How long you have to pay alimony in California depends almost entirely on how long the marriage lasted. If the marriage was under ten years, support usually runs for about half the length of the marriage. If it was ten years or more, the court typically sets no end date at all, and the obligation continues until a judge changes it or one of a few automatic events cuts it off.
Short-Term Marriages Under Ten Years
For a marriage that lasted less than ten years, California courts follow a general benchmark: support should last about half the length of the marriage. A six-year marriage typically produces a support order lasting around three years. That guideline comes from Family Code Section 4320(l), which tells the court that a “reasonable period of time” for the supported spouse to become self-sufficient is generally half the length of the marriage.1California Legislative Information.

The statute does not lock the court into this formula. A judge can order support for a longer or shorter period based on health problems, a large income gap, the supported spouse’s need for education or job training, or any other factor the judge considers relevant. Half the marriage is a starting point, not a ceiling.
Long-Term Marriages of Ten Years or More
A marriage lasting ten years or more is presumed to be a “marriage of long duration” under Family Code Section 4336. The ten years are measured from the wedding date to the date of separation, and the court can weigh periods of separation within the marriage when deciding whether the marriage truly qualifies.2California Legislative Information. California Code FAM 4336 – Spousal Support Upon Dissolution or Legal Separation
When a marriage qualifies as long-duration, the court keeps jurisdiction over spousal support indefinitely rather than setting an end date in the divorce decree. Support continues until a future court order changes or terminates it, or until one of the automatic termination events occurs. This is what people mean when they refer to “permanent alimony” in California, though it is rarely permanent in practice. The paying spouse can go back to court and ask for a reduction or termination by showing that circumstances have changed.2California Legislative Information.

One detail that catches people off guard: the ten-year threshold is not an absolute line. A court can also find that a marriage shorter than ten years was a marriage of long duration based on the specific circumstances. That finding is uncommon, but it is available.
Events That End Support Automatically
Under Family Code Section 4337, spousal support terminates automatically when either spouse dies or when the supported spouse remarries. No court hearing is required for these events to cut off the obligation.3California Legislative Information. California Code FAM 4337 – Termination of Spousal Support
Support also ends on any specific termination date written into the divorce decree. For short-term marriages, this date is usually set at the time of the divorce. For long-term marriages, there is typically no built-in end date, so support continues until an automatic trigger occurs or a court modifies the order.
Cohabitation With a New Partner
Moving in with a new romantic partner does not end support automatically, but it shifts the legal landscape. Family Code Section 4323 creates a presumption that the supported spouse’s financial need has decreased if they are cohabiting with someone. The supported spouse then bears the burden of proving they still need the same level of support. If they cannot, the court can reduce or terminate the payments.4California Legislative Information.

Getting Support Reduced or Ended Early
Spousal support orders are not carved in stone. Either side can ask the court to change the amount or duration by filing a Request for Order (Form FL-300) with the family court. The person requesting the change must show a significant change in circumstances since the last order was made.5California Courts. Ask to Change Your Long-Term Spousal Support Order
Common examples that justify modification include a major drop in the paying spouse’s income, the paying spouse’s retirement, a substantial increase in the supported spouse’s earnings, or a serious health condition affecting either party’s ability to work. When the court revisits the order, it applies the same Section 4320 factors it used to set support in the first place: earning capacity, contributions to the other spouse’s career, ability to pay, the marital standard of living, age and health, domestic violence history, duration of the marriage, and tax consequences.1California Legislative Information.

The Gavron Warning
Under Family Code Section 4330, the court can advise the supported spouse that they are expected to make reasonable efforts toward becoming self-supporting. This advisement is known as a “Gavron warning” after the case that established the practice. The court is not required to issue one, and in long-duration marriages the statute gives the judge discretion to skip it when it would be inappropriate given the circumstances.6California Legislative Information. California Code FAM 4330 – Spousal Support Order
If the court does issue a Gavron warning and the supported spouse makes little effort to find work or improve their earning potential, that failure becomes ammunition for the paying spouse at a future modification hearing. Ignoring one is one of the fastest ways to see a support order reduced.
Vocational Evaluations
In modification disputes, either side can request a vocational evaluation. A vocational expert reviews the supported spouse’s work history, skills, education, and the local job market to estimate what that person could realistically earn. If the evaluation shows the supported spouse is capable of earning substantially more than they currently make, it provides concrete evidence for reducing or terminating support. Courts sometimes order evaluations on their own when the supported spouse claims an inability to work but the record is thin.
Step-Down Orders
Rather than cutting support off abruptly, California courts sometimes issue step-down orders that gradually reduce the monthly payment over time. A court might order $3,000 per month for the first two years, $2,000 for the next two, and $1,000 for the final year. The court does not need to find a separate change of circumstances at each reduction point, but it must clearly state on the record why it is phasing support down rather than setting a single amount.
When a Prenup Limits Support
A prenuptial agreement can limit or waive spousal support entirely, but California imposes strict conditions. Under Family Code Section 1612, a spousal support provision in a prenup is unenforceable if the spouse giving up the right to support did not have their own independent attorney when they signed. Even with independent counsel, the provision is unenforceable if it would be unconscionable at the time someone tries to enforce it.7California Legislative Information. California Code Family Code FAM 1612 – Premarital Agreements
A prenuptial waiver that seemed fair when both spouses were working professionals can become unenforceable years later if one spouse left the workforce to raise children and would face serious hardship without support. Courts look at the circumstances at the time of enforcement, not just at the time of signing.
Temporary Support During the Divorce
Temporary support is a separate track and does not count toward the duration of long-term alimony. Before the divorce is finalized, the court can order temporary spousal support to keep things stable while the case is pending. Judges typically calculate temporary support using a computer program called DissoMaster, which applies a rough formula based on each spouse’s net income. Temporary support ends automatically when the court issues its final divorce judgment and replaces it with a long-term support order or no order at all.
Protecting Support Against the Payer’s Death
Because support terminates when the paying spouse dies, the supported spouse can be left with nothing if that happens unexpectedly. Family Code Section 4360 gives the court authority to order the paying spouse to maintain a life insurance policy naming the supported spouse as beneficiary, or to set up a trust or annuity, so the supported spouse is not cut off if the payer dies before the obligation would otherwise end.8California Legislative Information.
