Should I Sign These Authorizations / Releases Sent by the Insurance Company?

No. If you are later involved in a lawsuit with the at-fault driver (and his/her insurance carrier), they will obtain medical records regarding your injuries. However, most authorizations prepared by insurance companies during the claim process are far too broad and intrusive. They often request information far beyond what is needed to pay for your actual injuries. Additionally, we believe it is better to finish or stabilize your medical care before providing records to the insurance company. At the Blackwell Law Firm, we want our clients to focus first on recovery and healing from their injuries.
