Depending on what your charge is, your matter could go one of a few different ways.
If it’s a fairly minor offence that you want to plead guilty to, it can usually be dealt with at your first court appearance. If you want us to try and have the charge dropped, then it will usually take a few more court appearances.
If the charge is more serious, or you want to contest it at a trial, it could go on for many months, and up to years, depending on which path you choose to take.
Serious charges that must proceed in the District and Supreme Court typically take about 9-12 months to be finalised for a plea of guilty, and 12-18 months if you want a trial before a jury.
