The quick answer is maybe. It depends on the type of insurance coverage you have and whether you will be making a claim to your own insurance company. Often, pursuant to your agreement with them, your insurance company is entitled to your statement regarding the accident. However, even when you are required to provide your insurance with a statement you need an attorney to protect you because anything you say to them could potentially be used against you.
Remember, insurance companies work together and share information so they can pay as little as possible to settle your claim.
