New Hampshire Criminal Defense Laws

New Hampshire classifies criminal offenses as felonies (Class A and B), misdemeanors (Class A and B), and violations. The state does not use sentencing guidelines — judges have discretion within statutory ranges. New Hampshire uses the term "annulment" rather than "expungement" for sealing criminal records, and has specific waiting periods based on offense severity. DWI offenses carry escalating penalties with a 10-year lookback period.
