Millions of divorced older Americans quietly leave money on the table because they assume a marriage that ended years ago has nothing to do with their retirement income. Social Security says otherwise. A person who was married for at least a decade and never remarried can draw a monthly check built entirely on a former spouse’s earnings record, and that check can be worth as much as half of what the ex would collect at full retirement age.
The arrangement is one of the least understood corners of the program, in part because it feels counterintuitive. The former spouse pays nothing, loses nothing, and is never told the claim was filed.
Half of an Ex-Spouse’s Full Benefit
The divorced-spouse benefit can reach 50 percent of the former partner’s primary insurance amount, the figure Social Security uses to describe the benefit a worker has earned at full retirement age. According to the Social Security Administration’s guidance for divorced spouses, an eligible claimant can receive that amount even if the ex has since remarried or started a new family. The higher-earning spouse’s own monthly payment stays exactly the same.
There is an important limit built into the math. Social Security does not stack a divorced-spouse benefit on top of a person’s own retirement check. Instead, the agency pays whichever amount is larger. Someone whose own earnings record produces a bigger benefit simply collects that; the divorced-spouse option matters most for people who earned far less than a former spouse, took years out of the workforce, or never built a substantial record of their own. For a lower-earning retiree, the difference can run to several hundred dollars a month for life.

Why the Ex Never Finds Out
The privacy piece surprises people most. When a divorced person files on a former spouse’s record, Social Security does not contact that former spouse, does not ask for permission, and does not reduce their benefit by a single dollar. The agency’s own answer on collecting from a former spouse’s record makes clear that the ex-spouse cannot block the claim and is not informed it was made. A current spouse of the higher earner is likewise unaffected, and more than one former spouse can claim on the same record without any of them reducing the others.
That design exists because the benefit is meant to protect people who built a household around one earner’s career. It is not a penalty on the higher earner, so the program treats it as invisible to them by default.
The Ten-Year Line and the Timing Traps
Eligibility turns on a handful of firm conditions. The marriage must have lasted at least 10 years before the divorce became final, and the person claiming must be currently unmarried. Remarrying generally ends eligibility on a prior spouse’s record, though a later divorce or the new spouse’s death can reopen it. The claimant must be at least 62, and if the divorce is recent, the former spouse either must already be receiving benefits or the couple must have been divorced for at least two years before a claim can be paid.
Timing then decides how much actually arrives. Claiming a divorced-spouse benefit before full retirement age permanently shrinks it, the same way early filing reduces a worker’s own retirement benefit. Waiting until full retirement age delivers the full 50 percent, but there is a wrinkle worth knowing: unlike a person’s own retirement benefit, a divorced-spouse benefit does not grow past full retirement age. Delaying beyond that point earns no extra credits, so there is no reward for putting off this particular claim once full retirement age arrives.
For a retiree weighing options, the practical move is to ask Social Security to compare both benefits directly. The agency calculates the retiree’s own benefit and the divorced-spouse amount and pays the larger figure, but it can only run that comparison if it knows the former marriage lasted long enough to qualify. A decade of marriage that ended long ago is not a footnote in that calculation; it can be the difference between a modest check and a materially larger one, paid every month, entirely out of view of the person whose record made it possible.
