Spousal support (alimony) in California is not automatic and is not set by a single formula the way child support is. This guide explains the two kinds of spousal support, the factors a court weighs for long-term support, how the length of the marriage matters, how long support lasts, and when it can be changed or ended.

This is general information about California law, not legal advice. Consult a California-licensed family law attorney about your situation.

Temporary vs. long-term support

California recognizes two types. Temporary (pendente lite) support is ordered while the divorce is pending, to maintain the financial status quo until the case ends; most courts calculate it using a local guideline formula (often built into the same software used for child support), which makes temporary support relatively predictable. Long-term (sometimes called "permanent") support is decided at or after judgment and is not based on a formula — the court must weigh the statutory factors in Fam. Code § 4320 and exercise discretion. The shift from a formula-driven temporary number to a discretionary long-term number is one of the most important transitions in a support case.

The distinction matters in practice because the two awards serve different purposes. Temporary support exists only to keep both households afloat and preserve the marital lifestyle while the litigation runs its course; it is not meant to predict the long-term outcome. Many counties use a percentage-of-income formula — a common version takes roughly 40% of the higher earner's net income and subtracts about 50% of the lower earner's net income, then adjusts for any child support already flowing — but the exact local rule varies, and the resulting figure is often higher than the eventual long-term order. A spouse who assumes the temporary number will simply continue after judgment is frequently surprised when the court applies the Section 4320 factors and arrives at a different result.

The Section 4320 factors

For long-term support, the court must consider the factors in Fam. Code § 4320, including:

  • the marital standard of living and each spouse's needs based on it;
  • each spouse's earning capacity, marketable skills, and the time and cost to acquire training or education;
  • the extent to which the supported spouse's present or future earning capacity is impaired by periods of unemployment devoted to domestic duties;
  • the supported spouse's contributions to the other's education, training, career, or license;
  • the supporting spouse's ability to pay;
  • the obligations and assets of each party, including separate property;
  • the duration of the marriage;
  • the age and health of the parties;
  • any documented history of domestic violence;
  • the immediate and specific tax consequences to each party;
  • the balance of hardships; and
  • the goal that the supported spouse become self-supporting within a reasonable period of time.

No single factor controls; the court weighs them together and has broad discretion.

Because the list is long and discretionary, the way these factors are argued often matters more than the factors themselves. The marital standard of living is a recurring battleground: it sets a reference point for the supported spouse's needs, but it is not a guarantee that both spouses can keep living as they did when one household became two. Earning capacity is equally contested — a court can base support on what a spouse could reasonably earn, not just what they currently do earn, and a party who left the workforce may be expected to retrain and re-enter it. Section 4320 also explicitly weighs any documented history of domestic violence, and a separate statute (Fam. Code § 4325) creates a rebuttable presumption against awarding support to a spouse who was criminally convicted of domestic violence against the other spouse. The court must also consider the supported spouse's contributions to the other's career or education — the classic case of a spouse who worked to put the other through professional school.

A worked example

Consider a hypothetical 12-year marriage. One spouse earns $12,000 per month; the other left a career to raise children and now earns nothing. Early in the case, the court sets temporary support using the local guideline calculator, which produces a relatively generous figure aimed at holding the status quo. At judgment, the analysis changes entirely. The court looks at the marital standard of living, the supported spouse's realistic earning capacity after retraining, the years out of the workforce, and the paying spouse's ability to pay. It might order long-term support at a lower monthly figure than the temporary order, set a goal that the supported spouse become self-supporting within a defined period, and — because this is a marriage approaching long-duration territory — retain jurisdiction so the order can be revisited rather than imposing a hard cutoff. The same facts can produce two very different numbers depending on whether the court is preserving the status quo (temporary) or applying the discretionary factors (long-term), which is exactly why the transition catches people off guard.

How the length of the marriage matters

Duration depends heavily on the length of the marriage. For marriages under 10 years, support commonly lasts about half the length of the marriage, and the court typically sets an end date. For a "marriage of long duration" — generally 10 years or more — the court retains jurisdiction over support potentially indefinitely (Fam. Code § 4336), meaning support may continue and be revisited without a fixed termination date. The "half the marriage" guideline is a common practice, not a statute; the court can always order otherwise based on the § 4320 factors. Courts often issue a Gavron warning (named for In re Marriage of Gavron), formally advising the supported spouse that they are expected to become self-supporting.

The 10-year line is widely misunderstood. It does not mean support automatically continues for life after a 10-year marriage; it means the court keeps the power to order or extend support indefinitely rather than being forced to set a termination date. The supported spouse still has to justify continued support under the Section 4320 factors, and the paying spouse can still ask the court to step support down or end it as the recipient becomes self-supporting. Conversely, even in a marriage under 10 years, the "half the marriage" rule of thumb is just a starting point — a court can order a longer or shorter period when the facts warrant.

Step by step: how spousal support is decided

  1. Request support — a spouse asks for temporary support early in the case, often by Request for Order (Form FL-300).
  2. Exchange income and expense information on the Income and Expense Declaration (Form FL-150).
  3. Temporary support is set, usually via a local guideline calculator, to hold the status quo during the case.
  4. At judgment, the court (or the parties' agreement) addresses long-term support by applying the Fam. Code § 4320 factors.
  5. The court sets amount and duration, and may issue a Gavron warning about becoming self-supporting.
  6. Modify or terminate later on a material change in circumstances, unless support was made non-modifiable.

Modifying and terminating support

Long-term spousal support is generally modifiable when there is a material change in circumstances — such as a change in either party's income, the supported spouse's failure to make reasonable efforts toward self-sufficiency, retirement of the paying spouse, or the supported spouse cohabiting with a romantic partner (which creates a rebuttable presumption of decreased need under Fam. Code § 4323). Support ordinarily terminates on the death of either spouse or the remarriage of the supported spouse (Fam. Code § 4337), unless the parties agreed otherwise in writing. Spouses can also agree to make support non-modifiable, which locks in the amount and duration regardless of later changes — a significant decision that should not be made without advice.

Two situations deserve special attention. First, retirement: a paying spouse generally cannot be compelled to keep working past a normal retirement age merely to fund support, and reaching retirement can itself be a changed circumstance justifying a reduction — but the court still examines the actual financial picture, including retirement assets and the recipient's continuing need. Second, cohabitation: once the paying spouse shows the recipient is living with a romantic partner, Section 4323 shifts the burden to the recipient to prove their need has not decreased; cohabitation can justify reducing or ending support, though it does not automatically terminate it the way remarriage does. A party seeking any modification should remember that, like child support, a spousal support change usually dates only to when the request is filed — so a paying spouse whose income drops should file promptly rather than simply stop paying.

Enforcing a support order

A spousal support order is enforceable like any other money judgment. The recipient can obtain an earnings assignment (wage garnishment) that routes payments directly from the paying spouse's employer, and unpaid support — arrears — accrues interest at 10% per year. Other tools include levies on bank accounts and liens on property. A paying spouse who genuinely cannot afford the ordered amount should seek a modification, because ignoring the order lets arrears and interest compound quickly and does nothing to change the underlying obligation.

Taxes

For divorce or separation agreements executed after December 31, 2018, spousal support is not deductible by the paying spouse and is not taxable income to the recipient for federal tax purposes (a change made by the 2017 Tax Cuts and Jobs Act). California state tax treatment differs and may still allow a deduction to the payer and require inclusion by the recipient — a point worth confirming with a tax professional, because it affects the real value of any number on the table.

California statutes behind spousal support

The key authorities are in the Family Code: § 4320 (the factors the court must weigh for long-term support), § 4330 (authority to order support in an amount consistent with those factors), § 4336 (retained jurisdiction over marriages of long duration, generally 10 years or more), § 4323 (rebuttable presumption of reduced need from cohabitation), § 4325 (rebuttable presumption against awarding support to a spouse convicted of domestic violence), and § 4337 (termination on death of either party or remarriage of the supported spouse). Temporary support is governed by a separate line of authority (Fam. Code § 3600) and local guideline practice.

Frequently asked questions

Is spousal support guaranteed in a California divorce?

No. It is not automatic. The court decides whether to award it and how much, based on need, ability to pay, and the Fam. Code § 4320 factors. Temporary support during the case is more formulaic; long-term support is discretionary.

How long will I pay or receive support?

For marriages under 10 years, often about half the marriage length. For marriages of 10 years or more, the court can retain jurisdiction indefinitely (Fam. Code § 4336), with no preset end date.

What's the difference between temporary and long-term support?

Temporary (pendente lite) support is set while the case is pending, usually by a local guideline formula. Long-term support is set at judgment using the discretionary Fam. Code § 4320 factors, not a formula.

Can spousal support be changed later?

Usually yes, on a material change in circumstances — unless the parties agreed to make it non-modifiable. Cohabitation by the supported spouse can reduce support (Fam. Code § 4323).

Does support end if my ex remarries?

Generally yes — spousal support ordinarily terminates upon the supported spouse's remarriage or the death of either party (Fam. Code § 4337), absent a contrary agreement.

Does my spouse's affair affect spousal support?

Generally no. California is a no-fault state, and marital misconduct like adultery is not one of the Section 4320 factors, so it does not increase or reduce support on its own. The main exception is domestic violence, which the court must consider and which can trigger the presumption against support under Fam. Code § 4325.

Can a court make me support my spouse while they refuse to look for work?

The court expects the supported spouse to make reasonable efforts toward self-sufficiency. A Gavron warning formally puts them on notice, and a failure to make reasonable efforts can be a changed circumstance that justifies reducing or terminating support down the road. Earning capacity — what the spouse could reasonably earn — is itself a Section 4320 factor.

When to talk to a California family law attorney

Spousal support is the most discretionary money issue in a California divorce, which makes advocacy and preparation matter. Consider a California family law attorney when the marriage was long (10+ years, where support may continue indefinitely under Fam. Code § 4336); when there is a large income gap or a spouse who left the workforce; when you're being asked to agree to non-modifiable support; when you want to modify or terminate support after a change in income, cohabitation, or retirement; or when the § 4320 factors and tax effects need to be argued. An attorney can model both the temporary and long-term numbers so you understand the real trade-offs before you sign.
