What Is the 10-Year Rule in California Divorces?

Quick answer

The 10-year rule dictates how long a court retains jurisdiction over spousal support. If a marriage lasts 10 years or longer, it is legally considered a 'marriage of long duration.' In these cases, the court cannot automatically set an end date for alimony; jurisdiction remains open indefinitely unless both spouses agree otherwise in writing.

There is perhaps no California divorce law more misunderstood than the "10-year rule."

Many people believe that if you are married for 10 years, you automatically have to pay spousal support for the rest of your life. Others believe that if you are married for 9 years and 11 months, you pay nothing. Neither is true.

The 10-year rule is entirely about the court's jurisdiction — its legal power to make orders about spousal support in the future.

The "Marriage of Long Duration"

Under California Family Code Section 4336, a marriage that lasts 10 years or more is legally classified as a "marriage of long duration."

The 10-year clock is calculated from the exact date of marriage to the exact date of separation. It is not based on when you file for divorce or when it's finalized.

Example: You marry on January 1, 2010. You declare the marriage over on December 1, 2019. You file for divorce in March 2020. Because the date of separation was under 10 years, this is not a marriage of long duration, even though the divorce wasn't filed until year 10.

How the Rule Affects Spousal Support

Marriages Under 10 Years

If your marriage lasted less than 10 years, the general rule of thumb is that spousal support will last for half the length of the marriage. If you were married for 8 years, the judge will typically order support for 4 years and include a specific termination date in the final judgment. On that date, the court's jurisdiction ends — the paying spouse never has to pay another dime.

Marriages Over 10 Years

If your marriage lasted 10 years or more, the judge cannot set an automatic termination date for spousal support. The court must retain jurisdiction indefinitely. Even if the judge orders $0 in support today, the lower-earning spouse could theoretically return to court 15 years from now and ask for support.

Does It Mean "Alimony for Life"?

No. The 10-year rule does not mean the higher-earning spouse must pay alimony forever. It simply means the burden of proof shifts. In a short-term marriage, support ends automatically. In a long-term marriage, the paying spouse must eventually go back to court and prove the receiving spouse should be self-supporting by now.

Judges expect divorced spouses to make reasonable efforts to become self-supporting within a reasonable period. If the receiving spouse refuses to work, the paying spouse can ask the judge to issue a "Gavron Warning" — a formal notice that if they do not find a job, alimony will be cut off.

How to Close the Door Forever

If you are the higher-earning spouse in a 10+ year marriage, leaving the court's jurisdiction open indefinitely is a massive financial risk. There is only one way to close the door: a strict waiver of jurisdiction in your Marital Settlement Agreement.

If you and your spouse negotiate a settlement out of court, you can include specific legal language stating that both parties permanently waive their right to receive spousal support, and that the court's jurisdiction is terminated forever. If both spouses sign and the judge approves it, the 10-year rule is overridden and the door is closed permanently.

Frequently asked questions

What if we were married for 9 years and 6 months?

While the statute explicitly names 10 years as the threshold, Family Code 4336 also states that a judge can declare a marriage of less than 10 years to be a marriage of long duration if the circumstances warrant it. It is rare, but a judge could apply the rule to a 9.5-year marriage.

Does the 10-year rule apply to child support?

No. The 10-year rule applies exclusively to spousal support (alimony). Child support is governed by entirely different laws and always ends when the child turns 18 (or 19 if they are still in high school).

Can alimony end if the receiving spouse gets remarried?

Yes. Regardless of whether you were married for 2 years or 20 years, California law states that spousal support automatically terminates the moment the receiving spouse gets remarried, unless you have a written agreement stating otherwise.
