Joint Tenants vs Tenants in Common NSW: Can Either Owner Sell Their Share?

In NSW, a tenant in common can generally transfer their stated fractional interest without selling the whole property, although mortgages, caveats, co-ownership agreements and practical buyer demand may restrict the transaction.

A joint tenant cannot simply sell a fixed “half” while leaving the joint tenancy untouched. They may transfer or sever their interest, usually converting it into a tenancy in common.

Selling the entire property normally requires every registered owner’s cooperation or a court-ordered pathway.

Property co-ownership often appears straightforward while the owners remain aligned. A couple buys an apartment together. Siblings retain an inherited Sydney house. Two investors acquire a development property. One owner contributes more cash, another manages the renovation, and both expect to decide what happens later.

The structure becomes far more consequential when one owner wants to exit, refinance, renovate, occupy or sell while the other does not.

The first question is not simply, “Who paid what?” It is what the NSW land title records.

The title determines whether the owners are registered as joint tenants or tenants in common, whether specific fractions are recorded and what legal interest can be transferred.

The Title Structure Determines What Is Actually Saleable Joint tenancy and tenancy in common are both forms of co-ownership, but they do not divide the property in the same way.

Under a joint tenancy, the owners hold the property jointly and the title does not ordinarily allocate a separate registered percentage to each joint tenant. Its defining feature is the right of survivorship.

When one joint tenant dies, the surviving joint tenant or tenants ordinarily take the deceased owner’s interest through the title rather than through the deceased owner’s will.

Under a tenancy in common, each registered owner holds a distinct fractional interest. Those fractions may be equal, such as 50/50, or unequal, such as 70/30.

The NSW Trustee and Guardian explanation of co-ownership notes that a tenant in common’s percentage forms part of that owner’s estate rather than automatically passing to the other co-owner.

Issue: Registered ownership Joint tenants: The property is held jointly, without separately recorded fractional shares in the usual form. Tenants in common: Each owner has a stated fractional interest, which may be equal or unequal. Issue: Death of an owner Joint tenants: The right of survivorship ordinarily passes the interest to the surviving joint tenant or tenants. Tenants in common: The deceased owner’s share forms part of their estate. Issue: Sale of the whole property Joint tenants: All registered owners normally need to participate unless a court or another legal authority intervenes. Tenants in common: All registered owners normally need to participate unless a court or another legal authority intervenes. Issue: Transfer of one owner’s interest Joint tenants: A transfer or severance can end the joint tenancy in relation to that interest. Tenants in common: The owner can generally transfer their recorded fractional interest, subject to legal and financial constraints. Issue: What the buyer receives Joint tenants: An interest created through the severance or transfer process, not an exclusive physical half of the property. Tenants in common: An undivided fractional interest in the entire property, not automatic ownership of a particular bedroom, floor or section. Can a Tenant in Common Sell Their Share? A tenant in common can generally sell, transfer or otherwise deal with their registered fractional interest without transferring the other co-owner’s interest.

The State Library of NSW co-ownership guidance describes tenants in common as holding distinct shares that they may deal with and dispose of.

That legal ability does not mean the owner can sell the entire dwelling, promise vacant possession of the whole property or allocate a particular physical area to the buyer.

A 50 per cent tenant-in-common interest is an undivided interest across the whole title. It is not automatically:

The front half of a house. One bedroom in an apartment. One level of a terrace. Half of a backyard. A separate strata lot. Unless the land has been legally subdivided, separately titled or made subject to an enforceable occupancy arrangement, every tenant in common generally has a right to possession of the property as a whole alongside the other co-owners.

This distinction is central to saleability.

A third-party purchaser is not simply buying “half a Sydney house”. The purchaser is entering an ongoing legal and operational relationship with whoever remains on title.

The Other Owner’s Consent May Not Be the Only Constraint Even where the other tenant in common does not need to sign away their own interest, a proposed share sale can still be affected by:

A registered mortgage over the title. A caveat or court order. A written co-ownership agreement. A right of first refusal or buyout mechanism. Family law proceedings. Bankruptcy or estate-administration issues. An existing residential or commercial lease. Strata records, by-laws or outstanding levies. Unpaid renovation liabilities. The buyer’s ability to obtain finance. The practical question is therefore not only whether a transfer form can be prepared.

It is whether the title, lender, contract, purchaser and settlement process can all support the proposed change.

Can a Joint Tenant Sell Their Interest? A joint tenant does not ordinarily have a separately recorded “50 per cent share” that can simply be advertised while the joint tenancy remains unchanged.

A joint tenant may, however, take steps that sever the joint tenancy or transfer their interest.

Severance removes the right of survivorship for the severed interest and changes the co-ownership relationship, generally creating a tenancy in common in relation to that interest.

NSW Land Registry Services provides formal pathways for a transfer severing a joint tenancy .

Relevant unilateral severance dealings can include notice requirements so that the other registered joint tenant or tenants are informed.

The sequence matters.

A joint tenant should not sign a sale contract described as the sale of a fixed percentage without first confirming:

What interest is currently registered. Whether severance is required before or as part of the transfer. What notices and supporting evidence are needed. Whether a mortgagee or another interest holder must participate. How the contract describes the interest being sold. Once the joint tenancy has been severed, the ownership and estate-planning consequences change.

The former joint tenant’s interest no longer passes automatically through survivorship in the same way.

A Share Sale Is Not the Same as Selling the Property The distinction between selling one interest and selling the entire title is frequently lost during family, investment and relationship disputes.

One co-owner cannot ordinarily sign a contract promising to transfer 100 per cent of the property when another registered owner has not agreed to sell.

A whole-property sale normally requires every registered proprietor to execute the required documents and provide the authorities needed for settlement.

A share sale, by comparison, changes the identity of one co-owner while leaving the remaining owner on title.

Operational reality: A buyer may be willing to purchase the whole property at full market value but unwilling to buy only one undivided share. The seller’s legal ability to transfer an interest does not create a liquid or conventional market for that interest.

Why a 50 Per Cent Share May Not Be Worth 50 Per Cent of the Property Owners sometimes assume that a half interest in a property worth $2 million should sell for $1 million.

A standalone share can be worth materially less to an external buyer because it carries reduced control, uncertain occupation arrangements and a continuing relationship with the remaining co-owner.

A purchaser assessing an undivided interest may ask:

Who currently occupies the property? Can rent be collected, and how is it divided? Who pays the mortgage, strata levies, rates, insurance and maintenance? Can the buyer move in? Are renovations planned or already underway? Can the remaining co-owner block a refinance or whole-property sale? Is there a written co-ownership agreement? Will future litigation be required to exit the investment? These questions create valuation and finance friction.

A valuation of the whole property does not, by itself, determine the open-market value of a minority or co-controlled interest.

The Mortgage Can Control the Transaction in Practice Many co-owned Sydney properties are subject to a mortgage covering the entire title.

The registered ownership percentages and the borrowers’ contractual liabilities are not necessarily the same thing.

Two owners may each hold a 50 per cent property interest while both remain jointly and severally liable under the loan.

Selling one title interest does not automatically release that person from the mortgage debt.

Before a share is marketed, the owners should establish:

Whether the loan is secured over the whole property. Which owners are borrowers and guarantors. Whether the existing lender will consent to the transfer. Whether the purchaser can refinance or replace the outgoing borrower. Whether the mortgage must be discharged and a new mortgage registered. How settlement funds will be applied. NSW Land Registry Services separately addresses transfers where a mortgage is recorded on the Register .

The land-title pathway and the bank’s loan-approval pathway should be treated as connected workstreams rather than consecutive administrative tasks.

Co-Ownership Agreements Can Change the Exit Sequence The title records legal ownership, but a co-ownership agreement may regulate how the owners have agreed to use, fund and eventually exit the property.

A properly drafted agreement may include:

A right of first refusal for the remaining owner. A valuation method. A deadline for a buyout election. A process for appointing an independent valuer. Rules for mortgage, rates and strata contributions. Renovation approval thresholds. Occupation payments or rental distribution. A mechanism for recovering unequal capital contributions. A forced-sale process after a specified deadlock period. A seller who ignores those provisions may create a contractual dispute even where a land transfer would otherwise be technically possible.

The agreement should therefore be reviewed before the interest is advertised or a price is accepted.

What Happens When the Owners Cannot Agree? When one owner wants to sell the whole property and another refuses, negotiation, refinancing and a structured buyout are usually more controlled than immediate litigation.

Common resolution pathways include:

Internal buyout. One owner buys the other owner’s interest using an agreed or independently assessed value. Agreed open-market sale. Both owners appoint an agent, approve a sale campaign and sell the whole property. Sale of an individual interest. One co-owner transfers their share to a third party, subject to title, contract and finance constraints. Partition or restructuring. Where legally and physically possible, jointly held land may be divided or restructured. Court application. A co-owner may seek a statutory trust for sale or partition under section 66G of the Conveyancing Act 1919. The Section 66G Pathway Section 66G of the Conveyancing Act 1919 provides a Supreme Court pathway for property held in co-ownership to be placed on a statutory trust for sale or partition.

In practical terms, the court may appoint trustees to take control of the sale process when the owners cannot cooperate.

The net proceeds can then be dealt with after sale costs, secured debts and any determined adjustments are addressed.

A section 66G application should not be treated as a simple property-listing instruction.

It can involve:

Court filing and legal representation. Trustee appointment and remuneration. Valuation or sale-method disputes. Access and occupation issues. Claims for mortgage, rates, repairs or renovation contributions. Possession and vacant-handover planning. The risk that legal and sale costs reduce the final proceeds. The availability, timing and financial outcome of a court application depend on the specific facts.

Owners should obtain advice before relying on litigation as a pricing or negotiation strategy.

Transfer Duty and Other Transaction Costs Still Matter A transfer between existing co-owners, or from one co-owner to an external buyer, is not cost-free simply because only part of the property is changing hands.

Depending on the transaction, the parties may need to consider:

NSW transfer duty on the acquired interest. Valuation evidence. Registration and electronic settlement fees. Lender discharge, consent and refinancing costs. Capital gains tax advice. Land tax implications. Legal and conveyancing fees. Agent fees if the interest is marketed. Adjustments for rates, strata levies, rent or occupation. Revenue NSW states that transfer duty generally applies when property is acquired in NSW, while specific exemptions and concessions may apply to eligible transactions, including certain transfers between spouses or de facto partners.

Where co-owned land is divided so that owners take separate property, Revenue NSW also has a specific duty framework for partitions of land .

A proposed arrangement should be assessed on its actual legal structure rather than described informally as a “swap” or “buyout”.

Sydney Scenario One: Siblings Own an Inherited House Consider two siblings registered as tenants in common in equal shares after an estate is administered.

One sibling lives in the property while the other wants their inheritance released.

The non-occupying sibling may be able to sell their 50 per cent interest, but an external purchaser would become co-owner with the occupying sibling.

That is likely to be less commercially attractive than a whole-property sale or an internal buyout.

Before agreeing on a price, the parties may need to reconcile:

Mortgage payments made by either sibling. Council rates and insurance. Maintenance and renovation expenditure. Rental income, if any. The value of exclusive occupation. Estate-related obligations. This situation is distinct from the duty treatment examined in Elyment’s guide to NSW deceased-estate property transfers .

Once the beneficiaries are registered as co-owners, the operational problem becomes one of exit structure, valuation and control.

Sydney Scenario Two: A Separating Couple Holds as Joint Tenants A separating couple may assume each already owns a fixed half that can be independently sold.

The title may instead show a joint tenancy with a continuing right of survivorship.

Before either party signs a sale or buyout arrangement, the workflow should account for:

Whether the joint tenancy should be severed. Any family law advice or orders. The existing mortgage and borrower liabilities. Who remains in occupation. The valuation date and method. Whether one party can qualify to refinance alone. A rushed transfer can solve the title issue while leaving the outgoing owner exposed under the loan.

Title, finance and settlement documentation must reach the same commercial result.

Sydney Scenario Three: Investors Own an Apartment 70/30 Two investors may be registered as tenants in common in unequal shares, reflecting different capital contributions.

If the 30 per cent owner wants to exit, the title identifies the interest that can potentially be transferred.

The transaction can still become difficult where:

The apartment is tenanted. The mortgage secures the whole title. The owners have personally guaranteed the loan. Major strata works are pending. Special levies have been issued. A renovation has been ordered but not completed. A buyer of the 30 per cent interest will price not only the apartment, but also the governance relationship with the 70 per cent owner.

Why Co-Ownership Becomes a Renovation and Project-Delivery Issue Ownership disputes frequently reach contractors only after deposits have been paid, materials ordered or strata applications lodged.

One co-owner may instruct flooring removal, painting, a kitchen replacement or concrete rectification while another disputes the cost, design or authority to proceed.

The contractor may then face uncertainty over access, payment and variation approval.

Before substantial works commence on co-owned property, project teams should confirm:

Who is registered on title. Who has authority to approve the scope. Whether every owner has approved major expenditure. Which party is contracting and responsible for payment. Whether a sale, refinance or court process is already underway. Whether strata or council approvals are required. Who can provide access and vacant possession. Whether the work will be completed before valuation, marketing or settlement. This is particularly important for disruptive scopes such as carpet or tile removal, concrete grinding, floor levelling, waterproofing, epoxy installation and whole-property painting.

Once finishes have been removed, pausing the project can expose the property to additional reinstatement, storage and access costs.

Buyers and co-owners arranging works around a transaction should also review Elyment’s guidance on settlement delays when renovation trades are already booked .

The Pre-Sale Review That Should Happen Before Marketing A structured review can identify whether the proposed transaction is a genuine share sale, an internal buyout, a severance, a partition or a sale of the whole property.

Order and review the current title search. Confirm the registered names, tenancy structure, fractional shares, mortgage, caveats and other recorded interests. Define what the owner intends to sell. Separate a proposed interest transfer from a sale of the whole property. Review co-ownership and finance documents. Check buyout rights, valuation mechanisms, lender requirements and personal loan liabilities. Establish occupation and access. Confirm who lives at the property, whether it is leased and what possession can lawfully be offered. Reconcile property expenditure. Record mortgage payments, rates, levies, rent, repairs and capital works without assuming every payment automatically changes title percentages. Obtain valuation and tax advice. Distinguish the value of the whole property from the likely market value of the individual interest. Sequence severance, contract and finance approvals. Do not market a fixed share under a joint tenancy without confirming how the interest will be legally created and transferred. Coordinate renovation and settlement commitments. Avoid placing contractors, strata managers or purchasers into an unresolved ownership dispute. Questions a Prospective Share Buyer Should Ask Question: What exact fraction will appear on title? Why it matters: The contract should match the interest that can be registered. Question: Who will remain as co-owner? Why it matters: The purchaser is entering a continuing ownership relationship. Question: Who occupies the property? Why it matters: A title interest does not automatically provide exclusive occupation. Question: Is there a co-ownership agreement? Why it matters: It may govern use, costs, transfers, valuations and future sale rights. Question: Is the property mortgaged? Why it matters: The lender and refinancing structure may determine whether settlement can occur. Question: Are there leases, caveats or court proceedings? Why it matters: Existing interests can affect possession, registration and risk. Question: Are renovations or strata works pending? Why it matters: Future levies and incomplete works can change the effective acquisition cost. Question: How can the purchaser exit later? Why it matters: A share that is difficult to acquire may also be difficult to resell. What NSW Property Owners Should Understand A tenancy in common gives an owner a defined fractional interest that can generally be transferred.

A joint tenancy requires a more careful analysis because the owners hold jointly and the right of survivorship remains until the tenancy is severed or otherwise brought to an end.

Neither structure allows one owner to sell another owner’s interest.

Neither turns an undivided percentage into ownership of a specific room or section.

Neither removes the need to coordinate mortgages, occupation, tax, contracts and settlement.

The strongest exit pathway is usually the one designed before conflict escalates.

Clear title analysis, independent valuation, documented contributions, finance approval and controlled project sequencing can prevent a technically possible transfer from becoming an operationally failed transaction.

Request a co-ownership and property project review from Elyment : confirm the title, finance and delivery pathway before a property share is marketed, transferred or tied to renovation commitments.

Review ownership structure, conveyancing steps, lender dependencies, strata considerations, access, project sequencing and settlement readiness with Elyment.

Frequently Asked Questions Can one tenant in common sell their share without the other owner agreeing? Generally, a tenant in common can transfer their own registered fractional interest without transferring the other owner’s interest.

The transaction may still be restricted by a mortgage, caveat, court order, co-ownership agreement or finance requirement.

Can a joint tenant sell their half of a NSW property? A joint tenant does not ordinarily hold a separately recorded half while the joint tenancy continues.

They may be able to transfer or sever their interest, which generally changes the ownership to a tenancy in common in relation to that interest.

Can one co-owner sell the entire property? Not ordinarily.

A voluntary sale of the whole property normally requires every registered proprietor to participate.

Where owners are deadlocked, a co-owner may obtain advice about a Supreme Court application under section 66G of the Conveyancing Act 1919.

Does buying a 50 per cent share give the buyer half of the house? No.

A tenant-in-common interest is ordinarily an undivided share across the whole property.

It does not automatically give the buyer exclusive ownership of a particular bedroom, level, backyard or other physical section.

Does transferring a share remove the seller from the home loan? Not automatically.

Ownership of the title and liability under the loan are separate issues.

The lender may require refinancing, a new loan approval, a discharge or other documentation before releasing an outgoing borrower.

Should co-owners approve renovations together? Major works should be authorised and documented before contractors are engaged.

The owners should confirm scope approval, payment responsibility, access, strata requirements and what will happen if the property is sold or refinanced before completion.
