Ownership certificates A to D: which one to sign
Sign Certificate A only if you own every square metre inside the red line. Where an access crosses someone else's land, notice has to be served and the 21 day clock runs before you submit.
Sign Certificate A only if you own every square metre inside the red line and there is no agricultural tenant. That is the whole test, and it is where most self-builders go wrong, because the red line usually has to include an access over land somebody else owns. Get it wrong and the council cannot lawfully entertain the application, a neighbour gains a ready-made ground of challenge, and a knowingly false certificate is a criminal offence.
The four certificates come from Article 13 of the Town and Country Planning (Development Management Procedure) (England) Order 2015. They are a sworn statement about ownership, not a formality on the last page of the form.
What each certificate declares
| Certificate | When it applies | What you must have done |
|---|---|---|
| A | You are the sole owner of the whole application site | Nothing further |
| B | Other owners exist and you know who they all are | Served notice on every one of them |
| C | Some owners known, some not traceable | Served notice on those known, published a newspaper notice, taken reasonable steps to trace the rest |
| D | None of the owners is known to you | Published a newspaper notice and taken reasonable steps to trace |
Certificate B is the normal position for an infill plot bought from a neighbour with a right of way retained, for a scheme that crosses a shared drive, or for a leasehold property where the freeholder is someone else. It is not a problem to serve notice. It is a problem to pretend you did not need to.
Each certificate also carries the agricultural land declaration, so the form is doing two jobs at once.
Who counts as an owner for this purpose
Owner has a specific meaning here: the freeholder, or a lessee whose lease has at least seven years left to run. A monthly tenant is not an owner. A tenant on a 125-year flat lease is.
That definition catches arrangements people forget. A mortgagee is not an owner. A beneficiary under a trust is not, though the trustees holding legal title are. Where a company owns the land, the company is the owner and notice goes to its registered office. Where a site is held by executors, notice goes to them.
Separately, the certificate asks about tenants of an agricultural holding, which is a different category again and covered below.
Identifying every owner before you sign
Start with the Land Registry title plan for your own land and compare it against the red line you are about to draw. The mismatch is usually at the access.
Order official copies of the register and title plan for your site and for any adjoining strip the red line touches. Where the strip is not registered, a Land Registry search of the index map will confirm that, and you then fall back on documentary evidence: pre-registration deeds, conveyance plans, and historic mapping showing the boundary and who maintained it.
Three places where ownership surprises applicants:
- The verge and footway between the carriageway and your boundary, which is usually highway maintainable at public expense and vested in the highway authority rather than the frontager.
- A shared private drive where the title shows a right of way rather than ownership of the surface.
- A strip of land retained by a developer when an estate was sold off, often a metre wide, sometimes deliberately.
Where the red line has to include any of those, you cannot sign Certificate A. Where the works themselves are entirely within your own land and the access already exists as a lawful right, the red line may not need to extend over it at all. That is a judgement about what the development actually comprises, so take it carefully rather than drawing the smallest line you can defend.
Serving notice and the 21 day requirement
Notice is served using the prescribed form, and it must be served on every owner identified. The timing rule is that the notice is given not more than 21 days before the application is submitted, so you serve, wait, and then apply. Keep proof: a certificate of posting for each recipient, or a signed acknowledgement, and a dated copy of what was sent.
Where you cannot trace an owner, the newspaper notice route applies. The notice goes in a newspaper circulating in the locality, and the publication date must fall within the 21 days before submission. Keep the printed page itself. The invoice from the advertising department proves nothing.
A frequent error is serving notice and then amending the red line before submission. If the site changes, the notice no longer matches the application, and you serve again. Another is serving on the occupier instead of the owner of a let property. The occupier may be neither.
Notice is not a consultation. It does not give the recipient a veto and it does not ask permission. It tells them an application is being made over land in which they have an interest, which is exactly why neighbours who were not notified complain so effectively later.
The agricultural holdings declaration
The certificate includes a declaration about whether any part of the site is, or was within the previous 21 days, agricultural land occupied by a tenant of an agricultural holding. If it is, that tenant must be served notice too.
The point is substantive on rural sites. A field let on a Farm Business Tenancy or an older Agricultural Holdings Act tenancy has an occupier with statutory protection, and a grazing licence may or may not create a tenancy depending on its terms. Where a self-build plot is being carved out of a let field, ask the landowner for the tenancy documents rather than accepting a verbal assurance that the grazier is "just informal".
Where the land is in hand and farmed by the owner, no notice is needed on that count, but the declaration still has to be completed honestly.
Consequences of signing the wrong certificate
Section 65 of the Town and Country Planning Act 1990 prevents a local planning authority from entertaining an application unless the required certificate accompanies it. Knowingly or recklessly issuing a certificate that is false or misleading in a material particular is an offence punishable by a fine.
What happens to a permission already granted is less clear-cut in practice than people expect. The courts have held that a defective certificate does not automatically make a permission void, and relief in judicial review is discretionary, so outcomes have turned on whether the omitted owner was prejudiced and how quickly the point was raised. That is cold comfort during a sale, because a solicitor acting for a buyer or a lender will raise the discrepancy and the quickest answer is usually a fresh application with the certificate corrected.
The practical risks are therefore a delayed or collapsed sale, a vulnerable permission, and an enforcement dispute where implementation relied on land you did not control. Whether a permission has been lawfully implemented is a separate question again, and the tests are set out in our note on a material operation and lawful implementation.
Checking title before submission
Build this into the week before you submit rather than the morning of.
Pull the official copies and title plans. Overlay the red line on the title extent. List every parcel the red line touches and name the owner of each. Where an owner is identified, serve the prescribed notice and diarise the 21 days. Where one cannot be traced, place the newspaper notice and record the steps you took to trace. Then complete the certificate that matches what you actually did.
Keep all of it in one folder with the submitted documents. If the certificate is questioned two years later during a sale, the folder is the answer.
A permission does not override private rights, and this is worth separating in your head. A covenant restricting building on a plot survives a grant of permission, and the difference between the two regimes is explained in our note on covenants and planning conditions. Signing Certificate A does not cure a title defect, and signing Certificate B does not create a right of access.
Illustrative example: a plot at the end of a cul-de-sac, bought with a right of way over the final 12 metres of a private drive owned by two adjoining houses. The red line had to include the drive because the application proposed widening it. Certificate B, two notices served, 21 days diarised, application submitted on day 22. This example is illustrative.

Frequently asked questions
What is the difference between Certificate A and Certificate B?
Certificate A says you own the whole application site and nobody else has a qualifying interest in it. Certificate B says other owners exist, you know who they are, and you have served the prescribed notice on each of them. If the red line includes a shared drive, a verge or a retained strip, Certificate B is almost always the correct one.
Who counts as an owner for a planning application certificate?
The freeholder, and any lessee whose lease has at least seven years left to run. A short term tenant is not an owner for this purpose, and nor is a mortgagee. Where a company holds the land, notice goes to its registered office, and where executors hold it, notice goes to them.
How long before submitting must I serve notice on other owners?
The prescribed notice must be given no more than 21 days before the application is submitted, so you serve first and then apply. Keep a certificate of posting or signed acknowledgement for each recipient and a dated copy of what was sent. If you change the red line after serving, serve again.
What happens if I sign the wrong ownership certificate?
A local planning authority cannot entertain an application without the required certificate, and knowingly or recklessly giving a false or misleading certificate is an offence punishable by a fine. A defective certificate does not automatically void a permission, but it gives objectors a ground of challenge and will be raised by a buyer's solicitor on sale.
Do I need to notify an agricultural tenant?
Yes, where any part of the site is, or was within the previous 21 days, agricultural land occupied by a tenant of an agricultural holding. The certificate carries a declaration on that point. Ask the landowner for the tenancy documents rather than relying on an assurance that a grazing arrangement is informal.
