What Is a Capacity to Enter Contracts Assessment?

A Capacity to Enter Contracts assessment is a clinical evaluation of an individual’s ability to participate in contractual agreements. It focuses on whether a person was suffering from a clinically recognised impairment at the time the contract was formed and how that impairment affected their functional capacity.

The legal test originates in common law (including Imperial Loan Co v Stone [1892]) and may be considered alongside the principles of the Mental Capacity Act 2005 where relevant. It requires the person to understand the nature of the transaction when it is explained to them, including the duties and risks involved in the specific contract in question.

  • Understanding information — ability to comprehend the terms and the nature of the transaction
  • Retaining information — the capacity to hold the details long enough to make a choice
  • Weighing risks — evaluating the benefits and potential liabilities of the agreement
  • Communication — expressing a clear and consistent decision regarding the contract
  • Specific complexity — capacity relative to the sophistication of the particular agreement
  • Temporal relevance — clinical evidence of capacity at the exact moment of execution

Our expert witnesses provide reports compliant with CPR Part 35 (where applicable) to assist the court in determining whether a contract may be voidable. These assessments require a nuanced understanding of how clinical symptoms intersect with legal thresholds.

The resulting opinion provides objective evidence regarding the presence of an impairment and its causal link to the decision-making process, assisting the court in reaching its determination.

Key Assessment Components

Our assessment evaluates the following areas:

Clinical Interview

A face-to-face or remote session to assess mental state and cognitive function.

Documentation Review

Thorough analysis of medical records and contemporary evidence surrounding the contract.

Cognitive Screening

Formal testing to identify impairments in reasoning, memory, or executive function.

Third-Party Evidence

Incorporation of collateral information from witnesses or family members where appropriate.

Functional Assessment

A specific review of the individual’s ability to process complex data related to the agreement.

Legal Nexus

A clear explanation of how clinical findings relate to statutory tests for capacity.
