In Henley-on-Thames, our family lie detector service uses P300 EEG to assess recognition of key details in theft, inheritance and abuse cases — not just changes in heart rate or breathing.
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 Henley-on-Thames and Oxfordshire.
We speak with you confidentially about your Henley-on-Thames or wider Oxfordshire family situation, what has happened and what you need to prove. Together we decide whether a P300 EEG lie detector test is appropriate.
Our examiner designs clear, yes/no questions focused on the key issues. These are shared and agreed in advance so everyone in Henley-on-Thames and Oxfordshire knows exactly what will be asked during the test.
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 Oxfordshire family cases.
After the test, you receive a clear explanation of the findings and a written report which can be shared with your Henley-on-Thames or Oxfordshire solicitor, mediator or kept private within the family.

Common questions about using P300 EEG brain-wave testing to resolve family disputes, theft accusations and inheritance issues.
P300 EEG is ideal wherever truth between family members is disputed and emotion is high. We regularly support:
P300 EEG results are not formally admissible as standalone evidence in UK courts. However, many families use the certified report to support solicitor-led negotiations, mediation or private discussions. The scientific objectivity of the result often helps all parties accept the outcome. We provide court-ready documentation on request.
Not always. In some disputes only one key person is tested — for example, someone accused of theft. In more complex situations, several family members may be tested to build a complete picture. We advise during your consultation which approach is most appropriate for your case and budget.
Individual tests start from £499. Multi-person testing typically starts from £599, with tailored pricing for complex inheritance or business cases. Same-day or urgent appointments are available from £599 depending on location and availability.
Yes. All cases are handled with strict confidentiality and GDPR-compliant data protection. We only share results with the booking party or your nominated solicitor or mediator. No information is released to other family members or third parties without your written permission.
Alongside your written report, you receive a clear explanation of the findings and next-step guidance. Many families use the results for solicitor-led negotiations, mediation, formal proceedings or private discussions to rebuild trust or set boundaries. We can also provide additional documentation or follow-up testing if your legal team requests it.
