California uses a formula for temporary alimony, but judges have broad discretion for permanent awards

California does not have a single mandatory formula that applies to all alimony cases. For temporary alimony — support paid during a divorce — most counties use a guideline calculation based on the payor's gross income, the recipient's gross income, and the length of the marriage. For permanent alimony — support after the divorce is final — judges consider the guideline amount as a starting point but can adjust it based on factors specific to your situation. The actual payment depends on which type of alimony you are dealing with and what a judge decides is fair given your circumstances.

Understanding which calculation applies to you matters because temporary and permanent alimony can be very different amounts. Temporary support is meant to keep both spouses stable during the divorce process, which typically lasts one to three years. Permanent support is meant to address longer-term economic imbalances created by the marriage itself — for example, if one spouse left a career to raise children or support the other spouse's education.

Key Takeaways

  • Temporary alimony uses a county-specific formula based on both spouses' gross incomes, while permanent alimony starts with that formula but allows judges to deviate based on thirteen statutory factors.
  • The guideline formula for temporary support is roughly 40% of the higher earner's income minus 50% of the lower earner's income, but the exact percentage varies by county and changes annually.
  • Judges can order alimony to end when the recipient remarries or when a certain date arrives, and can modify it if either spouse's income changes significantly.
  • The length of the marriage affects how long alimony lasts: marriages under ten years typically result in support lasting half the marriage length, while longer marriages may result in indefinite support.
  • You will need to provide recent pay stubs, tax returns, and documentation of any self-employment income to establish what counts as gross income in the calculation.

How the temporary alimony formula works

Most California counties use a guideline calculation for temporary alimony that starts with gross income. Gross income includes wages, self-employment income, rental income, investment income, and some benefits — essentially what you earn before taxes. The formula subtracts the lower earner's income from the higher earner's income, then applies a percentage to that difference. The exact percentage varies by county; some use 40%, others use different rates. The result is the guideline amount of temporary support.

The formula is designed to be quick and predictable. A judge can deviate from it if there is a reason — for example, if one spouse has substantial assets that generate income, or if explore the formula would leave one spouse below the poverty line. But in most uncontested cases, the guideline amount is what gets ordered. The formula recalculates each year because the percentages and income limits adjust annually, so temporary support amounts can change even if neither spouse's income changed.

Temporary alimony ends when the divorce is final, at which point a judge decides whether to order permanent alimony and, if so, at what amount. Some judges use the temporary amount as a baseline for the permanent order; others start fresh and consider the statutory factors. You can ask the court for a statement of decision explaining how the judge calculated the amount, which helps if you later want to modify it.

What judges consider when setting permanent alimony

Once the divorce is final, California law lists thirteen factors a judge must consider when deciding permanent alimony. These include the length of the marriage, each spouse's earning capacity, the standard of living during the marriage, the age and health of each spouse, and whether one spouse supported the other through education or training. A judge can also consider whether one spouse has primary custody of a child, which affects their ability to work.

The length of the marriage is often the most important factor. California has a rough guideline: for marriages lasting less than ten years, permanent alimony typically lasts for half the length of the marriage. For marriages of ten years or more, judges have discretion to order support for an indefinite period, though they are not required to. A marriage of fifteen years might result in alimony lasting seven and a half years; a marriage of twenty years might result in indefinite support, or support lasting ten years, depending on what the judge finds fair.

Judges also look at whether the recipient can become self-supporting through work or retraining. If one spouse left a career to raise children or support the other spouse's education, a judge may order longer-term support to allow that person time to rebuild earning capacity. If both spouses have similar earning potential, the judge may order shorter-term support or none at all. The judge will also consider whether one spouse has health problems that limit their ability to work.

How income is calculated and what counts as gross income

The starting point for any alimony calculation is gross income, which is different from take-home pay. Gross income includes your salary or wages before taxes, self-employment income (business profit after business expenses but before personal taxes), rental income, interest and dividends, and some government benefits. It does not include child support you receive from another relationship, but it does include child support you pay to another person — that amount is subtracted from your gross income before the alimony calculation.

If you are self-employed, you will need to provide tax returns and business records to show what your actual income is. A judge will not accept a claim that you earn less than your tax returns show. If your income fluctuates, a judge may average it over several years. If you recently changed jobs or started a business, you may need to show documentation of your new income to update a support order. Bonuses, commissions, and overtime are typically included in gross income if they are regular or recurring.

Certain income is excluded from the calculation. Means-tested benefits like CalFresh (food information) or CalWORKs (cash information) do not count as income. Social Security retirement benefits are treated differently depending on the situation — a judge may or may not include them. If you receive income from a trust or inheritance, a judge has discretion to include it or exclude it depending on the circumstances. Stock options and deferred compensation may be included if they are vested or likely to be received.

How the length of marriage affects alimony duration

California distinguishes between short-term and long-term marriages because the purpose of alimony changes with time. In a short marriage where both spouses worked, alimony may be brief or nonexistent. In a long marriage where one spouse sacrificed career opportunities, alimony may last indefinitely.

For marriages under ten years, the general rule is that permanent alimony lasts for half the length of the marriage. A five-year marriage might result in two and a half years of support; an eight-year marriage might result in four years. This is not a hard rule — a judge can order more or less — but it is the starting point. The ten-year threshold is measured from the date of marriage to the date of separation, not the date the divorce is finalized.

For marriages of ten years or longer, California law says a judge may order support for an indefinite period. This does not mean support is automatic or permanent; it means the judge has the power to order it without a set end date. The judge still considers all thirteen factors and decides what is fair. Some judges order indefinite support; others order support for a specific number of years even in long marriages. The order can always be modified later if circumstances change, and either spouse can ask the court to terminate support if circumstances warrant it.

Modifying alimony if income or circumstances change

An alimony order is not final forever. Either spouse can ask a court to modify the amount or duration if there has been a significant change in circumstances. A substantial increase or decrease in income is the most common reason. If the payor loses a job, becomes disabled, or retires, they can ask for a reduction. If the recipient gets a significant raise or starts earning substantially more, the payor can ask for a reduction or termination.

Alimony also ends automatically in some situations. If the recipient remarries, alimony terminates — the law assumes the new spouse will contribute to household expenses. If the recipient enters into a domestic partnership, alimony also ends. If the payor dies, alimony ends (though the recipient may have a claim against the estate depending on the circumstances). If the order specifies an end date and that date arrives, support ends unless the recipient asks the court to extend it before the date passes.

To modify an order, you file a request with the court and serve the other spouse. You will need to show documentation of the change — new pay stubs, tax returns, or evidence of job loss. The court will then decide whether the change is substantial enough to warrant a modification and, if so, what the new amount should be. A change of 10% or more in either spouse's income is often considered substantial, but judges have discretion.

What documents you need to prove income

To establish income for an alimony calculation, you will need recent documentation. For W-2 wages, provide the last two years of tax returns and recent pay stubs (usually the last three months). For self-employment income, provide the last two years of tax returns, profit and loss statements, and business bank statements if available. For rental income, provide the lease, proof of payments received, and documentation of expenses. For investment income, provide statements from the investment account.

If your income has changed recently — you started a new job, got a raise, or lost income — bring documentation of the change. A job offer letter, new pay stub, or notice of termination all help establish what your current income actually is. If you claim you cannot work due to health reasons, medical records or a doctor's statement supports that claim. If you are retired, bring Social Security statements or pension documentation.

The other spouse will likely request your tax returns and financial documents through the discovery process, so having them organized and ready saves time. If you hide or misrepresent income, a judge can order you to pay the other spouse's attorney fees and can adjust the alimony amount based on what the judge believes your income actually is. Courts have authority to impute income — that is, to assume you earn more than you claim — if they find you are deliberately underemployed or hiding earnings.

Frequently Asked Questions

Can alimony be ordered if both spouses earned similar amounts during the marriage?

Yes, but it is less common. If both spouses have similar earning capacity and neither sacrificed career opportunities, a judge may order no alimony or only short-term support. However, if one spouse has primary custody of a child and cannot work full-time, or if one spouse is significantly older or in poor health, a judge may still order support even if incomes were similar.

What happens to alimony if the payor gets a significant raise?

The recipient can ask the court to increase alimony if the payor's income increases substantially. You will need to file a modification request and show documentation of the raise. The court will then decide whether the increase is large enough to warrant a change to the support order.

Does alimony end if the recipient starts living with someone new?

Alimony ends if the recipient remarries or enters a domestic partnership. Living with someone without marriage or a domestic partnership does not automatically end alimony, but the payor can ask a court to consider the new living arrangement when deciding whether to modify support.

Can a judge order alimony for a marriage that lasted only two years?

Yes, though it is uncommon. A judge can order alimony in any marriage if the circumstances warrant it — for example, if one spouse became disabled during the marriage or if one spouse supported the other through education. But for a very short marriage where both spouses worked, a judge is more likely to order no alimony or only minimal support.

What if I cannot afford to pay the guideline amount of temporary alimony?

You can ask the judge to deviate from the guideline formula and order a lower amount. You will need to explain why — for example, if you have substantial debt, other child support obligations, or health expenses. Bring documentation of your expenses and obligations to support your request.
