California High-Net-Worth Divorce: 2026 Rules and Figures
California splits community property equally by default. Child support's top band, from Sept. 1, 2024, covers combined net income over $15,000 a month.
By Aparti Editorial Team
California divides a high-net-worth couple's community estate equally unless a Family Code §2550 exception applies. The practical effect: the money is decided earlier, by classification, valuation date, disclosure and reimbursement of traced separate property. Child support has no income cap; §4057(b) lets a court depart from the guideline where an extraordinarily high earner's guideline amount exceeds the children's needs.
Key figures
- Over $15,000/month combined net disposable income: top child-support band since September 1, 2024 (§4055).
- 10 years, marriage to separation: long-duration presumption for retaining jurisdiction (§4336).
- 107,146 marital filings, fiscal year 2024-25 (Judicial Council).
- January 1, 1994: community property section operative (§760).
What counts as community property in a California divorce?
Property a married person acquires during the marriage while domiciled in California is community property, unless a statute provides otherwise. That is Family Code §760, operative since January 1, 1994. It covers real or personal property wherever located.
Section 770 lists what stays separate:
- Property a spouse owned before marriage.
- Property acquired after marriage by gift, bequest, devise or descent.
- The rents, issues and profits of that property.
Section 771 draws the line at the far end. A spouse's earnings and accumulations after the date of separation are that spouse's separate property.
In a divorce or legal separation, §2550 requires equal division of the community estate, in the judgment or later if the court expressly reserves jurisdiction. The three exceptions are a written agreement, a stipulation in open court, or another provision of the same division of the Family Code (Division 7, on division of property).
When are assets and debts valued in a California divorce?
A California court values assets and debts as near as practicable to the time of trial, under Family Code §2552. Section 2552(b) lets it instead value all or any portion of them at a date after separation and before trial. That takes 30 days' notice by the moving party and good cause shown.
Read together, §2550 and §2552 mean the date chosen fixes which number gets divided when an estate's largest asset, such as an operating business or a concentrated stock position, moves in value.
What disclosure do spouses owe each other in a California divorce?
In a California divorce, disclosure comes as a preliminary declaration early on and a final one at settlement or before trial.
- Preliminary declaration of disclosure. Under §2104(f), each spouse serves it with the petition or response, or within 60 days of filing it. Written agreement or court order can extend those dates.
- Final declaration of disclosure. Under §2105(a), it is due by the time the parties agree on property or support, other than pendente lite support. If the case goes to trial, it is due no later than 45 days before the first assigned trial date. A court can order otherwise for good cause. Section 2105(d) lets the parties waive the final declaration by mutual stipulation, made under penalty of perjury.
Family Code §721 makes the relationship between spouses a confidential one that requires the highest good faith and fair dealing. It gives each spouse the same rights and duties as nonmarital business partners under Corporations Code §§16403, 16404 and 16503.
Family Code §1101 provides for an award to the injured spouse of 50 percent of any asset undisclosed or transferred in breach of fiduciary duty, plus attorney's fees and court costs. Where the breach falls within the ambit of Civil Code §3294 (oppression, fraud or malice), the award is 100 percent of that asset.
When is separate property reimbursed in a California divorce?
A California spouse is entitled to reimbursement, on division, for contributions to acquiring community property that are traced to a separate property source. Under Family Code §2640, the right is lost if that spouse made a written waiver or signed a writing with that effect.
Down payments, payments for improvements, and principal paid down on a loan used to buy or improve the property all count. Interest, maintenance, insurance and taxes do not. Reimbursement is "without interest or adjustment for change in monetary values" and "may not exceed the net value of the property at the time of the division."
Take a hypothetical, not a real case. A spouse inherits $400,000 during the marriage, separate property under §770. The spouse uses it as the down payment on a home the couple buys as community property. If the spouse can trace the down payment to the inheritance and signed no waiver, §2640 sets the claim at $400,000, with no interest and no inflation adjustment. If the home's net value at division is $300,000, the claim stops at $300,000.
How does marriage length affect spousal support in California?
Except in a long-duration marriage, a California supported spouse's "reasonable period of time" to become self-supporting "generally shall be one-half the length of the marriage." That is Family Code §4320, in subdivision (l) as currently lettered. The same section says that nothing in it limits the court's discretion to order support for a greater or lesser length of time. The court may do so based on the section's other listed factors, §4336 and the parties' circumstances.
Section 4336 draws the long-duration line. For the purpose of retaining jurisdiction, a marriage of 10 years or more is presumed to be of long duration. The presumption affects the burden of producing evidence. The marriage is measured from the date of marriage to the date of separation, and the court may consider periods of separation during it. The statute also says nothing in that subdivision precludes a court from determining that a marriage of less than 10 years is a marriage of long duration.
On the statute's terms, a couple who separate nine years and eight months after the wedding fall short of the 10-year presumption, but a court is not barred from treating the marriage as long in duration.
Does California cap child support for high earners?
California's child support formula has no income cap. Its top band, from September 1, 2024, covers combined net disposable income over $15,000 a month. Under §4057(b), as amended effective September 1, 2024, the guideline presumption can be rebutted where the paying parent's income is extraordinarily high and the guideline amount exceeds the children's needs.
The guideline, Family Code §4055, was replaced by SB 343 (Stats. 2023, ch. 213), operative September 1, 2024. SB 343 kept the guideline formula and changed its K-factor table. That table sets the multiplier K by the parents' total net monthly disposable income (TN).
Under the table from September 1, 2024, K for TN over $15,000 a month is 0.12 + 1,200/TN, before a further statutory adjustment. Before September 1, 2024, the top band was TN over $10,000, with K = 0.12 + 800/TN. That band was open-ended too, and it is superseded.
Arithmetic on the table from September 1, 2024 gives a top-band K of 0.160 at combined net disposable income (TN) of $30,000 a month. The superseded band gives 0.147 at the same income. Neither number is printed in the statute. Each is a multiplier before the statute's further adjustment, not a support amount.
How long does a California divorce take to become final?
In California, marital status ends no sooner than six months after service of the summons and petition or the respondent's appearance, whichever is earlier. That is Family Code §2339. The court can extend the period for good cause. The wait governs marital status only, not property division or support.
Under §2320, no divorce judgment can be entered unless one spouse meets a residency rule, except as §2320(b) provides. That spouse must have been a California resident for six months, and a resident of the filing county for three months, immediately before the petition is filed.
How many divorce and separation cases are filed in California each year?
The Judicial Council's 2026 Court Statistics Report records 107,146 marital filings in California superior courts in fiscal year 2024-25. It counts cases filed, not divorces completed. It combines dissolutions, legal separations and nullities.
CDC does not publish a California divorce rate. Its Stats of the States page for California lists the 2024 divorce rate as "Not reported."
