What Is a Single Expert Report in Family Law? A Plain-Language Guide for Australian Families
Navigating family law proceedings can feel overwhelming, particularly when decisions involve children, parenting arrangements, or complex family dynamics. In some cases, the Court may require an independent psychological assessment to help inform these decisions.
This is where a single expert report psychologist becomes involved.
In this guide, we explain what a Single Expert Report is, how it is used in the family court, and what families can expect from the process.
What Is a Single Expert Report?
A Single Expert Report is a formal psychological assessment prepared for the Court by an independent clinician. The purpose of the report is to assist the Court in making decisions that are in the best interests of the child.
In family law matters, a single expert witness in family court is jointly appointed by both parties or ordered by the Court. This means:
The psychologist is impartial and independent
They do not act for either parent
Their role is to provide an objective, evidence-based opinion
These reports are commonly referred to as family law reports or family reports.
Why Are Family Law Reports Used?
Family law proceedings often involve complex emotional and family dynamics that are not always visible through court documents alone.
Family law reports help the Court to better understand:
The child’s needs and wellbeing
The nature of each parent-child relationship
Family dynamics and communication patterns
Any psychological or developmental considerations
Risk factors, where relevant
The goal is not to determine “who is right”, but to provide a balanced, clinically informed perspective that supports decision-making in the child’s best interests.
What Does a Single Expert Witness in Family Court Do?
A single expert witness in family court conducts a comprehensive assessment of the family. This typically involves:
Reviewing relevant documents (e.g. affidavits, previous reports)
Interviewing parents and, where appropriate, children
Observing interactions between parents and children
Considering developmental, emotional, and relational factors
Following this process, the psychologist prepares a structured report that is submitted to the Court.
What Is Included in a Single Expert Report?
A Single Expert Report usually includes:
Background information about the family
A summary of interviews and observations
Clinical impressions based on the assessment
Consideration of the child’s needs and circumstances
Recommendations regarding parenting arrangements
These recommendations are not decisions themselves, but are one of several factors the Court considers when making its decision.
What Should Families Expect During the Process?
For many families, participating in a family report can feel unfamiliar or even confronting. Understanding the process can help reduce uncertainty.
You can expect:
A structured and professional assessment process
Questions about your parenting, relationships, and family history
A focus on the child’s wellbeing rather than individual grievances
A neutral and non-judgemental approach
It is important to approach the process openly and honestly, as the aim is to gain an accurate understanding of the family situation.
How Is a Single Expert Report Used by the Court?
The Court uses the report as one piece of evidence when making decisions about parenting arrangements and other family law matters.
While the report does not determine the outcome, it often plays an important role in:
Clarifying complex family dynamics
Highlighting the needs of the child
Informing judicial decision-making
Because the psychologist is appointed as a single expert witness in family court, their independence is central to the value of the report.
The Role of Psychologists in Family Law Reports
Psychologists involved in preparing family law reports bring clinical training and experience in understanding behaviour, relationships, and emotional development.
Within their clinical niches, psychologists may have experience working with:
Family dynamics and parenting
Child development and attachment
Emotional regulation and mental health
High-conflict family situations
Their role is not to advocate for either party, but to provide an objective, clinically informed perspective.
