Third-party claim form

A third-party claim form is the document used to formally notify an at-fault driver’s insurer of a claim being made by an injured third party, setting out the basic facts of the accident and the injury.

It is the starting point that separates a third-party bodily injury claim from a claim you might make on your own comprehensive policy, a distinction explained in third-party versus own-damage claims. Supporting documents such as the police report and medical report normally accompany it.

Filling it in accurately from the outset helps avoid unnecessary delays later in the claim.

Some insurers accept this notification by letter or email rather than a fixed form, so the exact format matters less than including all the required facts clearly.
