A marriage that ended decades ago can still pay a monthly Social Security check. A divorced person who was married at least 10 years can claim a benefit on a former spouse’s earnings record worth up to half that ex’s full benefit, and doing so subtracts nothing from the ex or from anyone the ex later married. The provision is among the most valuable and least understood pieces of the program, because it lets someone with a thin work history of their own draw on a higher-earning former partner, frequently without the ex ever learning the claim was made.
The 10-year rule and the conditions around it
The threshold that unlocks the benefit is the length of the marriage. It must have lasted at least 10 years before the divorce became final, a bright line that pays nothing to a couple who split at nine years and everything to one that reached ten. Beyond the duration test, the person claiming must be at least 62, must currently be unmarried, and the ex-spouse must be entitled to Social Security retirement or disability benefits.
There is a carve-out that surprises many divorced people. If the divorce is at least two years old, the claimant can collect on the ex’s record even before the ex has filed, provided the ex is at least 62 and old enough to qualify. That rule frees a divorced spouse from waiting on a former partner who is delaying a claim, and it removes the awkward need to coordinate with someone the claimant may not have spoken to in years.

Up to half, and how early claiming shrinks it
The headline figure is the ceiling, not a guarantee. A divorced spouse who waits until full retirement age can receive up to 50 percent of the ex’s full benefit amount, calculated from the ex’s benefit at their own full retirement age rather than a reduced or increased figure. Claiming earlier than full retirement age permanently trims the divorced-spouse benefit, the same way early claiming reduces a worker’s own retirement check.
There is also a comparison built into every claim. Social Security does not stack a divorced-spouse benefit on top of a person’s own retirement benefit; it pays the higher of the two. A claimant whose own work record produces a larger check receives that instead, while someone whose own benefit falls short of half the ex’s amount is topped up to the higher figure. The provision matters most, then, for people whose own earnings were low or interrupted, often those who spent years out of the workforce raising a family during a long marriage. For someone in that position, the divorced-spouse benefit can be the difference between a retirement funded largely by a former partner’s decades of earnings and one built on a scattered handful of low-wage years of their own.
Why the claim takes nothing from the ex
The feature that makes the benefit feel almost too good is that it is invisible to the person whose record pays it. A divorced-spouse benefit does not reduce the ex’s own retirement check, does not touch the benefit of the ex’s current spouse, and does not shrink because more than one former spouse is claiming. Each eligible ex from a marriage of 10 or more years can draw independently, and none of them competes with the others for a shared pool.
That independence exists because the divorced-spouse benefit is not carved out of the worker’s benefit at all; it is an additional payment the program makes on top of the record. The distinction is what separates it from the family maximum that caps benefits for a current spouse and children living in one household. A former spouse’s claim sits outside that ceiling, which is why the ex generally has no reason to object and often no way to know.
The benefit does not end at the ex’s death. A surviving divorced spouse from a marriage of at least 10 years can move to a survivor benefit worth as much as 100 percent of what the deceased ex was receiving, a substantial step up from the 50 percent cap that applied while the ex was alive. For a divorced person whose own benefit is small, that survivor provision can become the larger part of their retirement income later in life.
The recurring obstacle is not eligibility but awareness. Social Security will not reach out to a divorced person to point out that a decade-old marriage entitles them to a benefit, and the claim has to be initiated by the person who qualifies. A short marriage, a remarriage that was never dissolved, or simply never asking are the usual reasons the money goes unclaimed, and each of them is a decision a claimant can check against the actual rules rather than assumptions about what a divorce erased.
