A trial consultant is a behavioral science professional who helps legal teams prepare for trial, working behind the scenes on jury selection, witness preparation, mock trials, courtroom visuals, and related tasks that shape how jurors perceive a case. Most come from psychology, sociology, or communication backgrounds, and they tend to show up in high-stakes civil and criminal matters where the outcome depends as much on presentation as on the underlying facts.
What a Trial Consultant Does
The scope is broad. The American Society of Trial Consultants lists services ranging from pretrial research and jury selection to witness preparation, trial graphics, venue surveys, and post-trial juror interviews.1American Society of Trial Consultants.

Jury Selection and Voir Dire
Jury selection is where many consultants earn their keep. During voir dire, the judge and attorneys question prospective jurors to assess their suitability for the case.2United States Courts. Juror Selection Process A consultant’s job is to go deeper than surface answers. They draft supplemental juror questionnaires designed to surface attitudes a standard round of questioning would miss, and they research public social media, property records, and political affiliations to build a fuller picture of each person in the jury box.
Before voir dire begins, many consultants build a juror risk profile from earlier mock trial results or community surveys. The profile identifies demographic, attitudinal, and experiential traits most correlated with verdicts for or against the client. During selection itself, the consultant sits with the trial team, tracks responses in real time, and recommends which jurors to challenge for cause and where to spend peremptory strikes. The point isn’t to seat jurors who will favor the client. It’s to screen out people whose existing biases make a fair hearing unlikely.
Mock Trials and Focus Groups
A mock trial is a rehearsal of the case presented to jury-eligible participants recruited to mirror the demographics of the actual venue. The consultant designs the exercise, screens participants, observes reactions to each side’s arguments, and debriefs the group after deliberation to learn which evidence persuaded them and where confusion set in.
Focus groups do similar work in a less formal setting, usually with a smaller group and a narrower set of issues. Both formats let attorneys stress-test a case theory before they commit to it in open court. Weaknesses found at this stage can be fixed; weaknesses found mid-trial generally cannot.
Witness Preparation
Witness preparation is one of the more hands-on services. The work focuses on helping witnesses communicate clearly, manage anxiety, and present testimony in a way that reads as credible. That might mean coaching a corporate executive to stop hedging every answer, or helping a nervous plaintiff get used to the pace of cross-examination.
Consultants typically run practice sessions that simulate courtroom conditions, including hostile questioning, and give feedback on body language, vocal tone, and the tendency some witnesses have to volunteer information nobody asked for. There is a legal line between preparation and coaching, covered further down.
Courtroom Visuals
Complex cases often turn on whether jurors can follow the facts. A patent dispute over semiconductor architecture or a medical malpractice case involving surgical anatomy can lose a jury quickly if the presentation stays purely verbal. Consultants design timelines, diagrams, animations, annotated photographs, and process charts to bridge that gap, drawing on research into how color, typography, and layout affect attention and retention.
A practical point from experienced practitioners: a static trial board that stays visible during testimony sometimes outperforms a slick electronic presentation, because jurors can glance back at a physical board during closing argument while a slide from ten minutes ago is gone.
Change of Venue Surveys and Post-Trial Interviews
When pretrial publicity threatens a fair trial, consultants support venue change motions by running community attitude surveys in the current venue and proposed alternatives, then applying statistical analysis to show whether the differences in awareness and bias are meaningful. Courts respond better when the methodology holds up.
After a verdict, some consultants interview jurors to learn what carried weight in deliberation and where the losing side went wrong. Judges generally control whether post-verdict contact is allowed, and many courts require counsel to request permission first, even where no statute prohibits the contact outright.
When It Makes Sense to Hire One
Trial consultants show up most often where the stakes justify the expense and the outcome depends heavily on how jurors, judges, and witnesses perceive the facts: large personal injury and wrongful death suits, complex corporate litigation, intellectual property disputes, product liability cases, and high-profile criminal prosecutions. In smaller cases with straightforward facts, experienced trial attorneys handle these functions themselves.
Timing matters. The most effective engagements start early, because findings from mock trials and community surveys can reshape the entire case strategy. A consultant brought in the week before trial can still help with voir dire and visuals, but the strategy is already locked in by then.
What Trial Consultants Cost
Pricing varies widely depending on the service, the consultant’s experience, and the complexity of the case. Individual services like jury selection assistance or witness preparation sessions might run a few thousand dollars. A full mock trial with recruited participants, a designed venue, and statistical analysis of results typically ranges from roughly $10,000 to $60,000 or more. A comprehensive engagement covering pretrial research, mock trials, community surveys, witness prep, courtroom graphics, and in-court support can reach six figures in major litigation.
Hourly rates depend on experience, geographic market, and specialization, with senior consultants at established firms charging considerably more than solo practitioners. Many consultants quote project-based fees rather than hourly rates for defined deliverables like a mock trial or a venue survey. The spending looks different when verdict exposure is $500,000 versus $50 million, which is the comparison legal teams actually make.
How to Evaluate a Consultant
No license or certification is required to practice. The ASTC states plainly that “no specific education or certification is required,” and that consultants come from “vastly different backgrounds.”1American Society of Trial Consultants. Join ASTC The field includes PhDs in psychology with decades of jury research alongside people who moved over from marketing or communications with no graduate training. That makes vetting the real work.
Most established consultants hold graduate degrees in psychology, sociology, communication, or a related social science. Some have law degrees or practiced law before switching. The strongest qualification is courtroom experience: a consultant who has worked hundreds of voir dires brings pattern recognition no degree program teaches. Ask for case histories, references from attorneys who have retained them, and specifics about methodology rather than relying on credentials alone.
The ASTC maintains a professional code covering witness preparation, jury selection, venue surveys, and post-trial interviews, with a grievance committee that investigates complaints from members and non-members.3American Society of Trial Consultants. Professional Code It doesn’t carry the force a state bar’s ethics rules do, but it’s the industry’s own attempt at self-regulation in a field without licensing.
Do They Actually Improve Outcomes?
The honest answer is nuanced. Research suggests scientifically based jury selection methods detect juror bias more accurately than attorneys relying on intuition and courtroom experience alone. One study found that 44 percent of attorneys experienced worse trial outcomes than they had predicted, which points to overconfidence bias and the value of outside perspective.
At the same time, evidence factors account for far more variance in verdicts than juror characteristics do. One widely cited study found that the strength of the evidence explained about 34 percent of verdict variance while juror attitudes accounted for only about 2 percent. No amount of consulting rescues a weak case. Where consultants add real value is in close cases where presentation genuinely matters: identifying the two or three jurors whose biases could tip a verdict, sharpening a theme that makes complex evidence digestible, or catching a weakness in a mock trial that would have been devastating at the real one.
Preparation vs. Coaching
Witness preparation is legal and expected. Witness coaching is not. The line is whether the consultant is helping a witness communicate truthfully and clearly, or influencing the witness to change or fabricate testimony. Legitimate preparation means familiarizing someone with courtroom procedures, practicing composure under cross-examination, and reminding them to answer only the question asked. Those activities make honest testimony more effective without altering it.
Coaching crosses the line when it involves scripting language that doesn’t reflect the witness’s actual recollection, advising a witness to omit relevant facts to create a misleading impression, or suggesting fabricated details. An attorney or consultant who knowingly encourages false testimony under oath risks criminal liability for subornation of perjury, along with sanctions, adverse rulings, and potential disbarment for the attorney involved.
Is Their Work Protected from Discovery?
Generally, yes, if the engagement is structured correctly. Under the Federal Rules of Civil Procedure, a party ordinarily cannot discover documents or tangible things prepared in anticipation of litigation by the other party’s representative, and the rule specifically names consultants alongside attorneys, insurers, and agents.4Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Mock trial results, jury research, witness prep notes, and internal strategy memos generally stay confidential.
The protection isn’t automatic. The materials must be prepared in anticipation of litigation, and the consultant needs to work under counsel’s direction and supervision.5U.S. District Court for the District of Nebraska. Work Product Doctrine for Non-Attorney Produced Documents A report the consultant prepared on their own, without attorney oversight, is much harder to protect. Experienced attorneys handle this by having counsel initiate the retention, writing an engagement letter that states the consultant is assisting with legal advice, and routing communications through counsel. A consultant who never takes the stand is treated as a non-testifying expert, and the opposing party generally cannot compel disclosure of their opinions or the facts known to them. Designating the same consultant as a testifying expert largely strips those protections away, which is why the roles are kept separate.
