Dear Liz: I am 68 and plan to delay starting Social Security until I’m 70. I was married for 15 years prior to an amicable divorce 15 years ago. My ex just turned 60 and remains unmarried but may possibly marry at some future time. Does she qualify for survivor benefits? If so, what can I do to help ensure that she can efficiently apply for that benefit? We have already reviewed her option to assume my benefit upon my demise, but our benefits are virtually at identical levels and so that option does not seem applicable.

Answer: You seem to have confused divorced survivor benefits with divorced spousal benefits. She may well be eligible for both, but the only way you can help her get survivor benefits is to die. It’s great that you two are still friends, but that may be taking friendship a little too far.

Your ex is too young to claim a divorced spousal benefit, which isn’t available until she turns 62. She wouldn’t be able to get the full amount, which is 50% of your benefit at your full retirement age, until she reaches her own full retirement age. If she was born in 1959, then her full retirement age is 66 years and 10 months.

Furthermore, she would get a divorced spousal benefit only if that’s larger than her own benefit. If your benefits are “virtually identical,” that’s not likely to be the case.

If you should keel over tomorrow, though, she would be eligible to receive a divorced survivor benefit and put off receiving her own. Survivor benefits are available starting at age 60, or age 50 if the survivor is disabled, or at any age if the survivor cares for the dead person’s child who is under 16. Your ex also could marry at 60 or older without losing her survivor benefit. People who receive divorced spousal benefits, on the other hand, lose that benefit if they remarry.
