Truth Verification Process

“Using interdisciplinary methods of Polygraph (Physiological) measuring and Psycho-Analysis through Forensic Psychology, the Private Lie Detector Test is able to verify the truth based on the integration of multiple factors. A high level of accuracy is only possible through a unique combination of advancements in polygraph equipment and expert level psychology in deception. We regularly have a heavy caseload of conducting confidential criminal and legal tests, and our team of professional examiners draw upon the wealth of their experience to produce quality results.”

We approach every case with the integration of a suitability check to confirm that the private lie detector test is necessary and that the client has full comprehension of what the process entails. Most individuals who seek evaluations have no prior experience with the process, so it is crucial that our services execute a high level of transparency and assistance.

Operating Framework

If our professional examiners deem that it is viable and appropriate to do so, we can conduct polygraph examinations at residential addresses, so long as certain environmental controls are met as requested by the examiner. These controls are required so as to allow for appropriate testing conditions, including the avoidance of potential distractions, so that the examiner can provide evaluation results that reflect optimal accuracy. Client confidentiality is of utmost importance to our team of professionals. We do not disclose information concerning the controlled locations until the reservation request is confirmed. At that time, this information is only provided directly to the client. To verify his or her identity, the individual must provide a government issued identification, such as a Passport, Photo ID card or Driver’s License, upon arrival.

Please be aware that our evaluations require mutually professional demeanor, and if any individual shows aggression or unbecoming behavior towards an examiner, we reserve the right to terminate the examination immediately with no refund.
Also, any attempt to bribe, influence, threaten or make a deal with the examiner will result in the local police being notified of such behavior. If the examiner is exposed to any criminal behavior or suspicion of criminal activity, we reserve the right to terminate the examination. All fees linked to the evaluation are entirely non-refundable if the examination is terminated due to criminal activity.
Also, if the examiner suspects any form of domestic violence, these suspicions will be reported to the appropriate authorities.
Furthermore, any individual who attempts to trick or cheat the test will be met with a single warning. Additional attempts will result in an invalidated evaluation with no refunds provided.

Once a venue date and time has been confirmed, it is your responsibility to arrive on time to take part in the examination. Delayed arrival may not be accommodated.
If there is any threat of violence to the examiner or the test participant during the examination, the examiner has the right to terminate the examination immediately with no refunds provided.

Our assessment methods require that only close-ended, issue-specific questions may be included in the examination. Questions concerning beliefs, opinions or intentions are prohibited. Rather, questions must be formulated around facts, events and true statements. During the polygraph examination, the examiner may ask up to 8 questions, 1-3 of which will be directly linked to the case at hand. An increased ratio of questions relating to the case may undermine the individual’s credibility, resulting in lowered accuracy of results.

During the polygraph test, only the examiner and the individual being tested will be present. No other individual is allowed in the room at that time. No third parties are to be present during the testing. However, third parties may be present during the pre-test interview, during which the questions and case issue may be discussed.

On successful completion of the examination, the examiner will share a fully verified, written report reflecting the polygraph results with the person who initiated the original reservation. This will be provided either via email or post in a confidential manner, depending on the client’s requests. While the results may be shared with the client verbally, the verifiable, written results will not be made available on the day of the test, unless explicitly specified by the examiner. The results will also be made available to the person being tested, if approved by the client who initiated the reservation.

Any breach of the Terms and Conditions may result in the cancellation of testing without refund.

Payment & Cancellation Conditions

As stated, a non-refundable reservation fee will secure your request for a polygraph examination. Once this payment is processed, you will receive a pre-examination assessment via email and text message (SMS) to be returned within 24 hours. Completion of this pre-examination assessment will enable billing of the remaining balance. We will then arrange the location and time of your examination. Immediately prior to the test, you will meet with the examiner at the venue to provide additional details concerning the case. Based on the information provided, the examiner will formulate appropriate questions that will be used in the examination.
Please note that we must receive full payment 48 hours before the polygraph examination is to take place. We will actively attempt to contact you by phone and email provided before this deadline. Failure to respond to our communication attempts within the 48 hour period prior to examination will result in complete termination of the booking without refund. In the event of complete termination due to lack of response and/or payment by the client, Lie Detector Test USA will keep the fees already paid to offset the costs incurred by Lie Detector Test USA and the examiner assigned to the case.

If the client wishes to cancel the polygraph examination prior to the 48 hour period preceding the agreed upon reservation time, then the amount already paid less the non-refundable reservation fee will be refunded, so long as the full balance has already been paid by the client. In any case of cancellation by the client, the reservation fee remains non-refundable and will not be refunded to the client. However, if the cancellation is made prior to the 48 hour period, the non-refundable reservation fee may be transferred to an alternative date, time, and/or location with no loss of payment. In specific situations in which our organization agrees, cancellation notifications made prior to the 48 hour window that are rescheduled within 14 days of the original examination date may result in transfer of the reservation fee to the new examination reservation. In rare circumstances, cancellation notifications that are made with a minimum notice of 48 hours may result in a refund of the balance already paid less the reservation fee, which is non-refundable.

For reservations that request a polygraph examination on the same day or the following day, the balance must be paid in full immediately upon reservation. The pre-examination assessment form must also be completed and submitted on the same day as the initial reservation request. Failure to comply with any of the terms and conditions will result in complete cancellation of the scheduled examination. We reserve the right to offer alternative dates, times, and/or locations if the examination cannot be conducted at the original locale agreed upon due to unforeseen circumstances. In the event that an examination requires rescheduling for date, time, and/or location, we will provide adequate notice to the client who has reserved the case. All information collected during standard operating procedures, including data, charts, documents and video recordings, remains the property of the examiner and will be handled in accordance with our responsibilities as outlined under the Data Protection Act 1998. N.B.
Please be aware that once a reservation is arranged, the non-refundable reservation fee is retained to cover the cost of the examiner’s time, resources and loss of business, as a result of the examiner’s inability to arrange any other polygraph examinations on the requested date and time.
