The situation where the question of remarriage and Social Security benefits usually comes up is survivor’s benefits.
If you are the divorced spouse of a worker who dies, you could get benefits just the same as a widow or widower, provided that your marriage lasted 10 years or more.
Benefits paid to you as a surviving divorced spouse who meets the age or disability requirement as a widow or widower won’t affect the benefit rates for other survivors getting benefits on the worker’s record.
Note: If you remarry after you reach age 60 (age 50 if disabled), the remarriage will not affect your eligibility for survivors benefits.
