Quick answer: When rent stops arriving, the sensible sequence is to reach out promptly and in writing, escalate to a formal letter of demand if the conversation does not resolve it, consider deducting documented arrears from the security deposit, and use the Small Claims Tribunal for straightforward monetary recovery if the amount owed sits within its limit. If the tenant will not pay and will not leave, that is when the formal eviction process, built on proper notice and a court order, becomes necessary. The single biggest mistake landlords make is waiting too long to act on the first missed payment, hoping it resolves itself.

Rent arrears rarely start as a crisis. Usually it is a single late payment, a text saying it will be in by the weekend, then a second late payment, then silence. How you respond to that very first sign shapes everything that follows, and most landlords either overreact too early or, more often, wait far too long hoping the problem resolves itself. Neither serves you well.

The first conversation: before anything gets formal

The moment a payment is late, reach out directly, calmly and in writing. A short message noting the missed payment and asking for an update does two things at once: it gives the tenant a fair chance to explain a genuine hiccup, and it starts a documented timeline that matters enormously if this escalates later. Most arrears situations are resolved at exactly this stage, a tenant catching up after a delayed salary, an administrative mix up with a bank transfer, or a temporary cash flow issue they are upfront about.

What you are watching for is the pattern, not the single incident. One late payment with a clear explanation and prompt catch up is normal tenancy friction. A second late payment, a vague or absent response, or an amount that keeps growing is the signal to move from a casual conversation to a documented process.

Sending a formal letter of demand

If the informal conversation does not resolve the arrears within a reasonable window, the next step is a formal letter of demand. This sets out the exact amount owed, the period it covers, and a clear deadline to pay, and it puts the tenant on notice that you are treating this seriously and are prepared to escalate if it is ignored. Keep the tone factual rather than emotional, the letter is a legal document as much as a communication, and its value later depends on being precise and professional.

This is also the point where many landlords choose to reference their tenancy agreement's specific default clause, if one exists, since referencing the exact contractual breach strengthens your position if the matter proceeds further. My tenancy agreement clauses guide covers what a well drafted default clause should include, which matters more once you are actually relying on it.

Deducting from the security deposit

A security deposit exists precisely for situations like this, and deducting documented arrears from it is a reasonable and common step. The practical limit is obvious, the deposit only covers arrears up to the amount held, and most deposits are not large enough to absorb more than a month or two of unpaid rent before you are back to being genuinely out of pocket. Document the shortfall clearly and communicate the deduction to the tenant in writing, since disputes over deposit deductions are themselves a common source of friction.

Using the Small Claims Tribunal

For straightforward claims to recover unpaid rent that fall within its jurisdiction limit, the Small Claims Tribunal offers a genuinely useful, lower cost and faster route than full civil litigation. It is designed for exactly this kind of dispute, a documented sum owed under a contract, and landlords with a clean paper trail, rent ledger, tenancy agreement, correspondence, tend to do well there without needing extensive legal representation.

What the tribunal does not do is recover physical possession of the unit if the tenant also refuses to leave. It addresses the money owed, not the occupancy itself. If arrears have escalated to the point where the tenant is both unpaying and unwilling to vacate, you are looking at two separate tracks, recovering the debt and separately pursuing possession through the courts.

When arrears tip into an eviction case

Non payment of rent is a clear breach of most tenancy agreements, and once your formal notice period has passed without the tenant remedying the arrears or vacating, you are generally in a position to begin the formal process for possession if they still will not leave. This is a heavier step than recovering the money owed, and it follows the same court driven process, proper notice, a court application, and ultimately a writ of possession executed by the sheriff if it comes to that.

My separate guide on the legal eviction process walks through that path in full detail, including why changing the locks or otherwise acting unilaterally is not a shortcut available to landlords, however justified it might feel in the moment.

Protecting yourself before this ever happens

The landlords who deal with arrears most calmly are almost always the ones who screened properly before signing the lease. Employment verification, references from a previous landlord, and a deposit that genuinely reflects the risk profile of the tenant all reduce how often this situation arises in the first place. My guide to screening tenants covers the practical checks worth doing, and they take far less time than a single month of chasing unpaid rent.

It is also worth reviewing your wider rental setup, since a single problem tenancy affects your overall cash flow differently depending on how leveraged your portfolio is. My complete landlord guide covers that broader operational picture.

A realistic timeline for the whole escalation

1. Week one: informal written outreach the moment payment is late, giving the tenant room to explain and catch up.
2. Week two to three: formal letter of demand if the conversation has not resolved the arrears, with a clear deadline.
3. After the deadline: deposit deduction for documented arrears, and consider whether the Small Claims Tribunal is appropriate for recovering the remaining amount.
4. If the tenant will not vacate and arrears continue: formal notice under the eviction process, followed by court application if the tenant still remains after the notice period.

This is not a fast sequence, and it is not meant to be, each step exists to protect your legal position at the next one. Landlords who skip steps, or who wait months before sending even the first written message, generally end up worse off than those who act promptly and methodically from the very first missed payment.

Frequently asked questions

What should I do first if a tenant stops paying rent?

Reach out directly and in writing as soon as a payment is late, before assuming the worst. A short, factual message noting the missed payment and asking for an update often surfaces the real issue, whether it is a genuine cash flow problem, an administrative slip, or a sign of a bigger dispute, and it starts your documentation trail from the earliest possible point.

Can I just keep the security deposit if rent is unpaid?

You can deduct legitimate arrears from the security deposit, but only up to the deposit amount held and generally only after documenting the shortfall clearly, since the deposit is meant to cover exactly this kind of default. It is rarely enough to cover a prolonged non payment situation on its own, and using it does not resolve months of ongoing unpaid rent beyond what the deposit covers.

Is the Small Claims Tribunal useful for rent arrears?

Yes, for straightforward monetary claims within its jurisdiction limit, the Small Claims Tribunal offers a faster and cheaper route than full civil litigation to recover unpaid rent. It handles the money owed, however, not the physical recovery of the unit if the tenant also needs to be evicted, which requires the separate court process for a writ of possession.

When does non payment become grounds for eviction?

Non payment of rent is typically a clear breach of the tenancy agreement, and once you have issued formal notice giving the tenant a chance to remedy the arrears or vacate, and that notice period has passed without resolution, you are generally in a position to begin the formal eviction process through the courts if the tenant still will not leave voluntarily.

How can I reduce the risk of rent arrears in future?

Screen tenants properly before signing, including employment verification and references, set a deposit that reflects genuine risk, and act on the very first late payment rather than letting a pattern establish itself. Landlords who address the first missed payment promptly and firmly tend to see far fewer arrears situations escalate into prolonged disputes.
