A divorced spouse whose marriage lasted at least a decade can collect a Social Security benefit worth up to half of a former partner’s full retirement amount, and doing so takes nothing away from the ex or from anyone the ex later marries. The benefit comes from the same program yet works as an independent entitlement: the former spouse is not asked to consent, receives no notification, and sees no reduction in their own payment. For older Americans who spent years out of the paid workforce raising a family, it is among the largest benefits that routinely goes unclaimed because it sounds too generous to be real.
Ten years of marriage, and why the ex’s check is untouched
The gateway is the length of the marriage. A union must have lasted ten years or more before the divorce became final for a former spouse to qualify on the worker’s record, and a marriage of nine years and eleven months does not count. The applicant must also be at least 62 and, in most cases, currently unmarried. Those thresholds are strict lines rather than guidelines, which is why the exact wedding and divorce dates on file can decide whether a claim is worth thousands of dollars a year or nothing at all.
The payment sits alongside the worker’s own benefit rather than inside it. The agency’s rules on benefits for a divorced spouse confirm that a claim does not change what the former worker receives, and it does not touch a benefit paid to the worker’s current husband or wife. Because the amount is calculated from the worker’s earnings record but funded by the program itself, there is no shared pot for the two households to divide, and nothing the ex can do to block it.
That independence is the feature most applicants misunderstand. Many assume claiming would trigger a fight, or that a bitter ex could refuse permission, when in practice the former spouse never learns a claim was filed. The only party whose record matters for the calculation is the higher earner’s, and the only approval required comes from the agency confirming the marriage met the ten-year test.

Up to half at full retirement age, less if claimed early
The ceiling is one half of the worker’s primary insurance amount, the figure the worker would receive at full retirement age, and that maximum is reached only when the applicant has reached their own full retirement age. Claiming earlier shrinks it permanently. Under the agency’s early-retirement reduction schedule, a divorced-spouse benefit taken at 62 is cut well below the half-share, and the reduction does not reverse once the applicant later reaches full retirement age.
The benefit also does not stack on top of an applicant’s own retirement check. The agency pays the higher of the two amounts, not the sum, so a divorced spouse with a substantial work history of their own may find their own record already pays more than half of the ex’s. The spousal benefit becomes valuable mainly for the partner whose own earnings were low or interrupted, where half of a higher earner’s record clears their own by a meaningful margin.
A simple example shows the range. If a former spouse’s full retirement amount is $2,400 a month, the maximum divorced-spouse benefit is $1,200, payable to an eligible ex who waits until full retirement age. The same person claiming at 62 would lock in roughly $840 for life, a difference of about $4,300 a year that never resets. The timing decision, not the eligibility question, is usually where the real money is won or lost.
The conditions that quietly end or block the benefit
Remarriage is the most common disqualifier. If the divorced spouse remarries, eligibility on the former partner’s record generally ends, though it can be restored if the later marriage itself ends. A separate provision helps applicants whose ex has not yet filed: once a couple has been divorced for at least two years, a qualifying former spouse can claim on the worker’s record even if the worker has not started benefits, provided the worker is at least 62 and otherwise eligible.
The stakes rise further if the former worker dies. A divorced spouse who was married ten years can qualify for a survivor benefit worth up to the full amount the worker was receiving, a larger figure than the living-spouse half-share, and different remarriage rules apply to survivors. That progression means a decision that looks minor at 62 can shape the size of a survivor payment years later, which is why the record of the marriage is worth confirming while the paperwork is still easy to obtain.
The benefit’s obscurity is its costliest feature. Because it draws from an ex-partner’s earnings without reducing them, it violates the intuition that money must come from someone, and so eligible people never ask. The agency does not seek out divorced spouses to enroll them; the claim has to be initiated, with the marriage dates documented.
For a divorced older American with a thin earnings record of their own, the practical question is not whether the benefit exists but when to take it. Waiting to full retirement age buys the full half-share and preserves a larger survivor benefit down the line, while an early claim trades a permanent cut for cash today. The record shows the door is open for a decade-long marriage; the size of what walks through it depends almost entirely on the age at which the claim is filed.
