Independent. Rigorous. Court-Ready.
Specialist expert witness psychological assessments and reports for family, civil and criminal proceedings.
What we offer
When the courts require independent psychological expertise, the quality, credibility and clarity of the expert's report is paramount. At Abacus Psychology Service, our Forensic, Clinical and Counselling Psychologists provide expert witness assessments and reports across family, civil and criminal law — combining clinical rigour with clear, accessible communication that serves the needs of the court. All of our expert witnesses are HCPC-registered, hold current DBS clearance, and have significant experience providing evidence in a range of legal settings.
Why Psychological Expert Evidence Matters in Court
Psychological factors are relevant to an enormous range of legal proceedings — from questions of mental capacity and parenting ability in family cases, to psychiatric injury claims in civil proceedings, to issues of culpability and risk in criminal matters. A high-quality, independent expert psychological report provides the court with an objective, evidence-based analysis that would otherwise be beyond the reach of legal professionals alone. At Abacus, we take our duty to the court seriously. Our reports are thorough, well-reasoned and written to the standards required of expert witnesses in England and Wales.
