Reprinted from the Social Security Administration website:

If you get Social Security disability or retirement benefits and you get married again, there are four ways in which remarriage may affect your benefits:

1. If you receive Supplemental Security Income (SSI) benefits - If you marry, your spouse's income and resources may change your SSI benefit. If you and your spouse both get SSI, your benefit amount will change from an individual rate to a couple's rate.
2. If you receive benefits as a widow, divorced widow, widower, or divorced widower - You cannot get benefits if you remarry before age 60 or if you are disabled and remarry before age 50. If you remarry before you turn 50, you will not be entitled to survivor's benefits, unless the marriage ends.  If you remarry before you turn 60 and that marriage ends, you may become entitled or re-entitled to benefits on your prior deceased spouse's earnings record. Your benefits begin the first month in which the subsequent marriage ended if all entitlement requirements are met.
3. If you receive divorced spouse's benefits - Generally, your benefits end if you remarry. Check out if you are divorced for more information.
4. Benefits for a child under age 18 or student ages 18 or 19 - Benefits end if you marry. You can find more information in our page Benefits for Children.

Also, your remarriage after age 60 does not prevent you from becoming entitled to benefits on your prior deceased spouse's Social Security earnings record. Visit our Benefit Planners for more information.

A divorced ex-spouse who is at least 60 (50 if disabled) can also collect survivor benefits if he or she was married to the deceased for at least 10 years. Remarrying after turning 60 (50 if disabled) has no effect on survivor benefits.
