Frequently Asked Questions

If you’re arrested, try to remain calm and respectful. If you don’t understand why you’re being arrested, it’s okay to politely ask for clarification. You have the right to remain silent — and it’s often in your best interest to use it. Don’t answer questions or make statements until you’ve spoken with a criminal defence lawyer. This protects your rights and ensures nothing you say is used against you later.

A criminal defence lawyer is your advocate and guide through the legal system. They can:
  • Clearly explain your legal rights and options
  • Investigate the facts of your case and gather evidence
  • Identify weaknesses in the prosecution’s case
  • Negotiate for reduced charges or penalties
  • Represent you in court and fight for the best possible outcome

Having experienced legal support can make a significant difference in how your case is resolved.

You have important legal protections if you’re being investigated by police. These include:

  • The right to remain silent — You are not required to answer questions.
  • The right to know why you’re being stopped or arrested — Police must tell you immediately.
  • The right to legal counsel — You can speak privately with a lawyer before answering any questions.
  • Freedom from unreasonable searches — Police must have a valid reason or warrant to search you or your property.
  • Protection from unlawful detention — Police cannot hold you without proper legal justification.
A criminal conviction can have serious and lasting consequences, including:
  • Legal penalties such as fines, probation, or jail time
  • A permanent criminal record that can affect your future
  • Employment barriers, especially in professions requiring background checks
  • Loss of privileges, such as a suspended driver’s license or travel restrictions
  • Social and personal impact, including stigma and strained relationships

If you’re facing charges, speaking with a qualified criminal defence lawyer can help you protect your future.
