A 66-year-old woman divorced 12 years ago after a 14-year marriage has a Social Security benefit of about $1,200 a month at her full retirement age (FRA) of 67. Her ex-husband, the higher earner, receives roughly $3,200 monthly. What she may not realize is that she can claim on his earnings record without his knowledge or cooperation, leaving his check untouched.
This blind spot shows up constantly in retirement forums. Most people on these platforms assume the door closed when the marriage ended, but the divorced-spouse benefit stays intact for years afterward and can be worth thousands of dollars annually.
The rule that changes the math
A divorced spouse can draw on an ex’s earnings record if four conditions are met: the marriage lasted at least 10 years, she is currently unmarried and at least 62, and the ex is at least 62. The ex does not have to have filed for benefits, as long as the divorce finalized two or more years ago. Social Security will not contact him, and his benefit stays exactly the same.
Social Security pays the higher of her own benefit or the ex-spousal benefit, not both. At her FRA of 67, that benefit equals 50% of her ex’s primary insurance amount (PIA), or $1,600 a month against his $3,200. Compared to her own $1,200, that is a gain of $400 per month, or $4,800 a year, for life. One phone call and a single form can raise her income by roughly the cost of a decent used car every year, indexed for inflation.
One important nuance: the spousal benefit is always based on the ex’s PIA, the amount he would receive at his own FRA. If he delayed claiming to age 70 to earn delayed retirement credits, those extra credits do not flow to the divorced-spouse benefit. The cap stays at 50% of his PIA regardless.
Why timing still matters
The 50% figure only applies if she waits until her own FRA. Filing earlier shrinks the spousal portion meaningfully. The Social Security Administration (SSA) reduces the benefit for early claimers, with the divorced-spouse amount falling to roughly 72% of the full spousal benefit at age 62, climbing back to 100% only at FRA. On her $1,600 target, starting at 62 instead of 67 leaves her with roughly $1,140 a month, about $460 short every single month. That gap compounds across a 25-year retirement into a very significant sum.
Cost-of-living adjustments (COLAs) then ride on whichever benefit she collects. The Bureau of Labor Statistics reported in May 2026 that the CPI-U stood at 335.1, up 4.2% from a year earlier. A COLA applied to $1,600 puts meaningfully more money in her pocket than the same rate applied to $1,200, and that difference repeats every year.
How this lands in the rest of her retirement
If her ex dies first, the divorced-spouse benefit converts to a divorced-survivor benefit worth up to 100% of his benefit. That could mean $3,200 a month instead of $1,600. For women who outlive their ex-husbands, this is the long-tail prize of the entire calculation, and it is a reason to think carefully before remarrying. Remarriage before age 60 shuts off the survivor option unless that later relationship also ends.
The extra $4,800 a year can push a retiree across the threshold where Social Security itself becomes taxable. The combined-income formula, which counts half of benefits plus other earnings, starts taxing benefits at $25,000 for a single filer. A higher benefit and a 401(k) withdrawal in the same year can push more income into taxable territory quickly. There is, however, a newer offset worth knowing: the One Big Beautiful Bill Act, signed into law in July 2025, created a temporary $6,000 senior bonus deduction for taxpayers age 65 and older, available through 2028. The deduction phases out above $75,000 in modified adjusted gross income for single filers and applies whether you itemize or take the standard deduction. For retirees close to the Social Security taxation threshold, this deduction can help absorb the income bump from switching to a larger benefit. Model the interaction before pulling the trigger on large IRA distributions.
What to think through before filing
- Confirm eligibility on paper. Pull the divorce decree and marriage certificate. Ten years of marriage is the bright line. Nine years and 11 months gets nothing.
- Get the ex’s benefit estimate. Social Security will share it once you apply, even if he has not filed. If his benefit is close to or below twice yours, the spousal route may not help and your own record wins.
- Wait until full retirement age if you can. Locking in a permanently reduced benefit at 62, when a few more years would mean hundreds more per month for life, is the hardest mistake to undo.
Every divorce file looks different, and interactions with pensions, remarriage history, or a deceased ex can shift the answer entirely. The core point is simply that this benefit exists, it is hers to claim, and ignoring it is the costliest oversight in this scenario.
Editor’s note: This article has been updated to reflect the May 2026 CPI-U reading of 335.1 (up 4.2% year-over-year per the Bureau of Labor Statistics), replacing the earlier March 2026 figure; added the clarification that divorced-spouse benefits are capped at 50% of the ex’s PIA regardless of his delayed retirement credits; and noted the $6,000 senior bonus deduction created by the One Big Beautiful Bill Act (signed July 2025), which is relevant to the Social Security taxation threshold discussion.
