I will turn 62 on 5/ 2018. I was married for 25 years and have been divorced for 4. Is it possible to collect on my benefits at 62 and then on my ex's at full retirement age?

Hi,

No, whenever you apply for benefits, you will be deemed to be filing for both retirement benefits on your own record and for divorced spousal benefits (https://www.ssa.gov/planners/retire/deemedfaq.html).
