What to Do When a Housemate Will Not Pay Rent

A housemate missing rent is the single most stressful thing that happens in a share house, partly because of the money and partly because you still have to share a kitchen with them.

Work through it in stages. Most situations resolve at stage one.

First, work out what your exposure actually is

This determines everything, so establish it before you do anything else.

If you are all on one lease together, you are almost certainly jointly and severally liable. In plain terms, the landlord can pursue any one of you for the entire rent, not just your share. If your housemate does not pay, the shortfall is legally your problem too, and it is your name on the arrears.

If you each have a separate agreement with the landlord or head tenant, your liability usually stops at your own share.

If you are subletting from a head tenant, your agreement is with them, and their agreement is with the landlord.

Tenancy law differs by state and territory in Australia, and the details matter. Check with the authority where you live: Fair Trading in NSW, Consumer Affairs in Victoria, the RTA in Queensland, and the equivalent body elsewhere. Most offer free advice to renters.

Stage one: ask directly and privately

Not in the group chat. One conversation, in person, without an audience.

People fall behind for reasons that are usually temporary and often embarrassing: shifts cut, a surprise bill, a card cancelled, a relationship ending. A housemate who is avoiding the group chat is frequently ashamed rather than unwilling.

Ask two things. When can you pay, and how much. Then get a specific date, not “soon”.

Stage two: put the agreement in writing

If they need time, that is often reasonable. Make it concrete.

Write down the amount owed, the date it will be paid, and whether it is coming in one payment or instalments. A message they reply “yes” to is enough. You are not being cold, you are removing the ambiguity that turns a late payment into a dispute.

Keep the record. If this escalates later, a clear timeline of what was agreed and when is the most useful thing you can have.

Stage three: protect the rest of the house

If the rent is due to the landlord and one person is short, the rest of you generally need to cover it to avoid the whole tenancy going into arrears. That feels deeply unfair, and it is, but a breach notice affects everyone’s rental history, not just theirs.

Cover it, record exactly who paid what, and treat the shortfall as a debt owed to the housemates who covered it rather than to the landlord.

This is where accurate records stop being administrative and start being genuinely important. In Mates on Rent, unpaid months roll into an arrears summary per person showing how many months and how much, so there is never an argument about the number.

Stage four: formal steps

If it has gone on for weeks with no realistic plan, your options depend on the lease structure.

• Co tenants on one lease: you generally cannot evict each other. What you can usually do is apply to your state tribunal to have their name removed from the tenancy, or negotiate with the landlord to replace them.
• They sublet from you as head tenant: you have obligations as their landlord, including proper notice periods. Do not change locks or remove belongings. That can put you in the wrong very quickly, regardless of what they owe.
• Separate agreements: it is between them and the landlord, though you may want to prompt the landlord to act.

Get advice from your state authority before taking any formal step. Free tenant advice services exist in every state, and using one is much cheaper than getting it wrong.

What not to do

Do not change the locks. In almost every Australian jurisdiction this is unlawful, and it converts your strong position into a weak one instantly.

Do not remove their belongings. Same reasoning.

Do not let it run silently for months. The most common version of this problem is not a housemate who refuses to pay, it is a house that felt too awkward to raise it until the debt was four figures. Raise it in week one.

Preventing the next one

Agree the due day up front, and make it a few days after payday rather than the first of the month.

Keep a visible shared record. Most rent disputes in share houses are genuine confusion rather than bad faith. When there is one record everyone can see, the confusion disappears and the actual problems surface early, while they are still small.

Have the awkward conversation early. Ask a prospective housemate how they will handle rent if their hours get cut. Their answer tells you a lot.

Consider a house buffer. Some share houses keep one or two weeks of rent in a shared account so a single bad month does not become an emergency.

None of this makes the conversation comfortable. It does make it shorter.
