Pretrial diversion typically lasts six months to two years. How long does pretrial diversion last in any given case comes down to three things: the seriousness of the charge, the defendant’s criminal history, and the policy of the prosecutor’s office handling the case. Federal diversion has a firm ceiling of 18 months.1U.S. Department of Justice. Archives – USAM 9-22.000 Pretrial Diversion Program State programs set their own terms, and there is no national standard.
What Drives the Length
Charge severity does most of the work. Misdemeanors generally fall on the shorter end, often six to twelve months. Felony-level charges push closer to eighteen months or two years because the prosecutor’s office wants more time to see whether the defendant has genuinely changed course. A shoplifting case and a fraud case will not carry the same supervision period, even in the same courthouse.
Criminal history is the next factor. First-time offenders are the primary audience for diversion and tend to receive the shorter terms. Someone with prior arrests who still qualifies will usually face a longer program with more supervision checkpoints along the way.
Local policy produces the widest swing. Each prosecutor’s office writes its own eligibility rules and program structure, so the same charge can mean six months in one county and a full year in the next.
The Federal Cap
Federal pretrial diversion is run by the U.S. Attorney’s Office in each district, with supervision handled by the U.S. Probation Service. The supervision period cannot exceed 18 months, and it can be shortened when a participant performs well.1U.S. Department of Justice. Archives – USAM 9-22.000 Pretrial Diversion Program In most federal cases, participants are diverted before formal charges are even filed; if they complete the program, no charges are brought, and if charges were already filed, they are dismissed.
Can You Finish Early
Whether you can wrap up ahead of schedule depends entirely on the jurisdiction. Some allow early termination; others require every participant to serve the full term regardless of compliance. The federal system explicitly permits reducing the supervision period below the 18-month maximum.1U.S. Department of Justice. Archives – USAM 9-22.000 Pretrial Diversion Program
Where early termination is available, expect a high bar. You generally need every active requirement finished (fees paid in full, community service hours completed, counseling done) and a substantial portion of the supervision term served with zero violations. Simply coasting without problems is not enough; the prosecutor’s office wants every box checked before it agrees to cut the timeline short.
What Happens When the Term Ends
Once you fulfill every condition and the supervision period runs out, the prosecutor’s office dismisses the original charges. Because no guilty plea was ever entered, you avoid a criminal conviction entirely.
The dismissal does not automatically erase the arrest. In most jurisdictions, the arrest itself remains visible on background checks unless you take the separate step of petitioning for expungement or record sealing. People often get tripped up here, assuming a dismissed case is invisible and then finding it on an employment or housing screening months later. After completing diversion, check your jurisdiction’s expungement rules and file the petition as soon as you are eligible. Completing diversion and having charges dismissed generally puts you in a strong position to qualify.
What Happens If You Don’t Finish
Failing to comply ends the arrangement and sends the case back to the regular prosecution track. Common violations include a new arrest, a failed drug test, missed check-ins, or incomplete community service. Any one of these can pull you out of the program before the term is up.
When diversion is revoked, the original charges are reinstated as if the program never existed. Prosecution picks up where it paused, and any statements or admissions you made during intake can potentially be used against you, depending on the jurisdiction and the terms of your original agreement. One consequence people overlook: because you likely waived your right to a speedy trial when you entered diversion, the prosecution can proceed even though months or years have passed since the original arrest. You do not get to argue the case took too long.
That is why the length matters in practice. A six-month program and a two-year program are very different commitments, and the longer the term, the more chances there are for something to go wrong before you reach the dismissal at the end.
