“I Want to Tell the Jury My Side”

The night before the defense case

The associate is second chair on a criminal trial. The prosecution rested this afternoon. Tomorrow the defense decides whether the client testifies.

The team's advice is clear: don't. The prosecution's case has gaps, the client is quick-tempered, and his account has shifted in small ways that a skilled cross-examiner will find.

The client disagrees.

"I didn't do this. If I don't get up there, the jury will think I'm hiding something. I want to tell them my side."

The lead attorney has been called to another matter and asked the associate to have this conversation. The decision will be made tonight.

The decision belongs to the client

Under the ABA Model Rules — as adopted in each jurisdiction — certain decisions in a criminal case are reserved to the client after consultation with the lawyer, and whether to testify is among them. Courts in many jurisdictions also recognize the defendant's right to decide, and some confirm the decision with the defendant on the record.

That allocation makes advising a client whether to testify a particular kind of counseling conversation.

The lawyer's advice matters enormously, and it doesn't control. The client is entitled to the lawyer's full, candid view. He is also entitled to reject it.

The risks are concrete but hard to imagine. Cross-examination is abstract until you're in it. Clients who have never been cross-examined consistently underestimate what it involves.

And the client's reason is often emotional and legitimate. Wanting to tell your own story when accused is a deeply human impulse. Dismissing it doesn't help the client decide.

Advise fully and specifically

Start with his reasons. "Tell me why it matters to you to testify." Understanding what he hopes to achieve lets the advice address it directly.

Explain the risks concretely, not generally. Not "cross-examination can be difficult" but "The prosecutor will ask about the two different times you gave for when you left. She'll ask about your temper. She'll ask about [specific issue]. Here's how that could land." The more specific the risk, the more real the decision.

Explain what not testifying means. Including what the jury will typically be told and what the defense will argue without his testimony. Clients often assume silence is fatal.

Give your recommendation clearly. "My advice, and the lead attorney's, is that you don't testify. Here's why." Then stop, and let him respond.

Where the court and practice allow, let him experience it. A realistic practice cross-examination — within the ethical limits of witness preparation — is often the single most informative thing a client can have before deciding. Many clients change their minds after one; some become more determined. Either way, the decision becomes an informed one.

Then respect the decision

Return the decision explicitly. "This is your decision. Whatever you decide, we'll do everything we can for you."

If he decides to testify, prepare him properly. Not grudgingly. A client who testifies against advice needs better preparation, not less.

Document the advice and the decision. The firm's practice — and sometimes the court's — will call for a clear record that the client was advised and chose.

And know the boundary. If a lawyer knows a client intends to testify falsely, the professional conduct rules impose specific obligations that vary by jurisdiction and are complex in criminal cases. That situation calls for immediate consultation with supervising counsel and, where appropriate, ethics counsel — not a decision made alone the night before.

Four ways it goes wrong

The overrider, who treats the decision as the lawyer's and pressures the client into silence.

The abstract advisor, who warns about cross-examination in general terms the client can't evaluate.

The dismisser, who treats the client's desire to be heard as irrational rather than addressing it.

The grudging preparer, who, having lost the argument, prepares the client half-heartedly.

Why this isn't trained

The allocation is taught as doctrine. Every law student learns who decides whether to testify. Few practice the conversation when the client and lawyer disagree.

Advice is given in general terms. Lawyers know cross-examination is dangerous; they often describe it in ways clients can't picture.

Time pressure is severe. The decision frequently comes at the end of the prosecution's case, overnight, with the lawyer exhausted and the client anxious.

And practice clients agree too easily. Colleagues playing a defendant accept the advice. The real one — innocent in his own mind and desperate to be heard — doesn't.

What client decision simulation can rehearse

A ten-minute simulation can hold a defendant who wants to testify, with a clear emotional reason and a specific vulnerability on cross — so the lawyer practices advising concretely, respecting the decision and documenting it. A second simulation can run the prosecution's likely cross, for the client to experience. The AI agents in Foretell AI play both roles; the case, advice, court practice and ethical obligations stay with the defense team.

Four versions to build:

Design caution. The allocation of decisions in criminal cases, on-record colloquies, impeachment rules and obligations regarding client testimony vary by jurisdiction and are governed by professional conduct rules and constitutional law. Modules must not rehearse any approach to client perjury issues, which require supervising and ethics counsel. Practice cross-examination of clients must stay within the ethical limits of witness preparation. Nothing here is legal advice.

Designing the module

Ten minutes, scored against a client counseling rubric for reserved decisions.

Pass one — understanding. Did the lawyer ask why the client wants to testify, and address that reason?

Pass two — advice. Were risks described concretely? Was a clear recommendation given?

Pass three — respect. Was the decision explicitly returned to the client, and was it documented?

Rubric on observable behavior: Were the client's reasons explored? Were specific cross-examination risks described? Was the alternative explained? Was a recommendation given clearly? Was the decision returned explicitly? Was any pressure applied after the client decided? Was the advice documented?

Concreteness of risk is the measure. Clients decide on what they can picture, and the difference between "cross can be tough" and a specific list of questions is the difference between an informed choice and an uninformed one.

For defense firms, public defenders and trial teams

It's one of the most consequential decisions in a trial. Getting the conversation right protects the client and the integrity of the defense.

It's high-pressure and often overnight. Rehearsal means the lawyer has the structure ready when the moment arrives.

It connects preparation to advice. Practice cross, run ethically, gives clients the most useful information they can have.

And for law schools, it's the criminal-practice counterpart to general client counseling — where the client's authority is at its clearest and the stakes are highest.

Frequently asked questions

Who decides whether a criminal defendant testifies? Under the professional conduct rules in most jurisdictions, and as recognized by courts, the defendant decides after consulting with counsel.

How should a lawyer advise a client about testifying? Understand the client's reasons, describe the specific risks of cross-examination and the implications of not testifying, give a clear recommendation, and then return the decision to the client.

What if the client wants to testify against the lawyer's advice? Respect the decision, document the advice and choice, and prepare the client thoroughly. A client testifying against advice needs better preparation, not less.

What should a lawyer do if they believe the client will lie on the stand? Consult supervising and ethics counsel immediately. The obligations are specific, vary by jurisdiction and are complex in criminal cases.

The short version

He wants to tell the jury his side, and it's his decision.

Ask him why. Tell him specifically what the prosecutor will ask. Explain what staying silent really means. Give your advice plainly. If you can, let him feel a real cross before he decides. Then hand the decision back — and if he chooses to testify, prepare him as well as you've ever prepared anyone.

The lawyer's job is to make the choice informed. It was never to make the choice.

Foretell AI lets defense teams and law schools build client decision simulations — including testify-or-not counseling, practice cross-examination and reserved-decision conversations like the one above — with configurable AI clients and prosecutors, recordings and rubric-based evaluation. If your lawyers first have this conversation the night before the defense case, we're happy to walk through how other teams have structured it.
