What actually happens in a commercial dispute?
Far more negotiation than litigation — the overwhelming majority of commercial disputes settle, and the ones that reach a trial are a small fraction. Understanding the process matters mostly because it shapes what your position is worth at each stage.
The sequence:
The dispute arises, usually over scope, quality, payment or termination.
Correspondence, where much is won or lost. Write as though a judge will read it, because one might — intemperate emails become evidence, and "without prejudice" only protects genuine settlement discussions, not everything you label.
A letter before action, setting out the claim, the basis and what you want.
Pre-action protocols, which require parties to exchange information and consider alternative dispute resolution before issuing. Ignoring them carries costs consequences even if you win.
Alternative dispute resolution, most commonly mediation. A neutral facilitates settlement without deciding anything, it settles a large proportion of cases, it costs a fraction of trial, and courts expect you to have tried it — unreasonable refusal to mediate can be penalised in costs.
Issuing proceedings, if that fails.
Disclosure, where both sides produce relevant documents including those that damage their own case. This is frequently the point where cases settle, because the documents rarely support anyone's recollection.
Witness statements and expert evidence.
Trial, and judgment.
Enforcement, which is a separate problem — winning a judgment is not the same as being paid, and against a company with no assets it may be worth nothing.
What drives the economics:
Costs generally follow the event in England and Wales, so the loser pays a substantial proportion of the winner's costs — which makes litigation high-stakes and makes early settlement rational.
Part 36 offers, a formal settlement mechanism with cost consequences for a party who refuses and then fails to beat it. This is the most powerful tactical tool available.
Time, typically a year or more, consuming management attention throughout.
What to do from the start: keep contemporaneous records, preserve documents once a dispute is foreseeable, and take advice early rather than after the correspondence has hardened.
