Dear Liz: My son is 59, and his ex-wife died approximately 12 years ago. She was a nurse and paid more into Social Security than he has. Is he entitled to her Social Security benefits as indicated in your article? How does he file and get more information? Must he wait until he is 62?

Answer: If their marriage lasted at least 10 years, he could begin divorced survivor benefits as early as age 60, or age 50 if he is disabled. (He can remarry at age 60 or later and still receive survivor benefits.)

Benefits are reduced if he applies before his full retirement age, which will be 67. Also, starting before full retirement age means the benefits are subject to the earnings test that withholds $1 in benefits for every $2 earned over a certain amount, which in 2023 will be $21,240.

If he earns too much to make starting early worthwhile, he could apply for divorced survivor benefits at age 67, when the earnings test goes away. His own retirement benefit could continue to grow until age 70, and he could switch at that point if his own benefit is larger.

But he’d be smart to consult a financial planner or use a Social Security strategy site, such as Maximize My Social Security or Social Security Solutions, to craft the best approach.

He can call Social Security’s toll free number at (800) 772-1213 for more information.

Dear Liz: I was told by Social Security that because I remarried at 60, I could still collect half of my ex’s benefits once he died. He has just died, and half of his benefit is greater than my own retirement benefit. My current husband has not started benefits. If I collect half of my ex’s benefit but want to later switch to collecting benefits on my current husband’s record (once he starts to collect) or to survivor benefits should he die before I do, can I do that?

Answer: The short answer is yes, although you’ve confused divorced spousal benefits with divorced survivor benefits.

While your ex was alive, you might have been eligible for a divorced spousal benefit if you had remained unmarried. That benefit would have been up to 50% of your ex’s primary insurance amount (the amount he would receive at his full retirement age).

The rules changed once your ex died. As a divorced survivor who remarried after age 60, you are entitled to up to 100% of what your ex was receiving. The survivor benefit will be reduced if you haven’t yet reached your full retirement age (which is currently between age 66 and 67).

Survivor benefits also offer more flexibility to switch later than other types of benefits. If you choose to begin receiving a surviving divorced spouse’s benefit now, you can switch to your own benefit at any point through age 70, if your benefit is higher, says William Meyer, founder of the Social Security Solutions claiming strategies site. You also can switch to receiving spousal benefits from your current spouse’s record once he starts collecting, if that benefit is greater than what you’re receiving from your former spouse’s record.

Figuring out the right way to claim can be tricky, so consider consulting an advisor or using claiming strategy software to determine what’s best in your situation.
