Very simple. You don't. Refer that call to your attorney's office. Or, simply let the adjuster know that you are represented and give the adjuster your attorney's information. Sometimes there are exceptions to that rule. Those exceptions would include dealing with your car when your car is damaged in an automobile accident. You will be notified sometimes from what is called a property adjuster. That property adjuster is specifically dedicated to dealing with the damages of the vehicle, evaluating the damages of your vehicle, and dealing with whether or not the vehicle is going be repaired, or deemed a total loss. In those limited cases, it's okay to speak with the at-fault insurance company. But if you're not certain that this is the only reason they're calling you, refer them to your attorney.
