A pre-trial diversion is a special program that allows someone to get a reset that is 1 year long. During that time the defendant completes a program that results in the charges being dismissed. The program typically entails random drug tests, classes, community service, reporting once a month, paying monthly fees and staying drug and alcohol free.
As an attorney who does a lot of work in this area, I have learned that many people are confused by the difference between Sealing a Record, a Petition for Non-Disclosure and Expunctions. People typically call and tell me they want to expunge their record. But there are different things that different people are eligible for.
If you read my older blog entry on Non-Disclosures, you know that a non-disclosure is a type of sealing of a record for an adult who successfully completed Deferred Adjudication. On a deferred adjudication the case is dismissed upon completion, there is never a conviction, and the arrest record can be partially non-disclosed to the general public (but not the government or law enforcement).
