When a California judge sets permanent spousal support, there is no formula and no calculator. Family Code Section 4320 lists the factors the court must consider, and the judge works through each one, weighs the evidence, and arrives at an amount and duration. The California Family Code 4320 spousal support factors cover the marital standard of living, each spouse’s earning capacity and assets, contributions to the other spouse’s career, the length of the marriage, age and health, documented domestic violence, tax consequences, the balance of hardships, and a catch-all for anything else the court finds just and equitable.1California Legislative Information. California Code Family Code 4320 Judges have broad discretion in how they balance those factors, so understanding what the court looks at gives both spouses a realistic picture of what to expect.
One boundary before going further. Section 4320 governs permanent support, ordered once the divorce is final. Temporary support, paid while the case is pending, follows a simpler standard focused on need and ability to pay, and courts routinely use a guideline calculator to set it.2California Legislative Information. California Code FAM 3600 That calculator is off-limits for permanent support, and case law prohibits using it. A temporary order is not a preview of the final award.
The Marital Standard of Living
The marital standard of living is the benchmark against which the court measures everything else. It refers to the lifestyle the spouses shared during the marriage: housing, transportation, travel, dining, discretionary spending. The court evaluates each spouse’s financial needs in light of that standard, and reviews the assets and obligations of each party, including separate property.1California Legislative Information. California Code Family Code 4320
A spouse who kept a substantial inheritance as separate property, or who has significantly more retirement savings, will see that weighed in the analysis. The goal is not to guarantee both spouses live identically after the divorce. It is to keep one spouse from shouldering a disproportionate share of the financial fallout while the other lives comfortably.
Earning Capacity and the Path to Self-Sufficiency
The court examines whether each spouse can earn enough to sustain the marital standard of living on their own. For the supported spouse, that means looking at marketable skills, what jobs exist for those skills, and how much time and money retraining or additional education would take.1California Legislative Information. California Code Family Code 4320 A spouse who left the workforce for a decade to raise children is evaluated differently than one who kept working throughout the marriage.
Section 4320 explicitly recognizes that time spent on domestic duties during the marriage can damage future earning power. If one spouse stepped away from a career to manage the household, the court treats that gap as a factor favoring support, not as evidence of lack of ambition.1California Legislative Information. California Code Family Code 4320
The Self-Sufficiency Timeline
The statute states a clear policy goal: the supported spouse should become self-supporting within a reasonable period. For marriages that do not qualify as long-duration (generally under ten years), a reasonable period is typically half the length of the marriage. A six-year marriage, for example, points toward roughly three years of support.3California Legislative Information. California Code FAM 4320 The court can still order a longer or shorter period based on the other factors.
The Gavron Warning
Along with support, the court can issue a Gavron warning, a formal notice that the supported spouse is expected to make reasonable efforts to become self-supporting. The warning sets no hard deadline, but it creates a legal foundation for the paying spouse to later argue for a reduction or termination if the recipient has not made genuine efforts toward financial independence. In long-duration marriages, the court can decide the warning is inappropriate and skip it.
Ability of the Paying Spouse to Pay
Support is not just about need. It is also about capacity. The court evaluates the supporting spouse’s earning capacity, income from all sources earned and unearned, assets, and their own standard of living. A court will not order support that leaves the paying spouse unable to meet their own reasonable expenses. This factor also intersects with custody: the court considers whether the supported spouse can work without negatively affecting the children in their care.1California Legislative Information. California Code Family Code 4320
Contributions to the Other Spouse’s Career
If one spouse helped the other earn a degree, professional license, or career advancement, the court weighs that contribution. The classic scenario is one spouse working to put the other through medical school or law school, but the factor applies broadly to any situation where one partner’s career progress depended on the other’s sacrifices.1California Legislative Information. California Code Family Code 4320
This factor sits alongside, but separate from, the community property reimbursement rules for educational contributions. Even if a spouse already received reimbursement for tuition through the property division, the court can still consider the broader career investment when deciding support. A spouse who deferred their own professional growth to advance the other’s career should not have that sacrifice ignored just because the tuition got reimbursed.
Marriage Duration, Age, and Health
The length of the marriage is one of the most consequential factors. California law creates a presumption that a marriage of ten or more years, measured from the wedding date to the date of separation, is a marriage of long duration. For long-duration marriages, the court retains jurisdiction over spousal support indefinitely, meaning there is no automatic end date. The court can still terminate support later if circumstances change, but the default is open-ended jurisdiction.4California Legislative Information. California Code Family Code 4336
Two nuances matter here. The court can consider periods of separation during the marriage when deciding whether it truly qualifies as long-duration, and it can also find that a marriage shorter than ten years qualifies based on the circumstances.4California Legislative Information. California Code Family Code 4336 The ten-year mark is a presumption, not a bright line.
Age and health are weighed for practical reasons. An older spouse or one with chronic health problems that limit their ability to work will generally need more support for a longer period. A 60-year-old with limited work history faces a fundamentally different job market than a 35-year-old in good health.1California Legislative Information. California Code Family Code 4320
Domestic Violence
The court must review all documented evidence of domestic violence between the spouses or against either spouse’s child. That includes protective orders issued after a hearing, no-contest pleas to criminal charges, findings of domestic violence made during the divorce proceedings, and the emotional distress caused by the abuse.1California Legislative Information. California Code Family Code 4320
A separate statute, Family Code Section 4325, goes further. When one spouse has a criminal conviction for domestic violence, specifically a misdemeanor conviction or a conviction resulting in probation, entered within five years before the divorce filing or during the proceedings, the law presumes the convicted spouse should not receive any spousal support from the victim. The convicted spouse can try to overcome the presumption, but must do so by a preponderance of the evidence.5California Legislative Information. California Code FAM 4325
Section 4325 also protects the victim’s finances during the divorce. If circumstances warrant, the court orders attorney’s fees paid from community assets so the victim does not have to use separate property to cover the abuser’s legal costs.5California Legislative Information. California Code FAM 4325
Tax Consequences
The court must consider the immediate and specific tax consequences of a support order to each party.1California Legislative Information. California Code Family Code 4320 The tax landscape shifted significantly in recent years, and the current rules affect both spouses’ bottom line.
For federal taxes, the Tax Cuts and Jobs Act eliminated the alimony deduction for divorce agreements executed after 2018. The paying spouse cannot deduct support payments, and the receiving spouse does not report them as income.6Internal Revenue Service. Topic No. 452, Alimony and Separate Maintenance California did not conform to this federal change for years, so state and federal tax treatment diverged. Starting January 1, 2026, California conforms to the federal rule for any new divorce or separation agreement: alimony is neither deductible by the payer nor taxable to the recipient for both state and federal purposes.7Franchise Tax Board. Alimony
Spouses with agreements executed before 2026 need to pay close attention. If a California divorce was finalized between 2019 and 2025, alimony may have been deductible on the California return even though it was not deductible federally. Modifying that agreement after 2025 could change the tax treatment if the modification expressly adopts the new rules.7Franchise Tax Board. Alimony That is the kind of detail that can cost thousands of dollars if overlooked.
Hardships and the Catch-All Factor
The court must balance the hardships each party would face, and it can consider any other factors it considers just and equitable.8California Legislative Information. California Code FAM 4320 These two provisions, Sections 4320(k) and 4320(n), give judges room to address circumstances that do not fit neatly into the other factors. A special-needs child’s care costs, a family business that is difficult to divide, or any other unusual financial reality can be raised under the catch-all. In practice, the hardship-balancing factor is where the court checks that the overall result feels equitable after working through each statutory factor.
After the Order: What Can Change
The 4320 factors determine what the initial permanent support order looks like. Separate statutes govern what happens later. If the supported spouse moves in with a new romantic partner, Family Code Section 4323 creates a rebuttable presumption that their need for support has decreased, and the paying spouse can use that to request a modification.9California Legislative Information. California Code FAM 4323 Under Family Code Section 3651, the court can modify or terminate support at any time when a material change of circumstances justifies it, unless the original agreement specifically states support is non-modifiable.10California Legislative Information. California Code FAM 3651 Those are separate questions from the 4320 analysis, but worth knowing exist, because an initial award is rarely the last word.
