The “How Long Do I Pay — or Get Paid?” Hook
Almost everyone facing divorce has heard the “ten-year rule” for alimony — and almost everyone has it slightly wrong. Spousal support duration in California is more nuanced than a single magic number. Ava asked attorney Michael Benavides how long support really lasts.
Ava Asks, Michael Answers — Spousal Support, Plain English
Ava:
Is there really a ten-year rule for alimony?
Michael, Esq.:
There’s a real rule, but it’s widely misunderstood. Under Family Code section 4336, a marriage of ten years or more — measured from the date of marriage to the date of separation — is presumed a “marriage of long duration.” That does not mean support lasts forever; it means the court keeps jurisdiction, the power to revisit support, open-ended.
Ava:
So a long marriage doesn’t guarantee lifetime payments?
Michael, Esq.:
Correct. It means the court doesn’t set a hard cutoff date at the start. Support can still be reduced or ended later if circumstances change — for example, the supported spouse becomes self-supporting or remarries. Retained jurisdiction is about flexibility, not a blank check.
Ava:
What about marriages under ten years?
Michael, Esq.:
For a shorter marriage, courts generally use a rule of thumb that a “reasonable period” of support is about half the length of the marriage. So a six-year marriage might see roughly three years of support — a guideline, not a straitjacket, but a common starting point.
Ava:
How does the judge set the actual amount and length?
Michael, Esq.:
Through Family Code section 4320. It lists the factors the court must weigh — each spouse’s earning capacity, the marital standard of living, the length of the marriage, age and health, contributions to the other’s career or education, and each spouse’s ability to become self-supporting, among others.
Ava:
Is there a formula like child support?
Michael, Esq.:
For temporary support while the case is pending, many courts use a local formula. But for long-term support after judgment, there is no statewide formula — the judge weighs the section 4320 factors. That’s why two similar-looking marriages can end with very different orders.
Ava:
Can support be changed after the divorce is final?
Michael, Esq.:
Usually yes, if it’s modifiable, on a showing of changed circumstances — a job loss, a big raise, retirement, a new supporting relationship. What counts as “changed” is fact-specific, which is exactly where good advice earns its keep.
Ava:
Does behavior during the marriage affect it?
Michael, Esq.:
California is no-fault, so ordinary marital fault doesn’t drive the number. One notable exception: a documented history of domestic violence can weigh against support to an abusive spouse. Beyond that, it’s finances and the section 4320 factors, not blame.
What to Do
The California “ten-year rule” under Family Code section 4336 keeps the court’s power to award support open-ended — it does not lock in lifetime alimony — while shorter marriages often follow the half-the-length guideline, and the amount always turns on the section 4320 factors. Because long-term support has no fixed formula, the details decide the outcome. A free Law Desk consult estimates a realistic range for your marriage and your finances.
