A legal issue rarely arrives as a tidy sequence of facts. There may be a phone call, a message, a meeting, and then a document that changes what happens next. Writing those events down in order gives you and your lawyer a shared starting point.
Put events in order
Start with the earliest event that seems connected to the issue, then add the important steps that followed. A line for each event is enough: an approximate date, what happened, who was involved, and any document or message that may support the entry.
Keep the wording plain and factual. Instead of trying to explain what every action meant, note what you observed or were told and leave room for your lawyer to ask follow-up questions.
Separate facts from assumptions
If you are unsure of a date, say so rather than making it look exact. You can label an event as approximate, distinguish a direct conversation from something you heard secondhand, and note where your memory is incomplete.
This kind of honesty makes the timeline more useful, not less. It helps identify which details are established, which may need confirmation, and what records could fill a gap.
Connect entries to records
When possible, note where the supporting material is: an email, a letter, a calendar entry, or a saved message. Keep the original records intact and avoid editing messages or documents to make them fit the chronology.
A timeline does not decide what the law requires or predict an outcome. It is a practical way to help your lawyer understand the sequence, spot questions, and focus the conversation on the facts that may matter.
