Telling a story in court is not like telling it to a friend. When you talk to a friend, you often start at the beginning, build up some suspense and finish with a punchline. In court you do the opposite. You want the judge to know as soon as possible why you are there. Briefly give the facts, usually in chronological order.
Group facts together.
Decide what the main points and issues are and stick to those in telling your story, referring to evidence that supports your position. If you need documents which are not in your possession, you can request them through a Subpoena Duces Tecum. This is a form you get from the Clerk, which you serve on the party who has the documents. You don't want to overwhelm the judge with either the number or complexity of your materials. In some cases where there are not witnesses or documents, it becomes a matter of one person's word against another.
