Read the checklist for your transaction
Use the issuing authority’s current instructions for the exact request. Record where you found the checklist and when you checked it. Recheck it if the legal entity, applicant or purpose changes.
Read your file like a reviewer
Check that each scan opens, shows the full page and is legible. Compare names and dates with the application. If spellings differ, ask the receiving authority what evidence it accepts to resolve the mismatch.
Keep one final copy and a change log
Save the submitted version and its reference together. When a correction arrives, note which document it refers to, what changed and who confirmed the update. This prevents an older attachment from being sent again.
