Time Limits After Serious Injury: Protecting a Claim When the Picture Is Still Unclear

Few subjects cause more quiet anxiety after a serious injury than time limits. Families are often told that there are three years to bring a claim, but they may not know when that clock starts, whether it can pause, or what happens if fault and long-term needs are still unclear. The short answer is that limitation is rarely as simple as counting three years from the date of an accident. The practical answer is that early advice is almost always worthwhile.

The usual three-year period

For most personal injury claims in England and Wales, the limitation period is three years. That period usually runs from the date of the injury or from the date of knowledge, whichever is later. The date of the accident is therefore important, but it is not always the deciding date.

For a road traffic collision, a workplace injury or an accident in a public place, the three-year rule is the starting point. Clinical negligence claims also generally carry a three-year period, again subject to the date-of-knowledge principle. Fatal accident claims have their own rules, usually three years from the date of death or the date of knowledge, and compensation claims to the Criminal Injuries Compensation Authority are subject to a separate two-year time limit. Those differences are one reason why general information should not be treated as a substitute for advice on a particular case.

What date of knowledge means

The date-of-knowledge principle asks when the injured person first knew, or could reasonably have known, that they had a significant injury and that it was attributable in whole or in part to the defendant’s act or omission. That is not necessarily the day of the accident, and it is not necessarily the day a final prognosis is received.

Someone may know they were hurt in an accident but not yet know that the injury is significant. Another person may know they are unwell but not know that a workplace exposure or a delayed diagnosis is responsible. The law looks at what the person knew and what they could reasonably have found out with appropriate advice. This is a fact-sensitive area, which is why families should not assume that a deadline has passed simply because an accident happened more than three years ago. Equally, they should not assume that the date of knowledge gives them unlimited time.

Children and protected parties

Where the injured person was under 18 at the time of the injury, the limitation period does not usually run in the same way during childhood. The three-year period generally begins on the person’s 18th birthday, which means a claim can often be brought until the age of 21. A litigation friend, usually a parent or guardian, can act on the child’s behalf before then, and court approval is normally required for any settlement.

Where an adult lacks capacity to conduct legal proceedings, the limitation clock generally does not run in the ordinary way. Such a person is often described as a protected party. If capacity is later regained, the position can change, and legal advice should be taken promptly. Settlements involving protected parties usually require court approval, and a deputy or attorney may be involved in decisions about the claim and any award.

These protections are important, but they do not remove the need for early advice. Evidence can fade, records can be lost, and opportunities for rehabilitation or interim funding can be missed while everyone waits.

When the court can extend time

For adults, the court has a discretion under section 33 of the Limitation Act 1980 to allow a personal injury claim to proceed even though the limitation period has expired. The court considers factors such as the length of the delay, the reasons for it, the effect on the evidence, and the conduct of the parties. That discretion exists, but it is not a safety net that families should rely on. Applications can be contested, evidence may have deteriorated, and the outcome is never guaranteed.

The sensible approach is to treat limitation as a deadline to be protected, not a problem to be solved later.

Why early advice matters when fault is unclear

Many serious injury claims begin before liability is settled and before long-term needs are known. That does not make advice premature. A solicitor can advise on the limitation position, help preserve evidence, notify insurers where appropriate, and consider whether rehabilitation or interim payments can be funded while investigations continue.

Early advice can also prevent accidental damage to the claim. Families may be asked to sign forms, provide statements or accept early payments without fully understanding the consequences. They may not realise that household insurance includes legal expenses cover, or that a union or employer may have a reporting process. A solicitor can explain what to do without pressuring anyone into a decision before they are ready.

Practical steps families can take now

• Write a clear timeline of what happened, including dates of treatment and any changes in symptoms.
• Keep medical appointment letters, discharge summaries, receipts and photographs in one place.
• Record the names and contact details of witnesses and any professionals involved.
• Report the incident to the police, employer or site operator where appropriate, and keep a copy of any reference number.
• Check home, motor or travel insurance for legal expenses cover.
• Avoid signing settlement or waiver documents without advice.
• Seek legal advice early, even if fault is disputed or the full extent of the injury is not yet known.

Limitation is not meant to be a trap for the uninformed, but it does reward prompt action. The key message is reassuring and practical: families do not need to have every answer before taking advice. They simply need to protect their position while the answers become clearer.
