Quick checklist
Start with these
Start With The Relationship And Terms
Identify the agent, principal, territory, products or services, start date, written terms, variations and how the relationship operated in practice. If there was no signed agreement, explain how the arrangement was formed and performed.
This guide is general preparation information only. It does not decide whether a person is a commercial agent or what remedy is available.
- Agency agreement, standard terms, side letters and variations.
- Emails or messages showing appointment, duties, territory and authority.
- Commission structure, payment dates, statements and disputed calculations.
- Orders, invoices, sales data, customer records and performance reports.
- Termination notice, breach notice, restraint wording and handover documents.
Show The Dispute And Loss
Separate what is admitted from what is disputed. A barrister will usually need to know whether the issue is unpaid commission, termination, compensation, indemnity, restraint, breach of authority, customer ownership, confidential information or another commercial issue.
Prepare a short loss schedule showing the calculation, assumptions and supporting documents. If urgent relief is being considered, identify exactly what event creates urgency.
Pre-Action And Court Route
The CPR pre-action conduct practice direction expects parties to exchange enough information to understand each other's position and consider settlement or ADR before proceedings, unless urgency or a specific protocol changes the position.
A barrister may advise, draft a letter of claim or response, prepare pleadings or represent at a hearing. Service, filing, disclosure management and continuing correspondence may require solicitor support.
Source note: source-checked against CPR pre-action conduct and GOV.UK Circuit Commercial Court guidance on 17 September 2026. Commercial agency status, compensation, indemnity, termination, restraint, jurisdiction and limitation issues need specialist commercial barrister or compliance review before publication.
