Planning application checklists

Lawful development certificate

An application for a lawful development certificate form should be used to establish whether:

  • an existing use of land, or some operational development, or some activity in breach of a planning condition, is lawful

  • a proposed use of buildings or other land or some operations proposed to be carried out in, on, over or under land would be lawful.

For further information, the Planning Portal provides comprehensive guidance.
