About Trish Guise MSc MBA – Expert in Coercive Control
Trish Guise is a forensic behavioral scientist who specializes in the psychology of coercive control, family violence and post-separation abuse. She is the Founder and Principal of Forensic Coercive Control Solutions and a Research Associate with the Directorate of Psychology and Sport at the University of Salford.
She holds a Master of Science in the Psychology of Coercive Control with distinction from the only graduate program in the world dedicated exclusively to this area.
Her work focuses on identifying patterns of coercive control across documented behavior and communication. She analyzes documentary evidence within family, civil, and criminal law, workplace, and institutional settings,
She works with lawyers, courts, and professionals to identify patterns of coercive control and ensure they are clearly understood within the available evidence. Trish also assists individuals with co-parenting and preparation for mediation.
When Counsel Typically Retains Me
I am typically retained in matters where:
• There is a large volume of documentary evidence, but the case remains unclear
• The matter is framed as conflict, but the pattern does not align
• A client is unable to clearly articulate their experience despite consistent reporting
• Coercive control is alleged, minimized, or contested
• Early decisions are required regarding case framing or process selection
• A parenting assessment has been proposed and its appropriateness is uncertain
• Behaviour must be assessed across time, not through isolated incidents
These matters are not difficult because evidence is lacking.
They are difficult because the pattern has not yet been clearly identified.
What I Do
I conduct structured, pattern-based analysis of documentary evidence to identify coercive control and related behavioural dynamics across time.
This includes:
• Organizing and synthesizing documentary records
• Identifying patterns of coercive control and post-separation abuse
• Distinguishing coercive control from conflict
• Assessing escalation and behavioural consistency
• Examining litigation and systems-based abuse
• Mapping impact on individuals and, where relevant, children
My role is not to make findings of fact or assess credibility.
My role is to assist the court in understanding behavioural patterns within the available evidence.
Why This Matters
When coercive control is not identified early:
• Matters may be incorrectly framed as mutual conflict
• Inappropriate processes may be selected, including mediation where it may not be suitable
• Patterns of behaviour may be minimized or overlooked
• Decisions may be made without a clear understanding of context, risk, and impact
Early, structured analysis supports more accurate case framing and more appropriate process decisions.
Services
Expert work includes the preparation of independent reports and the provision of testimony in matters involving coercive control.
This may involve case specific opinions, based on a structured analysis of the available record to identify patterns of behaviour across time, or subject matter testimony, which provides the court with research based context on coercive control and its impact on parenting, decision making, and child safety.
Domestic violence risk assessments are also available. These are structured, interview based assessments focused on identifying reported risk indicators and supporting safety planning. They do not include forensic verification or independent findings for court.
Litigation support includes structured case preparation in matters involving coercive control or family violence across family, civil, and criminal law contexts. This work focuses on the review and organization of information, identification of patterns of behaviour across time, and clarification of key issues relevant to the case.
Support is provided to clients and their lawyers in preparing information for use in court, including organizing documentation, identifying gaps, and strengthening how information is communicated within the legal process.
This is a non-testimonial, advisory service. It does not include legal advice or independent expert opinions for court.
Trish provides specialized training for professionals who work with cases involving allegations of coercive control, family violence, and complex post separation dynamics.
Her training is skills based and focused on real world application. Participants learn how to identify patterns of coercive control across time, understand how these dynamics are often misinterpreted, and respond in ways that support safety and stability.
Sessions are grounded in case based examples and tailored to the audience, including lawyers, court professionals, service providers, and individuals.
Coaching includes structured support for individuals navigating divorce, mediation, and parenting matters where coercive control or complex dynamics may be present. This work focuses on understanding the situation, developing practical strategies, and preparing for key decisions and interactions.
Support may include divorce coaching, pre-mediation preparation, parenting and co-parenting strategies, and guidance on communication and working effectively with lawyers and other professionals.
This is a non forensic service. It does not involve legal advice, formal assessments, or expert opinions for court.
