Form N215: Certificate of Service

Form N215 is the certificate of service — the court form used to record how, when, where and on whom a document was served, so the court can rely on that service later in the case. In residential possession proceedings it most commonly certifies service of the Section 8 notice that must precede a claim, and, where the landlord (rather than the court) serves the claim form itself, service of Form N5. Service is the most procedurally vulnerable stage of any possession claim: if service of the underlying notice or claim form cannot be proven, the case stalls for fresh service. This page explains what Form N215 is, when it is needed, how the Civil Procedure Rules' deemed-service dates work, section-by-section completion, and what typically goes wrong.

What Form N215 is

Form N215 is the prescribed certificate of service used in civil proceedings, including residential possession claims, to record which document was served, on whom, and when, where and how. It is published by HM Courts & Tribunals Service and available on gov.uk.

Certificates of service exist because Civil Procedure Rules Part 6 does not simply require service to have happened — it requires the court to be able to establish, from a documented record, that it happened by a method the rules permit, and to fix the deemed date on which service is treated as complete. That deemed date matters: it is what the notice period and the tenant's response deadlines run from, not the date the document was actually read.

In residential possession proceedings, Form N215 is most commonly used to certify:

• Service of the Section 8 notice, before the possession claim is issued.
• Service of the claim form (Form N5) and particulars (Form N119), where the claimant — rather than the court — has served them.
• Service of Form 6A Section 21 notices, for tenancies still running under the transitional pre-1-May-2026 rules.
• Other court documents or orders during proceedings where the claimant has served rather than the court.

When Form N215 is required — and when it isn't

Certifying service of the pre-action notice

Before a landlord can issue a possession claim, the appropriate statutory notice must have been validly served and, in most cases, have expired. From 1 May 2026 that is a Section 8 notice specifying one or more grounds in Schedule 2 to the Housing Act 1988 (as amended by the Renters' Rights Act 2025); for tenancies still governed by transitional provisions, it may be a Section 21 notice (Form 6A) served before that date.

There is no statutory requirement to file an N215 for the notice at the point the notice is served — it isn't a court document yet. But when the possession claim (Form N5 and Form N119) is later filed, the tenant can and often does dispute that the notice was ever received. A landlord who completed Form N215 at the time of service, and kept it with dated evidence (proof of postage, photographs, a witness statement from whoever delivered it), is in a far stronger position than one relying on recollection months later. Treat the certificate as something you complete contemporaneously and hold on file, ready to be exhibited to your witness statement if service is challenged.

Certifying service of the claim form

Under CPR 6.17, where the court serves the claim form, the court itself sends the claimant a notice confirming the deemed date of service under CPR 6.14 — no action is needed from the landlord. But where the claimant serves the claim form directly (because the court has directed it, or the tenant's service address needs the claimant's own arrangements), CPR 6.17(2) requires the claimant to file a certificate of service within 21 days of service of the particulars of claim — unless every defendant has already filed an acknowledgment of service within that time. Critically, CPR 6.17(2)(b) provides that the claimant cannot obtain default judgment unless a certificate of service has been filed. Missing this step doesn't just cause administrative delay — it removes an enforcement route entirely until put right.

Certifying service of other documents during proceedings

CPR 6.29 requires that, wherever a rule, practice direction or court order calls for a certificate of service of a document other than the claim form, the certificate states the specific details set out in the CPR 6.29 table (method, and the relevant date and, for personal service, time). Form N215 is the standard vehicle for this.

What the Civil Procedure Rules say about deemed service

This is the part landlords most often get wrong, because the "deemed" date is not necessarily the date the document actually arrived — it is a fixed rule.

Claim forms (CPR 6.14). A claim form served within the United Kingdom is deemed served on the second business day after the relevant step for service is completed — regardless of the method used.

Every other document, including notices (CPR 6.26). The deemed date depends on the method:

• First-class post (or another next-business-day service): the second day after posting, provided that day is a business day; if not, the next business day after that.
• Delivering to, or leaving at, a permitted address: the same day if delivered before 4.30pm on a business day; otherwise the next business day.
• Personal service: the same day if served before 4.30pm on a business day; otherwise the next business day.
• Document exchange, fax, or other electronic method: broadly the same "before 4.30pm on a business day" logic.

A "business day" excludes Saturdays, Sundays, bank holidays, Good Friday and Christmas Day. Landlords calculating a Section 8 notice period, or working out whether a claim was issued too early, need to run the calculation from the correct deemed date under CPR 6.26 — not the date of posting itself.

Section-by-section completion

1. Court and case details

Court name and, if proceedings are already issued, the claim number and the names of claimant and defendant. Where the certificate is completed to evidence service of a pre-action notice (before any claim exists), the claim number is left blank.

2. The document served

State exactly what was served — for example, "Section 8 notice under section 8 of the Housing Act 1988 (as amended) seeking possession of [address], dated [date], relying on Ground(s) [x]". Vague descriptions ("a notice") undermine the certificate's evidential value.

3. Person served

Full name and address of the recipient. Where the tenancy is in joint names, each tenant needs their own record of service — serve, and be prepared to prove service on, every named tenant.

4. Method of service

Select and describe the method used, matching one of the categories in the CPR 6.26 table above (personal service, first-class post, leaving at the property, electronic service where the tenancy permits it, and so on).

5. Date (and, where relevant, time) of service

The date the step was actually taken — the date posted, the date and time handed over personally, or the date left at the property — not the deemed date. The court applies the CPR deeming rules to whatever date you certify.

6. Statement of truth

Signed by the person who actually carried out the service — the landlord, an agent, or a process server. Signing a statement of truth you know to be false is a contempt of court matter; only sign for service you personally carried out or directly witnessed.

Best practice in serving notices and claim forms

• Use more than one method. First-class post with proof of postage, combined with personal delivery or leaving a copy at the property (photographed, dated), is stronger than either alone.
• Photograph what you can. A dated, address-verifiable photograph of a notice being posted through a letterbox or handed over is strong contemporaneous evidence.
• Be cautious with recorded or signed-for delivery. If the tenant declines to sign, the item can be returned undelivered — which can undermine, rather than support, your case. First-class post with a certificate of posting is usually more reliable for residential service.
• Don't rely on email alone, even where the tenancy permits electronic service — treat it as a backup to a physical method.
• Complete the N215 at the time, not retrospectively. A certificate written up weeks later, from memory, carries far less weight if challenged.

What can go wrong

The tenant disputes service. The single most common challenge — the tenant says the notice or claim form was never received. Without a contemporaneous, specific certificate and supporting evidence, this becomes a credibility dispute the landlord may not win.

Wrong address or wrong method. Service at an address the tenant no longer occupies, or by a method the tenancy doesn't permit (e.g., email where there's no agreement to accept service that way), is defective.

Not all joint tenants served. Where a tenancy is in joint names, every named tenant must be served and the certificate should reflect that.

Certificate not filed where required. Under CPR 6.17(2), failing to file a certificate of service of the claim form (where the claimant served it) blocks default judgment until the certificate is filed — an avoidable delay.

Getting the deemed-service date wrong. Confusing the actual date of service with the CPR-deemed date (and the CPR 6.14 rule for claim forms against the CPR 6.26 table for everything else) can lead to a notice period, or a response deadline, being calculated incorrectly.

A note on legal advice

This page explains how Form N215 and the CPR Part 6 service rules work in general terms; it is not legal advice on your specific case. Service disputes and default judgment applications can turn on fine factual and procedural detail, and the consequences of getting it wrong — an adjourned or struck-out claim — are costly in time and court fees. Where service is contested, or a claim is high-value or urgent, take independent advice from a practising solicitor.
