Buying property with a partner, friend, or family member is one of the most common ways Australians enter the property market, whether that's a couple buying their first home together or two friends going in on an investment property. But amid the excitement of finding the right property, one important decision often gets rushed, or skipped entirely: how you actually structure the ownership.

How you hold title matters far more than most buyers realise, and it can be genuinely difficult and expensive to change later. This guide walks through the main ownership structures available to joint purchasers in Australia, what they mean in practice, and why it's worth getting proper advice before you sign anything.

Why Ownership Structure Deserves Real Thought

When you buy property with someone else, you and your co-owner will be recorded on the title in one of a small number of ways. That choice affects what happens if one of you wants to sell, what happens to the property if one owner passes away, how profits and losses are shared for tax purposes, and how the property is treated if the relationship or arrangement breaks down.

Many buyers default to whatever their conveyancer suggests, or simply mirror what a friend or family member did, without understanding the practical implications. Getting this decision right at the outset can save significant stress, cost, and conflict later.

The Two Main Ways to Hold Property Jointly in Australia

Joint Tenants

Under a joint tenancy, both owners hold an equal and undivided interest in the property. Neither owner holds a specific, separate share. Instead, the property is owned jointly as a whole.

The defining feature of joint tenancy is the right of survivorship. If one owner passes away, their interest in the property automatically transfers to the surviving owner, regardless of what their will says. This structure is common among married couples and de facto partners, since it ensures the property passes directly to the surviving partner without needing to go through the deceased's estate.

Because ownership isn't divided into separate shares, joint tenants generally cannot leave their portion of the property to someone else in their will. The right of survivorship overrides those instructions.

Tenants in Common

Under a tenants in common structure, each owner holds a specific, defined share of the property. This might be an equal 50-50 split, or it could reflect unequal contributions, such as 70-30 or 60-40, depending on how much each party contributed to the purchase.

Unlike joint tenancy, there is no automatic right of survivorship. If one owner passes away, their share of the property forms part of their estate and is distributed according to their will, rather than automatically passing to the co-owner. This structure is often preferred by friends or family members purchasing an investment property together, by couples who have contributed unequal amounts to the purchase and want that reflected in their ownership share, and by people in blended families who want to ensure their share of the property passes to their own children rather than automatically to a co-owner.

Why the Choice Between the Two Matters So Much

The right structure depends entirely on your personal circumstances and what you're trying to achieve. A married couple who contributed equally and want the property to pass automatically to the surviving partner will often lean toward joint tenancy. Two friends buying an investment property together, who contributed different amounts and want their individual share to pass to their own family, will typically be better suited to tenants in common.

It's also worth understanding that these structures can affect how capital gains tax is calculated when the property is eventually sold, since each tenant in common is generally assessed on their specific share of any gain, whereas joint tenants are typically treated as owning equal shares regardless of what each person actually contributed.

This is general information only, and every situation is different. It's genuinely worth discussing your specific circumstances with a solicitor or conveyancer, and your accountant, before deciding on a structure, rather than assuming one option is automatically the right choice.

Beyond the Title: Consider a Co-Ownership Agreement

Regardless of which ownership structure you choose, a separate co-ownership agreement is worth serious consideration, particularly for friends, family members, or anyone buying an investment property together rather than a family home.

A well-drafted co-ownership agreement can set out how expenses like the mortgage, rates, insurance, and maintenance will be shared, what happens if one owner wants to sell their share, how disputes will be resolved if the co-owners disagree on a decision, what happens if one owner wants to rent out or occupy the property and the other doesn't, and an agreed process for one owner buying out the other if the arrangement needs to end.

These conversations can feel uncomfortable to have upfront, especially between friends or family, but they are far easier to navigate before a problem arises than during one. A solicitor experienced in property co-ownership can draft an agreement tailored to your specific arrangement.

Questions to Work Through Before You Buy Together

• Are you contributing equally to the deposit, ongoing mortgage repayments, and other costs, or is the split uneven?

• If one of you wanted to sell your share in the future, how would that process work?

• If the relationship or partnership between you changed, what would happen to the property?

• Do you want your share of the property to pass automatically to your co-owner, or to your own family or estate, if something happened to you?

• Are you both borrowing under the same loan, and how does that affect your individual financial position and future borrowing capacity?

Working through these questions honestly before you buy, ideally with the input of a solicitor and accountant, sets the foundation for a much smoother co-ownership experience.

How a Buyer's Agent Supports Joint Purchases

Buying property with someone else adds a layer of complexity to an already significant decision. A buyer's agent can help joint purchasers by making sure the property itself genuinely suits both parties' goals, coordinating with your solicitor and mortgage broker so the purchase, finance, and title structure are aligned, and providing objective, unemotional guidance during negotiations, which can be particularly valuable when two parties are trying to agree on a purchase together.

While the ownership structure itself is a legal and financial decision best made with your solicitor and accountant, having the right property strategy and negotiation support alongside that ensures the whole process runs smoothly from start to finish.

Ownership structures have important legal and tax implications that vary depending on individual circumstances. Buyers should seek advice from a qualified solicitor, conveyancer, or accountant before deciding how to structure a joint property purchase.

Frequently Asked Questions

Can we change our ownership structure after we've already bought the property?

It is possible to change from joint tenants to tenants in common, or vice versa, after purchase, but the process can involve legal costs, and in some cases stamp duty or capital gains tax implications depending on the state and circumstances. It's generally far simpler and less costly to choose the right structure from the outset, which is why it's worth getting advice before you buy rather than after.

What happens if we buy as tenants in common and one of us wants to sell?

Under a tenants in common structure, each owner can generally sell, transfer, or leave their share of the property independently, though the practicalities depend on your specific co-ownership agreement and, if you have one, any provisions it includes for this scenario. This is exactly why a co-ownership agreement is worth having in place before you buy, so the process is clear if this situation arises.

Is one ownership structure better than the other for tax purposes?

Neither structure is universally better for tax purposes. It depends on your individual circumstances, including your respective incomes, how much each party contributed to the purchase, and your long-term plans for the property. A tenants in common structure can allow income and capital gains to be split according to ownership percentage, which may suit some situations. An accountant can advise on which structure best suits your specific financial position.
