- Property division: community property — generally equal 50/50 split
- Divorce grounds: no-fault only — irreconcilable differences (Fam. Code § 2310)
- Minimum time to finalize: 6 months from date of service (Fam. Code § 2339)
- Domestic partnership: registered partners have essentially the same rights as spouses
California is one of nine community property states — a fundamental distinction that determines how marital assets and debts are divided at divorce. Combined with mandatory no-fault grounds, a domestic partnership system nearly equivalent to marriage, and one of the most sophisticated family court systems in the country, California family law has a distinctive character that doesn't translate directly from other states.
Community Property: What It Means and What It Doesn't
Community property is the default rule in California: assets and debts acquired by either spouse during the marriage belong equally to both spouses, regardless of who earned the money, whose name is on the account, or who made the purchasing decision. At divorce, community property is divided 50/50. This applies to wages earned during the marriage, retirement contributions made during the marriage, and real property purchased with marital funds — even if only one spouse's name is on the deed.
What is not community property is "separate property" — assets owned before the marriage, or received during the marriage by gift or inheritance. Separate property remains the acquiring spouse's property at divorce. The complication is that separate property can lose its character through "transmutation" (converting it to community property by agreement) or through "commingling" (mixing it with community assets). Tracing the separate property character of an account that received deposits from both separate and community funds is one of the most contested and expensive issues in California divorce.
Quasi-Community Property: The California-Specific Rule for Out-of-State Assets
California's quasi-community property doctrine addresses a situation that arises frequently in a mobile workforce. If you acquired property while living in another state that would have been community property had you been living in California at the time — income earned, property purchased — that property is treated as community property at divorce if you are domiciled in California when the divorce is filed. A couple who spent 10 years in Texas (a community property state) then 5 years in New York (an equitable distribution state), then divorces in California, will find their New York-acquired assets treated as community property under California's quasi-community property doctrine.
No-Fault Divorce: What This Actually Means
California was the first state in the country to adopt pure no-fault divorce, in 1969. Under Family Code § 2310, the only grounds for dissolution are irreconcilable differences that have led to the irremediable breakdown of the marriage, or incurable insanity. "Irreconcilable differences" requires no proof and no agreement from the other spouse — one party's statement that the marriage has broken down is sufficient. Marital fault — adultery, abandonment, cruelty — is irrelevant to the divorce itself.
However, fault is not completely irrelevant to all financial issues. A spouse who wastes or dissipates community assets — gambling away marital funds, making large gifts to a romantic partner, hiding assets — may be ordered to reimburse the community. This is called a "breach of fiduciary duty" claim under Family Code § 721.
Spousal Support in California
California courts award spousal support (alimony) based on the factors listed in Family Code § 4320, including the length of the marriage, each party's earning capacity, the marital standard of living, each spouse's age and health, and contributions to the other spouse's career or education. For marriages under 10 years, support is often ordered for roughly half the marriage length. For marriages over 10 years, California courts retain jurisdiction over support indefinitely — though this doesn't mean support is necessarily permanent, only that the court can revisit it.
California family courts use "DissoMaster" software to calculate temporary spousal support during the divorce proceeding. Long-term support is determined at trial or by agreement, and judges have substantial discretion.
Child Custody and Support
California custody law begins with the principle that frequent and continuing contact with both parents serves children's best interests (Fam. Code § 3020). Courts distinguish legal custody (decision-making authority over health, education, and welfare) from physical custody (where the child lives). Joint legal custody is the most common arrangement. Physical custody arrangements range from equal time-sharing to primary residence with one parent and scheduled visits with the other.
Child support in California is calculated by formula under Family Code § 4055 — the statewide "guideline" formula that accounts for each parent's net income, the percentage of time each parent has physical custody, and certain deductions. The formula output is presumptively correct; departing from it requires finding a specific statutory reason.
