Process serving is the process of formally delivering legal documents to a person or business. Getting this step right protects due process and keeps a claim on track. This guide sets out how service works in England and Wales.
What does process serving involve?
In most civil cases, the process relates to documents such as a claim form, Particulars of Claim, court order, statutory demand, or various family law notices. The papers must be delivered in a way the court recognises as fair, reliable, and verifiable, and then proven with a Certificate of Service (Form N215), or a sworn statement
The detailed rules are set out in Civil Procedure Rules (CPR) Part 6 and Practice Direction 6A.
Without proof of proper service, a case may be delayed or even struck out. The person being served must be notified of legal proceedings, so they have an opportunity to respond.

Who enacts process serving?
Court papers can be served by anyone aged 18 or over who is not directly involved in the case. However, it is highly recommended to instruct a professional process server to do it on your behalf, as they understand the legal system and CPR.
Hiring a professional ensures that service is done correctly, promptly, and in a way the court will accept. It also provides an independent record of the event, which is vital if service is ever challenged.

Which methods of process serving are valid?
Several routes of service are permitted. The court will expect you to pick one that is suitable and provable.
Personal service
This is the preferred and often default method of service. A professional process server tracks down the recipient and delivers the documents to them in-person. Solicitors can also accept service where written authorisation is given. If the recipient is evasive or abroad, servers use professional tracing services.
First-class post or DX
For most documents, the CPR and PD 6A set out deemed service on the second business day after posting, if that day is a business day, or otherwise on the next business day
Electronic service (email)
Email is only valid where the recipient (or their solicitors) has given written consent to a specific address.
Court-authorised alternative service
If standard service isn’t possible, the court can allow alternative methods, such as emailing without prior consent or leaving the documents with another adult at the address (called substituted service), provided the method is likely to bring the documents to the person’s attention. An application must explain the attempts already made and why the alternative is suitable.
How does process serving work in practice?
Once the documents are ready, your process server will:
- Confirm the recipient’s details and address.
- Attend the location, often at varying times of day to increase the chance of contact.
- Deliver the documents using a permitted method under CPR Part 6.
- Record full details of service, including the time, date, location, method, and any notes about the recipient’s behaviour (for instance, if they refused to accept the papers).
- A Certificate of Service (Form N215) or a sworn statement is then filed with the court as proof of service.
The total length of time this takes usually ranges from a day to a week, but for some cases it may take longer.
What if the recipient refuses to accept served documents?
Refusal of papers does not prevent service. If the recipient is correctly identified and the documents are left within their presence — for example, placed on a table or at their feet — the court will usually regard this as valid service.
If service otherwise fails, a process server may conduct a lawful stakeout, overseas service, or another method of delivery (with court approval). You can read more about your options in such cases here.
What happens if service is delayed or not completed in time?
Missing a deadline for serving legal documents can cause problems for your case. See our blog for detailed information about how late service works, “deemed service” rules, and the consequences of missing a deadline.
Need help serving court documents?
Serving court documents correctly is one of the most important steps in any legal process. It ensures fairness, protects your position, and keeps your case on schedule.
While it may sound straightforward, the rules and proof requirements under the Civil Procedure Rules (CPR) can be complex, and mistakes can lead to costly delays or rejected claims. That’s why using a professional process server gives you complete confidence that everything has been handled lawfully and efficiently.
