In addition to therapeutic work, Dr Kat Aguilera provides independent expert witness assessments for adults and adolescents.

These assessments offer clear, evidence-based evaluation of psychological functioning for legal proceedings, including family court, civil psychological injury claims, and employment tribunals, or for investigation and clarification of mental health issues. Each assessment is conducted impartially, drawing on clinical expertise to deliver a balanced and reliable professional opinion.

Types of Expert Witness Assessments

All of my psychological assessments are tailored to the specific requirements of legal, employment, and civil contexts. Each assessment is carried out with impartiality, clinical accuracy, and a clear focus on the questions posed by instructing parties. Below are the key areas in which I offer expert witness evaluations:

Employment Tribunals Assessments

I provide expert psychological assessments to support workplace tribunal cases involving stress, discrimination, bullying, harassment, and fitness to work. My reports offer clear, evidence-based insights into mental health, capacity, and the psychological impact of workplace environments or incidents.

Family Law Witness Assessments

My family law assessments focus on parenting capacity, attachment, trauma, domestic abuse, and a child’s emotional and psychological needs. I offer balanced, impartial evaluations to assist courts and legal teams in making informed decisions that prioritise the welfare and wellbeing of children and families.

Civil Psychological Injury Claims

I conduct specialist assessments for civil psychological injury claims, including evaluations of trauma, PTSD, workplace-related psychological injuries, and other distressing experiences. My reports provide objective, clinically grounded opinions to support fair outcomes within insurance, occupational, and civil litigation contexts.

Clear, Structured, and Reliable Assessment Process

Every assessment follows a transparent and robust process to ensure accuracy, fairness, and clarity for all parties involved. This includes a detailed review of referral questions, structured clinical interviews, psychometric testing where appropriate, and a comprehensive analysis of psychological functioning in the context of the legal issues being considered.

All reports are clear, evidence-based, and focused on answering the key legal questions. Strong communication is maintained throughout with solicitors and agencies, with reports containing impartial, well-reasoned conclusions that support informed decision-making.
