If the judge keeps interrupting and throws you off balance, politely ask for a moment to review your notes to be sure you've covered all key points. At the end of the case, it's appropriate to point out inconsistencies or fallacies in your opponent's testimony. But stick to the facts and never put your argument on a personal basis. As you conclude your presentation, ask the judge to award you the amount you're suing for plus court costs. If you win, you're normally entitled to have the other side pay your filing fee, any fees for service of papers and any fees that you paid to witnesses you had to subpoena.
Judges sometimes give their decisions at the end of the hearing.
It's also common for the judge to mail out a written decision a few days after the case has been heard. If the case goes against you, check out your appeal rights. All rights reserved.
