There are several factors which determine the choice of an attorney to represent a client who has been charged with a crime. These factors include the nature of the charges against the person, the age of the person charged, and the type of criminal charge, if there are any. Most criminal defense attorneys practice within a local jurisdiction. In most jurisdictions, criminal defense attorneys must be licensed or registered with the state Bar Association. A criminal defense lawyer who wishes to practice before the courts must pass the bar exam. Some states have further requirements for lawyers to become certified or registered.
It may be tempting to turn to the services of a public defender rather than retain a criminal defense lawyer. Public defenders, however, are not all created equal. A public defender may not have the experience needed to successfully represent a client. A public defender may not have the skills and resources available to effectively represent a client in a court of law. Because criminal defense lawyers bring a specific type of expertise and knowledge to a courtroom, it is important that the public defender is effective and well-trained in the area of criminal law.

Public defenders may not offer guarantees regarding the outcome of a case. They usually work on a contingency basis, meaning the fees an attorney receives will be for his services only. Attorneys who do not work on a contingency basis, or provide guarantees of outcomes, usually work on a retainer basis. In other words, they are paid a percentage of the final result of a case. If a criminal defense lawyer does not win the case, he does not receive any compensation.
The decision to retain a new attorney might be appropriate if there are serious concerns about a case. Private attorneys are usually more expensive, but some newer models of technology and databases make the fees charged by these new models slightly lower than the fees charged by traditional attorneys. Whether or not to retain a new attorney might also depend upon whether the attorney can be trusted.
Some jurisdictions require a criminal defense attorney to change lawyers every few years. These mandated changes usually take place when a case cannot be defended in court. Some jurisdictions require a new attorney to change lawyers if the client has moved to a different city or state and wishes to retain this new lawyer. Sometimes judges require criminal lawyers to change lawyers based on their success in a particular jurisdiction.
