How a P300 Family Lie Detector Test Works in Cambridge, Cambridgeshire

We follow a structured, step-by-step process to make sure each family lie detector test is fair, reliable and as stress‑free as possible for everyone involved across Cambridge and Cambridgeshire.

1. Private Consultation

We speak with you confidentially about your Cambridge or wider Cambridgeshire family situation, what has happened and what you need to prove. Together we decide whether a P300 EEG lie detector test is appropriate.

2. Question Design

Our examiner designs clear, yes/no questions focused on the key issues. These are shared and agreed in advance so everyone in Cambridge and Cambridgeshire knows exactly what will be asked during the test.

3. P300 EEG Testing Session

During the session, we place non‑invasive sensors on the scalp and present a series of neutral and relevant items. The P300 response shows how the brain reacts to recognised information in real Cambridgeshire family cases.

4. Results & Written Report

After the test, you receive a clear explanation of the findings and a written report which can be shared with your Cambridge or Cambridgeshire solicitor, mediator or kept private within the family.

No Wires. No Straps. Just a Headband.

A traditional polygraph straps sensors to your chest, fingers, and arm — measuring sweat, breathing, and blood pressure while you sit in stress. Our P300 EEG test uses a single lightweight headband that reads brain activity directly. No discomfort, no intimidation, and it's over in under 90 minutes.

Family Lie Detector Test FAQ

Common questions about using P300 EEG brain-wave testing to resolve family disputes, theft accusations and inheritance issues.

Disputes between adult family members about specific facts: missing money or valuables, inheritance and will disagreements, suspected financial abuse of an elderly relative by a family member or carer, family business shortfalls and disputed loans. We test adults only, never children, and we do not take cases that should be handled by safeguarding services or the police.

No. Lie detector reports are not admitted as evidence in UK courts. Families use the written report privately: to settle a dispute between themselves, or to share with a solicitor or mediator who can decide what weight to give it.

Laboratory research on the P300 recognition method reports accuracy of roughly 80 to 95 percent, with more limited field validation. Those are published research figures, not results from our own testing, and no test is perfect. The test measures whether you recognise specific details, which is less dependent on nerves than a polygraph.

Not always. Sometimes one person is tested; in other disputes several adults are tested in the same visit, each with a separate report. Every person tested must agree to it voluntarily. We advise on the right approach at your free consultation.

£499 per test, including the examiner visit anywhere in Cambridge, the test and the written report. Each additional person tested in the same visit is £399. Same-day appointments are available at the same price if you book before 1pm.

Yes. Reports are sent only to the person who booked, or to a solicitor or mediator they nominate. Nothing is shared with other family members or third parties without written consent, and data is handled under our GDPR processing notice.
