Spousal & ex-spouse Social Security benefits, explained

1. The benefit people forget exists

Social Security isn’t only built on your earnings record. If you’re married, divorced after a long marriage, or widowed, you may be entitled to a benefit based on someone else’s record — and it’s frequently larger than anything your own work history would produce. The trouble is that these benefits don’t announce themselves. Nobody mails you a letter saying “by the way, you can collect on your ex.” You have to know to ask.

There are three flavors, and they’re easy to mix up: the spousal benefit (on a living current spouse), the divorced-spouse benefit (on a living ex), and the survivor benefit (on a deceased spouse or ex). They share DNA but follow different rules on amount, age, and remarriage. Let’s take them in order.

2. How the spousal benefit works

A spousal benefit lets you collect based on your husband’s or wife’s earnings record instead of your own. At your full retirement age, it’s worth up to 50% of the worker’s PIA — their full-retirement benefit. Three details trip people up:

• It’s based on their PIA, not their check. Even if your spouse claimed early and took a reduced benefit, your spousal amount is still figured from their full PIA.
• It doesn’t grow past your FRA. Unlike your own retirement benefit, a spousal benefit earns no delayed retirement credits. Waiting past full retirement age to claim it gains you nothing.
• You get the larger of the two, not both. If your own retirement benefit already exceeds 50% of your spouse’s, you simply receive your own — the spousal benefit only matters when it’s the bigger number.

For currently married couples there’s one more wrinkle: the worker generally must have already filed for their own benefit before you can claim a spousal benefit on their record. (Divorced applicants get an exception — see below.) We dig into the federal-specific mechanics, including CSRS and survivor annuities, in our federal spousal and survivor guide.

3. The ex-spouse rules (the 10-year test)

This is the part most people never hear: divorce does not erase your claim. If your marriage lasted long enough, you can collect a divorced-spouse benefit on your former husband’s or wife’s record. The gatekeeper is the 10-year rule. To qualify, all of the following must be true:

Meet those and you can receive up to 50% of your ex’s PIA, exactly like a current spouse. And here’s the reassuring part: your claim is completely invisible to them. It doesn’t reduce their benefit, doesn’t touch their current spouse’s benefit, and your ex is never notified. Their remarriage is irrelevant to your claim.

4. The two-year rule and other myths

The single most common myth is that you have to wait for your ex to file first. For current spouses that’s true; for divorced spouses there’s an escape hatch. If you have been divorced for at least two years and your ex is at least 62, you can claim on their record even if they haven’t filed — you’re treated as “independently entitled.” You don’t need their cooperation, their permission, or even their current address.

A few more facts that surprise people:

• Multiple long marriages? If you were married 10-plus years more than once, you can claim on whichever ex’s record produces the largest benefit.
• Their new spouse doesn’t crowd you out. You and your ex’s current spouse can both collect on the same record at the same time.
• Remarriage timing matters — for you. Remarry, and you generally lose the divorced-spouse benefit (you’d look to the new spouse’s record). If that later marriage ends, eligibility on the original ex can be restored.

5. Survivor benefits: up to 100%

When a spouse or qualifying ex-spouse dies, the spousal benefit converts to something far more generous: a survivor benefit worth up to 100% of what the deceased was receiving or was entitled to. This is the protection that makes a higher earner’s decision to delay so valuable — the bigger benefit they locked in by waiting becomes the floor their survivor can step into.

Survivor rules differ from spousal rules in ways worth memorizing:

That last row is the strategy gem. Survivor benefits are exempt from deemed filing, so a widow or widower can claim a reduced survivor benefit at 60, let their own retirement benefit keep growing with delayed credits, and switch to it at 70 if it ends up larger. We cover the tax side of this transition — the so-called widow’s penalty — in our dispatch on survivor taxes and the broader first-year-after-losing-a-spouse guide.

6. Estimate your benefit

Enter your own full-retirement benefit (your PIA) and your spouse’s or ex’s, and the estimator shows what you could receive in each role: on your own record, as a spouse (up to 50%), and as a survivor (up to 100%). The amounts shown are at full retirement age.

Simplified estimate at full retirement age. Claiming before FRA reduces the spousal and survivor amounts; survivor benefits start as early as 60. Ex-spouse claims require a marriage of at least 10 years. This is an educational tool, not an official SSA quote.

7. GPO repeal: a federal game-changer

For federal retirees, one change rewrote the math entirely. The old Government Pension Offset (GPO) slashed spousal and survivor benefits by two-thirds of any pension earned in work not covered by Social Security — which wiped out these benefits for many CSRS retirees and their widows and widowers.

The Social Security Fairness Act, signed in January 2025, repealed the GPO (and its cousin, the WEP). A CSRS-covered spouse or survivor who was previously offset down to zero may now be entitled to a full spousal or survivor benefit. If you were ever told your government pension disqualified you, that advice is out of date — it’s worth a fresh look. See our coverage in the WEP/GPO repeal, one year later.

8. Claiming-order strategy

Because deemed filing collapses your own and spousal benefits into “the higher one,” the real strategy lives in survivor benefits and in timing. A few principles that consistently pay off:

• The higher earner should consider delaying to 70. It maximizes not just their own check but the survivor benefit their spouse inherits.
• Widows and widowers can split the timeline. Take the survivor benefit first and let your own grow, or vice versa — whichever is smaller now and can grow more.
• Gather your dates before you call. Marriage date, divorce-final date, and any remarriage date decide eligibility under the 10-year, two-year, and age-60 rules. Survivor claims can’t be filed online — use the phone (1-800-772-1213) or a local office.
• Don’t wait past FRA for spousal-only benefits. They don’t grow after 67.
