# How to prepare an oral trial with AI: from facts to arguments in 4 steps

Trial preparation is for many lawyers the most time-consuming and stressful task. AI does not eliminate that work, but it can dramatically compress the time spent on mechanical parts: legal research, case law selection and identifying weaknesses in your argument.

Step 1: Structure the facts

Before looking for legal arguments, you need clarity on which facts are uncontested, which are disputed and what your theory of the case is. Use Lexiel to generate a structured fact summary from the case documents.

Step 2: Legal research: from fact to rule

Describe the factual situation to the assistant in natural language. Lexiel searches the corpus and returns the applicable procedure, relevant articles and key case law.

Step 3: Case law selection: quality over quantity

Use Lexiel's filters (court + date + semantic description) to find the 3-5 most relevant judgments. Prioritise: TS unifying doctrine, Provincial Court judgments from your jurisdiction, recent decisions.

Step 4: Adversarial analysis: find weaknesses before the judge does

Lexiel's Vista Contraria function analyses your argument from the opposing party's perspective, identifying counter-arguments they may use, weak points in your theory and questions the judge may ask.
