Dear Liz: I have been with my significant other for over 30 years. We have an adult son. My significant other has a much larger Social Security benefit than I will have when it’s time for me to retire. I understand that if we were to marry and something happened to him, I would receive his benefit. But the law on Social Security is confusing. It says you have to be married several years to collect your spouse’s benefit unless you have a child. If we were married soon, would I be eligible for his benefits if something happened to him or would we have to be married for many years?

Answer: Social Security benefits can be confusing, but you don’t have to be married for many years to receive benefits.

To qualify for survivor benefits, you typically must have been married for at least nine months. To qualify for spousal benefits, you generally have to be married a year. If you have a natural child together and that child is a minor, the one-year requirement for spousal benefits is waived.

Survivor benefits are what you get when a higher-earning spouse dies. The benefit is 100% of what the deceased spouse received (or earned, if he hasn’t started benefits), but the amount is reduced if you as the surviving spouse begin benefits before your own full retirement age. The current full retirement age is 66 and will rise to 67 for people born in 1960 and later.

Spousal benefits are what you can receive while a spouse is still alive. This benefit is typically equal to half that spouse’s benefit and is reduced to reflect early starts.

You’ll need a longer marriage to get benefits should you divorce. The marriage must have lasted 10 years, and you must not be currently remarried to receive divorced spousal benefits based on your ex’s work record. For divorced survivor benefits, the marriage also must have lasted 10 years but you’re allowed to remarry at age 60 or later.
