Pre-Action Requirements Before Starting a Claim
Before issuing a High Court claim, parties are expected to comply with pre-action protocols under the CPR.
This includes:
- Sending a Letter Before Claim
- Setting out the basis of the claim clearly
- Providing supporting documents
- Allowing a reasonable period for response
- Considering Alternative Dispute Resolution (ADR)
Failure to comply may result in cost penalties or procedural sanctions.
Step-by-Step: How to Start a High Court Commercial Claim
Step 1: Assess jurisdiction and limitation period
Before issuing proceedings, confirm:
- The claim is within the High Court's jurisdiction
- The correct court division is selected
- The claim is not time-barred under limitation law
Typical limitation periods include:
- 6 years for breach of contract
- 6 years for tort claims (e.g. negligence)
- Longer periods for certain fraud or concealment cases
Step 2: Prepare the claim form (N1)
Proceedings are started by filing a Claim Form (N1), which must include:
- Names and addresses of parties
- Brief details of the claim
- Remedy sought (e.g. damages, injunction)
- Court fee calculation based on claim value
The claim form initiates formal court proceedings.
Step 3: Draft Particulars of Claim
The Particulars of Claim set out the detailed legal and factual basis of the case.
They typically include:
- Background facts
- Contractual terms or legal duties relied upon
- Breaches or wrongdoing alleged
- Loss and damage suffered
- Interest claims (if applicable)
In commercial litigation, precision and clarity are essential due to the complexity of issues.
Step 4: File documents at the High Court
The claim is issued by filing:
- Claim Form (N1)
- Particulars of Claim (or served separately within 14 days)
- Supporting documents (if required)
- Court fee payment
Filing can be done electronically through CE-File for High Court cases.
Step 5: Serve the claim on the defendant
Once issued, the claim must be formally served under CPR Part 6.
Service may be:
- Personal service
- Service by post or courier
- Service by electronic means (if permitted)
- Service outside the jurisdiction (with court permission where required)
Proper service is critical; defective service can invalidate proceedings.
Step 6: Await acknowledgment of service or defence
After service, the defendant must respond by:
- Filing an Acknowledgment of Service (usually within 14 days)
- Filing a Defence (usually within 28 days total from service)
The response may include:
- Admission of liability
- Full defence
- Counterclaim
- Jurisdiction challenge
Step 7: Case progression and management
Once a defence is filed, the court will:
- Allocate the case to a track (usually Multi-Track)
- Issue case management directions
- Set deadlines for disclosure and evidence
- Schedule Case Management Conferences (CMC)
High Court cases are actively managed to ensure efficiency and proportionality.
