California Community Property: A Complete Guide

What Is Community Property in California?

California is one of nine community property states in the United States. Under California Family Code §760, all property acquired by either spouse during the marriage while domiciled in California is presumed to be community property — owned equally (50/50) by both spouses.

This presumption applies regardless of whose name is on the title, whose income was used to purchase the asset, or who primarily used the property. The key question is simply: when was the asset acquired? If it was acquired during the marriage, it is presumed community property.

What Is Separate Property?

California Family Code §770 defines separate property as:

• Property owned by a spouse before marriage
• Property acquired during marriage by gift or inheritance, even from a third party
• Rents, issues, and profits derived from separate property
• Property acquired after the date of legal separation

Separate property is not subject to division in divorce — it belongs entirely to the spouse who owns it.

The "Title" Trap — A Common Misconception

One of the most common mistakes divorcing spouses make is assuming that whoever's name is on the title owns the asset. This is not how California community property law works. An asset titled in one spouse's name alone is still community property if it was acquired during the marriage with community funds. Conversely, an asset may be separate property even if both names are on the title.

Commingling — When Separate Becomes Community

Commingling occurs when separate property funds are mixed with community property funds to the point where the separate property can no longer be traced. If you cannot trace your separate property contribution with clear documentation, a California court may characterize the entire asset as community property.

Example: You bring $100,000 in separate property savings into a marriage and deposit it in a joint account. Over years of deposits and withdrawals, you can no longer trace that $100,000. It may be lost to the community — unless you have meticulous records.

Moore-Marsden Claims — Community Interest in Separate Property Real Estate

Under the Moore-Marsden formula established by California case law, when community funds are used to make payments on a spouse's separately owned real property, the community acquires a pro-rata interest in that property proportional to the community's contribution. This is an area where careful tracing and expert analysis are essential.

How Assets Are Divided in California Divorce

California Family Code §2550 requires courts to divide community property equally — each spouse receives one-half of the community estate. This does not mean every asset must be physically split. Instead, the parties (or the court) can award specific assets to each spouse in a way that achieves an overall equal division of the community estate's net value.

Common approaches include:

• One spouse buys out the other's interest in the family home
• One spouse receives the business; the other receives retirement accounts of equivalent value
• Assets are sold and proceeds divided equally
• A Qualified Domestic Relations Order (QDRO) divides retirement accounts between spouses

Debts in California Community Property

Just as assets acquired during marriage are community property, so too are debts incurred during the marriage. Both spouses may be liable for community debts regardless of whose name is on the account. This includes credit card debt, loans, and other obligations incurred for the community's benefit during the marriage.
