Who is responsible for unpaid rent in a share house?

Living in a share house can be a blast. You’ve got your own space, someone to split bills with and maybe even a mate to binge-watch TV with.

But when someone doesn’t pay their rent, things can get messy fast.

So, who’s actually responsible for unpaid rent in a share house?

The answer depends on your rental agreement.

Joint vs individual lease

This is the first thing to check.

In a joint lease, everyone listed on the rental agreement shares equal responsibility for the whole rent. If one housemate doesn’t pay their portion, the rest of you are still legally required to cover the full amount.

Even if it’s not your fault, your landlord or property manager can ask you to cough up the difference. This is within their legal right.

In contrast, if you’re on individual agreements (sometimes called rooming arrangements), you’re only responsible for your portion of the rent.

That’s a safer setup if you're moving in with people you don’t know well.

Always read the lease carefully before signing. If you're unsure which type you have, ask your property manager or landlord for clarification.

Housemate leaves without notice

This is where things can get sticky. In a joint lease, if someone suddenly vanishes, the unpaid rent doesn’t disappear with them.

The remaining tenants are still liable. You might end up covering their share unless you find a replacement or negotiate with the landlord, which is why it's important to pick housemates carefully.

If it’s an individual lease, the landlord deals directly with the person who left. You won’t be on the hook for their unpaid rent.

Legal action against housemate

No one wants to cover a rental dine and dasher. So, if you’ve paid more than your fair share of rent because someone else didn’t pay, you might be able to recover the money through small claims court or a tenancy tribunal.

You’ll need proof. Think bank transfers, messages agreeing on rent splits or anything in writing that shows the deal you had. It’s not always easy (or worth the stress), but it’s an option if you’re owed a decent chunk.

How to protect yourself

There are a few ways to avoid getting caught in an unpaid rent situation:

• Choose your housemates carefully: It’s not just about vibes (or even friendship). Reliability matters.
• Use written agreements: Even if it’s just a quick document between housemates, it can help sort things out later.
• Keep records of payments: Apps like RentPay are great for tracking who paid what and when.
• Set expectations early: Discuss rent due dates, payment methods and what happens if someone’s late.

These steps can save you a heap of stress later.

What landlords and agents can do

If unpaid rent becomes an issue, the landlord or property manager may issue a breach notice to all tenants on a joint lease.

If the rent stays unpaid, they could even move toward eviction.

It’s rare for things to escalate that far, but it’s a reminder that rent responsibilities are serious business.

If you're unsure about your rights, check with your local tenancy authority.

Best advice: Communicate early

If someone’s behind on rent, raise it early. A quick chat can prevent bigger issues. If it keeps happening, involve your property manager or seek advice.

Be calm, keep records, and agree on next steps as a group. Sorting unpaid rent quickly helps protect your rental and your housemate relationships.
