For courts and legal professionals

This register can help you to quickly locate a suitable psychologist who is both knowledgeable and experienced in expert witness work across a range of legal contexts, including:

• Civil, Family, or Criminal proceedings
• Magistrates' or District courts
• Tribunals and panel hearings

What is an expert witness?

Although there is no legal definition of an expert or expert witness, the society's definition is:

 "An expert is a person who, through specialist training, study, or experience, is able to provide a court, tribunal, or hearing with relevant scientific, technical, or professional information or opinion, based on skills, expertise, or knowledge, that is likely to be beyond the experience and knowledge of the representing lawyers, judge, jury or panel." 

- Psychologists as Expert Witnesses: Best practice guidelines for psychologists (2021)

What is a psychologist in this context?

Here, "psychologist" refers to:

• Practitioner psychologists: Psychologists who are registered with the HCPC. HCPC registration authorises the use of a protected title (including "Practitioner Psychologist") and provides governance regarding the professional practice of registered individuals (see Why your registration matters | The HCPC). For this register, HCPC regulation gives assurance that a psychologist is accountable for their practice in offering clinical assessments.
• Academic psychologists: Chartered by the British Psychological Society (BPS) and recognised for their research expertise, though not necessarily involved in clinical assessments.

When choosing an expert witness, note that HCPC-registered psychologists bring clinical experience essential for clinical assessments, while chartered academic psychologists offer specialised research insights.  

This register allows only HCPC-registered psychologists to offer clinical assessments in their biographies to ensure that people have recourse to the regulator (HCPC) where there are concerns about the fitness to practise of members listed on the register.

This distinction between research expertise and psychological services is in keeping with the Re C judgment (EWHC 345 (Fam) 2023) and in line with the Family Procedure Rule Committee proposals (currently in consultation) to require the courts to engage regulated psychologists as experts.

All experts are responsible for the accuracy of their profiles on the Register.

Maintaining your registration

The requirements to maintain registration are in place to ensure that registrants continue to meet the eligibility criteria, and are up to date with developments relevant to expert witness work. 

Registrants must:

• Hold current indemnity insurance covering your expert witness work;
• Have no adverse findings or unresolved complaints of relevance from an employer, HCPC, the courts or other competent authorities;
• Maintain HCPC registration (for those offering the services of assessment formulation and diagnosis);
• Engage in CPD relevant to your expert witness activities

You'll receive a reminder one month before your registration is due for renewal. If we don't receive your renewal payment your registration will lapse and you'll no longer appear on the register. We operate a no refund policy. Once registration is paid for the period of one year it's non-refundable.  

By paying your registration fee and when renewing your registration each year you confirm that you continue to meet the eligibility requirements to be registered on the Register of Expert Witnesses.

If at any point you cease to meet these requirements, you should notify the Membership team by emailing [email protected] for advice. In the case of receiving a complaint you should contact the complaints team by emailing [email protected] for advice. We will assess the situation and if you no longer meet the requirements for registration, you may be removed from the register.

These requirements not only keep your skills current but also strengthen the overall value and trust in the register.

Continuing professional development (CPD) requirements

Acceptable CPD includes conferences, workshops, supervision, research, service development, and court advisory roles.

All activities should demonstrate learning outcomes and practical implementation of learning. Registrants should pay particular attention to changes in court procedures or the issuing of judgements that may impact on how an expert witness is expected to make their contribution to the courts.

As members of the society, you can access the BPS MyCPD platform to record your CPD. The MyCPD platform supports you to plan your development and record activities, including the upload of evidence e.g. certificates and reflect on your learning. You can also generate reports on all of the content

Annual declarations and audits

At renewal of their annual subscription, registrants must declare that they still meet the requirements to maintain their registration.

• On an annual basis, 20% of randomly selected registrants will be asked to provide evidence of their indemnity insurance
• On an annual basis, 20% of randomly selected registrants will be asked to provide evidence of CPD activities and reflection on those activities for review by peers from the register

Making a complaint

We encourage an informal approach to resolving any concerns as the quickest route in the first instance, where it is appropriate. If you have any concerns about a registrant's conduct, we recommend speaking directly with the individual where possible. However, if the matter requires further action:

• Immediate Danger - Please call the police.
• Professional Conduct Concerns - If you suspect unprofessional behaviour please raise the matter with the registrant's employer, if applicable.
• Quality of Expert Reports - Concerns regarding the quality of an expert report should be addressed through your legal representative and brought to the attention of the court.
• Clinical Practice - Any concerns related to the clinical practice and services of assessment, formulation and diagnosis should be reported directly to the HCPC.

Complaints submitted to the Society will be reviewed by our Complaints Team, who will determine whether the matter should be handled by the HCPC, the courts, or under our Member Conduct Rules. You can raise your concerns through our complaints process. 

Upholding excellence through robust governance

Our register is maintained with strong oversight to ensure that expert witness practice remains of the highest standard. 

Key governance features include:

• Standards and Competencies - The required areas of expertise (from understanding court procedures to producing compliant reports) have been approved by the Practice Board and are regularly reviewed by the Expert Witness Advisory Group.
• Continuous Improvement - Annual audits and renewal declarations ensure that registrants meet the required standards. Any shortfall in CPD, indemnity insurance, or supervision may result in removal from the register.
• Transparent Reporting - The annual renewal process is reviewed by the Member Board, informing any necessary adjustments to admission criteria, CPD expectations, and audit processes.
• Collaboration and Accountability - Oversight is provided by the Member Board, Practice Board, and EWAG. This collaborative approach guarantees that the register stays current, inclusive, and aligned with both legal expectations and best practices in psychology.
