Common mistakes

Upload the document in the Authorised Signatory section under the proof of appointment field, in PDF or JPEG within the size limit. If the same person is also a promoter, you still need the authorisation document.

If it already went wrong

Prepare a corrected resolution or letter answering the defect and upload it with your reply within the time stated in the notice. If the officer has asked for a specific format, follow it.
