Ex-Spouse Social Security Benefits: Divorced Spouse Guide

If you were married at least 10 years and remain unmarried, you can claim up to 50% of your ex-spouse's Social Security benefit at your Full Retirement Age — without affecting their benefit or notifying them. Your ex's current marital status and whether they have already filed do not affect your eligibility.

The Basics: Who Can Claim Divorced Spouse Benefits

Before diving into calculations, confirm that you meet all the eligibility requirements.

You qualify if:

Your marriage lasted at least 10 years You are currently unmarried (or remarried at or after age 60) You are at least 62 years old Your ex-spouse is entitled to Social Security retirement or disability benefits If your ex has NOT yet filed, you must have been divorced for at least 2 years — meaning you do not need to wait for your ex to file first

What does NOT affect your eligibility:

Your ex-spouse's current marital status — if they remarried, you can still claim on their record Whether your ex-spouse knows you're claiming — they are not notified How many years ago you divorced — as long as the marriage itself lasted 10 years Whether your ex has filed for their own benefits — if you've been divorced 2 or more years, their filing status is irrelevant

How to Calculate Your Divorced Spousal Benefit

The formula for divorced spousal benefits is identical to that for current spousal benefits.

The core formula:

• Your divorced spousal benefit maximum = 50% of your ex-spouse's PIA (Primary Insurance Amount — their benefit at Full Retirement Age)
• Social Security pays you the higher of your own benefit or the divorced spousal benefit
• The comparison and calculation happen automatically — you do not have to choose one or the other

Step-by-step calculation:

1. Find your ex-spouse's PIA. You can estimate this from their Social Security statement if you have access, or you can contact the SSA and request it. You may need to provide proof of marriage and divorce dates.
2. Multiply their PIA by 50%. This is your divorced spousal benefit maximum at your Full Retirement Age.
3. Compare to your own PIA. Calculate what your own benefit would be at Full Retirement Age.
4. If divorced spousal is greater: You'll receive your own benefit plus a supplement bringing you up to the divorced spousal amount.
5. If your own PIA equals or exceeds the divorced spousal: No divorced spousal supplement — you simply receive your own benefit.

Worked examples:

Example A: Ex-spouse PIA = ,400. Divorced spousal maximum = ,200. Your PIA = . At FRA you receive ,200 (the divorced spousal amount). The supplement on top of your own benefit is .

Example B: Ex-spouse PIA = ,600. Divorced spousal maximum = ,800. Your PIA = ,000. No divorced spousal supplement — you receive your own ,000 because it exceeds the divorced spousal maximum.

Example C: Ex-spouse PIA = ,000. Divorced spousal maximum = ,500. Your PIA = ,300. You receive ,500. The supplement is . In this case, ask yourself: is the supplement worth the constraints of claiming divorced spousal benefits versus optimizing your own benefit trajectory?

Early Claiming Reductions for Divorced Spousal Benefits

Divorced spousal benefits follow the same early claiming reduction schedule as regular spousal benefits. Claiming before your Full Retirement Age permanently reduces the amount.

• Claim at 62: approximately 30% reduction — you receive about 70% of the divorced spousal maximum
• Claim at 65: approximately 13% reduction
• Claim at FRA (67): full divorced spousal amount — no reduction
• Wait past FRA: No additional increase — divorced spousal benefits do not earn delayed retirement credits

Example: Ex-spouse PIA = ,000. Divorced spousal maximum = ,500. Your PIA = .

• Claim at 62: ,500 x 0.70 = ,050 (versus your own reduced to at 62)
• Claim at FRA: ,500 (versus your own full at FRA)
• Own benefit at 70: — still less than ,500 divorced spousal

In this scenario, there is no incentive to delay past FRA since the divorced spousal benefit will not grow — and your own benefit at 70 is still well below the divorced spousal amount.

Comparing Own Benefit vs. Divorced Spousal Benefit: Decision Framework

The central strategic question: Is it better to claim divorced spousal benefits, or should you let your own benefit grow to 70 with delayed retirement credits?

When divorced spousal benefits win:

Your own benefit, even maximized at 70, is well below 50% of your ex-spouse's PIA. In this case, waiting past FRA to grow your own benefit with delayed credits adds very little compared to the divorced spousal amount you could be receiving. Claiming divorced spousal at FRA — or even slightly earlier — is often the right move.

When your own benefit wins:

Your own benefit at 70 equals or exceeds 50% of your ex-spouse's PIA. In this situation, the divorced spousal supplement is small or nonexistent, and you are better off delaying your own benefit to maximize it for life. This also matters if you want to maximize the survivor benefit for a current spouse, since your own delayed benefit — not a divorced spousal benefit — is what they would inherit as a survivor. For the complete divorced spouse strategy, see the divorced spouse Social Security strategy guide. For coordinating your full household claiming plan, see the married couples Social Security strategy guide.

The practical calculation:

Multiply your own PIA by 1.24 (your benefit at 70). Compare that to 50% of your ex-spouse's PIA. If your-own-at-70 exceeds 50% of their PIA, delaying your own makes financial sense. If your-own-at-70 is still below 50% of their PIA, there is little reason to delay past FRA since you will receive the divorced spousal amount regardless.

Divorced Survivor Benefits: The Often-Overlooked Extension

There is an important but frequently missed benefit connected to divorced spousal benefits: if your ex-spouse passes away, you may be eligible for divorced survivor benefits — and these are substantially larger.

Divorced survivor benefits at a glance:

• Pays up to 100% of what your ex-spouse was receiving at death — compared to the 50% cap of divorced spousal benefits
• Available as early as age 60 (or 50 if you have a qualifying disability)
• Marriage must have lasted at least 10 years
• You must not have remarried before age 60
• Does NOT require you to have been collecting divorced spousal benefits while your ex was alive
• Does NOT affect the current spouse's survivor benefit — both can collect simultaneously

How to Apply for Divorced Spousal Benefits

Applying is straightforward, and you do not need your ex-spouse's cooperation or even their full Social Security number.

How to apply:

• Online at SSA.gov

Documents typically needed:

• Your Social Security card or number
