A divorced spouse can claim Social Security on an ex-partner's record if the marriage lasted at least 10 years — even after remarriage, and without the ex's consent. Enter both work records to see your maximum benefit and the spousal top-up.
| Scenario | Your PIA | Ex PIA | Spousal Max | Your Total |
|---|---|---|---|---|
| Lower earner, high-earning ex | $1,200 | $3,000 | $1,500 | $1,500 |
| Higher earner than ex | $2,000 | $2,000 | $1,000 | $2,000 |
| Born 1958, mid record | $800 | $2,600 | $1,300 | $1,300 |
| Similar records | $1,500 | $4,000 | $2,000 | $2,000 |
When your own PIA exceeds half your ex's PIA, the spousal benefit adds nothing — you simply receive your own larger benefit. The divorced-spouse benefit is a top-up, not an add-on.
Social Security recognizes a marriage of at least 10 years that ended in divorce. If you meet the rule, you can claim a spousal benefit on your ex-partner's record even if they have remarried. Crucially, the ex-spouse is not notified and their own benefit is not reduced — your benefit is paid from the trust fund, not from their check.
Social Security first computes your own retirement benefit. If it is less than half of your ex's PIA at your FRA, you receive your own benefit plus a supplementary amount equal to the difference. If your own benefit is larger, you get no spousal top-up — you simply keep your higher benefit.
Many people expect to receive their own benefit plus 50% of their ex's. Not so: the 50% is a maximum total, and only the shortfall is added. Claiming before FRA reduces the spousal portion further, and delaying past FRA does not increase it — spousal benefits earn no delayed credits.
Ten years of marriage is a bright line with an outsize effect. A couple who divorces after 9 years and 11 months has no divorced-spouse benefit; the same couple one month later has a benefit potentially worth hundreds of dollars a month for life. This is why family-law practitioners sometimes flag the anniversary date during separation discussions, and why the length of the marriage should be documented in the divorce decree. Social Security will verify the marriage dates from its records, but keeping the decree and any supporting documents is prudent.
For a lower-earning or non-working spouse in a long marriage, this benefit can be the difference between a modest and a livable retirement. It is also why the rule cannot be waived by the ex-spouse: it exists to protect a spouse whose earning capacity was suppressed during the marriage, and Congress intentionally made it independent of the ex's consent or even awareness.
Do not confuse the two. A divorced-spouse benefit is up to 50% of the ex's PIA while the ex is alive — a top-up during the claimant's lifetime. A divorced-survivor benefit comes into play when the ex-spouse dies and can be up to 100% of what the ex was receiving, with a lower qualifying threshold (marriage of 10 years for survivors too, but the survivor can claim as early as 60). If an ex-spouse passes away, the survivor benefit is often substantially larger, and remarriage after 60 does not disqualify it. A financial plan for a divorced retiree should consider both.
⚠️ Important: This calculator estimates a divorced-spouse (ex-spouse) Social Security benefit at full retirement age using each party's Primary Insurance Amount. It does not model early-claiming reductions, survivor benefits, the family maximum, taxes on benefits, or the 2-year divorce requirement when the ex has not claimed. Social Security's rules are detailed — confirm your actual benefit at ssa.gov or with a benefits advisor.
