Forensic Polygraph Examination
An independent polygraph examination for legal matters — instructed by solicitors, private clients and parties to a dispute. It tests an account, supports case strategy and helps resolve conflicts out of court. A polygraph is not admissible as courtroom evidence; here it's an investigative and decision-support tool, run to a rigorous standard in 40+ countries.
In short: a forensic polygraph is an independent examination used in a legal context — to test a client's account, pressure-test a case theory or move a dispute toward settlement. It is taken voluntarily, and while it is not admitted as evidence in most courts, it is a widely used tool for defence teams and private parties.
What a forensic polygraph examination does
Where a case turns on one person's version of events, an independent examination gives counsel an objective read on it before deciding how to proceed.
The result helps a defence team weigh options, prioritise lines of enquiry and advise a client with more confidence — an investigative aid, not a verdict.
In commercial, partnership and family matters a neutral examination can confirm or dispel an allegation, opening the way to a resolution without litigation.
Who instructs a forensic polygraph
Defence and litigation teams testing a client's account, sounding out a case theory and shaping strategy before trial or settlement.
Businesses and individuals in commercial or partnership conflicts who want an allegation over money, deposits or accounts objectively addressed.
Individuals seeking to clear their name of a serious allegation, or to weigh a contested point in a family or financial matter impartially.
In each case the examination is arranged around the specific issue, the questions are agreed in advance, and the person examined takes part voluntarily and with full written consent. The examiner remains neutral throughout — the aim is an objective read, not a result to order.

Admissibility, consent and confidentiality
The value of a forensic polygraph lies in how it's used — as an independent investigative and decision-support tool, not as proof at trial. The essentials:
- Polygraph results are not admitted as standalone evidence in the UK, Ireland and most jurisdictions. Courts have consistently declined to treat them as proof of truth or deception
- Their real use is for the parties themselves: to test an account, guide a defence strategy, support pre-action and settlement discussions, and inform a private decision
- The examination is voluntary and requires the examinee's written, informed consent; it is arranged around a defined issue with questions agreed in advance
- The examiner is independent and impartial — the report reflects the recorded responses, not the instructing party's preferred outcome
- Everything is handled in strict confidence, under a mutual NDA where required, and released only to those the client nominates. Personal data is processed under the applicable privacy law (UK/EU GDPR, PIPEDA and others)
A forensic examination is priced by format and location — from $205 online and from $250 in person — with the exact figure confirmed once the issue and format are clear. Testing in a second language adds about $95. The full breakdown is on our pricing page, and the first consultation is free.
What clients say
"I instructed an examination to test my client's account before deciding on strategy. They were clear it isn't admissible, which I valued, and the report was reasoned and impartial. It genuinely shaped our approach."
"A partnership row over accounts that was heading for court. A neutral examination confirmed the position and helped both sides settle. Professional and completely confidential."
"I wanted to clear my name of a serious accusation. The examiner was impartial and thorough, and the written report gave me something objective to stand on. Handled with real care."
"Used to weigh a contested point impartially in a family matter. Sensitive and discreet throughout. Arranging a suitable time took a little patience, but the outcome helped."
Forensic polygraph examination explained
A forensic polygraph examination sits at the point where a factual question meets a legal one. A solicitor may need to know whether a client's account holds together before committing to a strategy; parties to a commercial or family dispute may want an allegation objectively addressed before it reaches court; an individual may want to clear their name of a serious charge. In each situation an independent examination provides an objective read on the specific issue — arranged around agreed questions, taken voluntarily, and delivered as a reasoned written report.
What sets forensic work apart is neutrality. The examiner is instructed to establish an objective result, not to produce a convenient one, and the report reflects the recorded physiological responses and the methodology behind them. That independence is precisely why defence teams and disputing parties find it useful: a result that simply confirmed whatever the instructing side wanted would carry no weight, whereas an impartial examination can genuinely inform a decision, strengthen or reconsider a strategy, or unlock a settlement.
It is equally important to be clear about the limits. In the UK, Ireland and most other jurisdictions, polygraph results are not admitted as evidence in court, and a forensic examination does not determine guilt or take the place of legal advice or a judicial process. Its role is investigative and advisory — a tool that helps the people involved see a matter more clearly. Used that way, with consent and in confidence, it is a valuable part of how many legal and private disputes are worked through.
