Social Security on an Ex-Spouse's Record
A marriage that lasted at least ten years can produce a Social Security benefit long after the divorce, and the two beliefs that stop people claiming it are both wrong. It does not require the ex-spouse's cooperation, and it does not take a cent away from them. The Social Security Administration does not tell them the claim was made.
- Ten years:: The marriage must have lasted at least ten years to the date the divorce became final.
- Unmarried now:: You must be currently unmarried. Remarriage generally ends eligibility on the former spouse's record.
- Two years divorced:: If the ex-spouse has not yet claimed, you can still claim once the divorce is at least two years old, provided they are eligible.
- No effect on them:: Their benefit is unchanged, their current spouse's benefit is unchanged, and they are not notified.
Where the AI summary above gets this wrong
"You need your ex-spouse's cooperation to claim Social Security on their record."
That's surface-true. Here's what it misses:
- The claim is independent of them — Once the divorce is two years old and the ex-spouse is old enough to qualify, the claim can proceed whether or not they have filed. They are not asked, they are not told, and they cannot object. This is the single most common reason a valid claim goes unmade — people assume a conversation is required and would rather go without.
- It costs them nothing — The divorced-spouse benefit does not come out of the ex-spouse's payment, and it does not count against the family maximum that limits benefits paid on a current family's record. Several ex-spouses of the same worker can each claim without affecting one another.
- It is not additive to your own — You do not receive your benefit plus half of theirs. You receive the higher of the two figures. Where your own record is strong, the divorced-spouse benefit is worth nothing at all, and the arithmetic is worth doing before making decisions on the strength of it.
01 The four conditions
Four things have to be true. The marriage lasted at least ten years, ending in a final divorce. You are currently unmarried. You are at least 62. And your ex-spouse is entitled to Social Security retirement or disability benefits — entitled, not necessarily claiming.
That last distinction is where the two-year rule lives. If your ex-spouse has not filed, you can still claim on their record once the divorce has been final for at least two years, provided they are old enough to be eligible. A divorce finalised long ago clears this test automatically.
Remarriage generally ends the claim. If a later marriage itself ends, eligibility on the earlier record can be restored, which is worth checking rather than assuming — the wider financial picture in divorce and finances rarely includes it.

02 What it pays, and what it does not
The benefit is up to one-half of the ex-spouse's primary insurance amount — the figure they would receive at their own full retirement age, not the amount they actually receive if they claimed early or late. Delayed retirement credits they earned do not increase the divorced-spouse benefit.
It is not paid on top of your own. Social Security compares the two and pays the higher, so where your own record is the stronger one, the claim adds nothing. This is the same arithmetic as the spousal benefit within a current marriage.
Nothing is taken from your ex-spouse. Their payment is unaffected, their current spouse's is unaffected, and the family maximum does not apply to a divorced-spouse claim. More than one former spouse can claim on the same record.
Shows: the difference between your own benefit and half of your ex-spouse's, taken over the years you expect to collect, both measured at full retirement age. Ignores: the reduction for claiming early, cost-of-living increases, tax on the benefit, and whether the ten-year marriage test is met at all.

03 When to start it
Claiming before your own full retirement age reduces the divorced-spouse benefit permanently, on the same schedule as any other spousal claim. There are no delayed retirement credits on a spousal benefit, so waiting past full retirement age increases nothing.
That produces a clear shape: the divorced-spouse benefit reaches its maximum at your full retirement age and stays flat afterwards. If your own retirement benefit will eventually exceed it, the usual pattern is to take the smaller one first and switch, which the general timing question treats in more detail.
The claim is made at the Social Security Administration with the marriage certificate and the divorce decree. Those documents are the practical obstacle for most people, not the rules, and they are easier to obtain years before they are needed than in the month they are.

I have had this conversation with people who were divorced in the 1990s and had never once been told the benefit existed. The blocker is almost never the rules — it is the assumption that claiming means contacting someone they have spent thirty years not contacting. It does not. Take the marriage certificate and the divorce decree to Social Security and the rest is administrative. If the marriage reached ten years, find out what the number is before you decide it does not matter.
FAQ
Does my ex-spouse find out if I claim on their record?
No. The Social Security Administration does not notify them, their benefit does not change, and their current spouse's benefit does not change. Their permission is not required.
What if my ex-spouse has not claimed yet?
You can still claim, provided the divorce has been final for at least two years and your ex-spouse is old enough to be eligible. Their own filing decision does not gate yours.
Can I get my benefit plus half of my ex-spouse's?
No. Social Security pays the higher of the two, not the sum. If your own benefit already exceeds half of theirs, the divorced-spouse claim adds nothing.
