Most court systems have somewhat complicated rules of procedure that are strictly followed. Failure to follow the procedure can result in your case getting thrown out of court and a waste of your time and effort. To make matters worse, the evidence a court can consider in its decisions is limited. Most people who go to formal trials hire attorneys who are experts in procedure and evidence rules, but these attorneys typically charge by the hour. Trials (and the preparation before they start) can last weeks, months, or even years, which makes going to court an expensive endeavor.
