Building a useful timeline for a civil dispute

A clear timeline makes a legal dispute easier to assess. Begin with the agreement and record the dates of performance, invoices, complaints, payments, and attempts to resolve the problem. Link each important entry to a document or the person who witnessed it.

Separate what you personally observed from what someone later told you. Keep original messages and attachments rather than relying only on cropped screenshots. If dates are uncertain, say so and explain the source of your estimate. A useful timeline also identifies gaps, such as a missing change order or an unexplained payment. Those gaps can guide further document requests. The aim is to help the decision-maker follow the relevant events without searching through unrelated correspondence.

Use one entry for each significant event and a consistent date format. A practical entry might identify an accepted quote, the message accepting it, and the people involved. Avoid putting legal conclusions into the event column: record the actual words or conduct, then explain their significance separately. Include unfavourable events as well as helpful ones. An unanswered complaint, missed appointment, or revised instruction may be important to understanding why the other party disputes your version of events.

Next, connect the chronology to the issues that must be decided. A payment dispute may turn on authorization, completion, and the balance owing; a property damage dispute may turn on cause, notice, and repair cost. Number the supporting documents and use the same references throughout your notes. Keep an untouched copy of the underlying records. Your timeline is an aid to preparation, and its accuracy should be checked against the evidence before it is used in a settlement discussion or hearing.
