Her Ex-Husband Is Funding Her Retirement and He Has No Idea: Social Security’s 10-Year Divorce Rule Pays From His Record Without Touching His Check or His Mailbox
Quick Read
-
A 10-year marriage entitles divorced spouses to 50% of an ex’s Social Security at full retirement age, and he never gets notified and loses nothing.
-
Deemed filing rules apply to anyone born after January 1, 1954, automatically triggering all eligible benefits at once and ending the grow-to-70 spousal strategy.
-
Delaying a divorced spousal claim past full retirement age pays nothing extra, since delayed credits only apply to your own earnings record.

Many financial professionals are salespeople paid on what they push, not whether you end up wealthier. A fiduciary is the opposite. The SEC legally requires them to put your interests first. Advisor.com’s free matching tool pairs you with vetted fiduciaries from major national firms, all in under three minutes. See who you match with today.
If you were married for at least 10 years and you are now divorced, the Social Security Administration may cut you a monthly check based on your ex-husband’s earnings record. He will not be notified. His benefit will not shrink by a single dollar. His current wife’s benefit will not shrink either. This is the Social Security divorced spouse benefit, and it is one of the most underused provisions in the entire retirement system, largely because eligible people assume they need their ex’s permission or cooperation. You do not.
What the Rule Actually Says
Social Security pays a divorced spouse’s benefit from the federal trust fund, drawn against your ex’s earnings record. It does not reduce his benefit, does not reduce his current spouse’s benefit, and requires no filing, notice, or consent from him. Multiple ex-spouses can each claim on the same record at the same time, as long as each marriage independently cleared the duration requirement. He never sees a letter. He never sees a line item. The money comes from the government.

Where This Lives in the Law
The authority is Section 202(b) and 202(c) of the Social Security Act, implemented through SSA’s Program Operations Manual System (POMS) RS 00202. The agency’s public-facing rules for divorced spouses are published at ssa.gov under “Benefits for a Divorced Spouse.” Every number below traces back there.
Who Qualifies in 2026
To qualify for divorced spouse benefits, you have to check a few boxes. First, your marriage needs to have lasted at least ten full years, counted from the wedding date to the date the divorce was finalized, not when you separated. People have lost out on this by just a few weeks because they moved out early, and the paperwork did not cross the finish line until after the anniversary. Second, you cannot be married right now. If you remarry, the benefit usually ends, though you can get it back if that later marriage ends due to death, divorce, or annulment.
Third, you need to be at least 62. Your ex also has to be entitled to Social Security retirement or disability benefits, but there is a helpful exception. If your divorce was finalized at least two years ago, your ex does not actually have to have filed yet. That two-year rule is the workaround when a bitter ex refuses to claim. Finally, your own retirement benefit, based on your own work history, has to be smaller than what you would get from your ex’s record. Social Security will pay you the higher of the two, but never both stacked together.
How Much You Get
At your own full retirement age, the divorced spouse’s benefit equals 50% of your ex’s primary insurance amount, the technical term for the monthly benefit he would receive at his own full retirement age. Claim earlier, at 62, and that percentage is permanently reduced. Delaying past your full retirement age does not increase a divorced spousal benefit. Delayed retirement credits apply only to your own record and have no effect on a spousal check. Waiting past FRA on this benefit leaves money on the floor.
How to Claim It
-
Gather your marriage certificate and your divorce decree. SSA can often verify the marriage from its own records, but bring both.
-
Apply at ssa.gov or by phone at 1-800-772-1213. You don’t need your ex’s Social Security number if you have his date and place of birth, though the number speeds things up.
-
If you are unsure whether your own benefit or the divorced spousal benefit is larger, apply anyway. The agency calculates both and automatically pays the higher amount.
-
Time your claim against the 2027 COLA, which is currently tracking toward 3.1%, so you understand what your first-year check will look like.
Trap Almost Nobody Sees Coming
There is a rule called deemed filing that trips a lot of people up. If you were born after January 1, 1954, applying for one benefit is treated as applying for all the benefits you are eligible for. That means the old strategy of claiming a spousal check while letting your own benefit grow until age 70 is no longer available for anyone born after that date. You get the higher of the two benefits, and that’s it.
Survivor benefits are a separate program with better terms. If your ex has died, a surviving divorced spouse may qualify for up to 100% of his benefit, starting as early as age 60 (age 50 if disabled), and remarriage after age 60 does not disqualify you. Do not blur the two. Survivor benefits run on their own clock, with rules couples often get wrong, which is why we walked through the whole survivor math in a free guide here. This benefit most often rescues a woman who spent years out of the paid workforce raising children and now has a thin earnings record of her own. It was built for exactly that situation. Claim it.
