Detailed guide to what happens when a personal injury claim is disputed in England and Wales. Learn how liability disputes affect the claims process, the role of pre‑action protocols, negotiation, alternative dispute resolution, court proceedings, time limits and costs considerations. Clear, expert information for claimants and solicitors.

In England and Wales, many personal injury claims are resolved quickly when the defendant (often an insurer) accepts liability and agrees compensation. However, disputes are common, particularly over liability (who was at fault) and quantum (the value of losses). When a claim is disputed, the straightforward path to settlement becomes more complex. This article explains what happens when a personal injury claim is contested, the legal framework that applies, practical steps claimants can expect, potential outcomes, and how disputes are resolved in and out of court. The content is structured to be clear and accessible for all readers while retaining legal precision.
Why Claims Are Disputed
A personal injury claim may be disputed for several reasons:
- Liability is denied: The defendant disputes that they owed a duty of care or that they breached it.
- Causation is contested: The defendant accepts the accident occurred but denies that it caused the claimed injuries.
- Disagreement on evidence: The other side challenges the strength or relevance of medical reports or witness statements.
- Quantum is disagreed: The defendant disputes the valuation of pain, suffering or financial loss.
Insurers or defendants must explain their reasons for disputing a claim under the Civil Procedure Rules (CPR) and associated Pre‑Action Protocols before court proceedings start. These rules are designed to encourage early resolution and a fair exchange of information.
The Pre‑Action Protocol: Early Dispute Resolution
Before litigation begins, both sides are generally required to comply with the Pre‑Action Protocol for Personal Injury Claims. The protocol sets out steps to encourage early disclosure of information, exchange of documents, and negotiation to resolve disputes without court intervention. It aims to:
- Ensure each party understands the issues in dispute.
- Encourage settlement without formal proceedings.
- Provide documents necessary to clarify each side's position.
- Allow alternative dispute resolution (ADR), such as mediation, to be considered.
For low‑value road traffic accident claims, a separate protocol (the RTA Small Claims Protocol) applies and provides specific rules for dispute handling within the Official Injury Claim portal. If liability is denied under this protocol, the claimant may challenge the decision and, if unsuccessful, proceed by issuing court proceedings.
Responding to a Dispute
When Liability Is Denied
If the defendant denies liability, your solicitor will usually:
- Review the defendant's reasons and evidence.
- Collect additional evidence, such as witness statements or expert reports, to support liability.
- Communicate further with the defendant's insurer to attempt to resolve disputes without litigation.
If these steps do not lead to resolution, your solicitor may issue court proceedings on your behalf. Court action signals a formal dispute that requires judicial determination if settlement fails.
When Quantum Is Disputed
Even if liability is accepted, disputes may arise over how much compensation should be paid. In these cases:
- Parties exchange medical evidence, schedules of loss, financial records and other documents.
- Negotiation continues, often with formally structured Part 36 offers under the CPR to encourage settlement.
- If parties cannot agree, litigation may become necessary to have a judge decide the appropriate award.
Issuing Court Proceedings
When negotiation fails, the claimant can issue a claim form at the County Court or, in higher‑value cases, the High Court. Issuing proceedings means:
- The court formally becomes involved and sets a timetable (directions) for the case.
- The defendant must acknowledge service and normally file a defence denying or limiting liability within prescribed time limits.
- Both sides exchange evidence, including medical reports, witness statements, and documentary disclosure.
- Specialist forms such as the allocation questionnaire decide whether the claim proceeds on the small claims track, fast track, or multi‑track depending on value and complexity.
Despite proceedings being issued, settlement remains possible at any stage. Most personal injury claims still settle before a final hearing.
Alternative Dispute Resolution (ADR)
Even where a claim is disputed, courts and legal practice encourage ADR methods before trial. Parties may use:
- Mediation: A neutral third party helps both sides negotiate a settlement.
- Arbitration: A third party makes a binding decision.
- Early neutral evaluation: An expert provides an opinion on strengths and weaknesses.
Refusing to consider ADR without good reason can influence court decisions on costs orders after trial.
Trial and Final Hearing
If ADR and negotiation do not resolve the dispute:
- The case proceeds to a trial (final hearing) before a judge - not a jury - who will decide liability and assess damages.
- Both sides present evidence, question witnesses, and make legal submissions.
- Judges determine outcomes on a balance of probabilities, meaning the claimant must satisfy the court that it is more likely than not that the defendant is liable.
Trials are less common in personal injury cases; only a small proportion of claims reach this stage, with most settling earlier in the process.
Time Limits and Limitation Periods
If a dispute results in court proceedings, it is still critical to observe limitation periods under the Limitation Act 1980. For most personal injury claims, you must issue proceedings within three years of the accident or from when you first knew your injury was caused by negligence. Failure to comply with this deadline usually prevents you from pursuing compensation.
Costs and Risk Considerations
A disputed claim can lead to increased legal costs. In personal injury claims, Qualified One‑Way Costs Shifting (QOCS) typically protects claimants from paying the defendant's costs if they lose, except in certain circumstances such as dishonest or unreasonable conduct. This rule reduces the financial risk for claimants when pursuing disputed claims.
However, if a Part 36 offer is not beaten at trial, a claimant may be liable for some costs from the date the offer expired. Expert legal advice is crucial when considering offers and settlement strategy.
Common Questions
Can I still claim if liability is denied?
Yes. You can challenge a denial by gathering further evidence, negotiating, using ADR, and if necessary issuing court proceedings to have a judge decide liability.
Will my case always go to court if disputed?
No. Most disputes are resolved through negotiation or ADR before formal litigation. Court proceedings are a last resort when a fair settlement cannot be agreed.
What if the defendant admits liability but disputes compensation?
The claim proceeds with negotiations focused on quantum. If parties cannot reconcile differences, court determination may be necessary.
Key Takeaways
When a personal injury claim is disputed in England and Wales, the process becomes more structured and evidence‑intensive. Disputes usually arise over liability or quantum of compensation and are addressed through:
- Pre‑Action Protocols that encourage disclosure and negotiation.
- Collection and exchange of additional evidence.
- Consideration of ADR before formal proceedings.
- Issuing court proceedings where settlement cannot be reached.
- Trial before a judge if necessary.
Although disputes can lengthen the claims process, the structured approach and legal protections such as QOCS help manage risk. Early legal advice and careful preparation of evidence are key to navigating disputed personal injury claims effectively.
