Ownership certificates A to D and the notices you must serve
Certificate A, B, C or D depends on who owned the land 21 days before the application. Here is who must be served, the agricultural holdings declaration and the title checks to do first.
Every planning application carries an ownership certificate, and getting it wrong is one of the few mistakes that can follow a permission around for years. Certificate A says you own all the land inside the red line. Certificate B says you do not, but you know who does and you have served them notice. Certificates C and D deal with owners you cannot identify, and both require a newspaper advertisement. The trigger date is 21 days before the date of the application, and "owner" includes anyone holding a lease with at least seven years left to run.
Self-builders trip on this most often when the red line crosses a verge, a shared driveway or a strip of land the seller forgot to mention.
What each certificate means and when to use it
| Certificate | Position | What you must do |
|---|---|---|
| A | You are the sole owner of the whole site, and no part is an agricultural holding with a tenant | Sign the certificate |
| B | You know the other owners | Serve notice on each of them and list them with the dates |
| C | You know some owners and cannot trace the others | Serve notice on those known, take reasonable steps to find the rest, publish a newspaper notice |
| D | You cannot identify any owner | Take reasonable steps, publish a newspaper notice |
Ownership is tested as at the day 21 days before the application date. That matters where a sale completes mid-process: the person who owned the land on the relevant day is the person to serve, whoever owns it when you press submit.
The certificate sits on the application form and is a statutory requirement. A local planning authority is not permitted to entertain an application without one, which is why an incorrect certificate stops validation rather than causing a problem later.
Serving notice on a freeholder or leaseholder
The notice itself is a prescribed form under article 13 of the Development Management Procedure Order 2015. It tells the recipient that an application is being made, describes the development, identifies the land, and explains how they can make representations.
Three practical points.
Serve on the freeholder and on any leaseholder with seven years or more unexpired. A monthly tenant is not an owner for this purpose, and a company holding a 999 year lease certainly is.
Serve by post to the address on the register, and keep proof of posting. Where a company is involved, serve at the registered office.
Record the date of service on the certificate accurately. An officer checking a Certificate B looks at the date first, and a date after the application date is an immediate query.
Agricultural holdings and the separate declaration
The agricultural holdings certificate is a separate declaration on the same form, and it is not the same question as ownership.
It asks whether any part of the land is, or was in the previous 21 days, an agricultural holding within the meaning of the Agricultural Holdings Act 1986, and if so, whether notice has been served on every tenant. A field let on a farm business tenancy or an older agricultural tenancy needs the tenant served, whoever owns the freehold.
Grazing licences and short seasonal arrangements are a grey area, and the safe course is to serve where there is any doubt. Serving an unnecessary notice costs a stamp. Failing to serve a necessary one costs the certificate.
Unknown owners and the newspaper route
Where an owner cannot be traced, Certificates C and D require reasonable steps to find them and a notice published in a newspaper circulating in the locality.
Reasonable steps means something you can describe: a Land Registry search of the title and adjoining titles, an index map search for unregistered land, enquiries of the local authority, enquiries of neighbours and any occupier, and a site inspection for evidence of use. Write down what you did and when, because the certificate is a statement you are personally responsible for.
The newspaper notice has to be published no earlier than 21 days before the application. Local newspapers have copy deadlines, so allow a fortnight for the arrangement rather than assuming you can place it the same week.
Keep the page. A tear sheet or a dated PDF of the published notice goes on the file with the certificate.
Getting it wrong: the consequences for the permission
Two separate risks.
The first is criminal. Issuing a certificate that is false or misleading in a material particular, knowingly or recklessly, is an offence under section 65 of the Town and Country Planning Act 1990. Prosecutions are rare, and the provision is there.
The second is practical. A neighbour or a co-owner who was never served may complain, and the authority may invite a fresh application. Where the matter reaches court, the position established in the case law is that a defective certificate does not automatically render a permission invalid, and relief is discretionary. That is thin comfort when a funder's solicitor finds it during due diligence on a completed scheme.
The commercial risk is the one that bites. A defective certificate is a title problem, and it surfaces at sale or refinancing rather than at construction.
Land registry searches before you sign
Before certifying anything, buy the official copies. It costs very little and it takes an afternoon.
- Official copy of the register and title plan for the application site.
- Official copies for every title the red line touches, including verges and access strips.
- An index map search where any part of the land appears unregistered.
- A check of the title plan against the red line at the same scale, overlaid.
- A check for rights of way, restrictive covenants and any rentcharge affecting the land.
- A site inspection to see whether anyone is using land you believe you own.
Step 4 is the one people skip. Title plans and site plans rarely align first time, and the discrepancy is usually where the problem lives.
A worked example on a site with a ransom strip
Illustrative example. A self-build plot with access taken across a 2 m strip between the plot and the adopted highway. The seller's plan showed the strip as part of the plot. The official copy showed it registered to the estate developer from a 1970s transfer.
The red line has to include the strip, because the access is part of the development. The applicant is not the owner of that land, so Certificate A is wrong and Certificate B applies, with notice served on the registered proprietor at its registered office.
Serving the notice does not give you a right to use the strip. That is a separate negotiation and, in a ransom situation, an expensive one. What the notice does is make the application lawful and put the owner on notice, which occasionally prompts a conversation that would otherwise have happened after you had spent money on the design.
This example is illustrative, and the terms of any real strip depend on its title.
Do the title work before the design work. The Planning Statement can be written in an afternoon; a ransom strip discovered after permission cannot.

Frequently asked questions
Who counts as an owner for the ownership certificate?
The freeholder, and anyone holding a lease with at least seven years unexpired. A monthly or short tenant is not an owner for this purpose, while a company holding a long lease certainly is. Ownership is tested as at the day 21 days before the date of the application, so a mid-process sale does not change who must be served.
When do I need Certificate C rather than B?
Certificate B applies where you know all the other owners and have served each of them. Certificate C applies where you know some but cannot trace the others: you serve those you know, take reasonable steps to find the rest, and publish a notice in a newspaper circulating in the locality no earlier than 21 days before the application.
What is the agricultural holdings certificate?
A separate declaration on the same form asking whether any part of the land is, or recently was, an agricultural holding under the Agricultural Holdings Act 1986, and whether every tenant has been served. It is a different question from ownership, so land let on a farm business tenancy needs the tenant served whoever owns the freehold.
What happens if I sign the wrong certificate?
Issuing a certificate that is false or misleading in a material particular, knowingly or recklessly, is an offence under section 65 of the Town and Country Planning Act 1990. Case law establishes that a defective certificate does not automatically invalidate a permission and relief is discretionary, but it becomes a title problem that surfaces at sale or refinancing.
Does the red line have to include the access?
Yes, where the access forms part of the development. That is why ransom strips matter: if a strip between the plot and the adopted highway is in someone else's title, it sits inside the red line, Certificate A is wrong and Certificate B applies. Serving the notice does not give you a right to use the land.
