How to Resolve Joint Property Ownership Disputes

Property ownership disputes can arise when relationships break down or circumstances change. When two people own a property together, disagreements can quickly become difficult if one person refuses to sell or contribute to the costs.

If the dispute is not resolved, it can leave your money tied up in the property, increase legal costs and cause you emotional stress.

In this article, we explain your rights under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA). We will also explain the steps you can take to protect your financial interests, access your share of the property’s value and work towards a fair, legally binding resolution.

What are joint property ownership disputes, and why do they happen?

Property conflicts can arise for many reasons, most commonly when romantic relationships break down, but it can also happen between family members, friends, and business partners.

Unmarried couples separating and the 'common law marriage' myth

Separating, divorcing, or breaking up with your partner is one of the most common causes of property disputes. Compared to married couples, unmarried cohabitants can be more vulnerable because of the widespread misconception that ‘common law marriage’ gives them the same legal rights as married couples.

In England and Wales, ‘common law marriage’ is just a myth. This means that, unlike married couples going through a divorce, unmarried couples do not automatically have access to the family court’s powers to divide their assets.

An unmarried partner or family member who is not named on the title deeds may need to prove that they have a beneficial interest in the property. This can be done by establishing a Constructive Trust, where there was a shared understanding or promise that they would have a share of the property. They may also be able to establish a Resulting Trust by showing that they made a direct financial contribution towards the purchase price.

Disagreements over deposits, mortgages and renovation costs

Disputes can also arise when co-owners contribute different amounts of money towards a property. Common areas of disagreement include unequal deposits, one owner paying more of the monthly mortgage, or one person paying for major renovations themselves.

These disputes can become more difficult when there is no legal agreement setting out how these extra contributions will be recognised or repaid.

Family members, friends, and multi-generation co-ownership

When parents or other relatives help fund a deposit or purchase a property together with younger family members or friends, disagreements can easily happen if personal or financial circumstances change. If you want to avoid things escalating, you should draft a written agreement that specifies who owns what from day one.

Buy-to-let and commercial investment property deadlocks

Co-investors in rental or business properties frequently clash over exit strategies, rental income distribution, or a stubborn refusal from one party to liquidate underperforming assets when market conditions shift.

How UK law and TOLATA 1996 can resolve disagreements

When co-owners cannot agree, it is important to understand the law and your legal rights before deciding what to do next.

How to deal with a complex case

• Equitable accounting: When a court orders a property to be sold or one co-owner to buy out the other under TOLATA, it can adjust final payouts to account for what each person has contributed.
• Occupational rent: If one co-owner stays in the property alone, they may have to pay the other co-owner occupational rent.
• Mortgage payments: The court may take account of mortgage payments made post-separation. Capital payments directly increase equity and may be credited back to the payer, whereas interest payments are often treated differently depending on who occupied the home.
• Major improvements: Big changes to the property that can boost its value, like a loft conversion, can be factored into the final settlement, unlike standard repairs and maintenance.
• Interim orders and vacant possession: The court can direct a co-owner to vacate by a specific date to allow proper marketing and viewings.
• Creditors and bankruptcy: If a co-owner becomes bankrupt or a creditor holds a charge over their share, the court must weigh the creditor's legal interests during sale proceedings.
• No written Deed of Trust: In the absence of a written trust, people may rely on proprietary estoppel if they acted on a promise to their financial detriment.

How to solve a co-ownership dispute

Resolving a property dispute usually requires following four steps:

Get an independent valuation from a RICS-registered surveyor to establish the property’s current market value. If you want to buy your co-owner’s share, speak to your mortgage lender to check how much you could borrow and whether you are likely to be approved.

If you own the property as Joint Tenants, you can formally end the joint tenancy by serving a Notice of Severance under Section 36(2) of the Law of Property Act 1925. This Severance of Joint Tenancy should be served correctly under Section 196, and a Form A Restriction (Form RX1) should be registered at HM Land Registry to protect your estate.

By severing the joint tenancy, you will each own an equal share as Tenants in Common, unless your shares have been changed by an agreement or other legal claim. If you believe you are entitled to unequal shares, such as 70/30, you may need to rely on a Constructive Trust, proprietary estoppel or equitable accounting.

Before starting court proceedings, you should follow the relevant pre-action requirements by sending a formal Letter Before Action. This sets out your claim and gives the other party an opportunity to respond and seek an agreement before court proceedings begin.

Mediation or negotiations through a property dispute solicitor can help you reach an agreement without the cost and stress of a court case. If you reach an agreement after court proceedings have started, it can be recorded in a binding Tomlin Order. If you settle before starting court proceedings, you can use a Property Settlement Agreement or Deed of Settlement.

A Tomlin Order can keep the agreed terms confidential and allows them to be enforced through court. Depending on your circumstances, you can also consider other options to force a sale by completing a Transfer of Equity using a TR1 Form. If an uncooperative owner refuses to sign the TR1, a judge can sign it on their behalf under Section 39 of the Senior Courts Act 1981, or via a Vesting Order.

Joint property ownership disputes typically arise when relationships break down or investment partners disagree on the future of an asset. The two most common catalysts for conflict are when one party wishes to extract their financial contribution from the property, or when one party wishes to force a sale against the other's wishes.

How these disputes are resolved depends entirely on your legal relationship to the co-owner, your initial purchasing intentions, and how the property is registered with HM Land Registry.

The root causes of joint property disputes

Property conflicts rarely resolve themselves. They usually require formal legal intervention, especially when there is no pre-agreed exit strategy, as is normally included in a Deed of Trust. Common dispute triggers include:

• One owner wants to sell the property while the other refuses to leave.
• Disagreements over the division of sale proceeds.
• Disputes over unequal financial contributions to the mortgage or property maintenance.

Key UK laws regarding joint ownership of property

Property disputes are governed by a strict framework of UK legislation. Understanding which laws apply to your specific situation is the first step in resolving the conflict.

Different joint ownership disputes

Here are a number of scenarios to help you see if it aligns with your situation.

Scenario 1: Unmarried joint tenants

If you are unmarried and registered as Joint Tenants, a dispute can be complex because neither party owns a quantifiable, separate share to sell. To protect your interests, you must first sever the joint tenancy by serving a written Notice of Severance.

Severing the tenancy changes your legal status to Tenants in Common. However, it is vital to mutually agree on the division of your beneficial interests and secure this within a formal Property Settlement Agreement to prevent drawn-out legal battles. If you fail to agree on the split and simply serve a Notice of Severance, you risk facing a lengthy and costly legal dispute where each party must present evidence of their financial contributions to the courts.

Scenario 2: Unmarried Tenants in Common
(With and without a Deed of Trust)

If you are Tenants in Common, your respective shares should be documented on the TR1 form filed with HM Land Registry at the time of purchase. While the TR1 is often supported by a separate Deed of Trust, this isn't always the case.

• Without a Deed of Trust: Your share is dictated by what is stated on the TR1 form. If the 'equal shares' box was ticked, or if no specific percentage was documented, the courts operate on the legal presumption of a 50:50 split. To claim otherwise, the burden of proof falls entirely on you to produce hard evidence demonstrating that a different financial split was intended.
• With a Deed of Trust: Disputes are drastically reduced if a Deed of Trust or Cohabitation Agreement is in place. This legally binding document pre-agrees how the beneficial interest is divided and establishes a clear framework for how the property can be sold or bought out in the future. As an 'express declaration of trust', it is treated by the courts as conclusive. It is extremely difficult to challenge unless a party can explicitly prove fraud, undue influence, a mistake at the time of drafting, or that a subsequent legal agreement superseded it.

Scenario 3: Resolving disputes for married couples

If you are married, property disputes fall under family law and the Matrimonial Causes Act 1973, making the process inherently different. Regardless of what a deed says or whose name is on the legal title, the family courts will decide how the marital assets will be shared.

• Post-marital assets: Whether you are Joint Tenants or Tenants in Common, a property bought during the marriage is considered a matrimonial asset. You cannot simply force a quick sale or extract your share independently; the property must be dealt with as part of the formal divorce settlement, which usually begins with a presumption of a 50:50 split.
• Pre-marital assets: If one person owned the property before the marriage, it is generally considered a non-matrimonial asset. While it may still be factored into a financial settlement (especially if the other spouse contributed to the mortgage or if it became the primary family home), it frequently remains with the original owner.

I own 50% of a property. What are my rights?

If you are a legally recognised 50% beneficial owner, you have distinct rights under UK law. These include:

• The right to reside in the property.
• The right to 50% of the proceeds upon a sale.
• The right to 50% of any rental income generated by the property. Legally, your default entitlement to rental income directly mirrors your share of the beneficial interest.
• The right to sell the property, provided it is a joint decision or mandated by a court order.

It is this final point that often triggers a dispute. You cannot sell a jointly owned property unless all legal owners agree. Even if one party attempts to market the property, the sale cannot be legally completed because the non-consenting party can simply refuse to sign the protocol forms, the contract, and the TR1 transfer deed. In this stalemate, you are stuck unless you apply to the court to force a sale.

Using TOLATA to force a property sale

When one co-owner refuses to sell, the other can make formal legal enquiries under the Trusts of Land and Appointment of Trustees Act 1996 (TOLATA). A TOLATA claim allows you to apply to the County Court for an Order for Sale.

When reviewing a TOLATA claim, the court relies strictly on factual evidence, not emotional arguments. Under Section 15 of the Act, the judge must consider the original intentions of the buyers, the welfare of any minors living in the property, and the interests of any secured creditors (such as mortgage lenders) before making a decision. The courts do not automatically grant an order for sale; there are several potential outcomes. Read more about the different Court Orders for forced sales.

How to finalise your settlement

Once you have agreed on how the property proceeds will be divided, the biggest mistake you can make is to simply complete the sale or transfer of equity without formalising the agreement. Without a binding legal document, you risk your ex-partner or co-owner pursuing a further financial claim against you in the future (taking a 'second bite of the cherry'). And yes, this happens frequently!

To completely eliminate this risk, both parties must sign a mutually agreed Property Settlement Agreement. This is a robust legal document drafted by a solicitor and executed as a deed (meaning it must be formally witnessed). However, to ensure this agreement is entirely watertight and cannot be contested later under claims of duress or misunderstanding, both parties should obtain Independent Legal Advice (ILA) before signing. When a settlement deed is backed by ILA, it establishes a definitive 'clean break' for unmarried couples, leaving virtually zero scope for a court to overturn it later.
