Can I Collect My Ex's Social Security After Divorce in South Dakota? (2026 Guide)

By Antonio G. Jimenez, Esq. | Florida Bar No. 21022 | Covering South Dakota divorce law

Yes. If your marriage lasted at least 10 years, you are currently unmarried, and you are age 62 or older, you can collect up to 50% of your ex-spouse's full Social Security benefit under 42 U.S.C. § 402(b). South Dakota residents claim through the Social Security Administration, not state court, and your ex-spouse is not notified or affected.

Key Facts: South Dakota Divorce and Social Security

The 10-Year Marriage Rule Explained

Federal law requires a marriage to have lasted at least 10 consecutive years before divorce for a divorced spouse to claim benefits on the ex-spouse's earnings record under 42 U.S.C. § 416(d)(1). If your South Dakota divorce was finalized at 9 years and 11 months, you lose eligibility entirely — there is no partial credit. The clock runs from the date of marriage on your marriage license to the date the circuit court judge signs your divorce decree.

The Social Security Administration calculates the 10 years based on the legal marriage date recorded with the South Dakota Department of Health and the final decree date filed under SDCL § 25-4-45. If you remarry and divorce the same person, the SSA can combine the two marriage periods to reach 10 years, but only if the remarriage occurred in the same calendar year or earlier than the prior divorce's finalization. Couples close to the 10-year mark sometimes delay their South Dakota divorce filing — which takes a minimum of 60 days under SDCL § 25-4-34 — to cross the threshold.

This is the single most important rule in the ex spouse social security divorce analysis. Miss 10 years by one day, and the entire federal benefit disappears. A South Dakota family law attorney can help time your filing strategically, particularly because the state's 60-day waiting period means filing decisions made now affect finalization two months later.

Eligibility Requirements for Divorced Spouse Benefits

To qualify for divorced spouse benefits in 2026, you must meet five specific conditions under 42 U.S.C. § 402(b): the marriage lasted 10+ years, you are currently unmarried, you are age 62 or older, your ex-spouse is entitled to Social Security retirement or disability benefits, and your own retirement benefit (based on your work record) would be less than what you'd receive as a divorced spouse. If all five apply, you can collect up to 50% of your ex's PIA.

The "currently unmarried" rule is strict. If you remarry at any age, you lose access to your first ex-spouse's benefits — unless that later marriage ends in death, divorce, or annulment. However, if you remarry after age 60 (age 50 if disabled), you can still collect survivor benefits from a deceased ex-spouse under 42 U.S.C. § 402(e)(3). South Dakota's equitable distribution rules under SDCL § 25-4-44 do not affect federal Social Security eligibility — these are two completely separate legal systems.

Your ex-spouse does not need to have filed for benefits yet. Under a 2015 rule change, if you've been divorced for at least 2 continuous years and both spouses are 62+, you can claim "independently entitled" divorced spouse benefits even if your ex has not retired. This is critical for social security benefits divorced planning when an ex-spouse delays retirement to accumulate delayed retirement credits.

How Much Can You Collect?

The maximum divorced spouse benefit equals 50% of your ex-spouse's Primary Insurance Amount (PIA) at their full retirement age, not 50% of their current check. For someone born in 1960 or later, full retirement age is 67. If you claim at your own age 62 (the earliest possible), your benefit is reduced to roughly 32.5% of your ex's PIA due to early filing reductions under 20 C.F.R. § 404.410.

In 2026, the average retired worker receives approximately $1,950 per month from Social Security, meaning a typical divorced spouse benefit at full retirement age would be around $975 monthly. High earners whose ex-spouses paid the maximum Social Security tax could see divorced spouse benefits exceeding $1,900 per month. The maximum PIA in 2026 is approximately $3,900 for workers retiring at full retirement age, which would yield a maximum divorced spouse benefit of roughly $1,950.

The SSA automatically pays you the higher of your own retirement benefit or the divorced spouse benefit — not both combined. This is called the "deemed filing" rule under 42 U.S.C. § 402(r). If your own work record produces a $1,400 monthly benefit and the divorced spouse benefit would be $975, you simply receive your $1,400. If the numbers were reversed, you'd receive the $975 divorced spouse benefit. Proper timing can add tens of thousands of dollars over retirement.

Survivor Benefits If Your Ex-Spouse Dies

A divorced surviving spouse can collect up to 100% of a deceased ex-spouse's full Social Security benefit under 42 U.S.C. § 402(e), provided the marriage lasted 10+ years. The minimum claiming age is 60 (or 50 if you are disabled). Unlike regular divorced spouse benefits, survivor benefits are not capped at 50% — you receive the full amount the deceased worker was entitled to.

This makes survivor benefits substantially more valuable than living-ex divorced spouse benefits. For a deceased ex-spouse whose PIA was $2,400, a divorced survivor at full retirement age would receive $2,400 monthly rather than the $1,200 that would apply while the ex was still alive. South Dakota has no state-level interference with these federal survivor benefits — SDCL § 29A-2-802 addresses inheritance rights in probate, but federal Social Security operates independently.

Importantly, remarriage after age 60 does not terminate divorced survivor benefits. A 62-year-old widow who divorced her ex at age 55 (after 12 years of marriage) can remarry at 61 and still collect her deceased ex's Social Security when he dies. This "age 60 remarriage exception" is one of the most overlooked rules in divorced spouse benefits planning and can be worth $200,000+ over a typical retirement.

When to Claim: Timing Strategies

The earliest claiming age for divorced spouse benefits is 62, and the latest is your full retirement age of 66-67. Delaying past full retirement age does not increase divorced spouse benefits — unlike your own retirement benefit, which grows 8% annually until age 70 under delayed retirement credits, divorced spouse benefits are capped at 50% of your ex's PIA. Claiming at 62 reduces the benefit by approximately 35%.

For someone whose ex's PIA is $2,800, the monthly divorced spouse benefit varies dramatically by claiming age: $910 at age 62, $1,120 at age 64, $1,330 at age 66, and $1,400 at full retirement age 67. Over a 20-year retirement, claiming at 67 instead of 62 adds approximately $118,000 in lifetime income. South Dakota residents finalizing divorces in 2026 under SDCL § 25-4-45 should factor Social Security timing into their settlement negotiations.

A common error is claiming divorced spouse benefits at 62 when your own work record would produce a higher benefit at 67. Because of deemed filing, the SSA pays the higher of the two — but early claiming permanently reduces both. Workers born after January 1, 1954 can no longer use the "file and suspend" or "restricted application" strategies that were eliminated by the Bipartisan Budget Act of 2015.

South Dakota Divorce Process and Fees

Filing for divorce in South Dakota costs approximately $95 under SDCL § 16-2-29.5, plus service fees of $50-$150 depending on method, bringing total court costs to roughly $145-$245 (as of April 2026 — verify with your local clerk). The plaintiff must be a South Dakota resident at the time of filing under SDCL § 25-4-30, though there is no minimum duration requirement unlike many states that require 6 or 12 months.

After filing, South Dakota imposes a 60-day waiting period before the court can finalize the divorce under SDCL § 25-4-34. Contested divorces involving property disputes, custody, or alimony typically take 6-12 months. Uncontested divorces where both parties agree on all issues can finalize as soon as day 61. For couples approaching the 10-year Social Security threshold, this timing matters enormously — a divorce filed at 9 years and 10 months cannot finalize before the 10-year mark due to the statutory wait.

South Dakota uses equitable distribution under SDCL § 25-4-44, meaning courts divide marital property fairly but not necessarily equally. Federal Social Security benefits themselves cannot be divided by a state court — the Supreme Court held in Hisquierdo v. Hisquierdo, 439 U.S. 572 (1979) that the Supremacy Clause prevents states from treating Social Security as divisible marital property.

How to Apply for Divorced Spouse Benefits

Apply online at SSA.gov, by phone at 1-800-772-1213, or in person at any Social Security office. South Dakota has SSA field offices in Sioux Falls, Rapid City, Aberdeen, Pierre, and Watertown. You'll need your marriage certificate, divorce decree signed under SDCL § 25-4-45, birth certificate, Social Security number, your ex-spouse's Social Security number (or full legal name and date of birth), and your bank account information for direct deposit.

You do not need your ex-spouse's permission or knowledge. The SSA will not contact your ex-spouse, and your claim has zero effect on their benefit amount or their current spouse's benefits. If you don't know your ex's SSN, the SSA can usually locate their record using name, date of birth, parents' names, and places of prior employment. Process the application at least 3 months before you want benefits to begin — retroactive benefits are capped at 6 months under 20 C.F.R. § 404.621.

If the SSA denies your claim, you have 60 days to request reconsideration, followed by a hearing before an Administrative Law Judge, an Appeals Council review, and finally federal district court review. About 45% of initial denials are reversed at the ALJ hearing stage. A South Dakota divorce attorney cannot represent you in SSA proceedings unless they're also admitted to practice before the SSA, but disability advocates and Social Security attorneys specialize in this.

Common Mistakes to Avoid

The most expensive mistake is remarrying before claiming divorced spouse benefits. Remarriage at any age (other than the age 60+ exception for survivor benefits) permanently terminates your right to collect on your ex's record. A 61-year-old who remarries loses access to a potential $1,500/month benefit — roughly $360,000 over a 20-year retirement. Wait until after claiming, or ensure the math of your new spouse's benefits exceeds what you'd lose.

Another frequent error is assuming the 10-year marriage rule can be extended by cohabitation, engagement, or common-law claims. South Dakota abolished common-law marriage for marriages entered after 1959 under SDCL § 25-1-29, so only a formal marriage license counts toward the 10-year threshold. Informal separations do not stop the marriage clock — only a filed, finalized divorce decree ends the marriage for SSA purposes.

Finally, many divorced spouses never apply because they incorrectly believe their ex must consent, that claiming will reduce their ex's benefit, or that the rules don't apply to them. None of these are true. The SSA estimates that hundreds of thousands of eligible divorced spouses leave billions of dollars in benefits unclaimed each year due to misinformation about the 10 year marriage rule and ex spouse social security divorce eligibility.
