Serving a County Court Claim: Form N215, Deemed Service Dates and Proof of Service
Your claim can be perfectly drafted and your evidence watertight — but if you do not serve it properly, the court cannot enforce it. Service is the formal act of delivering court documents to the other side, and CPR Part 6 sets strict rules about how, when and where you can do it.
Who serves the claim form
When you issue a claim through the Online Civil Money Claims (OCMC) portal, HMCTS serves the claim form on the defendant by first-class post automatically. You do not need to do anything extra.
If you file a paper form N1 through the Civil National Business Centre, the court serves the claim form by first-class post to the defendant's address unless you specifically tell the court that you want to serve it yourself. Reasons for personal service include wanting to use a process server for a defendant who is hard to reach or wanting to serve at a specific address not listed on the claim form.
Methods of service under CPR Part 6
CPR 6.20 allows these methods for documents other than the claim form (e.g. witness statements, evidence bundles, applications):
- First-class post or document exchange — post it to the defendant's last known address or registered office
- Personal service — hand the document directly to the individual, or leave it at a company's registered office
- Fax — only if the other party has given a fax number for service
- Email or other electronic means — only with the other party's prior written consent
- Leaving at an address — posting through the letterbox at the defendant's address for service
For a company, CPR 6.9 allows service at its registered office or at a place of business in the jurisdiction that has a real connection with the claim.
Deemed service dates
Service is not complete the moment you post the letter. Under CPR 6.14, a claim form served within the UK is deemed served on the second business day after the relevant service step is completed. For documents other than claim forms, CPR 6.26 sets the dates below:
| Method | Deemed date of service |
|---|---|
| First-class post | The second day after posting if it is a business day; otherwise the next business day |
| Personal service | The same day if served before 4:30 pm on a business day; otherwise the next business day |
| Document exchange | The second day after leaving at the exchange if it is a business day; otherwise the next business day |
| Fax | The same business day if sent before 4:30 pm; otherwise the next business day |
| Email or other electronic | The same business day if sent before 4:30 pm; otherwise the next business day |
Business days exclude Saturdays, Sundays, bank holidays, Good Friday and Christmas Day. If you post a document on a Thursday, the deemed date is the following Monday — and the defendant's time to respond runs from that Monday when the claim form and particulars are served together. If particulars are served separately, calculate the response deadline from their service.
Getting the deemed date wrong is one of the most common mistakes litigants in person make. It matters because the 14-day response deadline starts from the deemed date of service, not from the date you posted the letter.

Form N215: Certificate of Service
When you serve the claim form yourself, CPR 6.17 requires you to file form N215 — the Certificate of Service — at the court. N215 confirms:
- What document you served
- On whom you served it
- The method of service
- The date and time of service
- The address where it was served
Where CPR 6.17 requires a certificate, N215 records service and must be filed before a claimant can request default judgment based on their own service of the claim form.
When to file N215
File N215 within 21 days after service of the particulars of claim, unless every defendant has acknowledged service within that period. The certificate is not required for every document a party serves. Where CPR 6.17 requires the certificate, it must be filed before the claimant requests default judgment based on their own service of the claim form; a claim form served by the court does not require a claimant's certificate.
Common service problems
Serving at the wrong address for a limited company — CPR 6.9 allows service at the registered office or at a place of business in the jurisdiction with a real connection to the claim. Check Companies House and the facts about the company's place of business before serving.
Missing the deemed date calculation — Posting on a Friday means the deemed date is the following Tuesday (the second business day after posting). The 14-day response clock starts Tuesday, not Friday.
Not filing N215 after serving the claim form yourself — If you served the claim form, file the certificate within the CPR 6.17 period. A certificate is not required just because you served another document yourself.
The County Court Money Claim Guide includes a service deadline calculator and a completed N215 example so you can track every document and its deemed service date from filing through to the hearing.
