If you're living with your partner but don't have a cohabitation agreement, you might be wondering what would happen to your home, finances and belongings if your relationship broke down.
Would you automatically be entitled to half of everything? Could you claim a share of a property that isn't in your name? And what happens if you agreed something verbally but never put it in writing?
In this article, Family law expert Simon Immins explains your rights if you don't have a cohabitation agreement, what evidence could help protect your interests and what steps you can take if you've already separated.
What happens if you don’t have a cohabitation agreement?
Not having a cohabitation agreement does not necessarily mean you have no protection. However, it can make disputes more complex, expensive and uncertain.
Where there is no written agreement, the outcome will often depend on the available evidence of ownership, contributions and the parties' intentions. Taking legal advice at an early stage can be crucial to understanding and protecting your position.
What is a cohabitation agreement and why does it matter?
A cohabitation agreement is a written agreement for couples who live together but are not married. It sets out how you will manage your property, money and shared expenses, both during your relationship and if you separate.
In England and Wales, living together does not give you the same financial rights as marriage or a civil partnership.
A cohabitation agreement, sometimes called a living together agreement, helps you both understand where you stand and can reduce the risk of disputes in the future.

What can a cohabitation agreement actually cover?
A cohabitation agreement can cover the practical financial arrangements that matter to you, including:
- Who owns your home and what share belongs to each of you.
- How you will split mortgage payments, household bills and other living costs.
- What should happen if one person contributes more towards a property purchase or renovation.
- How you will divide shared savings, investments and belongings.
- Who will be responsible for repaying debts.
- How you will deal with finances if you separate.
It cannot bind a court’s decisions about children or prevent financial claims being made for their benefit. However, it can help record what you have agreed about your property and finances.

If you have no agreement, what does the law assume?
Having no cohabitation agreement does not mean you have no rights if you separate.
However, it often makes disputes more difficult because the court must determine what was intended from the available evidence rather than relying on a clear written document.
Does the law treat everything 50/50 if nothing was written down?
No. Unmarried couples do not automatically have a right to half each other’s assets when they separate.
In reality, ownership will usually depend on property law principles rather than family law concepts of fairness.
If you bought your family home in joint names without specifying your shares, the usual starting point is equal ownership. Evidence of a different shared intention may change that position.
However, if a property is in your partner’s sole name, the starting point is that it belongs to them. You may still be able to claim a beneficial interest in the property. This will often involve showing a common intention that ownership would be shared and that you relied on that intention to your detriment.

What if you had a verbal agreement about ownership or contributions?
A verbal agreement may help support a property claim, but proving what was said can be difficult, particularly if you and your former partner remember things differently.
The court may consider conversations alongside their conduct, financial contributions and other evidence when deciding whether an informal understanding existed about ownership.
Does the length of your relationship make any difference?
Living together for a long time does not by itself automatically give you rights to your partner’s property. Even after twenty years, you do not automatically gain the same financial rights as a married couple simply because of the length of your relationship.
However, a long relationship may generate more evidence of arrangements that you made, the money you contributed and any evidence that you intended to share ownership.
What evidence can replace a formal agreement?
If you do not have a cohabitation agreement, other records may help explain what you and your partner agreed.
Useful evidence can include bank statements, purchase documents, emails, text messages and accounts of relevant conversations. Whilst these do not necessarily offer the same certainty as a properly drafted agreement, the courts will often look at the whole course of dealings between the parties when determining ownership and financial interests.
Can bank statements showing your contributions be used as evidence?
Yes. Bank statements can show what you paid, when you paid it and, sometimes, what the payment was for. Contributions towards a deposit, mortgage or substantial renovation work may be particularly relevant.
These records may support an argument that the parties intended ownership or responsibility to be shared.
What if you have emails or texts discussing ownership intentions?
Emails, text messages and other written communications can be useful evidence.
A message referring to a property as "our house" or discussing percentages of ownership may help establish the parties' intentions at the relevant time.
The weight attached to any communication will depend on the context and the surrounding evidence. Keep full conversations wherever possible, including dates, so the context is clear.
Can witness evidence from friends or family support your claim?
Yes, potentially. Friends, relatives or professional advisers who were aware of discussions about ownership or financial arrangements may be able to give evidence about what was said.
While independent documentary evidence is often given greater weight, witness testimony can still assist in building a picture of what was agreed or understood between the parties.
What can you still do if you're already separated without an agreement?
If you have separated without a cohabitation agreement, you can still take steps to understand your rights and resolve outstanding financial issues.
Start by gathering documents relating to your home, savings, debts and contributions. A solicitor can review these with you, explain your position and help you decide what to do next.
Many disputes are resolved after separation through negotiation, mediation or legal advice that helps identify and clarify each person's rights and interests.
Is it too late to establish your rights once a dispute has started?
No. You may still be able to establish a share in a property or pursue another claim after separation, even if your former partner disagrees.
The evidence will be important, so keep relevant messages, financial records and ownership documents. Getting legal advice early can help preserve evidence and help you understand the strength of your position.
You may still have options, even if nothing was agreed in writing. Our expert team can help you understand your rights and what steps to take next. Get in touch on 01202 499255 to speak to one of our experts.
Can you reach a formal agreement now, even if you didn't make one at the start?
Yes. You and your former partner can make a separation agreement recording how you will deal with your property, debts and other financial matters.
For example, you might agree to sell your home, arrange for one person to buy the other’s share or divide joint savings.
Reaching an agreement can help you move forward more quickly, with less stress and expense than a court dispute.
Is it still worth making an agreement?
Yes. A cohabitation agreement can be useful whether you are about to move in together or have shared a home for years.
It gives you a chance to discuss expectations, protect individual contributions and agree on how you will manage shared commitments. Having those conversations now can help prevent misunderstandings from becoming more difficult disputes later.
What if you're still living together but the relationship is deteriorating?
If you both remain willing to engage constructively, it may still be possible to put a cohabitation agreement in place.
Doing so can clarify ownership arrangements and financial expectations before any dispute escalates. Independent legal advice for each party will often strengthen the agreement and improve its enforceability.
Can a deed of trust be created retrospectively?
In many circumstances, yes. A deed of trust can be used to record the parties' agreed ownership shares and may take account of historic contributions. However, it generally reflects a present agreement and may not resolve disputes about past intentions or ownership if those matters remain contested.
If a property is jointly owned or one of you wishes to formally recognise the other's interest, a deed of trust can be prepared to record your current intentions and specify their respective shares.
While it may not resolve disagreements about the past, it can provide certainty going forward.
How can you protect yourself next time?
The best protection is to discuss financial arrangements openly and record them in writing at an early stage.
A cohabitation agreement, supported where appropriate by a declaration of trust in relation to property ownership, can help ensure that you and your partner understand your rights and obligations from the outset.
