Certificates of Lawful Use FAQs

A Certificate of Lawful Use or Development (CLUD) is a crucial legal tool for confirming that an existing or proposed use of land or buildings is lawful in planning terms. At Interurban Developments Ltd, we regularly help clients secure lawful use certificates to regularise long-standing activities, protect property value, or clarify permitted uses.

Here are answers to the most frequently asked questions.

What is a Certificate of Lawful Use or Development (CLUD)?
A Certificate of Lawful Use (also known as a Lawful Development Certificate or LDC) is a formal decision from the local planning authority that confirms a particular use, building, or activity is lawful for planning purposes — and does not require enforcement action or a planning application.

When should I apply for a lawful use certificate?
You should consider applying if:

• You’ve been using land or buildings without planning permission for a significant period
• You’re unsure if a change of use was lawful
• You need to confirm that development is permitted under current regulations
• You’re selling, refinancing, or leasing a property where planning status needs to be clarified

What’s the difference between existing and proposed use certificates?
There are two types:

• Certificate for Existing Use or Development (Section 150) – confirms that something that has already occurred is lawful (e.g. residential use of a converted barn for 10+ years).
• Certificate for Proposed Use or Development (Section 151) – confirms that a future action or use would be lawful (e.g. building a garage under permitted development rights) or how your use fits with the Use Class Order.

How long must a use or development have existed to qualify?
Timeframes vary depending on the type of development:

• 4 years: For unauthorised building works or use of a building as a single dwelling
• 10 years: For unauthorised changes of use (e.g. commercial, agricultural, or other uses), or breaches of conditions

The relevant use must have been continuous, and the burden of proof lies with the applicant.

What evidence is required for a certificate application?
Typical supporting documents include:

• Sworn affidavits or statutory declarations from witnesses
• Utility bills, council tax records, tenancy agreements
• Photographic or dated evidence
• Business records, accounts, or letters of occupancy
• Maps, plans, and aerial imagery

We help compile and structure this evidence to meet the legal test of “on the balance of probabilities.”

Is a Certificate of Lawful Use the same as planning permission?
No — it does not grant permission, but it provides legal confirmation that no permission is needed. Once issued, it is legally binding and can protect against future enforcement action.

How long does the process take?
Local authorities in Scotland typically aim to determine lawful use applications within 8 weeks. Complex or borderline cases may take longer. We manage the submission and liaise with the planning authority to reduce delays.

What happens if my application is refused?
You can:

• Submit further evidence and reapply
• Appeal the refusal to the Scottish Government’s DPEA, which will assess the case independently

We can guide you through the appeal process or assess whether a retrospective planning application is more appropriate.
