Ownership certificate errors and invalid applications

An ownership certificate error is one of the few mistakes that can stop a planning application before anyone looks at the drawings. Every application has to be accompanied by a certificate stating who owns the land within the red line and confirming that notice has been given to anyone else with an interest. Tick the wrong box and the authority can decline to validate the application, which costs weeks. Sign a certificate you know to be wrong and you have committed an offence.

The usual cause is not dishonesty. It is a shared driveway, a verge in council ownership, a strip of land nobody has looked at the title for, or a flat where the freehold sits with a management company.

What each certificate declares

Four certificates exist, and you complete exactly one. The requirement comes from section 65 of the Town and Country Planning Act 1990, with the detail in the Development Management Procedure Order 2015.

Each certificate also carries a declaration about agricultural tenancies, which is dealt with below.

Certificate A is the one people over-use. It says you own all of it, and all of it means the whole area inside the red line, including any part of a shared access, verge or boundary strip you have drawn in to show the access arrangement.

Who counts as an owner

The definition is wider than the registered proprietor of the house.

An owner, for these purposes, is the freeholder of any part of the land, or a person holding a lease with at least seven years unexpired. So a long leaseholder is an owner, and so is the freeholder above them. On a flat, that usually means both the leaseholder and the freehold company, and on an estate with a management arrangement it can mean a third party holding the amenity land.

Three situations produce most of the errors.

A shared driveway where the title shows a strip in joint ownership, or in the ownership of the neighbour subject to a right of way. Drawing the drive inside the red line brings the other owner into the certificate.

Highway verge or footway crossing, which is usually owned or maintained by the highway authority. Where the application includes a dropped kerb or a new access, the land outside the property boundary is somebody else's.

Unregistered land, often a narrow strip behind a boundary or a former lane. Where the ownership cannot be established after reasonable enquiry, certificate C or D is the correct route, not certificate A.

Serving notice on other owners

Where certificate B applies, the notice must be served before the application is submitted, and the certificate records the date it was served.

The notice itself is a prescribed form telling the owner that an application is being made, describing the development and the site, and explaining that they may make representations to the authority. Keep proof: a copy of the notice as served, the date, the method, and the address used. Recorded delivery is sensible on anything contentious.

Two practical points. Notice to a company goes to its registered office, which you can confirm from the public register rather than guessing. And where you serve notice on a management company or a landlord's agent, serve on the owner as well, because an agent's receipt is not always treated as service on the owner.

A notice served after the application was submitted does not retrospectively cure the certificate. The authority will normally ask for a corrected certificate with the later date, and may restart the publicity period.

What happens when the certificate is wrong

Three different consequences, depending on how the error arose.

An honest error picked up at validation. The authority asks for a corrected certificate, you serve the notice you missed, and the application proceeds from the later date. Irritating rather than fatal.

An error discovered during determination, often because the unnotified owner contacts the council. The authority will usually require the certificate to be corrected and the publicity period rerun before issuing a decision. On a contested application that delay matters.

A certificate issued knowingly or recklessly containing a false or misleading statement. That is an offence under section 65 of the 1990 Act, prosecutable and punishable by a fine. In practice prosecutions are uncommon, which is not a reason to treat the declaration casually. An applicant who has signed a false certificate has handed an objector something far more damaging than a design criticism.

Correcting an error before determination

The sequence is straightforward once you accept the delay.

1. Establish the correct position from the title, using the registered titles for the application site and anything adjoining that is inside the red line.
2. Decide which certificate is right. Where ownership of part of the land cannot be established after reasonable enquiry, certificate C is correct and the advertisement is published.
3. Serve the prescribed notice on each owner, keeping proof.
4. Submit the corrected certificate to the case officer with a short covering note explaining the change.
5. Expect the authority to recalculate the determination date and, where publicity is affected, to rerun the 21 day period.

Tell the case officer promptly rather than waiting to be asked. Officers deal with this routinely and are generally helpful about it; what they react badly to is finding out from an angry neighbour.

An alternative worth considering is reducing the red line so that the land in other ownership falls outside the application site, where the development does not actually require it. Land in the applicant's control that is not part of the application is shown in blue instead. That does not work where the scheme depends on the land, such as a new access over a shared drive.

Effect on a permission already granted

This is the question that worries buyers and lenders, and the honest answer is that it depends.

A permission granted where the notice requirements were not properly met is not automatically void. The courts have approached the consequences by looking at the circumstances, including whether anyone was prejudiced by the failure. A person who should have received notice and did not may be able to challenge the decision, and challenges to planning decisions are subject to short time limits, so the position changes quickly with the passage of time.

What that means in practice. On a recent permission with an unnotified owner who objects, take legal advice, because the options include correcting the position and reapplying rather than relying on a vulnerable consent. On an old permission already implemented, the practical risk is usually different, turning on enforcement and on any private law rights the other owner holds. Either way this is a point for a solicitor rather than a planning consultant, and it is also why an unnotified owner sometimes becomes involved in an appeal, as our note on third party involvement in someone else's appeal explains.

Agricultural holdings notices

The certificate also asks about agricultural tenancies, and this part is skipped more often than any other.

You must state whether any part of the land to which the application relates is, or was within the 21 days before the application, used for agriculture, and whether any person other than the applicant was an agricultural tenant. Where there is an agricultural tenant, notice must be served on them.

On a farm diversification or a field edge development this is a live issue, because grazing licences and informal arrangements are common and the occupier may hold a tenancy without either party using that word. Ask the question explicitly before completing the form.

Avoiding the problem on shared land

Do the title work before the drawings are finished, not at submission.

Obtain the registered title and plan for the property, and for any adjoining land you intend to include. Compare the title plan with the proposed red line, and mark anything that falls outside it. Where the access crosses verge or footway, assume the highway authority is an owner unless the title shows otherwise. Where the property is leasehold, identify the freeholder and any intermediate landlord. Where a strip appears unregistered, record the enquiries you made.

Then write the ownership position into the Planning Statement in a sentence or two, with the certificate relied on named. It costs nothing and it tells the validation officer you have thought about it.
