As more couples choose to live together without marrying or entering into a civil partnership, it’s increasingly important to understand the legal position of cohabiting partners. A widespread misconception—often referred to as the “common law marriage myth”—is that couples who live together for a certain period automatically acquire the same legal rights as married couples. Unfortunately, this is not the case.
A cohabitation agreement is a practical and proactive way for couples to protect themselves and clarify arrangements while living together. In this blog, we explore what these agreements are, what they can include, and why they can be so beneficial.
What is a cohabitation agreement?
A cohabitation agreement is a legally binding document entered into by a couple who live together (or are planning to). It sets out how finances, property, and other matters will be dealt with during the relationship and in the event that the relationship comes to an end.
While discussing the possibility of separation is not always easy, having a clear agreement in place can help avoid uncertainty, disputes, and costly legal proceedings in the future.
What can a cohabitation agreement include?
Cohabitation agreements are flexible and can be tailored to suit your particular circumstances. Common provisions include:
1. Property ownership
- Who owns the property you live in (whether jointly or in one person’s name)
- How mortgage payments will be made
- What should happen to the property if you separate (e.g. sale, buy-out arrangements)
2. Financial contributions
- Contributions to rent or mortgage payments
- How household bills and living expenses are shared
- Responsibility for joint and individual debts
3. Savings and assets
- Ownership of savings accounts and investments
- How jointly owned assets (such as cars or furniture) are divided if the relationship ends
4. Business interests
For individuals who own or have an interest in a business, a cohabitation agreement can be particularly important. It can address:
- Whether a business is owned solely by one party or jointly
- How the value of the business will be treated if the relationship ends
- Protection of the business from potential claims by the other partner
- Whether one partner has contributed financially or otherwise (e.g. unpaid work) to the business
- Arrangements for any income derived from the business
This can be crucial in preventing disputes, particularly where a business has grown during the relationship or where one partner has supported the other in developing it.
5. Bank accounts
- Whether finances will be kept separate or pooled
- Arrangements for joint accounts
6. Children (where applicable)
While a cohabitation agreement cannot definitively determine arrangements for children (as the court will always prioritise the child’s best interests), it can record intentions regarding:
- Day-to-day care
- Financial contributions towards children
7. Separation arrangements
- How finances and property will be divided
- Whether one party will provide financial support to the other
- Process for resolving disputes
8. Household contents
- Who owns specific items
- How items will be divided if you separate
Why are cohabitation agreements important?
1. Lack of legal protection for cohabiting couples
Unlike married couples, cohabiting partners do not automatically have rights to each other’s property or finances if they separate. This can lead to significant financial vulnerability, particularly if one partner has made indirect contributions (such as caring for children or supporting the household).
A cohabitation agreement helps bridge this legal gap.
2. Clarity and transparency
By setting expectations from the outset, both parties have a clear understanding of their financial and legal position. This can strengthen the relationship by reducing uncertainty and potential misunderstandings.
3. Preventing disputes
Separation can be emotionally challenging. Having an agreement already in place reduces the likelihood of disagreements, as the key issues—including property, finances, and even business interests—have already been addressed.
4. Cost-effective
Resolving disputes through the courts can be expensive and time-consuming. A cohabitation agreement is a relatively low-cost way of protecting your interests and avoiding litigation later on.
5. Tailored to your needs
Every relationship is different. A cohabitation agreement can be bespoke, reflecting your personal circumstances, financial arrangements, business interests, and intentions.
6. Protection for significant contributions
If one partner is contributing more financially (e.g. deposit for a property), supporting a partner’s business, or sacrificing career opportunities (e.g. for childcare), the agreement can record and protect this.
Is a cohabitation agreement legally enforceable?
In England and Wales, cohabitation agreements are generally enforceable, provided that:
- Both parties enter into the agreement freely
- There is full financial disclosure
- Each party has had the opportunity to seek independent legal advice
- The terms are fair and reasonable
A properly drafted agreement by a family law solicitor significantly increases the likelihood that it will be upheld if challenged.
When should you enter into a cohabitation agreement?
It is sensible to consider a cohabitation agreement:
- Before moving in together
- When purchasing a property jointly
- When one party owns a business or has significant assets
- When one party is making a larger financial contribution
- When there are children from a previous relationship
- When financial or business circumstances change
Final thoughts
While it may feel unromantic to plan for the possibility of a relationship breaking down, a cohabitation agreement is ultimately about protecting both parties and providing peace of mind.
Taking the time to put clear arrangements in place can help ensure fairness, safeguard assets including business interests, and avoid disputes in the future.
