If your marriage lasted at least 10 years, you may qualify for Social Security benefits based on your ex-spouse's work record — up to 50% of their full retirement benefit — without reducing their benefit by a single dollar. The 10-year rule is a strict cutoff, but for those who qualify, it's one of the most valuable and least understood benefits in divorce.

Social Security and divorce is one of those topics that almost everyone gets wrong until they look it up. Many people assume their benefit is only ever based on their own work history. Others assume their ex has to agree, or that claiming somehow takes money away from them. Neither is true. The Social Security Administration has specific rules for divorced spouses — rules that can meaningfully change your retirement picture if you know how to use them.

This article covers both divorced spouse benefits (based on your ex being alive) and survivor benefits (based on your ex's death), plus the remarriage rules, the claiming strategy most people miss, and the one number that makes or breaks eligibility.

What this article covers:
  • The 10-year rule — why it's a hard cutoff and how it's measured
  • Who qualifies for divorced spouse benefits and how much they get
  • The one thing that makes divorced spouse benefits different from spousal benefits
  • How remarriage affects your eligibility — and the age 60 exception
  • Survivor benefits: the rules when your ex-spouse dies
  • The claiming strategy worth knowing about
  • What your ex does — and doesn't — get told

The 10-Year Rule — A Hard Cutoff

The single most important number in Social Security divorce benefits is 10. Your marriage must have lasted at least 10 years — measured from the date of the wedding to the date the divorce was finalized — for you to qualify for benefits based on your ex-spouse's record.

This is a strict cutoff. Nine years and eleven months is not enough. There is no rounding, no discretion, and no exceptions. The SSA measures from the legal marriage date to the legal divorce date. If you were separated for two years before the divorce was finalized, those years count — the clock stops when the divorce decree is entered, not when you stopped living together.

If you're approaching 10 years and considering divorce: The difference between finalizing the divorce one month before or one month after the 10-year mark could affect Social Security eligibility for decades. This is worth discussing with an attorney — not to delay divorce for other reasons, but to make sure you understand the financial stakes of the timing.

Divorced Spouse Benefits: Who Qualifies and How Much

To receive Social Security benefits on your ex-spouse's record, you generally need to meet all of the following:

Your marriage lasted at least 10 years. You're currently unmarried. You're at least 62 years old. Your ex-spouse is entitled to Social Security retirement or disability benefits. And the benefit you'd receive based on your ex's record is higher than what you'd get from your own work history.

That last point is important. You don't get to add your own benefit to the divorced spouse benefit — you receive whichever is higher. If your own retirement benefit would be $1,200 a month and the divorced spouse benefit would be $900, you get $1,200 from your own record. Social Security only pays you one benefit at a time.

How much can you receive?

The maximum divorced spouse benefit is 50% of your ex's Primary Insurance Amount — the benefit they'd receive at their own full retirement age (FRA). If you claim at your own FRA (age 67 for anyone born in 1960 or later), you may receive up to that 50% maximum.

If you claim early — before your own FRA — the divorced spouse benefit is reduced. At age 62, the benefit is approximately 32.5% of your ex's full benefit, increasing gradually for each month you wait up to your FRA. The reduction follows a set schedule, not a simple percentage per year.

The key difference from your own benefit: Your own retirement benefit grows if you delay past your FRA — up to age 70, delayed credits add roughly 8% per year. The divorced spouse benefit does not grow past your FRA. Waiting past 67 to claim on your ex's record adds nothing. The maximum is 50% of their PIA, and that's achieved at your FRA.
Claiming AgeApproximate % of Ex's Full BenefitNotes
62~32.5%Earliest possible; permanent reduction
64~37.5%Gradual increase each month
66~45%Close to maximum
67 (FRA)50%Maximum divorced spouse benefit
68–7050%No additional increase past FRA

Your ex does not need to have already filed for benefits for you to claim — as long as you've been divorced for at least two years and they're eligible to receive Social Security, you may file independently of their decision.

Your Ex Doesn't Find Out — and Their Benefit Isn't Affected

Two things that surprise almost everyone: the SSA does not notify your ex-spouse when you apply for divorced spouse benefits, and your claim has absolutely no effect on the amount they receive. It also doesn't affect any current spouse who may be claiming on their record. Social Security doesn't work like a pie — multiple people can claim on the same worker's record without reducing anyone else's share.

Multiple ex-spouses can each collect: If your ex was married more than once, each former spouse who meets the 10-year rule and other eligibility requirements may independently claim benefits on that record. None of them affect the others.

Remarriage and the Age 60 Exception

Remarrying ends your eligibility for divorced spouse benefits on your ex's record. Once you remarry, Social Security treats you as a current spouse — not a divorced one — and any spousal benefit you might claim would be based on your new spouse's record.

If that second marriage later ends (through divorce or death), you may regain eligibility for benefits on your first ex's record — or claim on the second ex's record, depending on which produces the higher benefit.

The survivor benefit exception

Survivor benefits — the benefits available when your ex-spouse dies — have a more forgiving remarriage rule. If your ex dies, you may still qualify for survivor benefits on their record even if you've since remarried, as long as the remarriage happened at age 60 or later (age 50 if you have a qualifying disability). A remarriage before age 60 blocks survivor benefit eligibility unless that marriage also ends.

Survivor Benefits: When Your Ex-Spouse Dies

If your ex-spouse dies and you were married for at least 10 years, you may qualify for survivor benefits — which are generally larger than divorced spouse benefits and have somewhat different rules.

To qualify, you generally need to be at least 60 years old (or 50 with a qualifying disability), currently unmarried (or remarried at or after age 60), and not receiving a higher Social Security benefit on your own record.

How much are survivor benefits?

Survivor benefits are based on your deceased ex-spouse's actual benefit — not just 50% of it. If they delayed claiming and built up a larger benefit, that larger number flows through to you. At your full retirement age for survivor benefits (which the SSA calculates slightly differently than your retirement FRA), you may receive up to 100% of what your ex was receiving or entitled to receive.

Claiming survivor benefits early reduces the amount. At age 60, the benefit is approximately 71.5% of your ex's full amount. It increases for each month you wait, reaching 100% at your survivor FRA.

The Claiming Strategy Worth Knowing

Here's a strategy many people overlook: if you qualify for divorced spouse benefits and also have your own work record, you don't have to claim both at the same time.

If your ex had a higher earning history than you, your divorced spouse benefit at FRA may be larger than your own benefit at 62. But your own benefit continues to grow with delayed credits until age 70. So one approach — depending on your health, income needs, and other factors — is to claim the divorced spouse benefit at or after 62 while letting your own retirement benefit continue to grow, then switch to your own (now larger) benefit later.

Hypothetical Example — Claiming Strategy

Suppose your own Social Security retirement benefit at FRA (67) would be $1,400 per month, growing to roughly $1,848 at age 70 with delayed credits. Your ex-spouse's PIA is $3,200, giving you a divorced spouse benefit of $1,600 at your FRA.

One option: claim the divorced spouse benefit at 67 ($1,600/month). Another option: claim the divorced spouse benefit at 64 (reduced to roughly $1,420/month), delay your own benefit to 70 ($1,848/month), then switch to your own benefit at 70. Which approach produces more total income over your lifetime depends on when you expect to need the money and how long you live. A fee-only financial planner who specializes in Social Security strategy can run the numbers for your specific situation. This example is illustrative only and not a recommendation.

One important constraint: Current Social Security rules generally require you to claim all available benefits simultaneously — you can't strategically "restrict" your application to only the divorced spouse benefit while leaving your own benefit growing in most cases. The SSA automatically pays you the highest benefit you're entitled to. The strategy above works best when the two benefits are close in value. Consult the SSA or a financial advisor to understand how the rules apply to your specific situation.

How to Apply

You can apply for divorced spouse Social Security benefits through the Social Security Administration directly — online at ssa.gov, by phone, or in person at your local SSA office. You'll need your ex-spouse's Social Security number (or enough identifying information for the SSA to locate their record), your marriage certificate, and your divorce decree.

You don't need your ex's cooperation or their Social Security number to get the process started. The SSA can locate records with a name and approximate date of birth if you don't have the number.
