Criminal law paperwork covers every stage of a criminal case, from the first appearance and bail motion through pretrial motions, plea agreements, sentencing, and appeals. Deadlines in criminal cases are short and often unforgiving, and constitutional rights can be waived just by missing a filing. Using the right motion at the right time can mean the difference between evidence getting suppressed, charges getting reduced, or a case getting dismissed entirely.
