California alimony has no set end date — it depends on the length of your marriage and what the judge orders

California law does not have a formula that automatically ends alimony after a certain number of years. Instead, the court looks at how long you were married and sets a duration based on that. For marriages under 10 years, alimony often lasts half the length of the marriage. For marriages of 10 years or longer, the court may order alimony to continue indefinitely — meaning it does not end unless something changes.

The judge has broad power to set any duration they think is fair. They can order alimony to end on a specific date, when a certain event happens (like one spouse turning 65), or never. The length is not automatic, and two similar divorces can result in very different alimony orders.

Key Takeaways

  • Marriages under 10 years typically result in alimony lasting half the marriage length, though judges can order longer or shorter periods.
  • Marriages of 10 years or more may result in indefinite alimony, which continues until the court changes the order or a triggering event occurs.
  • The judge considers factors like each spouse's earning ability, age, health, and standard of living during the marriage when deciding duration.
  • Alimony can end early if the receiving spouse remarries, either spouse dies, or the paying spouse retires and income drops significantly.
  • You can ask the court to change an alimony order if your circumstances change substantially — job loss, serious illness, or major income shift.

How the 10-year marriage rule works

California Family Code Section 4336 treats marriages under 10 years differently from longer marriages. For a marriage that lasted, say, 6 years, the court often orders alimony for about 3 years. For an 8-year marriage, alimony might last 4 years. This is a guideline, not a rule — judges can deviate from it if they have good reason.

The 10-year threshold matters because it shifts the default assumption. Below 10 years, the court assumes alimony should be temporary. At or above 10 years, the court assumes alimony may be permanent. A marriage of exactly 10 years sits in a gray zone; some judges treat it as permanent, others as temporary. This is one reason why two divorces that look similar can produce different orders.

The length of the marriage is measured from the date you married to the date you separated, not the date the divorce was finalized. If you separated after 9 years and 11 months of marriage, you are still under the 10-year line.

What "indefinite" alimony actually means

Indefinite alimony does not mean forever in practice. It means the order does not have a built-in end date. The alimony continues until one of several things happens: the receiving spouse remarries, either spouse dies, the paying spouse retires and income drops, or the court changes the order because circumstances have changed substantially.

A judge might order indefinite alimony for a 15-year marriage where one spouse stayed home to raise children and has limited earning power. That spouse receives alimony with no expiration date written into the order. But if that spouse later remarries, the alimony stops automatically under California law. If the paying spouse loses their job and income drops by 40 percent, they can ask the court to reduce or end the alimony.

Indefinite does not mean unchangeable. Either spouse can return to court and ask for a modification if their situation shifts significantly.

Factors the judge considers when setting duration

California law lists specific factors judges must weigh. These include the age and health of each spouse, their earning ability and job skills, the standard of living during the marriage, the length of the marriage, and whether one spouse sacrificed education or career for the family. A judge also looks at whether the receiving spouse can become self-supporting and, if so, how long that will realistically take.

A 55-year-old who left the workforce 20 years ago to raise children will likely receive longer alimony than a 35-year-old with current job skills and a college degree. A spouse who has a serious health condition may receive longer alimony because they cannot work full-time. A marriage where one spouse put the other through professional school may result in longer alimony to balance that sacrifice.

The judge writes these reasons in the order. If you disagree with the duration, you can appeal, but appeals are difficult and expensive. The judge's reasoning matters because it shows what would need to change for you to ask for a modification later.

When alimony ends automatically

Alimony stops automatically if the receiving spouse remarries. This is true whether the alimony was ordered for a set number of years or indefinitely. Remarriage triggers termination under California Family Code Section 4337, even if the new marriage ends quickly.

Alimony also ends if either spouse dies. If the paying spouse dies, the receiving spouse's claim against the estate is limited and depends on what the divorce order said. If the receiving spouse dies, alimony obviously stops.

Some orders end alimony when the receiving spouse reaches a certain age, often 65 or 67. Others end alimony if the receiving spouse cohabits with a romantic partner for a set period (often 6 months), though cohabitation is harder to prove than remarriage and requires the paying spouse to ask the court to modify the order.

How to ask the court to change the duration

If your circumstances change substantially after the divorce, you can ask the court to modify the alimony order. Substantial change means something significant — a job loss, a major illness, a large drop in income, or retirement. A small raise or a minor change in expenses usually does not may have access to.

To modify alimony, you file a request with the court in the county where the original divorce was filed. You must show the court what has changed and why the current order is no longer fair. The judge then decides whether to change the duration, the amount, or both. If the receiving spouse is doing well financially and no longer needs alimony, the court may end it early. If the paying spouse's income drops sharply, the court may reduce it or extend the duration if the receiving spouse still cannot support themselves.

Modification requests can take several months and cost money in court fees and attorney time. The court will not modify an order straightforward because you want a different outcome. The change in circumstances has to be real and substantial enough that the original order would not be fair today.

Temporary alimony during the divorce vs. permanent alimony after

California courts can order two types of alimony: temporary alimony while the divorce is happening, and alimony after the divorce is final. Temporary alimony (called "spousal support" during the case) is meant to help the lower-earning spouse pay bills and attorney fees while the case is pending. It usually lasts only until the judge signs the final divorce order.

The alimony ordered in the final divorce judgment is what lasts for years or indefinitely. This is the order that follows the 10-year rule and the factors listed above. Temporary alimony and permanent alimony are separate, and the duration of one does not determine the other.

Some people confuse these two types and think temporary alimony will continue after the divorce. It will not. Once the judge signs the final order, temporary alimony stops and the new alimony order takes effect.

Frequently Asked Questions

Does alimony automatically end after 5 years in California?

No. Alimony does not end automatically after any set number of years unless the judge's order says it does. For a 10-year marriage, the court might order alimony for 5 years, but that is the judge's choice, not a rule. For a 20-year marriage, the court might order indefinite alimony.

What happens to alimony if I lose my job?

You can ask the court to reduce or suspend alimony if you lose your job and your income drops significantly. You must file a modification request and show the court that the job loss was not your fault and that you cannot pay the current amount. The court will not eliminate alimony straightforward because you are unemployed, but it may lower the payment while you search for work.

Can the court extend alimony beyond what was originally ordered?

Yes. If the receiving spouse is still unable to support themselves and the paying spouse's income has increased, the court can extend alimony or increase the amount. Either spouse can ask for a modification if circumstances have changed substantially since the original order.

Does alimony end if the paying spouse retires?

Retirement does not automatically end alimony, but it can trigger a modification. If you retire and your income drops, you can ask the court to reduce or end alimony. The court will look at whether you truly cannot afford it and whether the receiving spouse can support themselves. Voluntary retirement to avoid alimony is viewed skeptically by judges.

What if the receiving spouse is living with someone but not married?

Cohabitation can be grounds to modify or end alimony, but it is not automatic like remarriage. The paying spouse must ask the court to modify the order and prove that the receiving spouse is in a committed relationship and sharing living expenses. The court then decides whether the cohabitation is substantial enough to reduce alimony. This is more complicated than remarriage and requires court involvement.
