California alimony laws, set out in Family Code Sections 4320 through 4360, govern how spousal support is calculated, how long it lasts, and when it can be changed or ended. The goal of a support order is to help the lower-earning spouse maintain something close to the standard of living established during the marriage. The same rules apply to divorces, legal separations, and dissolutions of registered domestic partnerships.
Two different sets of rules apply depending on where you are in the case. Understanding which one controls your situation is the first step.
Temporary Support vs. Long-Term Support
Temporary support covers the gap between filing and final judgment. Its job is simple: keep both households running while the case is pending. Because the court needs to move quickly, temporary support is calculated with guideline software certified by the Judicial Council.1Judicial Branch of California. Guideline Support Calculators Many counties use the Santa Clara formula as a starting point: roughly 40 percent of the higher earner’s net monthly income, minus 50 percent of the lower earner’s net monthly income. When child support is also at issue, that calculation runs first and the remaining income feeds the spousal support formula. Judges can deviate from the output, but most temporary orders stay close to it.
Long-term support is different. It replaces the temporary order once the court issues a final judgment, and it is built from a detailed, factor-by-factor analysis of both spouses’ circumstances. A long-term order specifies the amount, the schedule, and often an end date or triggering event. A temporary order carries no presumption about what the final award will look like.
How the Amount Is Decided
For long-term support, Family Code Section 4320 lists more than a dozen factors the judge must weigh on the record. No single factor controls, but in practice three carry the most weight: each spouse’s earning capacity, the marital standard of living, and the length of the marriage.
Earning Capacity
The court looks at whether each spouse can earn enough to sustain the lifestyle they had during the marriage. For the spouse requesting support, that means examining job skills, work history, and the time and cost of any retraining needed to re-enter the workforce.2California Legislative Information. California Code FAM 4320 – Factors to Be Considered in Ordering Support Years spent out of the job market raising children or managing the household are part of that analysis.
Either side can request a vocational evaluation under Family Code Section 4331. A court-appointed expert reviews the spouse’s education, health, age, work history, and the local job market, then estimates realistic earnings.3California Legislative Information. California Code FAM 4331 – Vocational Examination These reports carry weight. If an evaluator concludes you could earn $55,000 a year after six months of retraining, expect that figure to shape the support number. The court can also order the paying spouse to cover retraining costs.
Ability to Pay and Standard of Living
The paying spouse’s income, assets, separate property, and existing obligations all factor in. The court is looking at what they can actually afford without collapsing their own household. The marital standard of living serves as the benchmark, measured by how the couple actually lived in the later years of the marriage, not by aspirational budgets or lean early years.
Other Section 4320 Factors
- Contributions to the other spouse’s career or education, such as supporting them through professional school.
- Age and health of both parties.
- Whether a parent’s custody of young children limits their ability to work.
- The balance of hardships between the two spouses.
- Immediate tax consequences on each side.
The statute closes with a catch-all for any factor the court finds just and equitable.2California Legislative Information. California Code FAM 4320 – Factors to Be Considered in Ordering Support
Domestic Violence Changes the Calculation
Documented abuse can reshape an order. Section 4320 requires the judge to consider all evidence of domestic violence, including protective orders, convictions, and emotional impact. Section 4325 goes further: if a spouse was convicted of domestic violence within five years before the divorce was filed, or during the proceedings, there is a rebuttable presumption that the convicted spouse receives no support at all. The victim spouse also cannot be forced to pay the abusive spouse’s attorney fees from separate property.4California Legislative Information. California Code FAM 4325 – Domestic Violence and Spousal Support The convicted spouse carries the burden of overcoming that presumption.
How Long Support Lasts
Marriages Under 10 Years
The general expectation is that support lasts about half the length of the marriage. A six-year marriage typically produces roughly a three-year order.5California Courts. Long-Term Spousal Support This is a guideline, not a hard rule, and judges can order a longer or shorter term based on the Section 4320 factors.
Marriages of 10 Years or Longer
When a marriage lasted 10 years or more, measured from the wedding date to the date of separation, there is a presumption that it qualifies as a “marriage of long duration.” The court keeps jurisdiction over support indefinitely. Payments do not necessarily last forever, but neither spouse has to return to court before a deadline to keep the issue alive.6California Legislative Information. California Code FAM 4336 – Long Duration Marriage Jurisdiction A marriage shorter than 10 years can still be classified as long-duration if the circumstances justify it, and judges occasionally use that option for marriages that fell just short of the mark.
The Gavron Warning
Along with a long-term order, the court can formally warn the receiving spouse that they are expected to make reasonable efforts to become self-supporting. This is a Gavron warning, named for the 1988 appellate case and now codified in Family Code Section 4330(b).7California Legislative Information. California Code FAM 4330 – Spousal Support Orders The warning does not reduce support on its own. What it does is preserve the paying spouse’s ability to come back later and argue that the recipient hasn’t tried hard enough to find work or retrain. Courts look for concrete steps: job applications, enrollment in a program, updated certifications. Sitting idle after a Gavron warning is the fastest way to lose a support order. In long-duration marriages, the court can skip the warning, though that is relatively uncommon.
Tax Treatment
For any divorce finalized after December 31, 2018, alimony is not deductible by the payer and not reportable as income by the recipient on federal returns. The Tax Cuts and Jobs Act made that change permanent.8Internal Revenue Service. Divorce or Separation May Have an Effect on Taxes
California handled this separately until recently. Before 2026, the state still let the payer deduct alimony and required the recipient to report it as income for state tax purposes. Starting January 1, 2026, California conforms to the federal rule. Alimony paid under agreements executed on or after that date is no longer deductible by the payer or taxable to the recipient for California income tax purposes. Agreements executed before that date are grandfathered unless a modification expressly adopts the new treatment.9State of California Franchise Tax Board. Alimony
This affects the support number itself. Because the payer no longer offsets payments against their tax bill, judges tend to account for that in setting the award. The practical result is often a lower gross payment than would have been ordered under the old rules.
When Support Can Be Modified or Ended
Automatic Termination
Unless the parties agreed otherwise in writing, support ends automatically when either spouse dies or the receiving spouse remarries.10California Legislative Information. California Code FAM 4337 – Spousal Support Termination No court filing is required, though the payer should document the termination to avoid confusion later.
Changed Circumstances
Outside death and remarriage, modifying an order requires showing a material change in circumstances since the last order. A major job loss, a serious illness, a substantial inheritance, or a significant income increase on either side can qualify. A roughly 20 percent drop in the payer’s earnings is often enough to justify a hearing. Whichever side seeks the change carries the burden.
A modification can be made retroactive to the date the request was filed, so delay has a cost.11California Legislative Information. California Code FAM 4333 – Retroactive Support Orders
Cohabitation
If the receiving spouse moves in with a romantic partner, Family Code Section 4323 presumes their financial need has decreased. The paying spouse can petition to reduce or end support by showing that shared living expenses have lowered the recipient’s actual needs.12California Legislative Information. California Code FAM 4323 – Cohabitation and Spousal Support The recipient can rebut the presumption but carries the burden of proving need hasn’t actually changed. The couple does not need to hold themselves out as married for the presumption to apply.
Retirement
Reaching retirement age can qualify as a material change, but it does not automatically end support. Courts evaluate whether the retirement was reasonable and made in good faith. Retiring at or near full Social Security retirement age generally passes that test. Retiring at 52 to play golf while an ex-spouse depends on the payments does not. If a court finds the retirement was mainly motivated by avoiding support, it can impute income to the payer as if they were still working. In long-duration marriages, retirement may reduce support rather than eliminate it, especially where the payer has pension income or other retirement assets.
Enforcement When Payments Stop
A support order is a court directive. Under Family Code Section 290, the court can enforce it through wage garnishment, appointment of a receiver, contempt proceedings, or any other remedy the judge finds appropriate.13California Legislative Information. California Code FAM 290 – Enforcement of Judgments and Orders
The most common tool is an earnings assignment order, which directs the payer’s employer to deduct support from each paycheck and send it to the recipient. It is often ordered as a default mechanism.
Unpaid support accrues interest at 10 percent per year, and the balance grows quickly.14California Courts. Paying Spousal Support For persistent nonpayment, the receiving spouse can pursue contempt, which is treated as a criminal matter. Penalties can include jail time, community service, fines, and an order that the delinquent spouse pay the other side’s attorney fees.
Registered Domestic Partners
Registered domestic partners have the same support rights as married couples. The court applies the same Section 4320 factors, the same duration guidelines, and the same modification rules. The only difference is terminology: what is called “spousal support” in a marriage is “domestic partner support” or “partner support” in a partnership dissolution.15California Courts. Spousal Support
