Tenants in Common vs Joint Tenants: Which Should Co-Buyers Choose?

When two or more people buy property together in Australia, they must choose how to hold it on the title: as joint tenants or as tenants in common. It sounds like paperwork, but the choice affects what happens if an owner dies, whether shares can be unequal, and how cleanly someone can exit. Here's how to decide.

The one-line difference

• Joint tenants own the whole property together, in equal shares, with a right of survivorship.
• Tenants in common each own a distinct share (which can be unequal), with no survivorship.

Everything else flows from those two ideas.

Joint tenants, explained

As joint tenants, the law treats you as owning the entire property jointly rather than in slices. Two features define it:

1. Equal shares. You can't be "70% joint tenants" — joint tenancy is inherently equal.
2. Right of survivorship. If one owner dies, their interest passes automatically to the surviving owner(s), outside the will. The property doesn't form part of the deceased's estate.

This is why married and de facto couples usually choose joint tenancy: if one partner dies, the survivor automatically owns the home, with no estate delay.

Tenants in common, explained

As tenants in common, each owner holds a separate, definable share — commonly recorded on title as a fraction or percentage (for example, 60/40 or 1/3 each). Two features define it:

1. Unequal shares allowed. The split can reflect what each person actually contributed.
2. No survivorship. When an owner dies, their share passes according to their will, not automatically to the other owners.

This is the usual choice for friends, siblings, parents and adult children, and investment partners — anyone whose contributions are unequal or whose relationship isn't a couple.

Side-by-side

| Question | Joint tenants | Tenants in common | |---|---|---| | Can shares be unequal? | No (always equal) | Yes | | What happens on death? | Passes to survivor(s) automatically | Passes via the will | | Forms part of the estate? | No | Yes | | Typical for | Couples | Friends, family, investors | | Can you sell your share alone? | Generally no without severing | Yes (subject to any agreement) |

Why unequal shares matter

Imagine two friends buy a $700,000 apartment. One contributes a $90,000 deposit; the other contributes $30,000. Under joint tenancy, the law treats them as 50/50 regardless — the bigger contributor has effectively gifted equity. Under tenancy in common, the title can record their shares to reflect the real contributions, so each person's stake is protected.

This is the core reason most non-couple co-buyers choose tenancy in common. For the full picture of contributions and fair equity, see our complete guide to co-ownership in Australia.

Tax and investment angles

For an investment property, the structure also shapes tax. Rental income and deductions, and any future capital gain, are generally apportioned according to each owner's legal share on title — not who paid a particular expense from their account. That makes the title split a decision with long tax consequences, so it's worth getting right at purchase. Always confirm your position with a registered tax agent.

Can you change your mind later?

Yes, but it's a formal process:

• Severing a joint tenancy converts it to a tenancy in common (often done when a relationship breaks down, so survivorship no longer applies).
• Changing shares under a tenancy in common, or moving the other way, can trigger stamp duty and potentially capital gains tax on the transferred portion.

Because changes can be costly, choose deliberately at the start.

So which should you choose?

A simple rule of thumb:

• A couple, equal contributions, you want the survivor to inherit automatically → joint tenants.
• Unequal contributions, friends/family/investors, or you want to control who inherits your share → tenants in common.

Whatever you choose, back it with a co-ownership agreement that records contributions and an exit process. Read how to buy property with a friend or partner for the practical steps.
