Generally, you must begin your claim within 3 years of the date of the accident. If you do not, you could be prevented from ever doing so.
A number of other rules can change the time limits which apply, however. If you are bringing a claim for someone who does not have the mental capacity to do it themselves, either because of their brain injury or otherwise, the time limit will not ‘run’ whilst they are in this condition. This could easily mean that no time limit applies in their case.
If you are thinking of bringing a brain injury claim, or you are worried it might be too late, contact us as soon as possible so that we can advise you.
