Ownership certificate D and notice by advertisement
Signing ownership certificate D states that no owner could be identified after reasonable steps, and obliges you to advertise the application locally. The evidence file is what defends it.
Ownership certificate D is the certificate you sign when you cannot identify any of the owners of the application land after taking reasonable steps, and it obliges you to publish notice of the application in a newspaper circulating in the locality. It is the rarest of the four certificates and the one most likely to be challenged, because signing it is a statement that nobody could be found rather than that nobody was asked.
The framework sits in section 65 of the Town and Country Planning Act 1990 and Article 13 of the Town and Country Planning (Development Management Procedure) (England) Order 2015. Certificate A covers sole ownership. Certificate B covers owners who have all been identified and notified. Certificate C covers the position where some owners were identified and notified and others could not be traced. Certificate D is the complete failure to trace anyone.
When certificate D applies
An owner, for these purposes, is the freeholder or a person holding a lease with at least seven years unexpired. Shorter leases and licences do not count, so a building full of tenants on three-year leases still only has one owner to notify.
Certificate D arises on a narrow set of sites. Ransom strips and verges left out of historic conveyances. Former railway land and canal margins. Back-land accessed over a strip with no registered title. Land whose registered proprietor was a company dissolved decades ago. Unregistered land where nobody has dealt with it since before registration became compulsory in the area.
If you can identify some owners but not others, the certificate is C, not D. Mixing the two up is the most common error and councils do spot it.
Reasonable steps to trace an owner
The legislation requires reasonable steps and does not list them, which means the burden of showing what you did sits with you. A defensible set of steps looks like this.
- Obtain official copies of the register and title plan for the application land and every adjoining title
- Apply for a search of the index map, which reveals whether any part of the land is registered at all
- Inspect the land, photograph it, and record evidence of occupation, maintenance, fencing and use
- Make enquiries of neighbours and occupiers, in writing where possible, and record the responses
- Search the council's own records: planning history, land charges, highway adoption and asset registers
- Where a registered proprietor is a dissolved company, check whether the land has passed to the Crown as unclaimed property, and notify the relevant government department
- Search for probate where an individual proprietor appears to have died
Keep every receipt, every search result and every dated note. The file is the evidence, and a judicial review claimant will ask for it.
Where the land turns out to be registered to a traceable owner after all, serve notice and sign certificate B. Discovering this late is inconvenient and far better than discovering it after permission is granted.
The newspaper notice and its wording
The notice takes the prescribed form in the Order. It names the applicant, describes the proposed development, identifies the land, states where the application can be inspected, and tells any person claiming to be an owner to contact the applicant.
Publish it in a newspaper circulating in the locality of the land. A regional title with a local edition is usually acceptable; a free sheet with no editorial presence in the area is riskier, and online-only publication is not what the Order contemplates.
Three practical points. Check the newspaper's publication day against your submission date before booking. Ask for a voucher copy or a certificate of publication from the publisher, not just an invoice. And read the proof before it runs, because an error in the description of the land means publishing again.
Timing before submission
The notice and the certificate sit inside a 21-day window tied to the date of the application, and councils treat the dates strictly as a validation matter. Work backwards from your intended submission date, confirm the exact requirement in Article 13 for the certificate you are signing, and build in slack for the newspaper's copy deadline.
| Step | Timing to plan for |
|---|---|
| Title and index map searches | Two weeks before the notice is booked |
| Site inspection and enquiries | Before the notice, so the certificate is honest when signed |
| Booking the newspaper notice | Against the publication day, allowing for the copy deadline |
| Signing the certificate | On or just before the submission date, with the publication date entered |
| Submission | Inside the window the Order prescribes |
Do not sign the certificate with a projected publication date. If the notice does not run as booked, the certificate is false.
Evidence to retain
Hold a single bundle containing the title searches with their dates, the index map search result, dated site photographs, copies of correspondence with neighbours and occupiers, the newspaper voucher copy, and a short chronology narrating what you did and when.
That bundle does two jobs. It supports the certificate if the council queries it, and it is the document you hand a purchaser's solicitor who asks how the permission was obtained. On a site where title is already uncertain, the planning file is sometimes the best ownership evidence anyone has.
Set the ownership position out in the Planning Statement as well, in a short paragraph. Officers appreciate knowing why an unusual certificate has been used before they reach the certificate itself.
Consequences of an incorrect certificate
Issuing a certificate that is false or misleading, knowingly or recklessly, is a criminal offence under section 65 of the 1990 Act. That is the headline risk and it is rarely the practical one.
The practical risks are these. The council may refuse to validate the application, losing weeks. An owner who surfaces later and shows they were identifiable may challenge the permission, and the courts have quashed permissions where notice requirements were not met. A lender or purchaser carrying out diligence may treat the defect as a title problem and discount the land. And a planning permission is of no use if the development cannot be built because somebody else owns the access.
Defects of this kind sit alongside other structural problems that make a permission vulnerable, such as the drafting failures described in tailpiece conditions and why they are unlawful.
Title investigation before you certify
Treat the certificate as the end of a title investigation rather than a form to complete at the end of the submission checklist. On any site with a boundary strip, an accessway, a verge, a former industrial yard or anything that looks like a historic sliver, commission the searches at the start of the project.
An illustrative example. A developer assembles a 0.4 hectare site from two registered titles and finds a two-metre strip between them, unregistered, which the proposed access must cross. Index map search confirms no registration. Site inspection shows the strip maintained by neither neighbour. Enquiries produce nothing. Certificate D with a newspaper notice is then the correct route, and the bundle recording all of it becomes the basis for a later possessory title application.
Once the permission is in place, the conditions are the next discipline, and the sequence is set out in conditions you must discharge before work starts. Compare the certificate requirement against your authority's validation list on the report index and the national list before you submit.

Frequently asked questions
What is the difference between certificate C and certificate D?
Certificate C is used where some owners have been identified and notified but others could not be traced. Certificate D is used where none of the owners could be identified after reasonable steps. Both require a notice published in a newspaper circulating in the locality. Choosing the wrong one is a frequent validation error.
Who counts as an owner for the certificate?
The freeholder, or a person holding a lease with at least seven years unexpired at the date of the application. Shorter leases, tenancies at will and licences do not count. Agricultural tenants are dealt with separately on the form, so a farm tenancy needs its own notice even where the landlord is notified.
What counts as reasonable steps to trace an owner?
The legislation does not list them, so keep a documented trail. Official copies of the register and title plan, an index map search, a dated site inspection, written enquiries of neighbours and occupiers, searches of the council's own records, and probate or dissolved company enquiries where relevant all belong in the file.
Where should the newspaper notice be published?
In a newspaper circulating in the locality of the land, in the form prescribed by the Development Management Procedure Order 2015. Check the publication day against your submission date, obtain a voucher copy or certificate of publication from the publisher, and proof-read the description of the land before it runs.
What happens if the certificate turns out to be wrong?
Issuing a certificate that is false or misleading, knowingly or recklessly, is an offence under section 65 of the Town and Country Planning Act 1990. In practice the bigger risks are invalidation, a later challenge by an owner who was identifiable, and a purchaser or lender treating the defect as a title problem.
