Good afternoon Judy,
I'm Doug, and I'm very sorry to hear of your situation. My goal is to provide you with excellent service today.
Yes, it is possible for you to make an ex-spouse survivor claim. Now, keep in mind that you cannot collect a survivor benefit and your own retirement benefit at the same time. However, if your ex's benefit was higher than yours was at the time he passed, then you will be able to increase your social security benefit by filing for a survivor benefit now. This cannot be done online though and so you must either call social security to make the claim---or better yet, go to your local social security office to put in the claim for the survivor benefit.
You will need the following information to make the claim.
1. Both your social security number and that of your ex.
2. A copy of your marriage license.
3. A copy of the divorce decree.
4. A copy of his death certificate.

I hope that I have been able to fully answer your question. As I am not an employee of JustAnswer, please be so kind as to rate my service to you. That is the only way I am compensated for assisting you. Thank you in advance.
I wish you and yours the best in 2016,
