California Community Property: How Marital Assets and Debts Get Divided

"California is a community-property state" is the sentence I say most often at intake, and it is also the sentence that opens the most follow-up questions. What is community. What is separate. What happens to the house we bought before we married but have been paying off together. What about the retirement account. What about the credit card debt in his name.

This post is a plain-language walk through California community-property rules for divorce. It is descriptive, not legal advice for your specific case — characterization is often fact-heavy and small details change the analysis.

The general rule

Under Family Code section 760, everything acquired by either spouse during the marriage is presumed to be community property. That includes wages, salary, retirement contributions, real estate purchased with marital income, business interests built during the marriage, and everyday household assets. Community property is divided equally between the spouses at divorce.

Property that is not community is separate. Under Family Code section 770, separate property is anything a spouse owned before marriage, anything received during marriage by gift or inheritance, and the rents, issues, and profits of separate property. Separate property stays with the spouse who owns it.

The date of separation matters. Property acquired after the date of separation from earnings or accumulations of either spouse is that spouse's separate property. Which is why the date of separation is often litigated when the numbers are large — a bonus paid three months after separation for work performed six months before separation is community, but a bonus paid three months after separation for work performed two months after separation is separate.

Community property in practice

In a typical San Diego divorce, the community-property inventory includes:

• Real estate purchased during the marriage from marital income
• Bank and brokerage accounts funded during the marriage
• Retirement accounts (401(k), IRA, pension) to the extent contributions were made during the marriage
• Vehicles, furniture, jewelry, and household goods acquired during marriage
• Business interests to the extent value was built during marriage
• Stock options and RSUs (vesting analysis matters — the Marriage of Hug and Marriage of Nelson time rules divide these depending on grant and vesting dates)
• Debts incurred during the marriage for community purposes

Separate property in practice

Separate property, by contrast, generally includes:

• Real estate a spouse owned before marriage (subject to reimbursement rules if community funds paid it down — more below)
• Bank accounts a spouse had before marriage, if they can be traced and were not commingled beyond recognition
• Retirement account balances that predate the marriage
• Inheritances and gifts, whether received before or during the marriage
• Personal injury settlements (with some California-specific rules that split economic and non-economic damages)
• Debts incurred by a spouse before marriage or for separate purposes

Hybrid assets: where cases actually get argued

The straightforward cases divide themselves. What takes time, and is usually where an attorney adds real value, is the hybrid asset — an asset that has both community and separate components mixed together.

The house bought before marriage

One of the most common hybrid assets is a house one spouse bought before marriage that both spouses paid off during the marriage. Under a line of California cases going back to Marriage of Moore and clarified in Marriage of Marsden, the community gets a pro-rata share of the appreciation attributable to community payments on the mortgage principal. The Moore/Marsden calculation traces the amount of community principal reduction, applies it to the appreciation during marriage, and gives the community a proportional interest. It is arithmetic-heavy, and it is where I frequently bring in a forensic accountant when the numbers matter.

The retirement account with a pre-marital balance

A 401(k) or IRA with contributions both before and during the marriage is divided using a "time rule" (for defined-benefit pensions) or a direct tracing (for defined-contribution accounts). The pre-marital balance and its earnings stay separate; the marital contributions and their earnings are community. A Qualified Domestic Relations Order (QDRO) is usually needed to divide qualified retirement accounts without triggering tax and penalty.

The business started before marriage and grown during it

A business one spouse owned before marriage but grew during the marriage requires a Van Camp or Pereira analysis (from California cases of the same name). Van Camp values the spouse's services at reasonable market compensation and treats the rest of the growth as return on separate capital. Pereira applies a reasonable rate of return to the separate capital and treats the excess as community. Which framework applies depends on where the business's growth actually came from.

Reimbursements under Family Code section 2640

California has a specific statute, Family Code section 2640, that lets a spouse recover their separate-property contributions to community property. A common example: one spouse used separate savings as a down payment on a house titled jointly during the marriage. At divorce, that spouse can claim a 2640 reimbursement for the down payment (without interest, and capped at the value of the property) before the community equity is divided. 2640 rights can be waived only in a written signed statement, and courts read that requirement strictly.

How debt gets divided

Debt follows similar characterization rules. Debt incurred during marriage is presumed to be community, and is divided equally at divorce. Debt incurred before marriage is separate. Debt incurred during marriage for a spouse's non-community purpose (a girlfriend's rent, a personal legal problem) can sometimes be characterized as separate under Family Code sections 2621 through 2627. The court can allocate community debt to one spouse if the other spouse assumes a corresponding community asset, so the net division stays equal.

What happens after characterization

Once assets and debts have been characterized, the court (or the parties in a settlement) has to divide them equally in value. California does not require every single asset to be split down the middle — the equal division applies to the net community estate. One spouse can take the house and refinance out the community interest; the other spouse can take the retirement account and other liquid assets of equivalent value. What matters is that the numbers balance.

Where to go from here

California community property looks simple in the general principle and complicated in the specific fact. Most contested divorces I handle in San Diego have at least one hybrid asset, and often the difference of tens of thousands of dollars turns on a tracing analysis that has to be done carefully.
