Process
How to Arrange a Polygraph Examination in Lithuania
The process begins with a confidential case review. No commitment is required at the enquiry stage.
Initial Enquiry
Send a brief outline of the matter via the contact page, including the issue, the proposed examinee's location, whether an interpreter may be needed, and your preferred Lithuania city and approximate dates.
Confidential Case Review
The proposed case is reviewed for suitability, covering consent, question scope, safeguarding and practical arrangements. You will be advised whether the matter is appropriate and when Lithuania appointments are next available.
Question Formulation
Examination questions are formulated so they are clear, specific, time-bounded where appropriate, and focused on a defined behavioural issue. Instructing parties and solicitors may be involved at this stage.
Examination and Report
The examination is conducted in Lithuania on the agreed date. Results are communicated to the examinee at the end of the session (PENOR) and a written report is prepared for the instructing party in clear professional English.
Please note: We do not claim 100% accuracy, guaranteed truth detection, court admissibility, or government approval for our examinations. Polygraph examination is a structured forensic assessment process. Results should be considered alongside other relevant information and appropriate legal or professional advice.
Credentials
Why Instruct Dr Keith Ashcroft?
Dr Keith Ashcroft is a chartered investigative psychologist and the founder and director of The Centre for Forensic Neuroscience. He provides independent forensic polygraph examinations for private individuals, legal professionals, corporate clients and organisations.
His examinations follow structured forensic methodology, use advanced computerised physiological monitoring technology, and apply Bayesian statistical interpretation of results. Every examination is conducted with clear limitations, voluntary participation, informed consent and careful pre-assessment of suitability.
Written reports are prepared in plain professional English and explain findings, methodology and evidential limitations clearly for instructing parties, solicitors and organisations.
Fully Independent Examiner
No connection to law enforcement, government bodies or commercial testing franchises. Objective and impartial assessment throughout.
Advanced Physiological Monitoring
Professional-grade computerised instrumentation recording multiple physiological channels simultaneously during every examination.
Bayesian Statistical Interpretation
Results contextualised using probability frameworks that account for base rates and case-specific factors, not simplistic pass-fail scoring.
Post-Examination Notification (PENOR)
The examinee is notified of findings at the end of the session, before the formal written report is issued to the instructing party.
Strict Confidentiality
All case information is handled with professional discretion from first contact. Enquiries do not create an obligation to proceed.
Context
Polygraph Examinations and Lithuania
Lithuanian media has discussed both relationship-related polygraph testing and professional forensic practice, indicating that the terminology and private-use concept are already familiar to Lithuanian audiences. Both poligrafas and melo detektorius are used in Lithuanian sources, with poligrafo tyrimas being the more professional formulation.
A number of democratic countries, including the United States and the United Kingdom, use polygraph examinations in carefully defined contexts such as national security vetting and the management of certain high-risk offenders. Different countries have different legal frameworks, and the weight given to polygraph results varies considerably by jurisdiction and context.
Recent Legislative Development
In July 2026, the Seimas of Lithuania voted to extend the circumstances in which polygraph examinations may be conducted, covering individuals applying for access to classified information and certain residence permits. The measure was introduced on national security grounds.
Under the adopted amendments, a negative result does not automatically determine an outcome: decision-makers must consider all available information. This reflects the broader principle that polygraph results are one component of a wider assessment process.
This development reflects the continued recognition of professionally administered polygraph examinations within specific legal and security frameworks. It does not speak to private or civil use.
Information
Frequently Asked Questions
Concise answers for private individuals, legal professionals and companies enquiring about polygraph examinations in Lithuania.
Do you conduct lie detector tests in Lithuania?
Yes. Dr Keith Ashcroft travels from the United Kingdom to conduct independent forensic polygraph examinations in Lithuania. Vilnius is the principal examination location. Kaunas and other cities may be available by arrangement. The examinee does not need to travel abroad.
Where in Lithuania are examinations available?
Vilnius is the principal examination location. Examinations take place in a private, professionally equipped office or another suitable controlled setting arranged for each visit. Appointments in Kaunas and other Lithuanian cities may be considered where there is sufficient demand or a professional instruction that justifies travel. Please enquire with your preferred location.
When is your next visit to Vilnius?
Examination dates in Lithuania are arranged in response to confirmed or anticipated demand. To enquire about the next available Vilnius appointment, please contact the Centre with a brief description of your matter and your preferred dates. You will be advised on availability following an initial case review.
Can the examination be conducted in Lithuanian?
The examination is conducted in English by Dr Keith Ashcroft. Where the examinee's English is limited, interpreter assistance can be arranged. The interpreter supports precise communication throughout the session, but the examiner remains responsible for procedure, question formulation and all professional decisions. Interpreter requirements should be discussed at the case review stage.
Can an interpreter assist with the examination?
Yes. Interpreter assistance can be arranged where the examinee requires support in Lithuanian or another language. Interpreter requirements must be confirmed before the examination is accepted. The interpreter facilitates communication but does not take any role in the professional examination process itself. Interpreter arrangements are discussed at the case review stage so that precise communication can be planned in advance.
How much does a polygraph examination in Lithuania cost?
Fees for examinations conducted in Lithuania reflect the costs of the examination itself, preparation, reporting, travel and any interpreter arrangements. A fee indication will be provided following the initial case review, once the scope and location of the examination have been established. For general information about examination costs, see our polygraph cost page.
Can companies arrange several employee examinations during a single visit?
Yes. Where a company or organisation requires more than one examination, it is usually more practical and cost-effective to group them into a single Lithuania visit. This requires advance planning, suitability review for each proposed examinee and confirmed question formulation for each case. Corporate enquiries should be made as early as possible to allow scheduling.
Will I receive a written English-language report?
Yes. A written report is prepared in clear professional English for the instructing party following every examination. The report describes the examination process, the physiological data recorded, the interpretation of results and the evidential limitations of the assessment. At the end of the examination session, the examinee receives a verbal Post-Examination Notification of Results (PENOR) before the formal report is issued.
