I live in TN, My children and I were hit in an auto accident on 6/9 by a lrg local produce company?

We went to the emergency room and followed thru with physical therapy, we have completed everything. I hired an attorney and now have found out that we are waiting for Nationwide insurance to come with a settlement amount, It has been weeks and my attorney says they have yet to contact him. is there a required time for insurance companies to respond to this matter? And if so how long? Please don’t say ask my attorney. I am asking Yahoo Members.
