A lawyer will ensure that you get what you deserve after the accident as opposed to what the insurance companies want to give you which is little to nothing. Car insurance companies operate based on the principle of the three Ds: DENY, DELAY & DEFEND. This means that insurance companies will first try to DENY your injury claim. The main reason is that you should not talk or otherwise interact with car insurance companies like State Farm, Geico, Best Car Accident Lawyers Allstate or Progressive after an accident without a lawyer. So as to put you in a pressured position in which you are more prone to accept less for your injuries and other damages. Finally, insurance companies will tirelessly DEFEND against your claim. So as to put you in a pressured position in which you are more prone to accept less for your injuries and other damages.
