ex spouse's benefits.

You should probably consult directly with the Social Security Administration to get the details for your case.

Note that if you are eligible for retirement benefits on your own record the SSA 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.
