate in divorce and on vacation homes go further into these calculations.

Investment accounts follow the same characterization rules. Gains on community funds are community. An account opened before marriage, or funded with an inheritance, can keep its separate character, but only if tracing shows which deposits and which growth came from the separate source. Concentrated stock positions, where much of the wealth sits in one company's shares, raise added questions about tax cost and timing when the account is split. The same principles reach accounts held abroad, a subject covered in our article on offshore accounts.

Defined-benefit pensions also use a time rule. The community share is generally the years of service during marriage divided by total years of service, applied to the benefit. Our article on pension plans and retirement benefits explains how that fraction is carried into the order.

Spousal Support in High-Asset San Diego Cases

Long-term support, ordered in the judgment, turns on the factors in Cal. Fam. Code § 4320. They include each party's earning capacity measured against the marital standard of living, the supported spouse's marketable skills and any career gaps taken on for the household, contributions to the other spouse's education or career, the supporting spouse's ability to pay, each party's needs, each party's obligations and assets including separate property, the length of the marriage, the effect of employment on dependent children, age and health, documented domestic violence, and other factors the statute lists.

When income runs well above what guideline software handles meaningfully, courts exercise independent judgment. For readers trying to estimate their own exposure or need, this is often the most uncertain part of the case. Our articles on spousal support in a high-income divorce and on alimony in a high net worth divorce explain how judges approach those numbers.
