Certificate C and D: notice and advertising costs

Certificates C and D are the ownership certificates you use when you cannot find all the owners of the land in your application. They are the only two that require you to advertise, and the advertising is where the cost and the delay sit. The newspaper notice has to be published in a paper circulating in the locality, and it has to be done before you submit, which means the certificate route decides your submission date.

Most people reach for Certificate C or D for the same reason: a strip of unregistered land at the back, an access over a track with no identifiable owner, or a converted building where part of the curtilage was never brought onto the register.

When the advertising route applies

The four ownership certificates under the Development Management Procedure Order 2015 run in a sequence, and you must use the one that matches the facts.

"Owner" for this purpose means the freeholder or a leaseholder whose lease has at least seven years unexpired. A tenant on a short commercial lease or an assured shorthold tenancy is not an owner for certificate purposes, which surprises landlords. Agricultural tenants are dealt with separately within the certificate and need their own notice.

The land in question is the application site as you have drawn it, so the red line on the site plan defines who you must notify. Where an awkward strip is not needed for the development, redrawing the site boundary to exclude it is often faster and less expensive than advertising, provided the development does not in fact require it. Where the strip provides the access, it cannot be excluded.

What reasonable enquiry means in practice

There is no statutory checklist, which means the test is what a reasonable person in your position would have done, and the record you keep is what proves it.

The enquiries that an authority expects to see:

• a title search against the land, including a search of the index map to establish whether the land is registered at all
• inspection of the site, including looking for fencing, maintenance, grazing, storage or any other sign of occupation
• enquiries of the neighbouring owners and occupiers, in writing where possible
• a notice placed on the land itself, which is not a statutory requirement for these certificates but is good evidence of effort
• enquiries of the local authority, including the estates team and any highway records for adopted status
• a company search where an old title names a company that may have been dissolved
• enquiries of the parish council or local historical society on long-standing unregistered land, which is more productive than it sounds

Unregistered land is the common case, and the practical reality is that a search of the index map returning no registered title ends the paper trail. At that point physical inspection and local enquiry are all you have, and the record of them is what supports the certificate.

Keep everything. Dated copies of the searches, copies of letters sent with proof of posting, photographs of the site notice, and a short chronology. If the certificate is ever challenged, the chronology is the document that answers it.

Placing and evidencing the notice

The notice must be published in a newspaper circulating in the locality of the land. That means a local or regional paper with genuine circulation in the area, not a national title and not a free sheet with no real circulation in that locality.

The notice content is prescribed. It identifies the applicant, describes the development, gives the address of the land or describes it where it has no address, states where the application may be inspected, and invites any person claiming to be an owner to contact the applicant. Use the prescribed form rather than drafting your own, because an incorrectly worded notice can invalidate the certificate.

Timing is the part that catches people. The notice must be published no earlier than 21 days before the application is submitted. Service of notice on identified owners is subject to the same 21-day window. So the sequence is: complete the enquiries, serve any Notice 1 on identified owners, place the newspaper notice, wait for publication, then submit within 21 days of the publication date.

Evidence the publication properly. Obtain a certificate of publication or a tear sheet from the newspaper showing the notice and the publication date, and submit a copy with the application. Authorities routinely hold applications at validation for exactly this document.

Land registry searches and their cost

The searches are the least expensive part of the exercise and the part most often skipped.

A search of the index map establishes whether any part of the land is registered and identifies any title numbers affecting it. Where a title is found, the register and the title plan tell you the proprietor and the extent. Where nothing is found, the land is unregistered and you have your answer, which is itself the evidence supporting the certificate.

Fees for downloading a title register or a title plan are published by HM Land Registry and are a few pounds per document, with the index map search charged separately. Both are revised from time to time, so check the current fee schedule on gov.uk rather than budgeting from a previous transaction. Where the land may be subject to a caution against first registration or to a commons or town and village green registration, those are separate searches.

A conveyancer can do all of this, and on a straightforward site it is not difficult to do yourself. The reason to use a conveyancer is where the title is complicated, where a dissolved company appears on the register, or where land may have passed to the Crown as ownerless property, because the next steps in those cases are legal rather than administrative.

Timing against the application submission

Build the certificate route into the programme rather than discovering it at submission.

1. Define the red line on the site plan and list every parcel within it.
2. Run the searches and identify every owner you can, allowing a week.
3. Carry out and record the physical and local enquiries, allowing two to three weeks for responses.
4. Decide which certificate applies.
5. Serve notice on identified owners, and instruct the newspaper notice.
6. Allow for the paper's copy deadline and publication cycle, which for a weekly title can be up to a week before publication.
7. Submit within 21 days of publication, with the tear sheet or certificate of publication attached.

The whole sequence is four to six weeks on a site with one unidentified parcel, and longer if local enquiries produce a possible owner you then have to pursue. Newspaper notice costs vary considerably by publication and by the depth of the notice, so get a written quotation at the start rather than assuming a figure, and remember that a notice that has to be republished because of an error in the wording is paid for twice.

Where cost planning for the application as a whole is the question, the pricing page sets out what PlanScope charges for the supporting reports, and comparable fee mechanics are covered in full application fees by floorspace and site area and how planning fees are indexed each April.

Risk of getting the certificate wrong

This is not a form-filling technicality. 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, and conviction carries a fine.

The practical risks come in three forms.

The permission is vulnerable. An owner who was not notified can complain, and where the authority accepts that the certificate was wrong it may treat the application as invalid, revisit the decision, or in serious cases the permission can be challenged. A permission with a defective certificate is a title problem on sale, and a buyer's solicitor will find it.

Validation delay. Authorities check certificates, and the commonest reasons for a hold are a missing publication certificate, a notice published more than 21 days before submission, or Certificate A used where part of the site is not in the applicant's ownership. Certificate A on a site that includes an adopted highway verge or a shared access is a frequent error.

Relationship cost. Serving notice on a neighbour you did not know owned part of the land is a conversation best had before the notice arrives, not after.

Recording the enquiries made

Create one file before you start and put everything in it: the site plan with each parcel numbered, the index map search result, each title register and plan obtained, every letter sent with the date and the method of posting, every reply, photographs of the site notice with dates, the newspaper quotation, the published notice and the publication certificate, and a one-page chronology.

Keep that file with the planning permission. It is the document that answers a challenge years later, and on a sale it is what allows a solicitor to be satisfied without reopening the whole question. The report index covers the supporting documents the application itself will need alongside the certificate, and ownership questions on phased sites are touched on in outline and reserved matters fees on a phased scheme.
