Oftentimes insurance companies reject claims and deny compensation for victims of a car accident simply because the claimant is delayed in filing a claim or seeking medical treatment. There is no specific length of time for when insurance adjusters will deny claims based on unreasonable delay, but customary practice dictates that waiting more than 2-3 weeks to file a claim or seek medical treatment does not bode well for a successful settlement. As such, it is imperative to document injuries and file a claim as soon as possible.
