A joint ownership property sale in NSW is defined as the process by which two or more co-owners transfer title to real estate, with the legal outcome determined by which ownership structure they hold. NSW property law recognises two distinct forms of co-ownership: joint tenancy and tenancy in common. Each carries different rights, obligations, and sale procedures under the Conveyancing Act 1919 (NSW). Getting the ownership type wrong at the start of a sale can cost you time, money, and in some cases, your share of the proceeds.
The Conveyancing Act 1919 (NSW) governs how co-owned property is sold, and Section 66G is the critical provision for owners who cannot agree. It allows any co-owner to apply to the NSW Supreme Court to appoint trustees and force a sale. Revenue NSW also plays a role, assessing land tax and stamp duty obligations that arise from the transfer of title. Understanding these frameworks before you list the property protects your financial position from the outset.
What are the different types of joint property ownership in NSW?
The ownership type you hold determines your rights when selling co-owned property. NSW recognises two structures, and they operate very differently in practice.
Joint tenancy means all owners hold the property as a single, indivisible unit. No owner holds a defined percentage share. The right of survivorship applies, meaning if one owner dies, their interest passes automatically to the surviving owners, not to their estate. Joint tenants have right of survivorship; tenants in common can allocate shares and transfer them separately. This distinction shapes every aspect of the sale process, from consent requirements to proceeds distribution.

Tenancy in common gives each owner a defined share, which may be equal or unequal. A tenant in common can sell their individual share without the other owners’ consent, but cannot unilaterally sell the entire property without agreement. This is the structure most commonly used in investment property purchases and family arrangements where parties contribute different amounts.
| Feature | Joint tenancy | Tenancy in common |
|---|---|---|
| Defined shares | No | Yes |
| Right of survivorship | Yes | No |
| Can sell share separately | No | Yes |
| Proceeds distribution | Equal | Proportional to share |
| Estate planning flexibility | Limited | High |
Choosing joint tenancy or tenants in common is a strategic estate planning decision that affects both inheritance and sale rights. Owners can change their structure after purchase through a legal transfer of title, which affects future sale and inheritance strategies. West Legal & Associates regularly advises clients on which structure best fits their circumstances before they commit to a purchase.
Pro Tip: If you purchased with a partner or family member and never discussed ownership structure, check your title documents now. The default recorded at NSW Land Registry Services controls your legal rights, not any verbal agreement you may have made.

Pro Tip: West Legal & Associates holds PEXA certification, which means property settlements are processed electronically and efficiently. Ask your solicitor whether your settlement will be conducted through PEXA to avoid delays.
How do you manage disagreements between co-owners during the sale?
Disputes between co-owners are one of the most common and costly problems in the joint property sale process. The risk is highest when no formal agreement exists.
Without a written co-ownership agreement, co-owners have no agreed framework for resolving deadlocks. Forced sales under Section 66G often involve high legal costs, delays, and emotional stress, making preventative legal planning the most effective approach. A court application under Section 66G of the Conveyancing Act 1919 (NSW) allows any co-owner to seek a court order appointing trustees to sell the property, even if other owners object.
The NSW Supreme Court may prefer ordering a sale of the entire property rather than a physical partition into separate parcels. Partition is technically available but rarely granted because it is less practical and financially beneficial for all parties. The court’s preference for sale means a dissenting co-owner cannot simply block the process indefinitely.

FAQ
What is the difference between joint tenancy and tenancy in common in NSW?
Joint tenancy means all owners hold the property as one indivisible unit with the right of survivorship. Tenancy in common gives each owner a defined share that can be transferred or sold separately.
Can one co-owner force the sale of a jointly owned property in NSW?
Yes. Under Section 66G of the Conveyancing Act 1919 (NSW), any co-owner can apply to the NSW Supreme Court to appoint trustees and order the sale of the property, even if other owners object.
Do all co-owners need to agree to sell a property in NSW?
For a voluntary sale, all co-owners must agree. If agreement cannot be reached, a court application under Section 66G is the legal mechanism to proceed with the sale without unanimous consent.
