California Community Property Rules in a Divorce
What counts as community and separate property, how California splits it 50/50 in a divorce, reimbursements, debts, the family home and retirement accounts.
California is a community property state: almost everything either spouse earns or acquires during the marriage belongs to both equally, and in a divorce the community estate is split 50/50 (Family Code 2550). Property owned before marriage, gifts and inheritances are separate property and stay with their owner. Traceable separate money put into community property is reimbursed first, and community debts are split along with the assets.
Community or separate?
| Community property (shared) | Separate property (one spouse) |
|---|---|
| Wages and salary earned during the marriage | Anything owned before the marriage |
| Homes, cars and accounts bought with those earnings, whoever's name is on title | Gifts and inheritances to one spouse, even during the marriage |
| The part of a 401(k), IRA or pension earned during the marriage | Income and growth from separate property (rent, dividends, appreciation) |
| Property bought during marriage in joint names (presumed community) | Earnings after the date of separation |
| Debts taken on during the marriage for the family | Debts from before the marriage or after separation |
The starting rule is Family Code 760: property acquired during the marriage while living in California is community property. Whoever claims something is separate has to prove it, usually by tracing it to a separate source with records. Separate money mixed into a joint account can become impossible to trace and end up treated as community. Spouses can change the character of property on purpose only with a written "transmutation" that expressly says so and is signed by the spouse who gives up the interest (Family Code 852).
How the 50/50 split works
- List and classify every asset and debt as community or separate.
- Value the community items, usually as close to trial as practical.
- Reimburse separate contributions (see below).
- Divide what's left equally. The court doesn't split each item in half; it gives items to one spouse or the other so the totals are equal, and orders an equalization payment when they aren't (Family Code 2601).
Spouses can agree to a different split in a written settlement, and a valid prenuptial agreement can change the rules entirely.
Getting your separate money back (Family Code 2640)
If you put traceable separate money into a community asset, such as an inheritance used for the down payment on a home bought during the marriage, you get that amount back before the rest is divided. The reimbursement is the dollar amount only: no interest and no share of appreciation, and it can't exceed the asset's net value. Payments of interest, taxes, insurance and maintenance don't count. A signed written waiver ends the right.
The family home bought before marriage
A home one spouse bought before the wedding stays that spouse's separate property. But when community earnings pay down the mortgage during the marriage, the community earns a share under the Moore/Marsden formula: the community gets back the principal it paid, plus that same percentage of the purchase price applied to the appreciation during the marriage.
Example: a $400,000 home bought with $80,000 down; $20,000 of principal paid before the wedding, when it was worth $450,000; $60,000 of principal paid with community earnings during the marriage; worth $700,000 today. The community paid 15% of the price, so its share is $60,000 + 15% of $250,000 = $97,500, split between the spouses. The owner keeps the other $362,500 of the $460,000 equity as separate property.
Debts
Debts incurred during the marriage are divided along with the assets. If community debts are larger than community assets, the court can assign the excess based on each spouse's ability to pay instead of 50/50 (Family Code 2622). Debts from before the marriage, debts after separation, and debts not incurred for the benefit of the community stay with the spouse who incurred them (Family Code 2625). A divorce judgment doesn't bind creditors: if a joint card is assigned to your ex and they don't pay, the lender can still come after you.
Retirement accounts and businesses
Only the part of a 401(k), pension or IRA earned during the marriage is community property. Splitting a 401(k) or pension usually takes a court order called a QDRO so the transfer isn't taxed as a withdrawal. A business started during the marriage is community property; one started before it can still gain a community share if a spouse's work during the marriage increased its value.

Frequently Asked Questions
Is California a 50/50 divorce state?
Yes for property. Family Code 2550 requires an equal division of the community estate (community assets minus community debts) unless the spouses agree otherwise in writing or in court. Support and custody are decided separately and are not 50/50 rules.
Is a house bought before marriage community property?
No, it stays the buyer's separate property. But if community earnings paid down the mortgage during the marriage, the community gets a share of the equity under the Moore/Marsden formula.
Is an inheritance community property in California?
No. Gifts and inheritances received by one spouse are separate property (Family Code 770). They can become mixed with community property if they are deposited into a joint account or used for community purchases, so keeping them separate and documented matters.
Are debts split in a California divorce?
Debts incurred during the marriage are community debts and are divided along with the assets. Debts from before the marriage or after separation, and debts not incurred for the benefit of the community, stay with the spouse who took them on.
When does community property stop accumulating?
At the date of separation. Earnings and accumulations after that date are each spouse's separate property (Family Code 771). The date of separation is when one spouse has told the other they intend to end the marriage and their conduct is consistent with that.
