Capacity To Enter Into A Sexual Relationship 

A capacity to enter into a sexual relationship assessment determines whether a person has the ability to understand and consent to sexual activity. Conducted under the Mental Capacity Act 2005, this assessment explores whether the person comprehends the nature of intimacy, mutual consent, and potential consequences such as pregnancy, sexually transmitted infections (STIs), and emotional impact. OFH Care provides professional, court-compliant assessments across England and Wales, helping individuals, families, and solicitors balance autonomy with safeguarding.

What is Capacity to Enter into a Sexual Relationship? 

Capacity to enter into a sexual relationship, also called capacity to consent to sex, refers to an individual’s ability to understand what sexual activity means and to decide freely whether to engage in it.

Under the Mental Capacity Act 2005, a person must be presumed to have capacity unless proven otherwise. Case law, including IM v LM (2014) and A Local Authority v JB (2021), guides professionals in determining this form of capacity.

This assessment is decision-specific and time-specific. A person may have the capacity to form romantic relationships or to marry, but not necessarily the capacity to consent to sexual activity at a given time or in a particular situation.

A capacity to consent to sex assessment is often requested when there are concerns about a person’s ability to make safe, informed decisions about sexual relationships or intimacy. Common reasons include:

At OFH Care, we believe that every individual has the right to explore relationships, intimacy, and connection. Our assessments ensure this is done safely, ethically, and with dignity and help to balance protection with personal freedom.

Understanding Capacity, Consent, and Safeguarding 

People with cognitive or behavioural changes, especially after a traumatic or acquired brain injury, may still wish to date, form romantic bonds, or express sexual desires. However, such situations can create complex safeguarding challenges. 

A capacity to consent assessment helps to ensure that:
Safeguarding aims to protect vulnerable individuals from harm while preserving their autonomy, i.e., the right to make their own informed decisions. At OFH Care, our approach respects personal rights while prioritising safety and wellbeing.

Case Study:
Supporting Safe Relationships After Brain Injury

Client:

Mr R, age 32, following a traumatic brain injury

Context:

After brain injury rehabilitation, Mr R began a new romantic relationship. His support team noticed impulsive behaviour and occasional disregard for personal boundaries, raising concerns about his understanding of consent and sexual risk. His case manager referred him to OFH Care for an assessment of capacity to enter into a sexual relationship.

What We Did:

An experienced mental capacity assessor from OFH Care met Mr R in his home to discuss topics such as mutual consent, contraception, and the risk of sexually transmitted infections. The assessor used diagrams and simplified language to support comprehension of key concepts. Mr R demonstrated an understanding of mutual consent, the right to say no, and the importance of using protection to prevent STIs. 

Outcome:

The assessment concluded that Mr R had capacity to consent to a sexual relationship. The report provided a clear professional opinion, offering reassurance to his support team that Mr R’s autonomy could be respected while ensuring his safety was appropriately monitored.
