Buying a home together with unequal deposits
31 July 2026
Taylor Bracewell
When unmarried couples purchase property together but contribute different amounts towards the deposit, problems can arise if the relationship later breaks down. Many people assume their financial input will be automatically recognised and returned to them, but the reality is often more complex. Without clear documentation beforehand, the outcome may differ significantly from what either party expected.
Why unequal deposits can lead to disputes
At the outset of a relationship, property purchases are often made on trust, with limited discussion about what would happen if things go wrong. Informal arrangements are common, and contributions or intentions are frequently not recorded in writing.
Issues typically only surface on separation, when each party has a different understanding of what was agreed. One person may expect to recover their larger contribution, while the other may believe that joint ownership means everything should be shared equally.
How ownership is determined for unmarried couples
Unmarried couples do not benefit from the same legal framework as married couples upon divorce. The courts do not strive for fairness for cohabitees, and they do not have the broad discretion to achieve this. Instead, when disputes arise the court applies the property and trust law principles which are generally more rigid and evidence based.
Two key concepts apply:
- Legal ownership – refers to whose names are on the title deeds of the property. This shows who owns the property in law and who has authority over it on paper.
- Beneficial ownership – refers to who actually owns the value of the property (equity) and in what proportions. This determines how sale proceeds are divided if the property is sold.
Where a property is held jointly, there is often a starting assumption of equal ownership. However, this can be displaced if there is clear evidence that the parties intended something different. Without that evidence, the registered legal position carries significant weight.
What will the court consider?
If a dispute arises, the court will look at the parties’ intentions at the time of purchase and how they behaved during ownership. Relevant factors may include:
- The source and proportions of the deposit paid
- Any written agreements, such as a declaration of trust or cohabitation agreement
- Correspondence (emails, texts, solicitor letters) showing discussions about ownership and financial intentions
Common Misunderstandings
“My deposit will automatically be returned to me.”
This is not guaranteed. Unless there is a clear written agreement, the law may not recognise an entitlement to repayment. Even where an agreement exists, it should be explicit about whether it covers only the original contribution or also any increase in property value.
“Living together gives us legal protection.”
Unmarried cohabitants do not have the same rights as spouses or civil partners. The current position in the law requires a cohabitant to prove their interest in the property through contributions and maintenance. Child-related financial support is a sperate issue, it may be addressed in different ways including the Child Maintenance Service or Schedule 1 Children Act 1989 applications.
“We had an informal agreement, so that should be enough.”
Verbal arrangements are often difficult to prove and can be disputed or misunderstood. Without written terms, courts must reconstruct intentions, which can lead to uncertainty and expensive litigation.
How to protect yourself
There are practical steps couples can take to reduce risk and avoid disputes:
Agree ownership at the outset – Have clear discussions about how deposits, mortgage payments, and ongoing contributions will affect ownership shares.
Put arrangements in writing – A declaration of trust can record how the property is owned and in what proportions. A cohabitation agreement can also set out expectations about ownership, contributions, and what should happen if the relationship ends.
Keep arrangements under review – If circumstances change, agreements should be revisited and updated to reflect current intentions and financial contributions.
How can Taylor Bracewell’s Family team help?
Buying a property together with unequal deposits does not have to result in uncertainty, but it does require careful planning. Clear documentation and early legal advice can prevent misunderstandings and significantly reduce the risk of dispute.
Taking steps at the outset is not pessimistic, it is practical risk management that protects both parties and provides certainty if the relationship changes.
