02 When Commissioned

Three stages where
a coercive control report is critical.

01

Pre-charge decision

Our chambers accepts instructions from the Crown Prosecution Service to assess whether the alleged behaviour meets the s.76 threshold of “serious effect” under Serious Crime Act 2015. Reports address the cumulative impact of controlling behaviours, supporting charging decisions where evidence is borderline.

02

Family proceedings

In Children Act 1989 proceedings, our coercive control assessment reports evaluate the psychological harm to children exposed to domestic abuse. Reports are structured to meet FPR 25 requirements, addressing the welfare checklist and supporting findings of fact under Re W.

03

Civil compensation claims

For civil claims involving psychological injury, our reports link coercive control to recognised psychiatric disorders, addressing causation under the Bolam test. Reports are prepared for CICA applications, redress schemes, and personal injury claims where psychological abuse is the primary harm.

04 Methodology

How our assessments
are conducted.

Our members conduct coercive control assessments using trauma-informed methodologies, ensuring compliance with CPR Part 35 and the Civil Justice Council 2014 Guidance. Each step is documented to withstand scrutiny in joint expert discussions or cross-examination.

  1. 01

    Records review

    Full review of police reports, GP records, mental health notes, and any prior statements. Material entries are identified in the report to support the temporal link between coercive behaviours and psychological symptoms.

  2. 02

    Clinical interview

    Structured interview lasting 2–3 hours, conducted at a venue of the claimant’s choice. The expert uses open-ended questions to elicit patterns of coercive control, with breaks offered to manage distress.

  3. 03

    Standardised tools

    Where clinically indicated, instruments such as the Controlling Behaviours Scale or PTSD measures are administered. Selection and rationale are documented in the report to meet CPR 35.6 requirements.

  4. 04

    Formulation

    Clinical formulation linking the coercive behaviours to the claimant’s current presentation. The expert addresses alternative explanations for symptoms, such as pre-existing conditions or unrelated stressors.

  5. 05

    Report drafting

    The report is prepared in compliance with Practice Direction 35, with clear signposting of key findings. Opinions are supported by reference to the evidence base and the expert’s clinical experience.

06 Key Considerations

Questions from
solicitors instructing our chambers.

What is the legal threshold for coercive control under s.76?

Both. The Serious Crime Act 2015 s.76 requires proof that the perpetrator’s behaviour had a “serious effect” on the victim, either by causing fear of violence on at least two occasions or by causing serious alarm or distress affecting daily activities. Our reports address this threshold by linking specific behaviours to psychological harm under ICD-11 or DSM-5-TR.

Can a coercive control expert witness report be used in family court?

Yes. Our reports are prepared in compliance with FPR 25 and Practice Direction 25B, addressing the welfare checklist under Children Act 1989. They evaluate the psychological impact of coercive control on both the primary victim and any children exposed to the abuse.

How do your experts address the overlap with modern slavery?

By clinical formulation. Coercive control is recognised as a mechanism underpinning labour, sexual, and criminal exploitation. Our reports distinguish between domestic abuse and exploitation-related coercion, addressing patterns of compliance and delayed disclosure where relevant.

What records are required for a coercive control assessment?

Core records include: police incident logs, GP and mental health records, any prior statements, and records from refuges or domestic abuse services. Where available, text messages, emails, or social media evidence are reviewed to corroborate patterns of coercive behaviour.

Can your experts assess historic coercive control cases?

Yes. Our members assess historic cases where psychological harm persists, addressing limitation under s.33 Limitation Act 1980 where applicable. Reports link past coercive behaviours to current psychiatric symptoms, supported by clinical evidence.

Do your reports comply with CPR Part 35?

Yes. All reports include the CPR 35 declaration, statement of truth, and confirmation of independence under CPR 35.3. Our experts are available for joint discussions under CPR 35.12 and to respond to Part 35 questions within the prescribed timeframe.
