Dear Liz: My fiancé was married to a wealthy woman for over 10 years. Will he lose his opportunity to use her earnings record as the basis for his Social Security retirement benefits if we get married?

Answer: The short answer is yes. Spousal benefits for divorced people are available only to those who remain unmarried. Many people confuse spousal benefits with survivors benefits. Survivors benefits for widows, widowers and divorced spouses of the deceased can continue after the recipient remarries, but only if the remarriage occurs after age 60.
You shouldn’t assume that your fiancé’s spousal benefits necessarily will be larger than his own benefit. His ex could have been wealthy without being a high earner. Even if she did, 100% of his own benefit could be worth more than 50% of hers. To find out for sure, he needs to contact the Social Security Administration.
