We bought a home but aren’t married – what happens if we split?

Buying a home together is a huge milestone, but if you’re not married (or in a civil partnership), it can come with a big surprise. In the event of separation, the law treats unmarried couples very differently to married couples. For unmarried couples, the focus is far less on what is fair in the circumstances and far more on what can be established from the documents, evidence and each parties’ intentions.  

Property ownership for unmarried couples 

For unmarried couples, there are two aspects of ownership to consider:  

• Legal ownership: The legal owner of a property is the person(s) named on the property’s title register / deed at the Land Registry. 
• Beneficial ownership: The beneficial owner is the person(s) entitled to the economic benefit of the property. This means they are entitled to share in the value in the property (such as the sale proceeds) and any rental income earned from the property.  

The legal and beneficial ownership may be the same, but not always. In determining how a property is owned, it is assumed, in the first instance, that the beneficial ownership matches the legal ownership as per the property’s title register. In certain circumstances, it is possible to argue that a different ownership position exists (as will be explored below), but this can be difficult to do.  

It is, therefore, essential to consider how a property will be owned and who will be registered on the title register / deed. This is very likely to come into play in the event of separation, as how a property is owned often impacts how it is dealt with after a split.  

Joint ownership: overview  

If you and your partner are both on the property’s title register, there will be joint legal ownership. You will then own the beneficial title for the property either as joint tenants or as tenants in common.  

If own the property as joint tenants: 

• both of you will own the whole of the property; you will not each have a quantified share. 
• it will be presumed that you both own the property equally. 
• neither of you will be able to leave a share of the property in your will. On the death of one of you, that person’s interest in the property will automatically pass to the other without any further action. The surviving co-owner then owns all of the property and on their death, it forms part of their estate. This is known as the "right of survivorship". 

If you own the property as tenants in common: 

• each of you will own a specified share in the property; this is often 50/50 but not always. 
• your respective shares should be recorded in the paperwork as part of your property purchase – usually either in the transfer deed or a declaration of trust; your share will then be presumed to be as per this documentation. 
• your share of the property can be passed on to another person, either during your lifetime or under your will. If you do not have a will when you die, your share will pass in accordance with the rules of intestacy. 

Joint ownership: unequal contributions 

This is where things can become more complicated. Many couples contribute unequally either at the outset, or during the course, of owning a property. This may involve one person providing a larger deposit, contributing more towards the cost of renovations, or paying more of the mortgage.  

Ideally, any unequal contributions should be discussed at the outset when buying a property. If appropriate, these can then be reflected in the ownership shares. If the situation changes, you can complete paperwork during the course of your ownership to formally alter the ownership shares.   

Sometimes, however, this does not happen, and unequal contributions are not properly recorded and reflected in the property ownership. In this scenario, it is possible to argue that your share in the property should be different based on any unequal contributions that have been made. Yet, this can be difficult to do and will depend on the facts of the case. It is not just about who paid what, but also often about what both parties intended those payments to mean.  

Outcomes can vary depending on: 

• how you arranged finances (joint account vs separate payments)
• any conversations, messages or emails about what as ‘agreed’
• what each of you contributed and when 

What if the home is in one person’s name? 

This is where disputes most commonly arise. If only one person is on the title register, the starting point is that they are the legal and beneficial owner of the property. This is the case unless the non-owner can show they have a beneficial interest in the home.  

If you are not on the title, you may therefore find yourself needing to prove you have a share in the property. Again, this can be difficult and will depend on the facts. This could involve arguing, for example, that: 

• there was a shared intention you would both have a stake; and 
• you acted on that intention to your detriment, for instance, by contributing to the purchase price, mortgage, or major improvements.  

To argue this, you would need to provide evidence of your claims. This could include copies of text messages / emails showing what you had agreed and intended between you, as well as evidence of the contributions made. Contributions to general household bills or day-to-day living costs are less straightforward to rely on than direct payments connected to buying, owning, or improving the property. 

Does having children change the position? 

This is one of the biggest surprises for many couples. Having children does not automatically change who owns the property. Ownership is still usually decided by the legal and beneficial position as already explored. 

That said, if you have children, there may be separate legal routes that focus on ensuring a child is housed and supported financially. These claims are different from — and do not necessarily resolve — the question of who owns the home. 

Hence, having children can affect what arrangements might be ordered for housing and support, but they do not automatically rewrite the ownership shares. 

Common misconceptions 

“We have lived together for years — that is basically the same as being married.” 

This is the “common law marriage” myth. Common law marriage does not currently exist as a legal concept in England and Wales. This means that living together does not automatically give you the same rights as married couples. 

“If we split up, the court will just divide everything fairly.” 

When married couples divorce, the court has wide powers to redistribute assets, including property, between the parties to achieve fairness. This is not the case with unmarried couples. Rather, disputes concerning property are usually decided based on who owns what and what you can prove about your intentions and contributions. 

“If I paid more, I’ll definitely get more back.”

Not necessarily. This may be the case if the unequal contribution has been factored into the ownership shares and is reflected in the documentation. If not, you would need to argue your case to show why the ownership position should be altered and you should get more, with evidence in support. This can be tricky and costly to do, and there is no guarantee of success.  

How can unmarried couples can protect themselves? 

Without clear paperwork, disputes concerning property ownership can be stressful, expensive, and highly fact specific. However, there are various practical steps you can take to try to avoid this scenario:  

1. Start your discussions early  

The best time to deal with the matter of ownership is when you are still getting on — ideally before you buy, or at least before circumstances change. It is much easier (and far less expensive) to agree what you both intend while you are aligned, rather than trying to reconstruct conversations and assumptions after a separation. 

Early discussions are particularly important where contributions are unequal. It is sensible to talk through what that money is meant to represent: is it a gift to the relationship, a loan, or should it translate into a bigger share of the equity?  

Such conversations do not need to be uncomfortable. They can be practical and forward-looking, covering questions like: 

• How will the deposit be treated? If it is unequal, do you want that protected? 
• How will ongoing costs (such as the mortgage, bills, insurance, or repairs) be shared?  
• What happens if one person pays for improvements? Do you both benefit equally, or do contributions affect shares?

2. Record your agreement and ownership clearly 

Putting your agreement in writing and documenting the property ownership helps to ensure that, if the unexpected happens, the position is clear and you are not left arguing about what was “understood”. This can be done via the transfer documentation, a declaration of trust or a cohabitation agreement (covered below).  

For example, a declaration of trust can set out: 

• who owns what percentage of the property  
• what happens to the deposit 
• how mortgage payments are treated 
• how renovation costs affect shares (if at all) 

You can record your agreement / the ownership position both at the outset and later on if things change. It can be important to revisit the paperwork if you: 

• have a child 
• receive an inheritance 
• one of you moves out 
• you refinance 
• one person starts paying substantially more than the other  

3. Consider a cohabitation agreement 

A cohabitation agreement is a practical way for unmarried couples to set out what they have agreed in a clear, written document. It can sit alongside other ownership documentation and can cover both the property and wider financial arrangements, for example: 

• who pays what bills 
• what happens if one partner moves out 
• how you would handle a sale, buy-out, or refinancing 

 4. Make (or update) your Wills 

This is particularly important if you own your home as tenants in common. Having a will allows you to confirm who you would like to inherit your share of the property.  

5. Keep a clear financial trail 

This does not mean being transactional or keeping “score”. It simply means making sure there is a clear, accessible record of the key payments and decisions connected to the property — particularly because, for unmarried couples, disputes often turn on ownership and evidence. This can be as simple as keeping:  

• evidence of deposits and transfers 
• records of who paid for major works 
• records of any written discussions about ownership and intentions 

Final thoughts 

No one buys a home expecting to separate — but planning for the “what if” can be one of the most caring and pragmatic things you can do as a couple. A clear agreement reduces uncertainty and protects both of you if life takes an unexpected turn. 

If you are unsure how your property is owned, or you would like to consider putting sensible protections in place, it is worth getting early advice, particularly before you buy, refinance, or spend significant sums.
