Domestic Abuse Allegations & Credibility Assessment
Forensic Investigative Service — Disputed Allegations & Credibility Assessment
A specialist forensic service evaluating the credibility of disputed domestic abuse allegations — including physical violence, coercive control, psychological abuse, and financial abuse. This is not a commercial lie detector service. Examinations do not determine guilt or innocence.
Findings are reported as investigative information to assist solicitors, investigators, and private clients — not as evidence of fact.
When Credibility Becomes Central
In many domestic abuse cases, independent evidence is limited. Accounts conflict. Where there are no witnesses, no forensic material, and no digital record, credibility assessment becomes the pivotal investigative question.
The Centre for Forensic Neuroscience provides domestic abuse polygraph examinations for solicitors, barristers, defence teams, and private clients. Unlike many commercial providers, every examination is conducted personally by Dr Keith Ashcroft — a chartered investigative psychologist and trained forensic polygraph examiner.
Scientific & Professional Position
What a Polygraph Examination Does and Does Not Do
Scientific Position Statement
A polygraph examination does not determine whether abuse occurred and does not establish guilt or innocence. It records cardiovascular, respiratory, and electrodermal responses while an individual answers specific questions about disputed acts. The data are interpreted by a forensic examiner using validated scoring methodology.
Findings form one component of a wider investigation. They do not replace witness evidence, documentary evidence, or forensic material, and must not be used as the sole basis for any significant decision.
Physiological Data
Cardiovascular, respiratory and electrodermal responses recorded and evaluated using validated scoring techniques
Validated Methodology
Techniques and practices consistent with current American Polygraph Association standards
Investigative Support
Results inform rather than replace the judgement of investigators, legal advisers and decision-makers
Case Types
Types of Cases Considered
Domestic abuse, as defined under UK statute, encompasses physical violence, coercive and controlling behaviour, psychological abuse, and financial abuse. Examinations address specific, clearly defined behavioural allegations — not opinions or generalised suspicions.
Suitability is assessed individually. Not all matters will be suitable.
Assault Allegations
Specific disputes concerning alleged physical assault, battery, or unlawful force within a domestic or intimate setting, where a clearly defined incident is identified.
Historical Domestic Abuse Allegations
Past allegations may be suitable for examination where the relevant acts are sufficiently specific and temporally defined. Where allegations are diffuse, a Statement Verification approach may be more appropriate.
Coercive Control Allegations
Specific disputed instances of controlling or coercive behaviour, where discrete acts can be identified and formulated into valid examination questions. Broad pattern allegations require careful case assessment.
Psychological Abuse Allegations
Specific disputed incidents of intimidation, threats, or demeaning conduct may be suitable for examination where the relevant behaviour can be precisely identified. Examinations address clearly identifiable behavioural allegations only — not subjective experiences or states of mind.
Financial Abuse Allegations
Disputed allegations concerning financial exploitation, misappropriation, or economic control within a domestic relationship may be suitable where the specific transactions or acts can be clearly identified.
Criminal Defence
Defence solicitors and barristers may instruct an examination as part of an investigative strategy in cases where a client disputes specific allegations. Results are reported as investigative information, not evidence.
Family Proceedings & Child Contact
Where disputed domestic abuse allegations arise in the context of family proceedings, child contact applications, or residence disputes, a specific-issue polygraph examination may assist solicitors when evaluating disputed factual allegations. Instructions from family law solicitors are accepted in appropriate cases.
Regulatory Investigations
Regulatory bodies and professional standards panels in healthcare, education, social care, licensing, and related sectors may, in appropriate circumstances, commission a credibility assessment examination as part of a wider investigative or fitness-to-practise process.
Professional Disciplinary Matters
Solicitors, HR professionals, and disciplinary panels dealing with allegations of interpersonal misconduct may instruct an examination as part of a structured investigative process, subject to appropriate safeguarding and voluntariness considerations.
Referrals & Instructions
Who May Instruct an Examination
Examinations may be instructed by any of the following. Self-referrals from private individuals are accepted following an initial consultation to confirm suitability.
Solicitors & Legal Teams
Legal representatives in criminal defence, family law, and civil matters. All instructions are subject to standard suitability and safeguarding assessment.
Polygraph services for solicitors arrow_forwardPrivate Individuals
Either party to a dispute may enquire directly. The person to be examined must participate voluntarily and provide independent informed consent.
Corporate Investigators & Regulators
Professional regulators, disciplinary panels, and corporate investigation teams may instruct examinations where the matter falls within the scope of this service.
Defence Teams
Defence solicitors and counsel may commission an examination as part of an investigative strategy. Findings are presented as investigative data, not as evidence of innocence.
Pre-Examination Process
Suitability Assessment
All prospective examinees are subject to a structured pre-examination screening process before any appointment is confirmed. This process addresses the following:
- Medical suitability, including relevant conditions and medications
- Psychological suitability and current mental health status
- Safeguarding considerations and risk assessment
- Understanding of the examination process and its limitations
- Confirmed voluntary participation, free from coercion or pressure
- Interpreter requirements, where applicable
Forensic Methodology
Question Formulation
The validity of any polygraph examination depends on the quality of its questions. In domestic abuse cases every question must meet strict criteria.
One Specific Behaviour
Each question concerns a single, precisely identified act. Compound questions referring to multiple alleged behaviours are not used.
One Identifiable Incident
Questions must refer to a specific occasion that can be identified in time and circumstance. Vague or rolling time periods are not used without careful qualification.
No Embedded Assumptions
Questions must not presuppose facts that are themselves in dispute. Assumptions embedded in questions compromise the scientific defensibility of the examination.
No Emotional Wording
Emotive, prejudicial, or inflammatory language is excluded from examination questions. Neutral, behavioural terminology is used throughout.
No Opinions Elicited
Questions address actions and conduct, not states of mind, opinions, beliefs, or relationship characterisations.
Agreed Before Testing
All examination questions are reviewed with the examinee during the pre-test phase. No examination proceeds until the examinee understands and agrees to each question.
Examples of Suitably Formulated Questions
The following are illustrative examples only. They do not represent questions that would be used in every case, nor do they constitute a template. Every examination requires bespoke question formulation based on the specific facts of the matter. Names and dates are entirely fictitious.
“On 12 March 2026, did you deliberately strike Sarah Jones?”
“During the incident at your home on 12 March, did you intentionally prevent Sarah Jones from leaving the property?”
“Since January 2026, have you deliberately made threats of physical violence towards Sarah Jones?”
Examples illustrate structure only. All questions are bespoke to the specific matter. Names and dates are fictitious.
Alternative Methodology
When Statement Verification May Be Preferable
Where allegations span extended periods, involve multiple incidents, or are described in diffuse terms, a Statement Verification Examination may be more appropriate than specific-issue polygraph testing. This approach analyses the consistency and content characteristics of a written account against established forensic criteria.
Read about Statement Verification ExaminationsStatement Verification May Be Considered When:
- Allegations span extended periods without specific, datable incidents
- Multiple overlapping incidents cannot be individually particularised
- A written account or statement is available for structured analysis
- Medical or psychological factors make physiological testing inadvisable
- A complementary methodology alongside physiological polygraph is required

Safeguarding
Safeguarding Principles
The welfare of all individuals is the primary consideration. The following principles apply to every case.
- Voluntary participation is absolute. Examinations proceed only where participation is entirely free from coercion or pressure.
- Unsuitable cases are declined. Where safeguarding concerns are identified, the examination will not proceed. No adverse inference is drawn.
- Both parties are considered equally. This service neither assumes that persons alleging abuse should be examined nor that persons accused should not be. Every case is assessed individually.
- Right to withdraw at any time. Withdrawal has no adverse consequence and does not form part of any report.
