Keep the originals and work from copies
Before organising a dispute or investigation, gather the records you already hold legitimately into one secure location. Keep original documents and files unchanged. Make separate working copies if you need to highlight passages, add notes or remove irrelevant information for an initial discussion.
Start an index rather than renaming everything in a rush. Give each item a reference such as D01, D02 and D03, with its existing filename and a short description. This lets you refer to the same email or invoice consistently without losing its original context.
Use a small set of columns
A spreadsheet or simple document is enough. Put one event on each row and sort by the date of the event, while keeping the date of the supporting document separately where those differ. If the time is unknown, leave it unknown rather than inventing precision.
- Event date: include the time only when relevant and known.
- What happened: one neutral sentence describing the event.
- Source: the document reference, page or message that supports it.
- Status: confirmed by a record, reported by someone, or your recollection.
- Open question: the point that remains unresolved.
Make the wording neutral and specific
For example, write ‘Email D04 says delivery will occur on 12 May’ rather than ‘They lied about delivery’. Put your concern in a separate note. This allows another reader to assess the evidence without inheriting your conclusion.
Keep full message threads where you have them. A cropped image can omit the surrounding exchange, date or sender details. Where two records conflict, include both and mark the discrepancy. Your timeline becomes more useful when it reveals uncertainty instead of hiding it.
Prepare a short handover
End with a one-page overview containing the main question, five or six key dates and the documents most relevant to the next decision. Keep the longer chronology available, but do not bury the issue beneath every minor exchange.
If proceedings are involved, ask your solicitor how material should be preserved and presented. A home-made timeline is an organising aid, not a ruling on what a court will accept. PDC can offer basic pointers on whether your outline is clear enough for an initial assessment.
Questions you may have
Should I include events I can only remember?
Yes, if relevant, but label them as recollections and mark uncertain dates. Keep them distinct from events supported by contemporaneous records.
Should I delete documents that contradict my account?
No. Preserve relevant originals and flag contradictions. Ask your adviser about any duties to retain material in a dispute.
