A courtroom-ready handbook with the Wisconsin Rules of Evidence, now includes free, 24/7, access to BarkaiBots - AI courtroom simulations for practicing advocacy skills that provide individualized, personal feedback and coaching based on the user’s questioning and advocacy performance. Updated May 2026.

The Wisconsin Rules of Evidence Handbook with Common Trial Objections & Evidentiary Foundations (6" x 9") was designed to be used in court and kept at your side in the office. Designed for quick courtroom reference when objections are made and evidence must be admitted. this practical guide includes:
1. A 16-page section on making and responding to common objections, including a list of over 60 trial objections.
2. More than 60 pages devoted to evidentiary foundations and impeachment, including 26 practical examples of foundations for introducing physical evidence, electronic evidence, hearsay, social media, emails, text messages, internet sites, authentication of digital evidence, and sample impeachment foundations.
New for 2026, this book also includes free access to BarkaiBots, interactive AI courtroom simulations that function as responsive practice partners and built-in coaches. Using a free ChatGPT account, lawyers and law students can rehearse courtroom advocacy 24/7 through realistic simulations with witnesses, judges, and opposing counsel, followed by coaching feedback after practice.

This guide was written for working lawyers and law students who must apply evidence rules in real time. When a witness answers unexpectedly or opposing counsel objects, there is no time to search through lengthy treatises. The handbook provides quick reminders of the most common objections and the foundations needed to introduce evidence at trial. The examples are designed to be read aloud and practiced so that phrasing becomes natural and the sequencing of questions becomes second nature.

The included BarkaiBots extend that practice beyond the printed page. Instead of simply reading examples, users can rehearse courtroom questioning in interactive simulations that respond in real time and then provide coaching feedback to help refine their advocacy.
