Spouse's SS Disability

I recommend contacting Social Security directly as you may be eligible for a higher benefit as an ex-spouse.

If you are divorced, but your marriage lasted 10 years or longer, you can receive benefits on your ex-spouse's record (even if he or she has remarried) if:

• You are unmarried;
• You are age 62 or older;
• Your ex-spouse is entitled to Social Security retirement or disability benefits and
• The benefit you are entitled to receive based on your own work is less than the benefit you would receive based on your ex-spouse's work.

If you are eligible for retirement benefits on your own record we will pay that amount first. But if:

• the benefit on his or her record is a higher amount, you will get a combination of benefits that equals that higher amount (reduced for age).
• you have reached full retirement age and you are eligible for a spouse's benefit and your own retirement benefit, you have a choice.

  You can choose to receive only the divorced spouse's benefits now and delay receiving retirement benefits until a later date. If retirement benefits are delayed, a higher benefit may be received at a later date based on the effect of Delayed Retirement Credits.
