Planning document information


You need to submit evidence if you are applying for a certificate of lawful use for an existing development. The evidence needs to show why you believe the development is lawful.   


The evidence  you submit should be clear, easy to read and jargon free. 

You must label any photographs with an explanation of what they show. 

The types of evidence you submit may include: 

  • photos which confirm the development was completed or in place before a specific date 
  • utility bills which confirm that the building was being used as such for that period of time 
  • affidavits and sworn statements which confirm when the building was completed or what it was being used for at a specific date 
  • historic documents which show that the development was completed or in place before a specific date 
  • any other documents which you feel may support your application 

You can get help and advice from our Duty Planner on evidence and other types of planning applications. 

You can get detailed feedback on your proposal by using our pre-application advice service
