Mistake #5 - Signing insurance company forms and medical authorizations.
For the same reasons you should not give a recorded statement to the insurance company, you should not sign any forms or medical authorizations that it requests. Again, these forms are used to protect the carrier's interest. The insurance company will be looking for any information in your past medical history to build its case against you. In one case of mine, the client had executed medical authorizations allowing the company to dig far back into her medical history. These records revealed unflattering information about my client to the extent that the information damaged her reputation and made it difficult for me to settle the case for a much higher amount. Please don't help the insurance company by signing documents it asks you to sign.
