Yes, there is a time limit on a medical negligence case.
All medical negligence claims are subject to limitation periods. In England and Wales medical negligence claims must generally be brought, court proceedings issued, within three years of the personal injury.
The time limits include three years from the date of death, if the limitation period has not expired by that time, or three years of knowledge of the facts giving rise to the claim.
Children, not with a disability, typically have until they reach 21 to start court proceedings.
Persons with a disability, who lack capacity, are not subject to any limitation period.
