A Certificate of Lawful Use (CLU) is a certificate as to the lawfulness of any existing use of land. Where a CLU is issued by the Development & Planning Authority, it serves to certify that, on the date of the application, the use/s described in the CLU in respect of the area of land specified therein was/were lawful within the meaning of section 22(3) and (4) of the Land Planning and Development (Guernsey) Law, 2005. The lawfulness of any use, at the time of the application, for which a CLU is in force is therefore conclusively presumed.
An owner of land can apply to the Development & Planning Authority for it to issue a Certificate of Lawful Use (CLU) under the Land Planning and Development (Certificates of Lawful Use) Ordinance, 2019. An application form is available in the downloads section of this page, which should be submitted to the Authority along with the particulars specified in the form.
