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

California law does not have a single rule for how long you pay or receive alimony. The duration depends on how long you were married, whether the court set a specific end date, and whether circumstances change enough to ask the court to modify the order. For marriages under ten years, courts often set alimony to end after half the marriage length — so a six-year marriage might mean six years of support. For marriages of ten years or longer, the court may order alimony to continue indefinitely, though either spouse can ask the court to end it later if circumstances shift significantly.

The court order itself is the document that controls how long you pay. If your order says alimony ends on a specific date, it ends then unless you go back to court and convince a judge to change it. If your order says alimony continues "until further order of the court," it continues until one of you files a request to modify or terminate it — and the judge agrees. Understanding what your order actually says is the first step to knowing your obligations.

Key Takeaways

  • Marriages under ten years typically result in alimony lasting half the marriage length, though the court has discretion to order longer or shorter periods.
  • Marriages of ten years or more may result in indefinite alimony, but either spouse can petition the court to end it if circumstances change substantially.
  • The specific language in your court order — whether it names an end date or says "until further order" — determines whether alimony automatically stops or requires a court motion to terminate.
  • Retirement, job loss, remarriage of the recipient, or cohabitation of the recipient may give grounds to ask the court to modify or end alimony, but the court is not required to grant the request.
  • Alimony automatically ends if the recipient dies or if the paying spouse dies, regardless of the original order.

How marriage length affects alimony duration

California courts use the length of the marriage as the primary guide for how long alimony should last. A "marriage of ten years or more" is the legal threshold that changes how judges think about duration. The ten years is measured from the date you were married to the date you separated, not the date the divorce was finalized.

For marriages shorter than ten years, the general guideline is that alimony lasts for half the length of the marriage. A four-year marriage might result in two years of alimony; a nine-year marriage might result in four and a half years. However, this is a guideline, not a rule. The judge can order alimony for a shorter or longer period if the circumstances warrant it — for example, if one spouse has a serious health condition or if one spouse sacrificed education or career to support the other.

For marriages of ten years or longer, the law says the court "may" order alimony for an indefinite period. This does not mean it always does. Some judges set a specific end date even for long marriages. Others order indefinite alimony but make clear that either spouse can return to court to ask for modification. The judge's written order is what matters; the general guideline is just a starting point.

What "indefinite alimony" actually means

Indefinite alimony does not mean you pay forever with no possibility of change. It means the original court order did not set an automatic end date. Either spouse can file a motion to modify or terminate the alimony at any time after the order is entered, and the judge will decide whether circumstances have changed enough to warrant a change.

The burden of proof falls on whoever is asking for the change. If you are the paying spouse asking to end indefinite alimony, you typically need to show a substantial change in circumstances — such as retirement, a significant drop in income, or a long-term job loss. If the recipient is asking to extend alimony that was supposed to end, they need to show that the paying spouse's circumstances have improved or that the recipient still needs support.

Remarriage of the recipient automatically terminates alimony in California, even if the original order said indefinite. Cohabitation — living with a new partner in a marriage-like relationship — does not automatically end alimony, but it is grounds for the paying spouse to ask the court to reduce or terminate it. The court will look at whether the cohabitation has reduced the recipient's need for support.

When alimony ends automatically

Alimony ends automatically in only a few situations, regardless of what the court order says. The most common is the death of either spouse. If the paying spouse dies, the obligation to pay alimony ends, though the recipient may have a claim against the paying spouse's estate depending on the will and state law. If the recipient dies, the paying spouse's obligation ends when ready.

Remarriage of the recipient also terminates alimony automatically. The law assumes that a new spouse has a duty to support the recipient, so the original paying spouse's obligation ends. This is true even for indefinite alimony orders. However, the paying spouse must file a motion to terminate and provide proof of the remarriage; alimony does not stop on its own just because the recipient remarried.

If your court order set a specific end date — for example, "alimony terminates on June 30, 2028" — alimony ends on that date without any additional action needed. However, if you are still receiving or paying alimony and that date passes, it is wise to confirm with the other party and your records that payments have stopped, because the court does not send a reminder.

How to ask the court to change or end alimony

To modify or terminate alimony before the end date in your order, you must file a motion with the court that issued the original order. You cannot straightforward stop paying or stop accepting payments. The process begins with a written request that explains what has changed and why you believe the alimony should be modified or ended.

The court will look at whether the change in circumstances is "substantial and continuing." A temporary job loss or a one-time bonus does not usually may have access to. A permanent job loss, retirement, a serious illness, or a significant and lasting change in income does. If you are the recipient asking for an increase or extension, you need to show that your need for support has increased or that the paying spouse's ability to pay has improved substantially.

Both spouses have the right to request a modification. You do not need the other spouse's agreement. If you cannot agree on the new amount or duration, the judge will decide. The process typically involves filing the motion, serving the other spouse, exchanging financial documents, and attending a hearing or settlement conference. The cost and timeline depend on whether the other spouse contests the request.

Retirement and alimony obligations

Retirement is one of the most common reasons someone asks the court to reduce or end alimony. However, reaching retirement age alone does not automatically end the obligation. The court will look at whether your retirement income is sufficient to continue paying, whether you planned for retirement, and whether the recipient still needs support.

If you retire and your income drops significantly, you can ask the court to reduce alimony. If you retire and your income stays the same or increases, the court is unlikely to reduce your obligation. The judge may also consider whether you retired early by choice or whether you had no choice due to health or age. Someone who retires at 62 by choice may have a harder time convincing a judge to reduce alimony than someone forced to retire at 70 due to a medical condition.

The recipient can also ask the court to continue alimony past the original end date if the paying spouse retires and the recipient still cannot support themselves. This is more common in long marriages where one spouse gave up career opportunities to raise children or support the other spouse's career.

Cohabitation and alimony

If the recipient begins living with a new partner in a marriage-like relationship, the paying spouse can ask the court to reduce or end alimony. California law says cohabitation is grounds for modification, but it does not automatically end alimony the way remarriage does. The paying spouse must file a motion and prove that cohabitation has reduced the recipient's need for support.

The court will look at factors such as how long the cohabitation has lasted, whether the couple shares finances, whether they present themselves as a couple, and whether the new partner is contributing to household expenses. A brief dating relationship where the couple does not share finances will not usually result in a modification. A long-term relationship where the couple shares a home and expenses is more likely to result in a reduction or termination of alimony.

The burden is on the paying spouse to prove cohabitation and its effect on the recipient's need for support. The recipient can argue that the new partner is not actually contributing financially or that the cohabitation is temporary. If you believe cohabitation has changed the situation, gather documentation — such as utility bills, lease agreements, or bank statements showing shared expenses — before filing your motion.

Frequently Asked Questions

Does alimony end automatically when I turn 65 or reach full retirement age?

No. Reaching a certain age does not automatically end alimony in California. However, if you retire and your income drops, you can ask the court to reduce or end your alimony obligation. The court will consider your retirement income, whether you chose to retire, and whether the recipient still needs support.

If my ex remarries, does my alimony obligation end when ready?

Alimony terminates when the recipient remarries, but you must file a motion with the court and provide proof of the remarriage. The obligation does not stop on its own. Once you file and the court confirms the remarriage, you can stop paying, and any alimony owed after the remarriage date may be forgiven depending on when you filed the motion.

What happens to alimony if I lose my job?

A job loss is grounds to ask the court to reduce or temporarily suspend alimony, but you must file a motion. The court will look at whether the job loss was involuntary, how long you have been unemployed, and whether you are actively searching for work. A temporary layoff may result in a temporary reduction; a permanent job loss may result in a permanent modification.

Can I ask the court to end alimony early if circumstances have changed?

Yes. Either spouse can file a motion to modify or terminate alimony if there has been a substantial change in circumstances. You must show the court what has changed and why the alimony should be modified. The court is not required to grant your request, but you have the right to ask.

What if my ex stops paying alimony before the end date?

If alimony payments stop and you are may have access to to receive them, you can file a motion for contempt or ask the court to enforce the order. You may also be able to collect back payments plus interest. Contact the court that issued the order or a family law attorney for guidance on enforcement options in your county.
