Validation checks all relevant information and fee (where applicable) has been provided. Validation checks applications against the Cornwall Council Validation Guide:
The guide is made up of:
National Requirements - required by legislation; and
Local Requirements – set by the Local Planning Authority (LPA).
Applicants can use the Validation Guide as a checklist to ensure all the relevant information has been prepared.
Where information is missing the application will be ‘invalid’ and further information requested.
Validation will take no further action until the applicant/agent provides the required information. Validation will return applications after 28 days if the applicant/agent does not provide the information required.
