A 'Certificate of Lawful Use' (CLU) is a certificate which deems the use of land lawful.
A land owner can apply to the Development & Planning Authority for a Certificate of Lawful Use (CLU). This is done under the Land Planning and Development (Certificates of Lawful Use) Ordinance, 2019. The application form and the Ordinance, which took effect from 6 May 2019, are available in the downloads section of this page. The application form should be submitted to the Authority along with the particulars specified in the form.
Where a CLU is issued by the Development & Planning Authority, it certifies that on the date of the application, the use(s) described in the CLU in respect of the specified land was deemed lawful under the Land Planning and Development (Guernsey) Law, 2005. The use of land is deemed lawful when the CLU is in force.
The Development & Planning Authority has published 
guidance [217kb] which describes the process for obtaining a CLU in more detail.
