Judges hear many cases every day and don't have time to carefully read and memorize all the forms and documents they get. The judge will have a copy of any completed forms or trial books (if you're in Provincial Court) that you filed in the court registry but probably won't know exactly where to find specific information about your case.
This means you need to present your case to the judge in an organized, easy-to-follow way.
For example, it'll be much easier for the judge and the other person in your case (the law calls them the other party) to follow what you're saying if you make a list of your points or use the index of your trial book as your list when you're speaking. When you do this, say where the supporting information for each point is in your documents as you come to them so the other person and the judge can follow along.
If you're going to court for a first appearance in Provincial Court, the judge probably won’t know anything about your case. Ask family duty counsel for help if you're not sure what to do.
