Witness Evidence Guide

The Reality of Trial Time

A courtroom is not a television drama; it is a highly inefficient, severely time-constrained environment. In a standard five-day trial, the actual time available for witness testimony is drastically reduced by procedural necessities. Significant time is consumed by opening submissions, ongoing arguments regarding admissibility or evidentiary objections, closing submissions, and ultimately, costs submissions at the conclusion of the trial.

What little time remains is almost entirely consumed by the main parties. It is incredibly common for the Applicant and Respondent to spend a day and a half each in the witness box under cross-examination. Because judicial time is the most valuable commodity in the room, Judges have zero tolerance for litigants who waste it. Every witness you add to your list must justify the time it takes to swear them in.

The True Value of a Witness: Facts vs. Opinions

You do not call a witness to tell the Judge that you are a good person or that your ex-partner is a bad one.

The Tactical Value: A witness is a mechanism to introduce objective evidence into the trial. You call them for two specific reasons:

1. To anchor documents: To introduce and verify a specific email chain, SMS thread, or financial record that you cannot introduce yourself.
2. Direct Observation: To testify about specific, relevant events they saw with their own eyes or words they heard with their own ears (e.g., "I saw the Mother lock the child in the car," not "I think the Mother is reckless").

The Three Stages of Evidence

If a witness takes the stand, their evidence is tested in three distinct phases:

• 1. Examination-in-Chief: This is where the witness gives their primary evidence. To save highly valuable trial time, this is almost entirely done "on the papers." A witness will commonly file a sworn written affidavit prior to the trial, and that document legally constitutes their entire examination-in-chief. You generally do not get to ask them to tell their story verbally in the box; instead, you simply ask them to confirm their name, address, and that the contents of their affidavit are true and correct.
• 2. Cross-Examination: This is the main event. The opposing party (or their lawyer) gets to aggressively test the witness's memory, credibility, and motives. If your witness is fragile or prone to anger, the opposing side will exploit it here.
• 3. Re-Examination: This is your brief opportunity to clean up any specific damage done during cross-examination. It is highly restricted. You cannot introduce new topics or ask leading questions; you can only ask them to clarify an answer they gave to the opposing side.

The Golden Rules of Witness Management

1. Never Call a Witness If You Don't Know What They Will Say

Calling a "wildcard" witness in the hope they will support you is procedural suicide. If you do not know exactly how they will answer a question, do not ask it.

2. There is "No Property" in a Witness

Many litigants mistakenly believe that because a witness is on their list, the other side cannot speak to them. This is false. There is no property in a witness. Once their affidavit is filed, the opposing lawyer is completely legally entitled to contact them, interview them, and test what they are going to say before the trial even begins.

3. The Danger of the Subpoenaed Witness

Issuing a subpoena forces someone to attend court under threat of arrest. It is a powerful tool, but highly dangerous. A witness who has to take time off work and sit in a stressful court waiting room against their will is likely to be hostile. The opposing side knows this, and a skilled cross-examiner will easily exploit a hostile, annoyed witness to draw out testimony that damages your case just out of spite. Only subpoena a hostile witness if their written evidence is absolute, undeniable, and strictly necessary to prove a material fact.
