What Is a Capacity for Sexual Relations Assessment?
A Capacity for Sexual Relations assessment evaluates whether an individual possesses the requisite mental capacity to consent to sexual activity. This is an act-specific rather than person-specific assessment, focused on whether the person understands the nature of the act and the risks involved.
The legal framework is governed by the Mental Capacity Act 2005, with critical guidance from recent case law such as A Local Authority v JB [2021]. Experts must determine whether the individual can understand, retain, use or weigh relevant information regarding the mechanics of the act, health risks, and the fundamental requirement of reciprocal consent.
- The mechanics — understanding what the physical act of sexual intercourse involves
- Health risks — awareness of the risk of sexually transmitted infections and pregnancy
- The right to withdraw — understanding that consent can be withdrawn at any time
- Mutual consent — the requirement that the other person must also agree to the act
- Specific consequences — understanding the potential physical and social results of the activity
- Voluntariness — the ability to make a choice without undue influence or coercion
Expert witnesses provide reports compliant with CPR Part 35 (where applicable) that assists the court in determining if a functional impairment prevents an individual from making a capacitous decision. This involves a rigorous clinical interview, review of psychiatric history, and an analysis of the person’s decision-making process.
The assessment must be conducted with sensitivity to the individual’s Human Rights, specifically the right to a private and family life under Article 8. Our experts provide clear, evidence-based opinions on whether the person lacks capacity and identify any practicable steps that could support their autonomy.
