Capacity To Enter Into A Cohabitation Agreement 

A capacity to enter into a cohabitation agreement assessment determines whether someone has the mental ability to understand & make informed decisions about living together under a shared arrangement. In line with the Mental Capacity Act 2005, the assessment explores whether a person can comprehend the legal, financial, and emotional implications of cohabiting and sharing responsibilities with another individual. OFH Care provides professional, court-compliant cohabitation capacity assessments across England and Wales, helping solicitors, families, and individuals ensure that cohabitation agreements are voluntary and legally secure. 

What is Capacity to Enter into a Cohabitation Agreement? 

The capacity to enter into a cohabitation agreement refers to a person’s ability to understand, retain, and weigh up information about living together and the implications of a cohabitation capacity assessment. A cohabitation agreement (sometimes called a ‘living together agreement’) outlines how property, finances, and shared responsibilities are managed between partners who are not married or in a civil partnership. 

Under the Mental Capacity Act 2005, capacity must be presumed unless there is evidence to suggest otherwise. To have the capacity to enter into a cohabitation agreement, a person must be able to: 

This type of contractual assessment ensures that the person understands what cohabitation involves. It can include financial commitments, shared parenting responsibilities and other legal rights around property or tenancy. 

Why Might Someone Need a Cohabitation Capacity Assessment? 

A cohabitation capacity assessment may be requested when there are doubts about a person’s understanding or decision-making ability in relation to living together with a partner or another person. Common situations include: 

Cohabitation assessments safeguard both individuals and professionals by ensuring the agreement is made voluntarily and with full understanding of its consequences. If you’re unsure whether someone fully understands the implications of living together or signing a cohabitation agreement, a professional capacity assessment can provide clarity. 

How Is Capacity to Cohabit Different from Other Relationship-Based Assessments? 

Each relationship-related decision carries a different level of understanding and legal consequence. It’s important to distinguish between them.

Capacity to Enter into a Cohabitation Agreement 

This focuses on understanding shared living, financial arrangements, and responsibilities without the legal status of marriage or civil partnership. It involves recognising that cohabitation may affect day-to-day life but does not automatically create legal rights to property or inheritance. 

Capacity to Marry 

Marriage or civil partnership creates a legal union with formal rights and obligations. A person must understand that marriage affects property, finances, and potentially children, and that it can only be dissolved through divorce or dissolution. 

Capacity to Sign a Prenuptial Agreement 

A prenuptial agreement requires a higher level of understanding, particularly of financial implications and future legal consequences. The person must be able to comprehend how a prenup may affect their rights if the relationship ends. 

Capacity to Enter into a Tenancy Agreement 

A tenancy agreement is narrower in scope, focusing specifically on housing arrangements. Someone may have the capacity to sign a tenancy but not to enter a cohabitation agreement if the latter involves more complex emotional or financial considerations.

By understanding the differences between these unique contract types, solicitors and families can ensure each decision is properly assessed and supported.

Case Study:
Supporting Capacity to Marry After a Brain Injury

Client:

Ms T, age 36, following a traumatic brain injury. 

Context:

Ms T had been in a long-term relationship and wanted to move in with her partner to share living expenses and care responsibilities for their young child. Her solicitor requested a capacity to enter into a cohabitation agreement assessment because of mild cognitive impairment affecting her short-term memory, reasoning, and ability to manage complex information. The solicitor also wanted reassurance that Ms T understood her financial & parental responsibilities before formalising the arrangement. 

What We Did:

An OFH Care assessor met Ms T in her home environment, where she felt comfortable and supported. The assessment explored her understanding of the cohabitation agreement, including how bills, property, & childcare duties would be shared, & what might happen if the relationship ended. The assessor used plain language, written prompts, & visual aids to ensure full understanding and recall. 

Outcome:

The assessment confirmed that Ms T had the mental capacity to enter into a cohabitation agreement. She demonstrated clear insight into her shared responsibilities and financial decisions. The report provided her solicitor and family with confidence that the agreement was voluntary, informed, and legally secure.
