Form N215 Certificate of Service UK: How to File
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
When you serve documents in a civil claim in England and Wales, the court often needs written confirmation that service actually happened. That is what Form N215, the Certificate of Service, is for. It records who sent what, to whom, by which method, and on what date, so the court and the other side have a clear audit trail.
Getting this form right matters more than people think. If the certificate is incomplete or the method of service does not match the rules, any deadlines that flow from service (such as the time for filing a defence) can be thrown into doubt.
In this guide I'll walk through what the form is, what to put on it, how the deemed service rules work under Part 6 of the Civil Procedure Rules, and the practical traps I see people fall into most often.
What this document is
Form N215 is the standard court form used in civil proceedings to certify that a document has been served on another party. It is not the act of service itself, it is the written proof that service took place. Once completed, it is filed with the court so there is a record of how and when the other side received the relevant papers.
The form is used across a wide range of civil matters, from money claims and possession proceedings to applications made during ongoing litigation. Common documents that require a certificate of service include the claim form itself, particulars of claim, witness statements, and application notices.
The rules on what must be served, how it must be served, and within what time limits sit in Part 6 of the Civil Procedure Rules, and N215 is designed to capture the key facts those rules care about: the method used, the address served at, and the date the document was sent or delivered.
How to use this document
- Identify the case details. Start by filling in the court name, the claim number, and the full names of the claimant and defendant exactly as they appear on the original claim form. Even small discrepancies in spelling or party order can cause the court office to reject the filing or associate it with the wrong file, so check these against your existing paperwork. 2. Record what you served and when. List every document that was served in this particular act of service, for example the claim form, particulars of claim, or a specific application notice. Enter the exact date on which service took place. If the documents have not already been filed at court, attach copies so the court has a complete record alongside the certificate. 3. Specify the method of service. Tick or state the method used, whether that was first class post, personal delivery, document exchange, fax, email, or leaving the papers at a permitted address. The method has to be one that is allowed under Part 6 CPR for that document and recipient, and for electronic methods the recipient must generally have indicated they accept service that way. 4. Enter the address or contact details used. Write in the full address, DX number, fax number, or email address to which the document was sent or at which it was left. This detail is what links your method of service to the rules on where a party can validly be served, so be precise rather than approximate, and keep any delivery receipts or sent-email records on file. 5. Sign, date and file the certificate. The form must be signed by the party serving the document, their solicitor, or their litigation friend, and dated. File the completed N215 at the court handling the claim, either on paper or through the relevant electronic filing route. If filing electronically, keep the submission confirmation so you can prove the date of filing if it is ever questioned.

Common questions
Q When do I actually need to file Form N215?
You generally need to file a certificate of service when you (rather than the court) have served a document and the rules or a court order require proof of service. The classic example is when a claimant serves the claim form themselves. It is also common after serving application notices or orders. If the court served the document for you, you usually do not need to file N215.
Q What counts as the deemed date of service?
Under Part 6 of the Civil Procedure Rules, a claim form served within the UK is generally deemed served on the second business day after the claimant has completed the required step, such as posting it or sending it by a permitted electronic method. Other documents have their own deemed service rules depending on the method used, so always check the table in CPR Part 6 for the specific document and method.
Q Can I serve documents by email?
Email service is possible, but only where the receiving party or their solicitor has confirmed in writing that they will accept service by email, and only at the address they have nominated. You should also check whether they have specified any format or size restrictions. If those conditions are not met, email service can be challenged, which in turn undermines any N215 that relies on it.
Q What happens if the certificate of service is wrong?
Errors on an N215 can have real consequences. If the date, method, or address is inaccurate, the other side may argue service was not valid, which can affect deadlines for filing a defence or acknowledgment of service. In some cases the court can put things right, but you may need to apply for relief. It is far safer to get the detail correct first time.
Q Who can sign the Certificate of Service?
The form can be signed by the party who served the document, their solicitor, or a litigation friend where one is acting. If a solicitor or firm is on the record, it is usually signed on their letterhead or in their name. The signatory is confirming the truth of the information on the form, so they should have personal knowledge of how and when service took place.
Q Is there a deadline for filing N215 after service?
Yes, and it depends on the document. For a claim form served by the claimant, the certificate of service generally needs to be filed within a short window after service. Other documents have their own timing rules. Because the deadlines are document-specific, check the relevant CPR provision for the document you served rather than assuming a single universal limit applies.
Q Can I file Form N215 electronically?
In many courts, yes. Electronic filing is available through the relevant court portal for a range of civil claims. If you file electronically, keep the submission receipt or transmission record, as that is your evidence of when the certificate reached the court. If you file on paper, consider using a method that provides proof of delivery to the court office.
