What to do when a roommate won’t pay their share
The order to do things in, what to put in writing, and when it stops being a conversation.
In this guide
Work through it in order: confirm the amount in writing, ask once, plainly, with a date, then offer a payment plan if they cannot pay rather than will not. If rent to the landlord is at risk, raise it with the landlord or agent early — on a joint tenancy the arrears are usually the whole household’s problem, not just theirs. Escalate to formal steps only once the written record shows a clear ask and a clear refusal.
- Separate "cannot pay" from "will not pay" before you decide anything. They need completely different responses.
- Move everything into writing early. A dated message thread is what every later step depends on.
- On a joint tenancy the landlord can usually pursue any tenant for the full rent, so unpaid rent is an emergency for the household, not just for the person who missed it.
- Never let the shortfall become an informal loan from one housemate. Whoever covers it should be recorded as owed, in writing, that day.
- Check your local tenancy service before threatening any formal step — the rules differ significantly by country and by state.
There is a version of this problem that resolves in a day and a version that ends a tenancy, and the difference is usually how the first two conversations went. The goal early on is not to win — it is to establish, on the record and without accusation, what is owed and when it will arrive.
First: establish what is actually owed
Before any conversation, be able to state the number and where it came from. "You owe about three hundred, I think" invites a negotiation about the amount instead of a conversation about payment.
- The exact figure, itemised — rent for which month, which bills, at what split.
- The agreed split it was calculated from. If your household never wrote one down, start with the four standard methods and agree one now.
- Who covered the shortfall, if anyone, and on what date.
- The due date that was missed.
The escalation ladder
- Send the number in writing. One short message: the amount, what it covers, the date it was due, and how to pay. No commentary. This is the message every later step refers back to.
- Ask directly, once, with a date. "Can you send the $340 for July rent by Friday?" A specific date turns an open obligation into a commitment you can follow up on without accusing anyone.
- Find out whether they can pay. If they cannot, a payment plan collects more money than pressure does. Agree instalments and amounts in writing. If they will not, stop negotiating and move down the ladder.
- Tell the landlord or agent early if rent is short. Households often hide arrears hoping to fix them quietly. That usually makes it worse: on a joint tenancy the landlord can pursue any tenant for the full amount, and a household that flagged the problem early is in a far better position than one that was found out.
- Get advice before any formal step. Contact your local tenancy or housing advice service. What you can do about a non-paying co-tenant — and what you must not do, such as changing locks or removing belongings — depends entirely on where you live and how the tenancy is written.
Who covers the gap in the meantime
Somebody usually has to, because the landlord and the utility company do not care about your internal arrangement. The important thing is that covering it is recorded as a debt on the day it happens, not absorbed silently.
| Situation | What to do | Why |
|---|---|---|
| One housemate covers the whole shortfall | Record it as a debt from the non-payer to that person, with the date and amount, in the household record. | Otherwise it becomes an undocumented loan that is impossible to settle at move-out. |
| The household splits the shortfall | Record each person’s contribution separately, not as a lump. | Each contributor is individually owed, and at move-out they need their own figure. |
| Nobody covers it and rent goes short | Tell the landlord or agent immediately and get advice the same week. | Arrears on a joint tenancy expose everyone, including people who paid in full. |
| It is a bill in one person’s name | That person should not let it default while the dispute runs. | The account holder carries the credit consequences alone, whatever the household agreed. |
If they are moving out owing money
This is where an undocumented household loses the money. Two things to do before they hand back keys:
- Settle the balance separately from the deposit. The deposit is held by the landlord against damage, not against your internal debts, and it is usually released long after they have gone. Our guide on tracking deposit contributions covers how to keep the two apart.
- Get the outstanding amount and a date in writing before the handover, while there is still something they want from you — a reference, a deposit share, a smooth exit.
Households do not lose money because someone refused to pay. They lose it because nobody wrote down what was owed while it was still a small number.
Making it not happen again
Almost every case of this starts the same way: an informal arrangement, a single payer fronting everything, and no record. Three habits remove most of the risk.
- Write the split down at move-in, including who pays which account and on what date.
- Spread the accounts so no single person is fronting rent and every bill.
- Keep a shared record everyone can see. When the balance is visible to the whole household, nobody has to be the person who brings it up — which is the reason most shortfalls go unmentioned until they are large.
