Yes, you can swap attorneys at anytime. The attorney you hired to defend you in a criminal case has an ethical duty to stay in contact with you and to promptly return your phone calls. If he fails to do so, you have plenty of reason to fire your lawyer and request a refund of any unearned portion of the retainer fee. Once you retain a new lawyer, he will file a Certificate of Representation with the court, notify the prosecutor of his representation, and request all of the case file documents from your former attorney.
The best defense is to insure that the new attorney has a complete mastery of all the facts. In order to accomplish that goal, the lawyer needs to stay in constant contact with his client and continue to acquire new information about the case. There is no better source of information than a client with first hand personal knowledge of the facts of the case.
If you or someone you know has hired a criminal defense attorney who does not return phone calls, you need to swap attorneys and hire attorney Robert J. Shane. Call for a free phone consultation at (612) 339-1024.
