Dear Liz: I’m remarried and don’t plan to claim a spousal benefit on my husband’s Social Security, as my benefit will be four times what his will be. My previous marriage ended in divorce at 10 years, and my ex died two years ago. How do I find out if I’m eligible to collect on my ex’s Social Security record? I am 63 and want to wait until 70 to apply for my own benefit, but I would like to retire at the end of this year.

Answer: You’ve already cleared one hurdle, which is that your previous marriage lasted 10 years. So whether you qualify for divorced survivor benefits depends on how old you were when you remarried.

Divorced people who remarry after they reach age 60, or age 50 if they’re disabled, can qualify for divorced survivor benefits. Those who remarry before that point are out of luck.

Note, please, that the remarriage rule applies only to survivor benefits. Spousal benefits are a different story. While divorced people can qualify for spousal benefits if their marriages lasted at least 10 years, the ability to get a spousal benefit ends when they remarry.

Survivor benefits are also different from spousal benefits in that you will be free to switch from a survivor benefit to your own benefit at 70. When you apply for spousal benefits, you typically have to apply for your own benefit at the same time and will get the larger of the two. You can’t switch to your own benefit later.

Dear Liz: Will my wife, after I’m gone, be able to claim one half of my Social Security benefits because she is the surviving spouse? I am concerned and confused, because her monthly Social Security benefit is much larger than mine. Does that affect this aspect of the available benefit?

Answer: If by “gone” you mean “dead,” then no, that’s not how survivor benefits work.

When one member of a married couple dies, the surviving spouse does not continue to get two benefit checks. The survivor is given the larger of the couple’s two benefits. If she’s already receiving much more than you, then she will continue taking her own benefit and your checks will end.

The “one half” benefit is the spousal benefit, which is paid out while the primary earner is still alive. Typically when married people apply for Social Security, the retirement benefit they earned is compared with their spousal benefit, which is up to one half of what the other spouse has earned. (The amounts are reduced if the person applies for benefits before his or her own full retirement age.) The applicants get the larger of the two checks.

Spousal benefits also are available to divorced spouses, if the marriage lasted at least 10 years.
