It is very common to forget about criminal cases. Haze of time, haze of drugs, precatory memory interference, inter alia.
I applaud the OP for wanting to be accurate. Smart move.
Call the Office of the Clerk of the counties where you were arrested. They should be able to help you out (8AM-5PM).
You want the "CCS" (Chronological Case Summary) for each case (if the case was filed). They may refer to the CCS as the "docket" too. It need not be certified for right now.
You may have to pay to have them e-mail or mail to you. Worth it if you do not know.
The CCS will have the cause number, the initial charges, what you pled or were convicted of, and the sentencing order, or the withhold prosecution or the dismissal order.
Yea, but to not know you are a convicted felon or not? That's a pretty big detail to forget or not be sure of.
