To serve court papers on an individual in England and Wales, you normally use their usual or last known residence. If they have moved, the rules expect reasonable steps to find a current address, which a tracing enquiry can support.
That short answer hides most of the practical difficulty. People move, landlords change and a business address on an old invoice may have been empty for a year. This guide explains what the rules say about addresses for service, the steps worth taking before papers go out, and where a private investigator fits in. It is general information, not legal advice. The rules described here are the Civil Procedure Rules (CPR) for England and Wales, and your solicitor should confirm how they apply to your documents.
What the rules say about the address
Part 6 of the Civil Procedure Rules ↗ sets out where a claim form may be served. In outline, CPR 6.9 says where to serve:
- An individual: usual or last known residence.
- An individual trading under a business name: usual or last known residence, or principal or last known place of business.
- A company registered in England and Wales: principal office, or a place of business with a real connection with the claim.
Other rules can take priority, for example where the defendant has given an address for service or a solicitor has confirmed they will accept service. Personal service, where the papers are left with the person, is also possible in many cases.
The important detail is in rule 6.9(3). If you have reason to believe the person no longer lives or trades at the address you hold, you must take reasonable steps to find their current address. If you find it, you serve there. If you cannot, you must consider whether there is an alternative place or method, and that usually means an application to the court.
Steps before you serve
- Check what you already hold. Note each address, where it came from and when it was last known to be correct. Returned post, a "gone away" note or a neighbour's comment are all relevant.
- Check public records. For a company, the registered office on Companies House is a starting point. Our guide to checking a company on Companies House explains how.
- Decide whether the address is reliable. An old directory entry or social media profile is a lead, not a confirmed current address. Our guide on 192.com and public directories explains the limits.
- Commission a trace if needed. Where ordinary searches have run out, a people tracing or debtor tracing enquiry may establish a verified lead.
- Brief the process server. Give the address, the basis for believing it is current, the deadline and the evidence of service you need. Our free guide to preparing documents for service includes a checklist.
Keep a dated note of each step. If the address later turns out to be wrong, that record helps your solicitor show what was done.
Where a private investigator helps
A tracing enquiry starts with the purpose. We discuss your relationship to the person and the intended use of the result before assessing the work. A legal matter is a legitimate reason to locate someone, but it does not remove their right to privacy, and a result is checked against other relevant information rather than passed on because a name appears in a database.
The outcome may be a verified lead, a need for more information, or an explanation that the available material is not enough. If a current address is found, PDC also offers process serving across the UK, so the trace and the attempt at service can be planned together. Tell us the deadline at the start.
We cannot promise that a person will be found, that they will be at home or that an attempt at service will succeed. What we can provide is an accurate record of what was established and what happened at each attendance.
If you cannot find a current address
An unsuccessful trace or attendance is still information. Rule 6.15 allows the court to permit service by an alternative method or at an alternative place where there is good reason, and the application must be supported by evidence. A clear account of the reasonable steps taken is the kind of material your solicitor may need. Whether to apply, and how, is a legal decision for them. If you do not have a solicitor, GOV.UK explains how to find legal advice ↗.
Once papers are served by you rather than the court, rule 6.17 generally requires a certificate of service, using form N215 ↗, within the time the rules allow.
Talking to PDC
If you have papers to serve and are not confident the address is current, get in touch with a short outline: who needs to be served, the address you hold, why you doubt it and the deadline. We will tell you plainly whether a trace is realistic and what it would involve.
Frequently asked questions
Can I serve a claim form at someone's last known address?
Often, yes. For an individual, CPR 6.9 allows service at their usual or last known residence. If you have reason to believe they no longer live there, you must take reasonable steps to find a current address first. Your solicitor can confirm what applies to your claim.
Will the court serve the papers for me?
In many civil claims the court serves the claim form itself unless you tell it you will serve it (CPR 6.4). If the court's attempt fails, you may then need to serve it yourself, which is often when a current address becomes the problem.
Can a private investigator find someone's address to serve court papers?
A tracing enquiry can sometimes establish a current, verified address, but no investigator can guarantee a trace. PDC discusses the purpose first and checks a possible match against other information before treating it as current.
What if the person cannot be traced?
An honest record of the steps taken is still useful. Your solicitor can use it to decide whether to apply to the court for service by an alternative method or at an alternative place under CPR 6.15, which must be supported by evidence.
Do these rules apply in Scotland or Northern Ireland?
No. This guide covers the Civil Procedure Rules for England and Wales. Scotland and Northern Ireland have their own rules, and papers going abroad need separate consideration. Take advice on the jurisdiction before you act.
