These forms are not intended to take the place of legal counsel. It is recommended that you obtain competent advice from a lawyer in your region before proceeding with a court action.
It is not uncommon for parties in a small claims action to represent themselves, and self representation is becoming more common in smaller civil suits as well (claims of up to $100,000). But you should not represent yourself in a criminal trial. If you can't afford a lawyer, one will be appointed for you by the court.
