Start with the court file, not with speeches
Before you practice what to say, collect what the court already has, what you filed, what the other side filed, and what still needs to be attached or corrected. A clean file prevents half the confusion people blame on nerves.
Write a one-page case map
List the issue, the outcome you want, the three to five facts that support it, and the documents that prove those facts. If you cannot explain the case on one page, your hearing notes will likely be too scattered too.
Prepare hearing notes that are short enough to use
Your notes should tell you what to say first, what document to mention next, and what question you need answered before you leave the courtroom. Long scripts often collapse under stress; short checkpoints hold up better.
