Legal Question in Insurance Law in Illinois

You as the insured owe a duty to cooperate with your insurer; that's basic insurance law. You may need to review your insurance policy and it may show what you may be required to supply your insurer in the event of a claim -- including personal financial information.

For all we know the attorney needs the affidavit to use against the thieves. You give too little information, however, about the factual situation surrounding the theft or what you reported. If there is some cause for them to think that the "theft" was a set-up and that you somehow profited from the "incident"....there's a lot of that going around. The company may need to document for internal purposes that they've investiated to a reasonable point.

Think of it in part this way: it's somewhat like security at an airport. We all hate the invasion of privacy but know what the alternatives could be..... Here hopefully they are taking the extra steps with not only you but anyone where the "factors" somehow need to rule out the possibility of a fraudulent claim, and this way the company remains solvent to pay you and hopefully not have to raise rates.....

But again without knowing the facts you reported or what the affidavit contains, you should call the agent and the attorney and see if you can find out what is going on. Be polite up front -- you hopefully will get more information that way. If it doesn't "sound" right to you, and if in fact there's some question as to your "innocence", then you may have legal rights here that are being affected, including your right against self-incrimination......and you may need an attorney. And you are entitled to one anyway (your own, not the insurer's attorney, that you will have to pay for) to review the affidavit and see if there's anything in it.
