1. Evidence
Before trial, you should gather all the evidence necessary to prove your claim or your defense. Anything that will help prove the facts in dispute should be brought to court. This includes photographs, written agreements, an itemized bill or invoice that is receipted or marked "paid," written estimates of the cost of the service or repairs, a receipt for the purchase of an item or the payment of a debt, canceled checks, and correspondence. If you rely on estimates, two different written itemized estimates of the cost of the service or repairs are required. If possible, merchandise that is in dispute should be brought to court.
Testimony, including your own, is evidence. Any witness whose testimony is important to your case may testify. This can be a person who witnessed your transaction or someone whose special knowledge and experience makes him or her an expert on the cost of the service or repairs that were provided or may be required.You may have to pay an expert witness for his or her time.
2. Subpoenas
If you are unable to get a witness to appear voluntarily, you may apply for issuance of a subpoena to the clerk of the Small Claims Court, who will give you the necessary information. A subpoena is a legal document that commands the person named in the subpoena to appear in court. An expert witness may not be compelled to testify by subpoena, but you may pay the expert witness for coming to court to testify.
You also may apply to the clerk of the Small Claims Court for a "subpoena duces tecum," which is a legal document that directs someone to produce a bill, receipt, or other written document or record you need.
Either party may apply for a subpoena up to 48 hours before a trial date.
You must arrange for service of the subpoena and the payment of a $15.00 witness fee and, where appropriate, travel expenses for the person subpoenaed. Except where the travel is entirely with a city, a subpoenaed witness is entitled to 23 cents a mile as travel expense to and from the court from the place he or she was served with the subpoena. Service of the subpoena may be done by any person (including a friend or relative) who is 18 years of age or older, except that you or any other party to the action may not serve the subpoena.
