The New Notice of Termination Rules (March 2026): Serve It Right or Lose at the RTB

A notice of termination is the single highest-stakes document in lettings. Everything else — a late rent reminder, a maintenance note — can be fixed after the fact. A defective notice of termination can't: it's found invalid at the RTB months later, the tenancy continues, and you begin the whole process again from day one. In a market where a landlord may be trying to sell or move back in, that delay is measured in tens of thousands of euro.

The March 2026 reforms didn't make ending a tenancy impossible. They made it unforgiving of paperwork. The rules now assume the RTB sees the notice the day it's served, and they leave no room for a period that's a few days short or a reason left blank.

What changed on 1 March 2026

Two changes matter most for anyone serving a notice of termination today:

• Same-day RTB filing. A copy of the notice of termination must be provided to the Residential Tenancies Board on the same day it is served on the tenant. The RTB no longer learns about a termination weeks later — it has the notice in hand from day one, which means a late or missing filing is visible immediately.
• The reason must be stated. The notice has to set out the ground for termination. A no-fault ground (selling, own use, refurbishment) generally also requires a supporting statutory declaration or statement. A notice that doesn't say why is defective on its face.

These sit on top of the rules that were already strict: the notice period has to match the tenancy's length, the termination date has to be right, and service has to be done in a permitted way. What the reform did was remove the slack — with the RTB copied on the same day, there's nowhere for a paperwork gap to hide.

The four ways a notice of termination fails

Almost every invalid notice comes down to one of four failures. Name them and you can design each one out.

Notice that none of these is about knowing that you can end the tenancy. They're all about the mechanics — the period, the reason, the filing, the service. That's precisely the part that should be computed from the tenancy record, not assembled by hand under time pressure.

Notice periods by tenancy length

The single most common technical error is the notice period. It isn't one number — it scales with how long the tenancy has lasted. The longer someone has lived in the property, the more notice they're owed. The table below shows the shape of the sliding scale; treat the exact figures as illustrative and confirm the current period for your tenancy at rtb.ie.

A shorter period can apply where the tenant is in serious breach (for example, non-payment of rent after a valid warning, or anti-social behaviour), but those grounds carry their own procedural steps — a rent-arrears warning notice and a chance to remedy — that are just as easy to get wrong. The safe assumption is that the standard sliding scale applies unless you've confirmed otherwise.

The notice period is arithmetic on the tenancy start date. A human doing that arithmetic across a portfolio, under pressure, will eventually be a few days out — and a few days out is the whole notice.

Valid grounds for termination

During a Tenancy of Minimum Duration you can't end a tenancy simply because you'd prefer to. You need a ground the Acts recognise, and for no-fault grounds you need to back it with the required declaration. The common grounds are:

• Intention to sell. A genuine intention to sell the property, subject to conditions (see below).
• Own or family use. The landlord, or a specified family member, requires the property to live in.
• Substantial refurbishment. Works that require the property to be vacant — again with evidence and, typically, an offer back to the tenant afterwards.
• Change of use. The property is to be used for a purpose other than as a dwelling.
• Tenant breach. Non-payment of rent (after a valid warning), anti-social behaviour, or another serious breach of tenant obligations.

The "intention to sell" ground, done properly

Because most notices cite an intention to sell, it's the ground the RTB looks at hardest. Used correctly it's entirely legitimate; used loosely it's the fastest route to an overturned eviction. In practice, a defensible intention-to-sell notice needs:

• A genuine, evidenced intention to sell — not a placeholder reason to recover vacant possession.
• The required statutory declaration of that intention, in the correct form, served with the notice.
• An understanding of the offer-back obligation — if the sale doesn't proceed within the set period, the property may have to be offered back to the former tenant.
• The correct notice period for the tenancy length, and same-day RTB filing, like any other notice.

The reforms since March 2026 also tightened when no-fault grounds can be relied on during a tenancy's minimum-duration cycle. The consequence for landlords who genuinely intend to sell is simple: the ground is fine, but the paperwork and timing around it are unforgiving — so it has to be right first time.

Why a template off Google gets an eviction overturned

A generic notice-of-termination template is the most expensive free download in lettings. It fails for reasons that are invisible until an adjudicator points them out:

• It hard-codes a single notice period. A template can't know your tenancy started three years ago, so it can't give the right number of days — and the right number is the whole point.
• It doesn't include the declaration. The statutory declaration for a no-fault ground is a separate, specific document a template rarely provides.
• It doesn't file with the RTB. A downloaded Word file has no way to produce and lodge the same-day RTB copy the reforms require.
• It has no dates to track. Once served, nothing watches the termination date — so the tenancy is sometimes ended before the period has fully run, which is its own invalidity.

The template isn't wrong because it's badly written. It's wrong because a static document can't do the one thing a valid notice requires: reflect this tenancy's length, ground and dates, and reach the RTB the same day.

The notice of termination checklist

Whether you generate it in an app or prepare it by hand, this is the standing list to tick for every notice of termination.

How TenantSync serves it right

TenantSync is built so the mechanics of a notice of termination can't depend on memory or a downloaded template. It generates the notice from the data you already hold and watches the dates that follow:

• Notice period calculated automatically. The tenancy's start date and length are already in the record, so the required notice period — and the correct termination date — are derived for you, not typed in.
• Statutory reason built in. The notice is generated with the ground stated, and prompts for the declaration a no-fault ground needs — so a notice never goes out with the reason left blank.
• RTB copy for same-day filing. TenantSync produces the RTB copy alongside the tenant's notice, so both are ready to go out the same day the reform requires.
• Served and expiry dates on the dashboard. Once served, the termination date is tracked on the same compliance dashboard as registration and rent-review deadlines — so the tenancy is only ended when the period has fully run, and nothing is lost in a diary.

It's the same engine that keeps every RTB registration and renewal on track and checks rent reviews against the national rent cap — one platform, on web, iOS and Android, so the highest-stakes document in lettings stops being the one you serve nervously.

How to get started

1. Start your free 14-day trial — no credit card required.
2. Add the tenancy with its start date — the notice period calculates itself.
3. Generate the notice of termination with the ground and the RTB copy.
4. Serve and file the same day, and let the dashboard track the termination date.
