These assessments are frequently required in contentious probate or financial litigation where there are allegations of coercive behaviour or the exploitation of a vulnerable adult.
What Is an Undue Influence Assessment?
An assessment of undue influence examines the psychiatric and psychological factors that may lead an individual to be susceptible to the control or manipulation of another party. In legal proceedings, the expert is asked to provide an opinion on whether a person’s autonomous decision-making may have been compromised, such that their independent decision-making may have been significantly impaired.
The evaluation focuses on the presence of vulnerability and the dynamics of the relationship in question. Unlike a standard capacity test, this assessment looks specifically at the interpersonal pressure and whether the individual was in a state where they could no longer exercise independent judgment.
- Vulnerability factors — Analysis of cognitive impairment, physical frailty, or emotional dependency
- Relationship dynamics — Evaluating levels of trust, isolation, and dominance within the dyad
- Psychological pressure — Evidence of persistent nagging, threats, or emotional exploitation
- Free will — Determining if the transaction aligns with the individual’s long-term wishes and values
- Cognitive capacity — Assessing the mental ability to understand and resist external influence
- Independent advice — Considering whether the individual was prevented from seeking objective guidance
The assessment is conducted by a specialist expert witness who integrates clinical findings with the legal principles of the Mental Capacity Act 2005. The clinician provides a detailed opinion on whether the individual’s mental state rendered them unusually susceptible to the influence of others.
This process often involves a retrospective analysis, particularly in probate cases. The expert synthesises medical records and witness testimony to reconstruct the individual’s psychological profile at the time the disputed document was executed.
