Commercial disputes are mostly decided on documents. By the time a disagreement has hardened into a dispute, the events at its heart are often years old. The people involved have changed roles, left the company, or remember things the way it would be convenient to remember them. What remains is the record: contracts and amendments, emails, meeting minutes, invoices, delivery notes, support tickets, board papers. The party that understands that record first usually frames the fight — and the other side spends the proceedings responding to that frame.
That is why the chronology is not a supporting exhibit prepared once strategy is set. It is the case, and it should be built first.
Memory is a poor client
Every dispute arrives with a story. The commercial team is certain the counterparty changed the specifications; the founder is certain the investor knew; everyone is certain the warning was given. The record often tells the story differently — and with dates. The gap between what people remember and what the documents show is precisely where cases are lost, and it is far better discovered by your own lawyers than by opposing counsel or a judge.
Building the chronology early is how you find that gap while it is still information rather than damage. Sometimes the record is better than the story: the email everyone forgot turns out to prove the notice was given. Either way, you want to know before you commit to a position in writing.
Build the chronology before the strategy
The common order of work is backwards: pick the theory of the case, then hunt for documents that support it. That order feels efficient and quietly filters the record — documents that fit the theory get collected, documents that complicate it get set aside as irrelevant, and the file confirms whatever the first meeting assumed.
A chronology built neutrally, before any theory, does the opposite. Every relevant event goes in, dated and sourced, whether it helps or hurts. Only then do you ask which legal theories the record actually supports. Strategy chosen from the record survives contact with the other side's submissions; strategy imposed on the record does not.
What a working chronology looks like
A working chronology is not a narrative. It is a disciplined table: one line per event, with the date, the actors, what happened, a reference to the source document, and a short note on what the document shows — kept separate from what anyone hopes it shows. Facts and characterisation must not blur, for the same reason they must not blur in an investigation report: the moment they do, you can no longer tell what you can prove.
Built this way, the chronology exposes three things nothing else exposes. Gaps — periods where something must have happened but no document says what. Contradictions — between witnesses and record, or between the counterparty's own documents. And the pivot points — the handful of documents the dispute will actually turn on. In Swiss proceedings, where factual allegations must be substantiated and tied to offered evidence, the chronology maps almost line by line onto the submission you will eventually file.
Factual command is settlement leverage
Most commercial disputes settle, and settlements are moved less by rhetoric than by the other side's dawning realisation that you know the record better than they do — including their own documents. Quoting the counterparty's internal email, with its date and author, does more to a negotiation than any threat of proceedings. It signals that every assertion they make will be checked against a record you have already mastered.
Command of the facts also disciplines your own side. A realistic view of the record makes your risk assessment honest, your settlement range defensible, and your decision to fight — if you take it — an informed one rather than an indignant one.
Getting there at the scale of a real record
The obstacle is volume. A real commercial record runs to thousands of emails and attachments, and the traditional response — junior lawyers reading for weeks — means the chronology arrives late and shapes nothing. This is work systems now do well: reading the full record, extracting dated events with source references, flagging inconsistencies. What they produce is raw material. Deciding which events matter, what the record will bear, and what the case is — that belongs to the lawyer who will stand behind the submissions.
If a dispute is forming and the record is large, the chronology is the first thing worth commissioning, not the last. We are happy to discuss what yours would show.
