Co-Ownership Agreements in Queensland: A Complete Guide to Shared Property Ownership

  • Published: 15 January 2024
  • Last Updated: 3 February 2026
Co-ownership agreements in Queensland are essential legal documents that govern the shared ownership of a property between two or more individuals. These agreements are particularly important in situations where people decide to jointly invest in real estate, business ventures, or other assets. A well-structured co-ownership agreement can help prevent disputes, clarify ownership rights, and establish a framework for managing the property. In this article, we explore the key elements and benefits of co-ownership agreements for shared property ownership in Queensland.
If you’re looking for legal help with co-ownership agreements, contact Bennett Carroll Solicitors today. Our Brisbane, Gold Coast, Ipswich and Sunshine Coast offices are ready to assist you in safeguarding your property and interests.

What is a Co-Ownership Agreement?

A co-ownership agreement, often referred to as a co-owners, co-tenancy or joint ownership agreement, is a legally binding document that outlines the rights, responsibilities, and obligations of each co-owner concerning a shared asset. This asset can be anything from real estate properties (such as houses, apartments, or land) to businesses, vehicles, or even valuable personal items.

Who are Co-Ownership Agreements for?

These are increasingly vital for anyone pooling resources to buy property, which is becoming particularly common given the rising cost of Queensland real estate. You should consider a formal agreement if you are:

  • Friends or Siblings buying together to enter the market sooner.
  • Parents and Children where the “Bank of Mum and Dad” wants to protect their equity.
  • Investors pooling funds to purchase a real estate asset.

 

Key Elements of a Co-Ownership Agreement:

  • Ownership Shares: The agreement should specify the percentage of ownership each co-owner holds in the shared property. This is crucial for determining each party’s share of expenses, income, and decision-making authority.
  • Contributions: Co-owners typically make financial contributions to acquire and maintain the property. The agreement should detail each co-owner’s financial responsibilities, including the initial investment and ongoing expenses.
  • Management and Decision-Making: It’s important to establish a framework for decision-making within the co-ownership arrangement. This includes determining how major decisions will be made, such as selling the property or making significant improvements.
  • Use and Access: The agreement should outline how the shared property will be used and who has access to it. This might include rules for occupancy, rental, or use for business purposes.
  • Maintenance and Repairs: Co-owners must agree on how they will handle maintenance and repair costs. This can involve setting up a maintenance fund, specifying who is responsible for what, and establishing a process for approving and conducting repairs.
  • Dispute Resolution: In the event of conflicts or disagreements, the co-ownership agreement should provide a mechanism for dispute resolution, such as mediation or arbitration.

 

Benefits of Co-Ownership Agreements:

  • Legal Clarity: Co-ownership agreements provide a clear and legally binding framework for shared ownership, reducing the likelihood of misunderstandings and disputes.
  • Protecting Investments: These agreements protect each co-owner’s financial interests by specifying the terms of their investment and responsibilities.
  • Decision-Making Structure: Co-ownership agreements establish a structure for making critical decisions, ensuring that all co-owners have a say and that decisions are made collectively.
  • Property Management: They help ensure proper management of the property, including maintenance, repairs, and access rights.
  • Exit Strategies: Co-ownership agreements often address exit strategies, such as the sale of the property or the buyout of a co-owner’s share. This can be crucial when circumstances change.
