Direct answer: Reply within the written deadline with the requested documents and explain any impossibility. A supplement request is not a refusal.
Who this applies to: Anyone receiving a formal request.
Practical steps: 1) list each document/deadline; 2) gather originals/copies; 3) write numbered cover note; 4) submit through channel; 5) save receipt/files.
Documents to keep: Request, attachments, translations/legalisation, receipt and protocol.
Verifiable timing and costs: Deadline is the one in the notice; translation/legalisation costs vary.
Exceptions and special cases: If a foreign act is impossible, request extension and written confirmation of accepted alternative.
If the procedure stalls: Send proof of request to foreign authority within deadline and state expected date.
Practical example: The office asks for CU and contract; the applicant numbers files and replies on time.
