The accident was partly my fault —
can I still claim?

Contributory negligence is the legal principle that applies when the person making a claim also contributed to the accident through their own negligence. Under the Law Reform (Contributory Negligence) Act 1945, damages awarded in a personal injury claim are reduced in proportion to the claimant’s share of responsibility for what happened.

This means a claim can succeed even where the claimant was partly at fault — as long as the other party was also at fault. The compensation is not all or nothing: it is adjusted to reflect how responsibility was shared.

A contributory negligence allegation does not mean the claim is invalid. It does not mean the insurer is denying liability entirely. It means the insurer accepts that their policyholder was at fault to some degree, but argues that the claimant also contributed.

It is a position on the split of responsibility — not a decision that the claim cannot proceed. The claim proceeds on the basis of the admitted proportion, and the disputed element can be challenged through the portal.

Where the claimant disputes the contributory negligence percentage, the OIC portal has a formal mechanism for recording and progressing that dispute. The claimant submits their response to the insurer’s position, with supporting evidence where available. The insurer then responds. If the position cannot be resolved through the portal, the matter may proceed to the small claims court for a judicial determination.

The challenge to a contributory negligence allegation is separate from the medical and offer stages of the claim — it is a liability dispute, and liability disputes are handled at the liability stage of the portal process.

Challenging a contributory negligence allegation depends on the evidence available about how the accident happened. Dashcam footage is often the most useful — it shows the sequence of events directly. Photographs of the scene, vehicle positions and road markings can support the claimant’s account. Witness statements from independent witnesses carry weight. A police report, where one exists, provides an official account.

The insurer’s reasons for the allegation tell the claimant what is being disputed — which is also the evidence most relevant to challenge it. If the insurer alleges the claimant was speeding, evidence about speed is relevant. If they allege a failure to indicate, evidence about the claimant’s road position is relevant.

Contributory negligence disputes are one of the clearest situations where regulated legal advice changes the outcome. The argument involves legal assessment of the evidence, knowledge of how courts have approached similar factual situations, and the ability to present the claimant’s account effectively. These are areas where a solicitor’s expertise provides practical value that a claimant navigating it alone may not be able to replicate.

Where the alleged percentage is significant — 50% or more — the financial impact on the settlement is substantial. The cost of taking advice at this point is generally lower than the cost of accepting an unfavourable split.

In a standard rear-end collision, liability is typically admitted in full — the following driver was responsible for maintaining a safe distance. Contributory negligence is sometimes alleged where the insurer argues that the claimant braked sharply or unexpectedly, or that their brake lights were not functioning. These allegations are usually disputed and, where dashcam evidence exists, are straightforward to address.

At junctions, roundabouts and crossroads, contributory negligence allegations are more common because the facts around right of way, positioning and speed can be genuinely disputed. These accidents often involve conflicting accounts from both drivers, and the evidence available determines whose account is supported.

Failure to wear a seat belt is a well-established basis for a contributory negligence reduction — typically 25% where a seat belt would have been available and the injuries would have been reduced or avoided if it had been worn. This is distinct from the circumstances of the accident itself: the allegation is not that the claimant caused the accident, but that they failed to take reasonable precautions against injury.

Where a seat belt was being worn and the allegation is based on a misunderstanding or incorrect assumption, this can be challenged through the portal with supporting evidence.

Accidents involving lane changes, motorway merging or overtaking frequently attract contributory negligence allegations because the facts about road position, signalling and speed are often disputed. These are cases where independent evidence — dashcam footage, witness statements, police reports — is particularly valuable.
