Third-party claim form

A third-party claim form is how an injured person formally tells the at-fault driver’s insurer about their claim. It sets out the basic facts of the accident and the injury.

It starts a claim against the other driver’s insurer, which is different from a claim on your own comprehensive policy. Third-party versus own-damage claims explains the difference. Supporting documents such as the police report and medical report normally accompany it.

Filling it in accurately from the start helps avoid delays later.

Some insurers accept this notification by letter or email rather than a fixed form, so the format matters less than including all the facts clearly. If you would rather not deal with the insurer yourself, an independent lawyer can take on the claim and send it for you.
