Medical negligence claim time limit

Time limit for medical negligence claims:

The general rule under the Limitation Act 1980 is that you have three years to bring a claim for personal injury, which includes medical negligence.

However, the three-year period does not always run from the date of the negligent treatment itself. There are different starting points depending on the circumstances.

Date of knowledge:

The three-year period runs from the later of either the date of the negligent act or omission, or the date on which you first had knowledge (or ought reasonably to have had knowledge) that you had suffered a significant injury attributable to the act or omission of the defendant. This is set out in sections 11 and 14 of the Limitation Act 1980.

This is important because in many medical negligence cases the patient does not realise until much later that something went wrong. The clock only starts ticking from the point you knew or should reasonably have known that your injury was potentially caused by the treatment you received.

Children:

If the injured person was under 18 at the time of the negligent treatment, the three-year limitation period does not begin to run until their 18th birthday. They then have until they turn 21.

Persons lacking mental capacity:

If the injured person lacks mental capacity within the meaning of the Mental Capacity Act 2005, the limitation period does not run at all while that incapacity continues. The three-year period only starts once they regain capacity, if they do.

Court's discretion:

Even if the limitation period has expired, the court has a discretion under section 33 of the Limitation Act 1980 to allow a claim to proceed if it considers it equitable to do so. The court will weigh up all the circumstances, including the length and reasons for the delay, the effect of the delay on the quality of evidence, the conduct of the defendant, and the extent to which the claimant acted promptly once aware of the potential claim.

Fatal cases:

Where the patient has died as a result of the negligence, a claim under the Law Reform (Miscellaneous Provisions) Act 1934 or the Fatal Accidents Act 1976 must generally be brought within three years of the date of death or the date of knowledge of the dependant or personal representative, whichever is later.

Practical points:

1. Do not assume you are out of time without checking your date of knowledge carefully. Many people believe they are time-barred when they are not, because the clock only starts when they had or should have had the relevant knowledge.

2. Equally, do not delay. Even where the section 33 discretion exists, it is always better to bring a claim well within time. Delay damages evidence, witness recollection, and the availability of medical records.

3. If you think you may be close to the deadline, you should act quickly to get the claim started or at least issue protective proceedings, which can preserve your position even if the full case takes longer to prepare.

One clarification on jurisdiction: you mentioned the UK. This answer covers the position in England and Wales. Scotland and Northern Ireland have their own limitation rules and different time limits. If your claim relates to treatment in Scotland or Northern Ireland, you would need to check the rules for that jurisdiction.
