If you need to open a bank account in another state and cannot do so via the telephone, e mail or facsimile, you can sign a power of attorney designating your father as your agent in fact to do so.I recommend that you have an attorney draft such a document but, there are online forms that you can find as a template for such. Likewise you can go down to your local county law library and view templates for the needed power of attorney. The librarian can assist you in this endeavor.
