California spousal support is money one spouse pays the other during or after a divorce to keep the lower earner from falling into financial hardship. Courts set a temporary amount using a county software formula while the case is pending, then set a longer-term amount by weighing the factors in Family Code Section 4320. How long payments last depends heavily on the length of the marriage, with the ten-year mark being the single most important dividing line.
How Support Is Calculated
There are two different awards in most cases, and they run on different rules.
Temporary support covers the gap between filing and the final judgment, so both households can keep running while the case moves. Most California counties calculate it with software called DissoMaster or XSpouse. The common guideline is roughly 40 percent of the higher earner’s net monthly income minus 50 percent of the lower earner’s net monthly income. If the higher earner nets $8,000 a month and the lower earner nets $2,000, the guideline amount comes out around $2,200. Judges can deviate from the number, but the formula gives everyone a quick starting point.
Permanent support (sometimes called long-term or post-judgment support) works differently. There is no formula. Instead, Family Code Section 4320 lists more than a dozen factors the judge must weigh, with the marital standard of living as the benchmark — not a cap, but the reference point for whether the award is reasonable.1California Legislative Information. California Code FAM 4320 The factors that tend to carry the most weight:
- Each spouse’s earning capacity, including job skills, the current market for those skills, and the time and money needed for any retraining. A spouse who left the workforce for childcare or household duties gets credit for how that gap hurt their future earning power.
- The paying spouse’s ability to pay, looking at earned and unearned income, assets, and existing obligations.
- Contributions one spouse made to the other’s education, training, career, or professional license.
- The age and health of both parties.
- Any documented history of domestic violence, which can push an award up for a victim or down for an abuser.1California Legislative Information. California Code FAM 4320
- Immediate tax consequences on each side.
- The overall balance of hardships.
Two cases with identical paychecks can produce very different awards once these factors come into play.
How Long Support Lasts
Duration turns on the length of the marriage, measured from the wedding date to the date of separation.
For marriages under ten years, the general guideline is support for about half the length of the marriage. A six-year marriage produces roughly three years of support. That benchmark comes straight out of Section 4320(l), which defines a “reasonable period of time” for the supported spouse to become self-sufficient as generally one-half the length of the marriage.1California Legislative Information. California Code FAM 4320 Judges can go longer or shorter depending on the other factors.
For marriages of ten years or more, the court treats the marriage as one of long duration and keeps jurisdiction over support indefinitely, unless the parties agree in writing to a cutoff or the court later terminates the obligation.2California Legislative Information. California Code FAM 4336 Indefinite jurisdiction does not mean support lasts forever. It means the judge does not set an end date up front and keeps the power to revisit the issue. A shorter marriage can also qualify as long duration if the circumstances support it.
The Gavron Warning
When the court issues a permanent order, it can include a Gavron warning — a formal notice that the supported spouse is expected to make reasonable efforts to become self-supporting. The authority is in Family Code Section 4330(b).3California Legislative Information. California Family Code 4330 Reasonable efforts can include applying for jobs, pursuing training or education, obtaining professional licenses, or accepting suitable employment when offered.
Ignoring a Gavron warning gives the paying spouse ammunition for a later motion to reduce or end support. If you receive support and a warning has been issued, keep records of applications, courses, and other job-search efforts. That paper trail is your defense if your ex argues you haven’t tried.
Vocational Evaluations
Either side can ask the court to order a vocational evaluation under Family Code Section 4331. A vocational counselor weighs the supported spouse’s age, health, education, work history, and marketable skills against the current job market, then reports a realistic earning capacity.4California Legislative Information. California Code FAM 4331 The court can order the supporting spouse to pay for the evaluation and for retraining the evaluation recommends. These reports often shape both the amount of support and how fast it steps down.
Requesting Support
Both spouses must file an Income and Expense Declaration (Form FL-150) with the court. The form requires detailed entries on every category of income, monthly expenses, and debt, and it becomes the factual foundation for any calculation.5California Courts. Income and Expense Declaration Pull together at least two years of federal and state tax returns, recent pay stubs, and documentation of investment income, business profits, and any other earnings before you fill it out.
Take the FL-150 seriously. Understated expenses can lead the court to assume you need less. Understated income tends to come out later when the other side’s attorney digs in, and the fallout can include sanctions.
To ask the court for support, the requesting spouse files a Request for Order (Form FL-300). The filing fee is $60.6Judicial Council of California. Superior Court of California Statewide Civil Fee Schedule If paying the fee would be a hardship, Form FW-001 lets you request a waiver based on low income or receipt of public benefits.7California Courts. Request to Waive Court Fees The clerk assigns a hearing date on filing. The other spouse then has to be served by someone 18 or older who is not a party to the case, and the server completes a proof of service that gets filed with the clerk.8California Courts.

Changing or Ending an Existing Order
Modifying support requires showing a material change in circumstances since the last order. Job loss, a significant raise, retirement, or a serious health change can all qualify. The process starts with a new Request for Order and an updated FL-150 reflecting the changed finances.
Some endings happen on their own. Support terminates automatically, without any motion, when either spouse dies or when the supported spouse remarries, unless the divorce agreement says otherwise in writing.9California Legislative Information. California Code FAM 4337
Cohabitation is a different story. If the supported spouse moves in with a romantic partner, the law creates a rebuttable presumption that their need for support has decreased, and the paying spouse can ask the court to reduce or end payments.10California Legislative Information. California Family Code 4323 The supported spouse can push back with evidence, such as proof they still cover all of their own expenses, but the burden shifts once cohabitation is shown. The couple does not need to hold themselves out as married for the provision to apply.
When Payments Don’t Come
A support order is only as useful as the collection tools behind it. California offers several.
- Earnings assignment. The court orders the employer to deduct support directly from the paying spouse’s paycheck. Under Family Code Section 5230, this assignment is mandatory whenever support is ordered, and the employer must begin withholding within 10 days of receiving the order.11California Legislative Information. California Family Code 5230
- Interest on arrears. Unpaid support accrues interest at 10 percent per year, which adds up quickly.12California Courts. How to Collect Spousal Support
- Contempt. Under Family Code Section 290, a judge can hold a non-paying spouse in contempt, with fines or jail time on the table.13California Legislative Information. California Family Code 290
- Arrears determination. File an Application to Determine Arrearages (Form FL-490) to have the court calculate the exact amount owed and order a monthly repayment schedule on top of ongoing support.12California Courts. How to Collect Spousal Support
Federal garnishment caps apply too. Under the Consumer Credit Protection Act, garnishment for spousal support can reach up to 50 percent of disposable earnings if the paying spouse supports another dependent, or 60 percent if they don’t, with an extra 5 percentage points available once the debt is more than 12 weeks overdue.14Office of the Law Revision Counsel. 15 U.S. Code 1673 – Restriction on Garnishment
Taxes
The federal tax treatment flipped in 2019, and the date your divorce was finalized controls which rules apply to you.
For divorces finalized on or after January 1, 2019, the paying spouse cannot deduct spousal support, and the recipient does not report it as income. The money is tax-neutral.15Internal Revenue Service. Topic No. 452, Alimony and Separate Maintenance
For divorces finalized before January 1, 2019, the old rules still apply: the payer deducts, the recipient reports it as taxable income. If a pre-2019 agreement is later modified and the modification expressly adopts the new tax rules, the payments switch to the post-2018 treatment.15Internal Revenue Service. Topic No. 452, Alimony and Separate Maintenance
Protecting Future Payments
If support is important to your long-term plan, think about what happens if the paying spouse dies before the obligation ends. Family Code Section 4360 gives the court authority to order the paying spouse to maintain a life insurance policy naming the supported spouse as beneficiary, buy an annuity, or set up a trust, so support does not vanish with the payer.16California Legislative Information. California Code FAM 4360 Asking for this protection in the original order is easier than trying to reconstruct it later.
Two Things Easy to Miss
Prenuptial waivers of spousal support have a hard requirement. Under Family Code Section 1612(c), a spousal support provision in a prenup is unenforceable if the spouse giving up support did not have independent legal counsel when they signed.17California Legislative Information. California Family Code 1612 Even with counsel, a court can refuse to enforce the provision if it would be unconscionable at the time of enforcement. Without separate representation at signing, the support waiver is effectively dead no matter what the document says.
Long marriages come with a Social Security benefit many people overlook. If your marriage lasted at least ten years, you may qualify for benefits based on your ex-spouse’s earnings record. You must be at least 62, currently unmarried, and your ex must also be at least 62. If your ex hasn’t yet filed for benefits, you must also have been divorced for at least two continuous years.18Social Security Administration. Who Is Entitled to Wife’s or Husband’s Benefits as a Divorced Spouse Claiming on an ex’s record does not reduce their benefit or affect any new spouse’s eligibility. If you were married for a decade or more, check with the Social Security Administration before assuming spousal support is your only post-divorce income.
