I'm not sure why your lawyer told you that as I am not aware of any automatic early termination process. Probation is for a fixed term. The Department of Probation can elect to discharge you early or you can go into court and make a motion to be discharged early.
I am a former federal and State prosecutor and now handle criminal defense and personal injury/civil rights cases. Feel free to check out my web site and contact me at (212) 385-8015 or via email at Eric@RothsteinLawNY.com. The above answer is for informational purposes only and not meant as legal advice.
Most of my clients have been released from misdemeanor probation after 18 months to 2 years if they obeyed all the conditions and reported regularly.
It depends a lot on who your probation officer is. There is no automatic early termination. Just be on top of things and make sure you follow all conditions to the T and your chances of early termination are good.
Most clients get released early because Probation already has too many people to monitor as it is. However, as my collegue said, it will depend upon which Probation Officer you get and, in my experience, Nassau County POs are not the nicest and if you have any infraction of their rules, they will refuse your early release.
Good luck nonetheless.
