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

Most guides explain this choice for wills and estates. If you're buying with a partner, friend or sibling, it's a different decision — about unequal shares, exits, and what happens if one of you dies.

The box you tick at settlement matters more than it looks

Somewhere in the conveyancing paperwork, usually amid a pile of other signatures, Australian co-buyers choose how they'll hold the title: as joint tenants or as tenants in common. Plenty of people let the conveyancer default it and find out years later what they picked. The choice decides whose share is whose, what you can each do with it, and where the property goes when one of you dies — so it's worth the ten minutes it takes to choose deliberately.

Most articles on this topic are written for estate planning. This one is written for the moment that actually matters most: when you're buying with someone.

The difference in one minute

Joint tenants own the whole property together, without separate shares. The defining feature is the right of survivorship: when one joint tenant dies, their interest passes automatically to the surviving owner(s) — outside the will, outside the estate, immediately.

Tenants in common each own a defined share — 50/50, 60/40, 75/25, whatever you record. Your share is yours: you can leave it in your will, and (subject to your agreement with your co-owners) sell it or borrow against it. There is no survivorship; a deceased owner's share goes to their heirs.

Everything else about the choice follows from that one difference.

Why couples often pick joint tenancy

For a couple buying a home with merged finances, survivorship is usually the point: if one dies, the other owns the home outright, instantly, without probate delays. Equal ownership matches how they see the purchase. That's why joint tenancy is the traditional default for spouses.

But note what you give up: joint tenancy cannot record unequal shares. If one partner put in $150,000 and the other $50,000, joint tenancy treats you as owning the place equally anyway. Couples with genuinely unequal contributions — especially later-in-life couples with children from earlier relationships who want their share to pass to those children, not automatically to a partner — often belong in tenants in common despite the tradition.

Why friends and siblings should almost always pick tenants in common

Run survivorship through a friendship and the problem is obvious: two mates buy a unit as joint tenants, one dies at 34, and his half — the half his family assumed was part of his estate — belongs entirely to his co-owner. No will can override it.

Tenants in common fixes all of it at once:

• Unequal shares are recorded. If the deposits were unequal, the title can say 65/35 instead of pretending otherwise.
• Your share is inheritable. It passes under your will like the asset it is.
• Exits are cleaner. A tenant in common's share can be valued and bought out without dissolving the whole arrangement.
• The lending can match. Property share loans — separate loans mirroring the title split — assume defined shares to mirror.

Can you have unequal shares as joint tenants?

No. Equality is inherent to joint tenancy — that's not lender policy, it's the nature of the tenure. The moment you want 60/40, you want tenants in common. (And if you're 50/50 tenants in common, you keep will-ability and clean exits anyway; the only thing you lose versus joint tenancy is automatic survivorship, which between non-spouses is usually the thing you *want* to lose.)

Can you change your mind later?

Yes. A joint tenancy can be severed — converted to a tenancy in common — and severing unilaterally is possible in every state, though the process and paperwork differ. It happens routinely on relationship breakdown, precisely because nobody mid-divorce wants their ex inheriting by survivorship. Going the other way (tenants in common merging into joint tenancy) is also possible by transfer. Both directions can have stamp duty and CGT considerations depending on your state and whether shares shift, so get conveyancing advice before touching the title. The cheaper path is choosing correctly the first time.

What tenants in common still doesn't solve

The title records shares. It says nothing about who pays the rates, what happens when someone stops contributing, how a buyout gets valued, or who approves a renovation. That's the job of a co-ownership agreement — and then of actually running the property by it, which is the layer Laddered handles: contributions tracked against the recorded shares, expenses split by the rules you agreed, one ledger everyone trusts.

The quick decision guide

• Married or de facto, merged finances, equal contributions, want survivorship: joint tenants is the conventional fit.
• Any unequal contribution you want recognised: tenants in common, shares recorded to match.
• Friends, siblings, or any co-buyers with separate financial lives: tenants in common, near-universally.
• Blended families or estate complexity: tenants in common, so your will controls your share.

This is general information, not legal advice. Tenure, severance mechanics, duty and land tax detail vary by state — confirm your choice with your conveyancer or solicitor before settlement, when changing it is still free.
