Witnesses and Evidence Rules in Hawaii Small Claims Court

Hawaii small claims court is designed to be informal, but "informal" doesn't mean anything goes. Evidence rules are relaxed under RSCD Rule 9 — the court isn't bound by the formal Hawaii Rules of Evidence — but the judge still expects organized, legible documentation. And if you need witnesses, there are specific ways to make sure they actually show up.

What Evidence to Bring

The judge decides based on what you put in front of them. For a defendant, that typically means:

Contracts and agreements. The original written contract, any change orders, email confirmations, or text messages that established the terms of the deal. If there was no written agreement, any communication showing what both parties understood is valuable.

Payment records. Canceled checks, bank statements showing transfers, Venmo or Zelle receipts, or signed cash receipts. These prove what you've already paid and undercut claims that you didn't.

Photos and videos. Damage to property, incomplete work, the condition of a rental unit at move-in versus move-out, a defective product. Date-stamped photos carry more weight.

Written communications. Text messages, emails, and letters between you and the other party. Print the full conversation thread, not just the messages that help your case — the judge will notice cherry-picking.

Invoices and estimates. If you paid someone else to fix work the plaintiff did poorly, bring that contractor's invoice and photos of the repairs.

Every piece of evidence must be on paper. Hawaii courts will not inspect evidence displayed on your phone screen. Print everything and bring two extra copies: one for the judge and one for the opposing party.

Organizing Your Evidence

Number each exhibit and create a one-page index listing what each item is and when it's from. This isn't required, but judges appreciate it — especially when the dispute involves a long timeline or multiple transactions. The easier you make it for the judge to follow your story, the better your chances.

Arrange the exhibits in chronological order. The dispute usually follows a natural timeline: agreement made, work started, problems arose, communication broke down, lawsuit filed. Walk the judge through that timeline using the documents.

Bringing Witnesses

A witness who was present during the events — watched the work being done, saw the condition of the property, was part of the conversation — can corroborate your version of what happened. Witnesses testify in their own words, briefly and to the point.

If your witness is willing to attend voluntarily, they simply show up at the hearing and the judge calls on them when appropriate. No paperwork needed for a voluntary witness.

If a witness won't attend voluntarily, you can request a Subpoena (Form 1DC49 in the First Circuit or 3DC49 in the Third Circuit) from the court clerk before the hearing. Confirm the correct form with the court in other circuits. The subpoena legally compels their attendance. A Subpoena Duces Tecum additionally requires them to bring specific documents — useful when a third party holds records relevant to your case (a bank, a property management company, a repair shop).

Apply for the subpoena well in advance of the hearing. The clerk issues it, but you're responsible for having it properly served on the witness.

What the Judge Can and Can't Consider

Because formal evidence rules don't strictly apply, hearsay is admissible — a witness can say "the contractor told me he wasn't coming back" without the technical objection you'd see in regular court. But the judge still weighs credibility. A printed text message from the contractor saying they're abandoning the job is stronger than someone's memory of a conversation.

Privileged communications (attorney-client, for example) are still protected even in small claims.
