California Divorce Financial Planning: Community Property, CalPERS & Spousal Support

California is a community property state — every dollar earned and every asset acquired from the date of marriage through the date of separation is presumed to be owned equally. That 50/50 default sounds simple. It isn't. A CalPERS pension requires its own court order, business goodwill is community property in California in ways it isn't in other states, and the widely cited "10-year rule" for spousal support is a legal myth that has cost people real money. Here's what the rules actually say — and what they mean for your settlement.

1. What counts as community property

California Family Code § 760 establishes the community property presumption: all property acquired by either spouse during the marriage while domiciled in California is community property.¹ In practice, this means:

• Wages and salaries earned during the marriage — even if deposited in an account held only in one spouse's name
• Business interests started or grown during the marriage (including appreciation, retained earnings, and goodwill — see Section 4 below)
• Retirement account contributions made from date of marriage through date of separation, plus investment growth on those contributions
• Real estate purchased with marital funds, even if titled in one name
• Stock and RSU vesting during the marriage (grants that straddle the marriage/separation date require time-rule apportionment)

The division standard under FC § 2550 is equal — each spouse receives half the net community property value.¹ You can negotiate an unequal split by written agreement, but the court's default on any contested item is 50/50.

2. The date of separation — California's key financial cutoff

California Family Code § 70 (effective January 1, 2017) defines the date of separation (DOS) as the date when a complete and final break in the marital relationship has occurred, evidenced by: (1) a spouse's expressed intent to end the marriage, and (2) conduct consistent with that intent.¹

The DOS matters enormously for asset valuation. Income earned after the DOS is separate property — the employee spouse keeps it. Retirement account contributions after the DOS are separate. A business that grows significantly after the DOS may have a meaningful separate-property component.

In high-asset divorces, the DOS is frequently contested. If one spouse moved out but continued using joint accounts, or if the couple had an extended "in-home separation," determining the exact DOS requires documentation: emails, financial records, and witness testimony. A CDFA's job includes modeling the financial difference between competing DOS dates — the gap can be hundreds of thousands of dollars in a high-income household.

3. Automatic Temporary Restraining Orders (ATROs)

When divorce papers (a Summons, FL-110) are served in California, a set of Automatic Temporary Restraining Orders (ATROs) takes effect immediately — without any hearing — under Family Code § 2040.¹ ATROs prohibit both parties from:

• Transferring, encumbering, hypothecating, concealing, or disposing of any community or separate property without written consent or court order (with exceptions for ordinary business expenses and attorney fees)
• Canceling, modifying, or changing beneficiaries on any life, health, auto, or disability insurance
• Creating or modifying a nonprobate transfer (trust, TOD, POD designation)
• Removing the other spouse or minor children from any insurance coverage

ATROs are the financial equivalent of a freeze order. If you sell assets, move money out of joint accounts above ordinary living expenses, or change a beneficiary designation after service, you face contempt and the court may order you to reverse the transaction and pay the other side's attorney fees. Understand what you can and can't do before you spend anything from shared accounts after papers are filed.

4. Financial disclosure: FL-150 and FL-142

California requires both parties to exchange preliminary and final Declarations of Disclosure — sworn documents that are the financial backbone of every CA divorce. The two key forms are:³

• FL-150 — Income and Expense Declaration: all sources of income, monthly expenses, assets, and debts. Must be current (typically within 90 days) for any hearing on support.
• FL-142 — Schedule of Assets and Debts: complete inventory of every asset and debt, with current values, date acquired, and separate vs. community designation.

Failing to disclose an asset in the FL-142 is grounds for the court to award the entire asset to the other spouse — even years after a judgment is entered (FC § 2556 provides ongoing jurisdiction to divide omitted assets).¹ In high-asset cases, this is where the CDFA's forensic skills matter: business interests, deferred compensation, unvested equity, and crypto holdings are commonly under-disclosed or misvalued on an opponent's disclosure forms.

5. CalPERS and public pension division: the DRO Joinder process

CalPERS — the California Public Employees' Retirement System — is the pension for state employees, teachers (in some districts), and many local government workers. CalPERS is a government plan, not an ERISA-covered plan. It is not subject to the federal QDRO rules that apply to private-employer 401(k) and pension plans.⁴

How it works instead:

1. Joinder: Before the divorce can divide the CalPERS benefit, CalPERS must be joined as a party to the case under Family Code § 2060. The joinder freezes the member's account and prevents unauthorized benefit changes during the proceeding.⁴
2. Domestic Relations Order (DRO): The court issues a DRO — often using CalPERS model orders — specifying the non-member spouse's share. CalPERS then reviews the DRO for administrative approval before it becomes effective.
3. Time rule: For defined benefit pensions, the community share is typically calculated using a time rule: months of credited service during the marriage ÷ total months of credited service at retirement, multiplied by the monthly benefit. The non-member spouse receives their share of the community interest.

CalPERS also covers teachers at many California school districts through CalSTRS (California State Teachers' Retirement System). CalSTRS has its own separate DRO process distinct from CalPERS — if your spouse is a teacher, the division order must comply with CalSTRS administrative rules, not CalPERS.

6. Business goodwill: a California difference

In most states, courts draw a sharp line between enterprise goodwill (which is divisible as marital property) and personal goodwill (the value attributable to an individual's personal reputation and relationships, which is considered separate in many states). California has historically treated goodwill of a business — including some personal goodwill components — as community property subject to equal division.⁵

For a medical practice, law firm, or professional service business, this distinction is financially significant. In a state that excludes personal goodwill, the business value in a divorce is often dramatically lower than a full fair-market-value appraisal. In California, the non-owning spouse may argue for a share of professional goodwill that other states would exclude.

Two practical consequences for settlement:

• Business valuations in California divorces are frequently more contested — and more expensive — than in other states. Both sides typically retain separate appraisers.
• The after-tax value of the business interest matters: any buyout paid to the non-owning spouse under IRC § 1041 transfers the tax basis, not the cash — meaning the structure of the buyout (installment payments, offset against other assets, deferred earn-out) has real tax consequences that a CDFA should model.

7. Spousal support: what FC §4336 actually says

California does not use the word "alimony." It's spousal support — and the rules differ meaningfully from most states.

The 10-year myth: You will hear that marriages of 10 years or more trigger "permanent alimony" in California. This is a misreading of the law. Family Code § 4336(b) creates a presumption that marriages of 10 or more years (from date of marriage to date of separation) are "marriages of long duration" — meaning the court retains indefinite jurisdiction to modify or terminate support, rather than setting a specific end date at the outset.⁶ Retention of jurisdiction is not the same as an order for permanent support. Courts terminate support for long-duration marriages regularly when the supported spouse becomes self-supporting.

How California courts set support: Family Code § 4320 lists the factors courts weigh, including:¹

• The standard of living established during the marriage (the baseline — CA courts are explicit about this)
• Each party's marketable skills, job market, and earnings capacity
• The extent to which one spouse's earning capacity was reduced by periods of unemployment during the marriage (career-sacrifice situations weigh heavily)
• Each party's assets and obligations
• The duration of the marriage
• Age and health of both parties
• Documented history of domestic violence

The Gavron Warning: Established in Marriage of Gavron (1988) and codified in FC § 4330, courts may include a "Gavron Warning" in support orders — formally notifying the supported spouse that they are expected to become self-supporting within a reasonable time.¹ Failure to make reasonable good-faith efforts to become self-supporting is a factor courts can use to modify or terminate support later.

Post-TCJA note: California conforms to federal law for alimony tax treatment. For divorces finalized after December 31, 2018, spousal support is neither deductible by the payer nor included in the recipient's taxable income under IRC § 71 (as repealed by TCJA § 11051). This materially changes the settlement math — a CDFA models the after-tax present value of the support obligation for both parties. See our alimony tax treatment guide for a full breakdown.

8. Separate property in California: what you can protect

California recognizes three categories of separate property: assets owned before marriage, inheritances received at any time (even during the marriage), and gifts received by only one spouse. These are protected from equal division — but only if you can prove their separate character.

Where Californians lose separate property protection:

• Commingling: A pre-marital $200,000 investment account that received marital paycheck deposits becomes difficult to trace. California uses the "direct tracing" method — you need documentation showing the original separate funds can be identified through the mixed account's history.
• Transmutation: Under FC § 852, a spouse can change the character of separate property to community property (or vice versa) through a written agreement that expressly states the transmutation.¹ Adding a spouse's name to the title of a separately owned home may constitute a transmutation — courts look at intent and the specific language used.
• Active appreciation vs. passive appreciation: If a separately owned business actively grew during the marriage due to the efforts of either spouse, the appreciation may be community property (a Pereira or Van Camp calculation). If growth was purely passive (market appreciation on a pre-marital investment account you didn't touch), it stays separate.

Tracing and documenting separate property is one of the highest-value things a CDFA does in high-asset California divorces. The documentation burden is on the spouse claiming separate character — not on the other side to disprove it.

The CDFA's role in a California divorce

California-specific complexity — CalPERS DROs, business goodwill debates, commingling traces, the ATROs calendar, the FL-150/FL-142 disclosure review — stacks on top of the federal financial issues every divorce involves (QDRO mechanics for private plans, post-TCJA support tax treatment, carryover basis traps under IRC § 1041, IRMAA from divorce-year income spikes).

A CDFA-credentialed fee-only financial advisor in a California practice models all of it: after-tax present value of support, CalPERS community-share calculation, business valuation forensics, and a side-by-side settlement equivalency analysis before the MSA is signed. Unlike a divorce attorney, a CDFA charges for financial expertise specifically — and has no incentive to push a particular product or outcome.

5. California case law on business goodwill as community property. California courts have historically treated business goodwill — including professional practice goodwill — as community property subject to division. The characterization of goodwill in a California divorce requires forensic business valuation; the split between enterprise and personal goodwill components is actively litigated in high-asset cases.
6. California Family Code § 4336 — Retention of Jurisdiction; Long-Duration Marriage. FC § 4336(b): presumption that marriages of 10 or more years (date of marriage to date of separation) are marriages of long duration, triggering retained jurisdiction over spousal support modification. Retention of jurisdiction ≠ guaranteed permanent support. Courts retain discretion to terminate support on a showing of changed circumstances.
