Form N5 is the court claim form a landlord files to start possession proceedings against a tenant. It is filed at the County Court after a valid notice (Section 8 or, for tenancies created before 1 May 2026, Section 21) has expired. This guide covers when to use it, how it fits into the possession process, and where to be careful.
What Form N5 is
Form N5 is the prescribed Civil Procedure Rules form used to start a possession claim in the County Court. It is published by HM Courts & Tribunals Service and is freely available on gov.uk:
The form is the start of the court process — not the end of it. Filing N5 produces a hearing date (and, for accelerated procedure cases under pre-RRA Section 21, a paper-track outcome). Either way, possession is not actually recovered until either the tenant leaves voluntarily or a warrant of possession is obtained and executed by County Court bailiffs.
When to use Form N5
You file N5 when a notice has expired and the tenant has not left. The notice itself depends on the tenancy and the date:
- Section 8 notice — the principal route from 1 May 2026. Used for breach of tenancy, rent arrears, anti-social behaviour, or any of the other grounds in Schedule 2 of the Housing Act 1988 as amended.
- Section 21 notice — for tenancies created before 1 May 2026, subject to the transitional provisions in the Renters' Rights Act 2025. Section 21 is no longer available for new tenancies.
- Common law notice to quit — for non-Housing Act tenancies (e.g. tenancies of agricultural land, business tenancies in some circumstances).
Filing N5 without a valid notice will result in the claim being struck out. The notice is a prerequisite, not a formality. Note also that the rent-arrears ground (Ground 8) has been amended by the Renters' Rights Act 2025 — both the arrears threshold and the notice period have been increased. Check the current text of Schedule 2 on legislation.gov.uk before serving.
N5 versus N5B: which to use
There are two related court forms. Picking the wrong one delays the claim:
- Form N5 — used for the standard possession procedure, including all Section 8 claims and most other claims. The case is allocated to a track and listed for a hearing.
- Form N5B — used only for the accelerated possession procedure under pre-RRA Section 21. The case is dealt with on the papers without a hearing in straightforward cases. From 1 May 2026, N5B's relevance falls away as Section 21 is abolished for new tenancies.
If your possession claim is on any Section 8 ground (rent arrears, breach, anti-social behaviour, mandatory grounds), you use N5 — not N5B. See our N5B page for the legacy accelerated procedure.
What to file alongside N5
The N5 form itself is the start. Most claims also need:
- A copy of the tenancy agreement — or, where the tenancy is oral, a witness statement explaining the terms.
- A copy of the notice served (Section 8, Section 21, or common law) and proof of service.
- Form N119 — Particulars of Claim (Rented Residential Premises) — the standard particulars-of-claim form used alongside N5 for rented residential possession claims. The N119 sets out the grounds, the rent arrears (if any), and the relief sought. The free form is on the gov.uk N119 page.
- Supporting evidence — rent ledgers for arrears claims, incident logs for anti-social behaviour, documentary proof of intent to occupy or sell where those grounds are pleaded.
- The court fee — current fees are published on the gov.uk court fees page and change periodically.
The supporting evidence is often what wins or loses the claim. A Section 8 ground 8 claim (mandatory rent arrears) without a clean rent ledger covering the arrears period will struggle, even if the arrears are real.
The procedure after filing
Once N5 is issued by the court:
- The court serves the claim on the tenant.
- The tenant has a fixed period to respond using Form N9 (acknowledgment of service / defence).
- The court allocates the case to a track and lists it for a hearing.
- At the hearing, the judge considers the evidence and either makes a possession order or dismisses the claim.
- If a possession order is made and the tenant doesn't leave by the date specified, the landlord applies for a warrant of possession (Form N325) and the County Court bailiffs execute it.
The whole process from notice service to bailiff eviction typically takes several months and rarely fewer than three. Plan accordingly.
Common mistakes that defeat possession claims
Patterns from possession case outcomes suggest several recurring errors that defeat otherwise valid claims.
Defective notice. The most common reason possession claims fail. The notice (Section 8 or Section 21) must be on the prescribed form, contain the correct content, and have expired before the N5 is filed. Even small defects — wrong notice period, missing ground, served on the wrong person — can be fatal.
No proof of service. The court needs to be able to see that the notice was actually given to the tenant. Recorded delivery, witnessed hand-delivery, or email service (where the tenancy permits it) all produce proof. A claim without proof of service often fails on technical grounds.
Missing prerequisites for Section 21. Pre-RRA Section 21 claims require deposit protection, prescribed information, EPC, gas safety, and How to Rent guide. Any prerequisite missed makes the Section 21 invalid and the N5 claim doomed. From 1 May 2026 this becomes academic for new tenancies, but legacy Section 21 claims still need every prerequisite documented.
Inadequate evidence for the ground pleaded. Ground 8 needs the rent ledger. Ground 14 (anti-social behaviour) needs an incident log, ideally with police references. Ground 1 (landlord's own occupation) needs documentary proof of intent to occupy. Pleading a ground without backing evidence often results in the judge declining to grant possession on that ground.
Filing while in dispute with deposit protection scheme. Outstanding adjudication or deposit-related disputes can complicate the claim. Resolve deposit issues separately, or accept that they may be raised by the tenant as a defence.
When to get proper legal advice
Possession proceedings are legally complex and the consequences of getting it wrong are significant — both financial (court fees, lost rent) and procedural (having to start the notice period over). You should consider a practising solicitor or specialist possession service if any of the following apply:
- The tenant has indicated they will defend the claim or raise a counterclaim.
- You are pleading a discretionary ground (10, 11, 12, 13, 14) where the judge has discretion to refuse possession.
- The tenant claims to have a counterclaim for disrepair, harassment, or unlawful eviction.
- The deposit was not protected, the prescribed information was not served, or there are gas safety / EPC / How to Rent issues.
- You are pleading anti-social behaviour and need supporting evidence assembled and presented.
- The tenancy has unusual features (resident landlord, rent above £100,000, company tenant, mixed-use property).

Common questions
Can I fill in Form N5 myself?
Yes, in principle. Many landlords do, and the form is designed to be filled in without legal training. However, possession claims are legally serious, and an unsuccessful claim can often only be re-tried after starting the notice period afresh — costing months. For any non-standard situation (disputed tenancy, mandatory grounds with weak evidence, tenant on benefits with rent paid via universal credit, anti-social behaviour cases), instructing a solicitor or paid possession service is usually worth the cost.
Where do I file the N5?
Possession claims are filed at the local County Court Hearing Centre serving the property's address. Many possession claims can also be issued online through Possession Claim Online (PCOL), HM Courts & Tribunals Service's online filing system for accelerated and standard possession claims meeting the eligibility criteria. The current filing routes and PCOL eligibility are explained on the gov.uk Form N5 page linked above and in the accompanying notes.
How long does the possession process take?
The process from notice service through to bailiff eviction typically takes several months and is rarely faster than three. Court backlogs vary by location and time of year. Notice period itself, plus the court hearing wait, plus the period between possession order and warrant execution, all add time.
What's the difference between N5 and N5B?
N5 is the standard possession claim form used for all Section 8 claims and most other possession actions. N5B is the accelerated procedure form used only for pre-RRA Section 21 claims, decided on paper without a hearing. From 1 May 2026, N5B's relevance is largely confined to legacy Section 21 claims under the transitional provisions.
Do I need a solicitor for a possession claim?
For a straightforward Ground 8 rent-arrears claim with a clean ledger and properly served notice, many landlords represent themselves successfully. For anything involving discretionary grounds, anti-social behaviour, deposit complications, or where the tenant has indicated they will defend, instructing a practising solicitor specialising in landlord and tenant law is strongly advised. The cost of a defective claim is often more than the cost of professional advice.
What happens if the tenant leaves before the hearing?
If the tenant leaves voluntarily before the hearing, you should write to the court withdrawing the claim. You may still pursue any rent arrears separately as a money claim. If you have already paid the court fee, recovery of the fee is at the court's discretion.
