Limitation is the period of time after which you’re not allowed to make a claim against someone who caused an accident. In personal injury claims, the general rule is that the limitation period expires 3 years from the date of accident therefore, if you want to proceed with your claim you will need to do so within that time. Failure to do so may mean you are unable to claim. For children, the 3-year limitation period runs from a child’s 16th birthday.
