Quick Answer: Partly. California is a community property state, and Family Code section 2550 requires the court to divide the community estate equally unless the spouses agree otherwise in writing or by oral stipulation in open court. But not everything is split 50/50. Separate property, such as assets owned before marriage, gifts, and inheritances, stays with its owner, and reimbursement claims can shift the numbers. Spousal support is set by statutory factors, not a percentage, child support follows a formula, and California has no presumption in favor of 50/50 custody.
"Fifty-fifty" is the most common thing people have heard about California divorce. It is a useful starting point for property, and almost entirely wrong for custody and support. Here is how each piece actually works.
What Is Community Property?
Family Code section 760 provides that, except as otherwise provided by statute, property a married person acquires during the marriage while living in California is community property. Earnings during marriage, a home bought with marital income, retirement contributions, and stock compensation earned during marriage are typical examples.
What Is Separate Property?
Family Code section 770 defines separate property as property owned before marriage, property acquired by gift, bequest, devise, or descent, and the rents, issues, and profits of that property. Earnings and accumulations after the date of separation are also separate property under Family Code section 771. That is why the date of separation can matter so much.
What Does "Equal Division" Actually Mean?
Section 2550 requires an equal division of the community estate. Equal means equal in value, not that every asset is cut in half. One spouse may keep the house while the other keeps the retirement accounts, with an equalization payment to balance the difference. Under Family Code section 2552, assets and debts are generally valued as near as practicable to the time of trial, although on 30 days' notice the court may, for good cause, use a later date after separation for some or all of them. Our property division page explains how the process works from start to finish.
Exceptions and Adjustments to the 50/50 Split
Reimbursement for separate property contributions. Under Family Code section 2640, a spouse who traces separate funds into a community asset, such as a down payment, may be reimbursed before the rest is divided. See our Family Code 2640 post.
Separate property and the family home. When separate funds paid down a mortgage before marriage, a Moore/Marsden calculation may give the separate estate a share of the appreciation.
Epstein credits and Watts charges. Post-separation mortgage payments and one spouse's exclusive use of an asset can create credits and charges that change the final numbers.
Breach of fiduciary duty. Under Family Code section 1101, a court can award a spouse 50 percent of an asset that was undisclosed or transferred in breach of fiduciary duty, plus attorney's fees and costs, or 100 percent when the breach involved fraud, oppression, or malice.
Special categories. Student loans and education costs (Family Code section 2641) and personal injury damages (section 2603) follow their own rules.
Agreements. A valid prenup, postnup, or transmutation can change what is community and what is separate.
How Are Debts Divided?
Debts incurred during the marriage and before separation are divided along with the assets under Family Code section 2622, and when community debts exceed community assets, the court assigns the excess as is just and equitable, considering factors such as each spouse's ability to pay. Under Family Code section 2623, debts incurred after separation but before judgment for nonnecessaries are confirmed to the spouse who incurred them. Debts for the common necessaries of life of either spouse or the children are confirmed according to each spouse's needs and ability to pay when the debt was incurred, unless a support order or written agreement covers them.
Spousal Support Is Not a Percentage
Long-term spousal support is based on the factors in Family Code section 4320, including the marital standard of living, each spouse's earning capacity, the length of the marriage, and the supported spouse's ability to become self-supporting. Our 4320 post explains the factors. Courts often use guideline software for temporary support, but long-term support is a discretionary judgment, not a 50/50 split of income.
Duration varies too. For a marriage that is not of long duration, section 4320(l) says a reasonable period for the supported spouse to become self-supporting is generally one-half the length of the marriage, although the court may order more or less. For a marriage of 10 years or more, measured from marriage to separation, Family Code section 4336 presumes a marriage of long duration, and the court generally keeps jurisdiction over support indefinitely. That does not mean support lasts forever.
Is 50/50 Custody the Default?
No. Family Code section 3040(e) establishes neither a preference nor a presumption for or against joint or sole custody. Section 3020 states a policy of frequent and continuing contact with both parents, but the child's health, safety, and welfare come first. A 50/50 schedule is common when parents live near each other and cooperate, but it is one option, not the starting point. Our guide to 50/50 custody schedules compares the common rotations if equal time fits your family.
Child Support Is Formula-Based
Child support follows the statewide guideline in Family Code section 4055, which considers both parents' incomes and each parent's share of parenting time. Equal parenting time does not mean no child support. If incomes differ, the higher earner usually still pays.
Why the Separation and Valuation Dates Matter
Two dates shape what "50/50" means in practice. The date of separation, defined in Family Code section 70, marks when earnings stop being community property, so a few months' difference can change the community share of a bonus, vesting equity, or retirement contributions. The valuation date, generally near trial under section 2552, sets what each asset is worth when it is divided. In a rising or falling market, especially for stock and real estate, that choice can shift the result substantially. Both dates can be negotiated or litigated, and both deserve attention early.
Key Takeaways
Pin Down the Separation Date
Gather texts, leases, and account changes that show when the marriage actually ended, because that date controls what is community.
Collect Pre-Marriage Statements
Account statements from before the wedding are often the key evidence for proving that an asset is separate property.
Update Values Before Settlement
Values are normally set near trial, so refresh appraisals and account statements before you sign a settlement.
Watch Debts in Your Name
A creditor can still pursue you on a joint debt even if the judgment assigns that debt to your spouse.
Frequently Asked Questions
Does California split everything 50/50 in a divorce? No. Only the community estate is divided equally. Separate property stays with its owner, and support and custody follow different rules.
Is the house automatically split 50/50? If the house is community property, its equity is part of the equal division. If one spouse contributed separate funds, a section 2640 reimbursement or a Moore/Marsden interest may come off the top first.
Does my spouse get half of my retirement? Generally, the community portion, meaning what was earned during the marriage and before separation, is divided equally. Contributions made before marriage or after separation are usually separate property.
Can we agree to something other than 50/50? Yes. Spouses can agree to an unequal property division in a written agreement or by oral stipulation in open court under section 2550.
