A chronology is a list of the important events in a dispute, set out in date order. Each entry gives a date and a short, factual description of what happened, often with a reference to the document that supports it. It is one of the simplest and most useful documents in a civil case. The value of a chronology is that it lets anyone, especially a judge, grasp the shape of a case quickly: what happened, in what order, and over what period. A dispute that feels tangled in narrative form often becomes clear once it is laid out as a sequence of dated events.

What a good chronology looks like

A useful chronology is:
  • In strict date order, earliest first
  • Factual and neutral in tone, not argumentative
  • Concise, one event per line, described briefly
  • Supported, with a reference to the document or evidence for each entry where possible
It records what happened, not what it means. Interpretation and argument belong in other documents. The chronology’s strength is that it is hard to argue with a plain, sourced list of dates.

Why courts value them

Judges deal with many cases and limited time. A clear chronology reduces the effort needed to understand a case, which is one of the most helpful things a party can do. It also helps the party who prepares it, because building a chronology often reveals gaps, such as a key event with no supporting document, while there is still time to address them.

​
It underpins other documents

A chronology is not only useful in itself. It provides the backbone for a witness statement, which usually tells events in order, and it helps identify which documents matter, feeding into an exhibit index. Many people find that building the chronology first makes everything that follows easier.
