You will need to be age 62 to file for his benefits and not remarried (unless it happened after age 60). From the SS website:
"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:
(1) You are unmarried;
(2) You are age 62 or older;
(3) Your ex-spouse is entitled to Social Security retirement or disability benefits and
(4) 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 your ex-spouse has not applied for retirement benefits, but can qualify for them, you can receive benefits on his or her record if you have been divorced for at least two years.
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."
Remember if you file before full retirement age (age 66 this year) your benefit will be reduced per Social Security rules for the early retirement reduction. So it will be up to you when you want to start collecting. A Social Security agent ccan explain to you what benefits you will receive and when and compare this spousal benefit to your normal retirement benefit. Also remember, you will not receive both benefits (the spousal and your normal SS benefits), just the higher of the two.
