Community vs. separate property in California

Evenpart · October 30, 2026 · 4 min read

California is a community property state. In general, property and debts acquired by either spouse during the marriage and before the date of separation are community and divided equally in a divorce, unless the spouses agree otherwise in writing or on the record in court. Property owned before marriage, acquired after separation, or received by gift or inheritance is generally separate and stays with its owner. Mixing funds, changing title, and moving between states can complicate the picture, so characterization often depends on records and tracing.

The basic definitions

Family Code section 760 provides that, except as otherwise provided by statute, all property acquired by a married person during the marriage while domiciled in California is community property. That includes wages earned during the marriage, items bought with those wages, and retirement benefits earned during the marriage.

Family Code section 770 defines separate property as property owned before the marriage, property acquired during the marriage by gift, bequest, devise, or descent, and the rents, issues, and profits of that property. Under section 771, earnings and accumulations after the date of separation are also generally separate. Under section 2550, unless the spouses agree otherwise in writing or by oral stipulation in open court, the court divides the community estate equally.

Why the date of separation matters

Family Code section 70 defines the date of separation as the date a complete and final break in the marital relationship occurred, shown by both of the following: one spouse expressed to the other the intent to end the marriage, and that spouse's conduct was consistent with that intent. The court considers all relevant evidence, and spouses do not have to agree on the date.

The date matters because income and property acquired after it are generally separate, and it also affects the length of the marriage for spousal support purposes. Moving out, telling family, opening separate accounts, and starting divorce planning can all be relevant, but no single event decides it.

Commingling, tracing, and transmutation

Commingling happens when separate and community money are mixed, for example when an inheritance is deposited into a joint account used for household bills. Mixing does not automatically make everything community, but the spouse claiming a separate interest generally needs to trace it with records. Without reliable records, commingled funds may be treated as community. Separate property contributions to buying community property may also give rise to reimbursement claims under Family Code section 2640.

Transmutation is an agreement that changes the character of property, such as turning separate property into community property. Under Family Code section 852, a transmutation is valid only if it is made in writing with an express declaration, made, joined in, consented to, or accepted by the spouse whose interest is adversely affected. There is a limited exception for gifts between spouses of personal items, such as jewelry or clothing, that are not substantial in value considering the circumstances of the marriage.

Quasi-community property and debts

If you lived in another state during part of the marriage and then moved to California, property acquired there that would have been community property if you had lived in California is called quasi-community property under Family Code section 125. In a California divorce, it is generally divided as if it were community property.

Debts follow similar rules, with some important differences.

Debts incurred during the marriage and before separation are generally community debts, even if only one spouse's name is on the account.
Debts incurred before the marriage or after separation are generally assigned to the spouse who incurred them, though debts for the necessities of life after separation can be treated differently.
Education loans for one spouse are generally assigned to that spouse, and the community may be entitled to reimbursement in some cases.
A divorce judgment divides debts between the spouses, but a creditor may still pursue a person whose name is on an account, so ask an attorney how to protect yourself.

Your next steps

List every asset and debt with the date and source of acquisition, and keep statements that show where separate money came from.
Think carefully about your date of separation and the facts that support it.
Before signing any document that changes title or ownership between spouses, or when significant assets were commingled, talk with an independent family-law attorney licensed in California.
