Ex-Spouse Social Security in 2026: The 10-Year Rule, Explained

Plenty of people who qualify for a divorced-spouse benefit never claim it, and the reason is usually a rumour: that claiming on an ex's record takes money out of their cheque, that they have to agree, or that they will find out. None of that is true. Your benefit is paid by the trust fund, not by your former spouse, and the Social Security Administration never contacts them about it.

What is true is that four gates stand in front of it, one of them closes forever the day your divorce is final, and the rules differ from those for a currently married spouse. This describes how the rules work; it is not advice about your own case.

The four gates

Ten years of marriage. Measured to the date the divorce was final, not the date you separated or filed. A marriage that ended at nine years and eleven months qualifies for nothing on that record, permanently — no partial credit, no appeal. It is the highest-stakes date in a divorce already near the line, and it sits alongside the other financial questions settled at the same time.

You are unmarried now. Yours ends it; theirs does not. Your ex can remarry as often as they like and it changes nothing for you, and their current spouse can claim a full spousal benefit on the same record while you do. If you remarry, the divorced-spouse benefit stops while that marriage lasts — and if that later marriage ends by divorce, annulment or death, eligibility on the first record generally returns.

You are 62 or older, and so is your ex. Sixty-two is the floor for the retirement benefit. (Sixty is the floor for the survivor benefit, a different animal — see below.)

Your ex has filed — or you have been divorced two years. A currently married spouse cannot claim until the worker actually files. A divorced spouse can: after two continuous years since the divorce, you can claim on an eligible ex's record whether or not they have filed. On this axis the divorced spouse is better placed than the married one.

Note what is not on the list: their permission, their knowledge, their cooperation, their new spouse's consent. And if more than one of your marriages lasted 10 years, you can claim on whichever record pays the most.

What it actually pays

The ceiling is 50% of your ex's primary insurance amount — their benefit at their full retirement age, not the larger cheque they collect by delaying to 70. Delayed retirement credits are theirs alone and never raise your ceiling.

Take an ex-spouse with a $3,000 full-retirement-age benefit. Half is $1,500, and that is the most this record can ever pay you — swap in their real figure and the ceiling moves with it.

If you have your own work record, you do not get to stack. Since 2016, filing for one benefit is treated as filing for both — deemed filing — and you receive your own benefit plus only the amount by which half of your ex's exceeds it. With your own $1,000 benefit, half of theirs is $1,500, so the excess is $500. Each part is then reduced on its own schedule if you claim early: your own loses 5/9 of 1% a month for the first 36 months and 5/12 of 1% after, while the spousal part loses the steeper 25/36 of 1% and then 5/12 of 1%.

Read the last column carefully, because it inverts the advice everyone hears. If your entire benefit comes from your ex's record, waiting past your full retirement age gains you nothing. Spousal benefits do not earn the 8%-a-year delayed retirement credits. Sixty-seven and seventy pay the identical $1,500, and the three years of waiting are simply gone — about $54,000 of them. Delay pays only when you have a record of your own for the credits to grow on, so which case you are in decides the answer, and the two answers point in opposite directions.

If your own full benefit is $1,500 or more against their $3,000, the excess is zero and their record adds nothing — you are paid on your own. In 2026 the average retirement benefit is around $2,000 a month and the most anyone can receive at full retirement age is a little over $4,000, so a ceiling between $1,000 and $2,000 covers most cases.

Divorced spouse is not divorced survivor

If your ex dies, you move to a different benefit with different rules, and it is usually worth considerably more. This is where most of the confusion in the topic lives.

Four lines matter enough to restate. The survivor benefit starts two years earlier. It pays double the percentage. It inherits the delayed credits your ex bought by waiting, so an ex who delayed to 70 leaves a larger survivor benefit than their bare full-retirement amount. And remarriage at 60 or later does not touch it, which is why that age line exists. The 10-year rule still applies to both.

The switching rule creates the real room to manoeuvre: a divorced survivor may take the reduced survivor benefit at 60 while their own record keeps earning delayed credits to 70, then switch — or the reverse. Deemed filing does not apply between survivor and retirement benefits. Whether the sequence pays is a longevity question, and the break-even arithmetic between claiming ages is the honest way to look at it.

If you were told a government pension would wipe this out

For decades, divorced teachers, police officers, firefighters and state employees with pensions from work outside Social Security were told the Government Pension Offset would cut their spousal or survivor benefit by two-thirds of that pension — usually to zero — and many never applied.

That is no longer the law. The Social Security Fairness Act, signed on 5 January 2025, repealed both the Government Pension Offset and the Windfall Elimination Provision, retroactive to benefits payable for January 2024. Advice given before then that the offset would zero you out is out of date. The same repeal changed the arithmetic for married public-sector households too.

FAQ

Will my ex find out, and does it reduce what they get?

No, on both counts. Social Security does not notify the number holder, and the benefit is paid from the trust fund rather than deducted from their cheque. Their current spouse's benefit is unaffected, and more than one qualifying ex-spouse can claim on the same record at the same time without any of them reducing the others. The only payment that changes is yours.

We were married nine and a half years. Is there any way to qualify?

Not on that record. The rule is measured to the date the divorce became final, with no partial credit, no rounding and no hardship exception. A divorce finalised even a month past the ten-year mark qualifies in full; nine years and eleven months qualifies for nothing. Under it, your options are your own record or another marriage that did last 10 years.

I remarried. Have I lost it forever?

Not necessarily. The divorced-spouse benefit is suspended while you are married to someone else, but if that later marriage ends by divorce, annulment or death, eligibility on the earlier record generally returns. The survivor version is more generous still: a divorced-survivor benefit is unaffected by a remarriage that takes place at age 60 or later (50 if you are disabled). Remarrying before 60 does end it while that marriage lasts.

Should I wait until 70 to claim on my ex's record?

There is nothing to wait for if your benefit is entirely spousal. The spousal ceiling of 50% is reached at your full retirement age and never grows — $1,500 at 67 and $1,500 at 70 on a $3,000 record — so three years of waiting buys nothing. Delay only helps the portion coming from your own earnings record, which grows 8% a year (2/3 of 1% a month) up to 70. In the mixed example above that is worth $240 a month, not $500 — how your cheque splits between the two parts is what decides it.
