Property Co-Ownership Disputes Lawyers Brisbane
Shared ownership is straightforward until it is not. When co-owners cannot agree, the law provides a way through.
Co-ownership disputes arise between former partners, siblings inheriting property, investors who have fallen out, and business associates whose arrangements were never properly documented. The property may be the co-owners’ most significant asset. That makes the dispute consequential and, often, deeply personal.
What many co-owners do not know is that the law provides powerful remedies, including the ability to force a sale over the objection of a co-owner who refuses to engage. No co-owner can be held captive in a property relationship indefinitely.

How Co-Ownership Works Under Queensland Law
Joint Tenancy and Tenants in Common
Property in Queensland can be held by co-owners in two ways, and the distinction matters for how a dispute is resolved.
Under a joint tenancy, co-owners hold the property together without defined shares. When one joint tenant dies, their interest passes automatically to the surviving joint tenant or tenants by right of survivorship. Married and de facto couples commonly hold property as joint tenants.
Under a tenancy in common, each co-owner holds a defined share of the property. Those shares need not be equal. On the death of a co-owner, their share passes under their will or the intestacy rules, not automatically to the survivor. Investment properties are frequently held as tenants in common to allow unequal contributions to be reflected in the title.
The form of co-ownership affects the nature of the dispute, the remedies available, and how proceedings are structured. Severing a joint tenancy (converting it to a tenancy in common) is itself a step that may need to be taken, and taken carefully, before other action proceeds.
Contributions, Equitable Interests and Constructive Trusts
The legal title to a property does not always reflect the full picture of who has contributed to its acquisition, mortgage repayments or improvement. Where one co-owner has contributed more than their legal share reflects, equity may recognise a larger interest through a constructive trust or resulting trust.
These claims are fact-intensive and require careful analysis of financial contributions, agreements made between the parties, and the conduct of the parties over the course of the ownership. They frequently arise in disputes between unmarried couples and in family property arrangements where written agreements were never made.
We advise on equitable claims alongside the statutory remedies available to co-owners, and we build the evidentiary foundation for these arguments from the outset.
Remedies Available to Co-Owners
Queensland law provides a range of remedies for co-owners in dispute. The right remedy depends on the nature of the dispute, the co-ownership structure, and what outcome the client is seeking. In most cases, more than one remedy is available and the strategy involves selecting the combination most likely to produce a result efficiently.
Partition
A court order physically dividing the property between co-owners, giving each separate title to a defined portion. Rarely practical for a single residential lot but available for land that can be subdivided.
Statutory Trustee for Sale
An order appointing a statutory trustee under the Property Law Act 1974 (Qld) to sell the property. The trustee sells and distributes the proceeds. A powerful remedy when one co-owner refuses to cooperate.
Order for Sale
A court order requiring the property to be sold, with proceeds divided in accordance with the co-owners’ respective interests. More direct than a partition where physical division is impractical.
Buyout
One co-owner acquires the other’s interest at a price determined by agreement or, where agreement is not possible, by independent valuation or court determination. Often the preferred outcome where one party wants to retain the property.
Account of Profits and Contribution
Where one co-owner has occupied the property exclusively or collected rent, an accounting may be required to ensure the non-occupying co-owner receives their proper share of the benefit.
Equitable Relief
Injunctions, declarations of trust, and orders recognising constructive or resulting trust interests where the legal title does not reflect the parties’ true beneficial ownership.
The Statutory Trustee for Sale: A Closer Look
The appointment of a statutory trustee for sale under Part 4 of the Property Law Act 1974 (Qld) is one of the most significant remedies available to a co-owner who cannot achieve resolution by agreement. It deserves careful attention.
What It Is
A statutory trustee for sale is an independent person, typically an experienced solicitor or trustee company, appointed by the Supreme Court of Queensland to hold the property on trust for the co-owners and to effect its sale. Once appointed, the statutory trustee has authority to sell the property without the consent of either co-owner. The sale proceeds are then distributed to the co-owners in accordance with their respective interests, after payment of the trustee’s costs and any encumbrances.
When It Is Available
The court has a broad discretion to appoint a statutory trustee for sale. The application is most commonly brought where:
- Co-owners cannot agree on whether to sell, and one party is blocking a sale
- One co-owner refuses to engage in any form of negotiation or alternative dispute resolution
- The property is held as tenants in common and the parties' interests are clearly defined
- A joint tenancy has been severed and the parties cannot agree on the disposition of the property
- The co-ownership has broken down to the point where continued joint ownership is unworkable
The court does not require the applicant to establish wrongdoing or fault. A co-owner who simply refuses to engage can be the subject of an application. The court’s jurisdiction is broad and, in practice, applications for a statutory trustee for sale regularly succeed where the relationship between co-owners has genuinely broken down.
What Happens to Competing Claims
The appointment of a statutory trustee does not finally resolve all disputes between co-owners. Where there are competing claims about the proportions in which the co-owners are entitled to the proceeds, whether one co-owner has a larger equitable interest than the legal title reflects, or whether one party is owed a contribution for mortgage payments, rates or improvements, those questions are determined by the court either at the time of the trustee appointment or separately.
It is critical that these arguments are identified and pleaded correctly from the outset. A co-owner who delays in asserting an equitable interest or contribution claim risks having those arguments disregarded in the distribution of sale proceeds.
The Practical Effect
The appointment of a statutory trustee for sale is a serious step with real consequences. Once the trustee is appointed, neither co-owner can prevent the sale. This makes the application a powerful lever in negotiations: the credible threat of an application, backed by a litigation-ready position, frequently produces a negotiated outcome before an application is ever filed.
A co-owner cannot be held in a property relationship against their will indefinitely. Where negotiation has failed, the court has the power to break the deadlock.
Partition: When Physical Division Is Possible
Partition is the physical division of co-owned land into separate parcels, with each co-owner receiving separate title to their portion. It is the original remedy for co-ownership disputes at common law, and it remains available under the Property Law Act 1974 (Qld).
In practice, partition is only available where the land is physically capable of subdivision. A single residential lot in a suburban street cannot be partitioned. A larger parcel of rural land, a property with separate buildings, or a site with development approval for multiple lots may be suitable candidates.
Where partition is available and practical, it can be the preferred outcome for co-owners who each want to retain a portion of the property without being forced to sell. We assess whether partition is technically available and strategically sensible in the context of your specific property and dispute.
Contributions, Occupation and the Duty to Account
Not every co-ownership dispute is simply about whether to sell. Many disputes involve questions about how the property has been managed during the co-ownership period and what each party is owed.
Mortgage and Outgoing Contributions
Where one co-owner has paid more than their proportionate share of the mortgage, rates, insurance or maintenance costs, they may be entitled to a contribution from the other co-owner. The calculation of contribution claims can be complex, particularly over long periods where payments have been made in varying amounts by different parties.
Exclusive Occupation
At common law, a co-owner who exclusively occupies co-owned property does not automatically owe an occupation rent to the non-occupying co-owner, unless the non-occupying co-owner has been excluded from the property. However, equity may in certain circumstances require an account of occupation rent, particularly where one co-owner has had the full benefit of the property over an extended period.
Rental Income
Where co-owned property has been rented to a third party, each co-owner is entitled to their proportionate share of the net rental income. Disputes arise where one co-owner has managed the property, collected rent and failed to account to the other. We bring accounting claims alongside the primary remedy sought to ensure the client’s full entitlement is captured.

Frequently Asked Questions
Can I force the sale of a jointly owned property if my co-owner refuses to sell?
Yes. Under the Property Law Act 1974 (Qld), a co-owner can apply to the Supreme Court for the appointment of a statutory trustee for sale, or for an order for sale or partition of the property. The court has a broad discretion to make these orders and does not require the applicant to establish fault or wrongdoing on the part of the other co-owner. A co-owner who simply refuses to engage or agree to a sale can be the subject of a successful application. The credible prospect of such an application frequently produces a negotiated outcome before proceedings are filed.
What is a statutory trustee for sale and how does the process work?
A statutory trustee for sale is an independent person appointed by the Supreme Court of Queensland under Part 4 of the Property Law Act 1974 (Qld) to hold co-owned property on trust and effect its sale. Once appointed, the trustee has authority to sell the property without the consent of either co-owner. The proceeds of sale are applied first to the trustee’s costs and any encumbrances on the property, with the balance distributed to the co-owners in accordance with their respective interests. Any disputes about those proportions, or about contribution and accounting claims, can be determined by the court at the same time or separately.
What is the difference between a joint tenancy and a tenancy in common?
Under a joint tenancy, co-owners hold the property together without defined shares. If one joint tenant dies, their interest passes automatically to the surviving co-owner or co-owners by right of survivorship, regardless of what the deceased’s will says. Under a tenancy in common, each co-owner holds a defined share, which does not need to be equal. On the death of a co-owner, their share passes under their will or the intestacy rules. The distinction affects how disputes are structured, what remedies are available, and what happens to the property if one co-owner dies during the dispute. Joint tenancies can be severed, converting the ownership to a tenancy in common, by a unilateral act of one co-owner. This is sometimes a necessary early step in a co-ownership dispute.
What if my co-owner and I hold unequal shares but the title does not reflect our actual contributions?
The legal title is the starting point but it is not always the end of the analysis. Where one co-owner has contributed more than their legal share reflects, equity may recognise a larger beneficial interest through a constructive trust or resulting trust. These claims are fact-intensive and depend on the financial contributions made, any agreement between the parties about how the property was to be held, and the conduct of the parties over the course of the ownership. We advise on equitable claims alongside the primary remedy sought and build the evidentiary foundation for these arguments from the outset.
If one co-owner has been paying the mortgage while the other has not, what can they recover?
A co-owner who has paid more than their proportionate share of the mortgage, rates, insurance or maintenance costs may be entitled to a contribution from the other co-owner. This is a separate claim from the primary remedy of sale or partition and must be pleaded and established with appropriate evidence. We advise on contribution claims alongside the primary dispute and ensure that a client’s full financial entitlement is quantified and pursued.
My co-owner has lodged a caveat on the property. What can I do?
A caveat lodged on co-owned property prevents dealings with the title until it is removed. If the caveat is lodged without a proper legal basis, you can apply to the Supreme Court to have it removed. If the caveat reflects a genuine claim to an interest in the property, the underlying dispute needs to be resolved. We advise on the basis of the caveat, whether it can be challenged, and how the caveat intersects with the broader co-ownership dispute.
Can a co-ownership dispute be resolved without going to court?
Yes. Many co-ownership disputes are resolved through negotiation or mediation without formal proceedings. A well-prepared legal position, backed by a credible willingness to litigate, consistently produces better negotiated outcomes and at lower cost. We advise on the realistic litigation risk on both sides and use that analysis to negotiate effectively. Where the other co-owner is unwilling to engage, court proceedings may be the only path, but most disputes that reach a specialist litigation firm resolve before judgment.
Does Boyle Litigation act in co-ownership disputes outside Queensland?
Yes. Boyle Litigation is based in Brisbane and acts for clients nationally. Property law is primarily state-based, so the applicable legislation depends on where the property is located. We act in co-ownership disputes in Queensland courts and advise on matters in other Australian jurisdictions, working with local counsel where required.
