What should a lawyer do if a client uses their services to commit a crime?

When a client uses a lawyer's services to commit a crime, the lawyer faces an ethical dilemma. The correct course of action is to withdraw from representation. This is in line with the Model Rules of Professional Conduct, which state that a lawyer must not assist a client in committing or continuing criminal activity.

By withdrawing, the lawyer can cease involvement in any illegal actions that may be ongoing. It is important for the lawyer to take this step in order to maintain the integrity of the legal profession and adhere to ethical standards. Continuing representation could implicate the lawyer in the client's unlawful activities, thus risking both professional disciplinary action and potential criminal liability.

Other options, such as informing the authorities or assisting in covering up the crime, would not only violate ethical obligations but could also expose the lawyer to serious legal consequences.
