Preserve sources and context
Keep source files, complete conversations and information about where they came from. Do not edit the originals directly. If annotations are helpful, use a separate working copy clearly marked as such.
Connect events to documents
Build a chronology and number the documents. For each event, note the date, participants, what happened and the associated files. Clearly mark uncertain dates or information that still needs verification.
Record gaps without filling them in
Keep a separate list of missing attachments, incomplete records and details based only on recollection. Organising documents does not determine their authenticity, evidential weight or usability; those questions require further review.
This is general guidance on organising information. It is not legal advice on a particular matter and does not replace an assessment by counsel after review of the facts.
