California alimony duration depends on how long you were married and whether a judge sets a specific end date

In California, there is no single answer to how long alimony lasts. The length depends on the length of your marriage, whether you have a written agreement, and what a judge decides if you go to court. For marriages under 10 years, California law suggests alimony should last half the length of the marriage — so a 6-year marriage might have 3 years of alimony. For marriages of 10 years or longer, a judge can order alimony to continue indefinitely, though either spouse can ask the court to end it later.

The key word is "suggests." California Family Code Section 4320 lists factors a judge must consider, but judges have broad discretion. A marriage of exactly 10 years might result in 5 years of alimony in one case and indefinite alimony in another, depending on the judge's reasoning. If you and your spouse reach a settlement agreement, you can agree to any duration you both accept — shorter, longer, or no alimony at all.

Key Takeaways

  • Marriages under 10 years typically result in alimony lasting half the marriage length, though this is a guideline, not a rule.
  • Marriages of 10 years or longer can result in indefinite alimony, meaning it continues until a judge changes the order or one spouse dies.
  • Judges consider income, age, health, custody arrangements, and earning capacity when setting duration, not just marriage length alone.
  • Either spouse can ask the court to modify or end alimony if circumstances change significantly, such as job loss or retirement.
  • A written settlement agreement can set any duration you both agree to, overriding the standard guidelines.

How the 10-year marriage threshold works

California law treats marriages of 10 years or longer differently from shorter marriages. The statute does not define "10 years" with precision — courts count from the date of marriage to the date the divorce petition was filed, and a marriage of 9 years and 11 months is generally treated as under 10 years.

For marriages under 10 years, Family Code Section 4320 suggests that alimony duration should be "one half the length of the marriage." A 4-year marriage might result in 2 years of alimony; an 8-year marriage might result in 4 years. This is not a hard rule — judges can order longer or shorter durations based on the factors in Section 4320 — but it is the starting point many judges use.

For marriages of 10 years or longer, the statute does not set a suggested duration. A judge can order alimony to last indefinitely, meaning it continues until the paying spouse retires, either spouse dies, or the receiving spouse remarries. The paying spouse can ask the court to reconsider the duration later if circumstances change, but the initial order may have no end date written into it.

What judges consider when setting duration

Marriage length is only one factor. California Family Code Section 4320 requires judges to consider the age and health of each spouse, the standard of living during the marriage, the earning capacity of each spouse, whether one spouse sacrificed education or career for the family, the ability of the paying spouse to pay, and the needs of the receiving spouse. A 15-year marriage in which one spouse stayed home to raise children and is now 58 years old with no recent work history may result in longer or indefinite alimony than a 15-year marriage in which both spouses worked throughout and have similar earning capacity.

The judge also considers whether the receiving spouse can become self-supporting through work, education, or retraining. If a spouse is young, healthy, and has marketable skills, a judge may order a shorter duration or include a "step-down" arrangement in which alimony decreases over time. If a spouse is older, in poor health, or has been out of the workforce for decades, a judge may order longer alimony or indefinite support.

Custody of minor children also affects duration. If the receiving spouse has primary custody and cannot work full-time because of childcare responsibilities, the judge may order longer alimony. Once the youngest child reaches a certain age or graduates high school, the duration may be reconsidered.

Indefinite alimony and how it can end

Indefinite alimony does not mean alimony for life in all cases. It means the order does not have a built-in end date. Either spouse can ask the court to modify or terminate the alimony order if there is a significant change in circumstances. Common reasons include the paying spouse's retirement, a substantial drop in income, the receiving spouse's remarriage, or the receiving spouse's cohabitation with a new partner (though cohabitation alone does not automatically end alimony in California).

If the paying spouse retires, they can petition the court to reduce or end alimony based on reduced income. The court will not automatically grant the request — the judge will consider whether the retirement was voluntary, whether the paying spouse has other assets, and whether the receiving spouse can meet their needs. A spouse who retires at 65 after 30 years of work has a stronger case than a spouse who retires at 50 by choice.

If the receiving spouse remarries, alimony terminates automatically in California. If the receiving spouse cohabits with a new partner in a marriage-like relationship, the paying spouse can ask the court to reduce or end alimony, but the court must find that the cohabitation has actually reduced the receiving spouse's need for support.

If either spouse dies, alimony ends. The paying spouse's estate does not owe future alimony payments, and the receiving spouse loses the income stream.

Temporary alimony during the divorce process

Before a final divorce judgment, a judge can order temporary alimony to help the lower-earning spouse pay bills during the case. Temporary alimony is set using a different standard than permanent alimony — California courts often use a formula based on the difference in gross monthly income. Temporary alimony ends when the final divorce judgment is entered, and the judge then sets the duration of permanent alimony based on the factors in Family Code Section 4320.

Temporary alimony can last anywhere from a few months to several years, depending on how long the divorce case takes. Some cases settle quickly; others go to trial and take years. Once the final judgment is signed, temporary alimony stops and permanent alimony (if ordered) begins.

Settlement agreements and custom durations

If you and your spouse reach a written settlement agreement, you can agree to any alimony duration you both accept. You might agree to alimony for 3 years, 10 years, indefinitely, or no alimony at all. You can also build in step-downs, in which alimony decreases at certain milestones (such as when the youngest child turns 18 or when the paying spouse reaches retirement age). A settlement agreement must be signed by both spouses and approved by the judge, but judges rarely reject an agreement both parties have freely chosen.

A settlement agreement can also include language about what happens if circumstances change. For example, you might agree that alimony will end if the receiving spouse remarries, or that the paying spouse can ask for a modification if they lose their job. These provisions give both spouses clarity and may reduce future disputes.

Modifying or ending alimony after the divorce

Either spouse can ask the court to change the alimony order after the divorce is final, but only if there has been a significant change in circumstances. A small change in income usually is not enough; the change must be substantial and not anticipated when the order was made. Examples include job loss, serious illness, a major promotion, or retirement.

The spouse asking for the change must file a motion with the court and serve the other spouse. The court will hold a hearing and decide whether the change in circumstances is real and substantial enough to justify modifying the order. If the judge agrees, they may reduce the amount, shorten the duration, or end alimony entirely. If the judge disagrees, the order stays the same.

If the original order has a specific end date (such as "alimony ends on December 31, 2030"), alimony automatically terminates on that date unless the paying spouse asks for an extension before the date arrives and the judge agrees to extend it. If the order says "indefinite," alimony continues until one of the events listed above occurs or the court modifies the order.

Frequently Asked Questions

What happens to alimony if I remarry?

If you are the receiving spouse and you remarry, alimony terminates automatically in California. You do not need to ask the court to end it — it stops on its own. If you are the paying spouse and you remarry, your alimony obligation does not change unless you ask the court to modify it based on changed circumstances.

Can alimony last longer than the marriage itself?

Yes. For marriages of 10 years or longer, a judge can order indefinite alimony, which may last decades. For shorter marriages, the guideline is half the marriage length, but judges can order longer durations if the factors in Family Code Section 4320 support it — for example, if one spouse is disabled or significantly older and cannot work.

What if my spouse retires before alimony ends?

Your spouse can ask the court to reduce or end alimony based on retirement income. The judge will consider the spouse's age, health, assets, and whether the retirement was voluntary. Retirement does not automatically end alimony, but it is a common reason the court will modify an order.

Does cohabitation end alimony in California?

Cohabitation does not automatically end alimony, but the paying spouse can ask the court to reduce or end it. The judge must find that the receiving spouse's cohabitation with a new partner has actually reduced their need for support. straightforward living with someone is not enough — the court looks at whether finances are shared and whether the relationship is marriage-like.

Can we agree to a different alimony duration than what the law suggests?

Yes. If you and your spouse reach a settlement agreement, you can agree to any duration you both accept, shorter or longer than the statutory guideline. The agreement must be in writing, signed by both spouses, and approved by the judge, but judges rarely reject an agreement both parties have freely chosen.
