Is a housemate agreement legally binding in Australia?
A housemate agreement is a private contract between the people sharing a home, and it's designed to meet the requirements of a valid agreement under Australian contract law. Whether a specific clause is enforceable depends on its terms and the circumstances — it's not the same as a residential tenancy agreement, and SignedSorted isn't a law firm, so for high-value or complex disputes we recommend independent legal advice.
What's the difference between a housemate agreement and a lease?
A lease (residential tenancy agreement) is between a tenant and a landlord and is governed by your state's tenancy legislation — it's lodged, bonds are protected through a government scheme, and disputes go to your state tribunal. A housemate agreement is a private arrangement between the people actually living in the property, covering things a lease doesn't — like how bills are split, whose turn it is to clean, and what happens if someone wants to bring in a new housemate. Most share houses need both: a lease with the landlord, and a housemate agreement between the people in the house.
Do all housemates need to be on the lease for this to work?
No. A housemate agreement works whether everyone is on the lease, only one person is (the head tenant) and the others are subletting from them, or there's no formal lease at all. It documents the arrangement between the people in the house, separately from whatever tenancy arrangement exists with the landlord.
How do we handle the bond in a housemate agreement?
If the bond is lodged with the state bond authority under the lease, the housemate agreement can't override that — it can only record how the housemates have agreed to split the cost and share any refund between themselves. Keep the two separate: the lodged bond is between tenant(s) and landlord; your internal split is between housemates.
Can we include rules about guests and overnight stays?
Yes — this is one of the most common sources of housemate conflict, so it's worth being specific. Common approaches include a cap on consecutive nights before someone is considered a new occupant, a heads-up requirement for overnight guests, or a simple "be reasonable and communicate" clause for smaller households.
What happens if a housemate stops paying their share?
Your agreement should set out what happens next — typically a written reminder, a short grace period, and then a clear next step (which might include ending the arrangement). Since a housemate agreement is a private contract, unpaid amounts are generally recovered the same way as any private debt — starting with a letter of demand, and small claims tribunal if it isn't resolved.
How much notice should a housemate give before moving out?
There's no single legal minimum for informal share-house arrangements the way there is for a tenancy — it's whatever the household agrees to upfront, commonly 2 to 4 weeks. Putting a specific number in writing before anyone needs it avoids the awkward "how much notice is fair?" conversation happening during an actual falling-out.
Can a housemate agreement cover pets?
Yes. It can record whether pets are allowed at all, whether new pets need everyone's agreement, and who's responsible for any damage or cleaning a pet causes — useful even if the head lease is silent on pets, since that's a landlord-facing rule, not a housemate-facing one.
What if we need to replace a housemate partway through?
Your agreement can set out the process upfront — how much notice the leaving housemate gives, whether the remaining housemates need to approve the replacement, and how bond and unpaid bills get settled at handover. Agreeing this before someone actually needs to move out avoids most of the argument.
Does the agreement need to be signed by everyone in the house?
For it to reflect the actual arrangement, yes — every housemate it applies to should review and sign. SignedSorted sends each party a secure link to review, request changes, and e-sign, so nobody needs to be in the same room to get it done.
Is this different for a couple living together vs. a share house?
The same basic document works for both — a couple moving in together often uses it to document how rent, bills and larger shared costs are split, without the "tenancy" framing that can feel like the wrong fit for a relationship. It's the same underlying idea: get the money and household expectations in writing before there's a disagreement about them.
How long does it take to create one?
Most housemate agreements are drafted in a few minutes once you've described the arrangement — rent, bond split, bills, house rules, and any specific concerns. Each housemate then reviews and signs at their own pace.
