New York Consolidated Laws, Penal Law - PEN § 40.10 Renunciation

1. In any prosecution for an offense, other than an attempt to commit a crime, in which the defendant's guilt depends upon his criminal liability for the conduct of another person pursuant to section 20.00, it is an affirmative defense that, under circumstances manifesting a voluntary and complete renunciation of his criminal purpose, the defendant withdrew from participation in such offense prior to the commission thereof and made a substantial effort to prevent the commission thereof.

2. In any prosecution for criminal facilitation pursuant to article one hundred fifteen, it is an affirmative defense that, prior to the commission of the felony which he facilitated, the defendant made a substantial effort to prevent the commission of such felony.

3. In any prosecution pursuant to section 110.00 for an attempt to commit a crime, it is an affirmative defense that, under circumstances manifesting a voluntary and complete renunciation of his criminal purpose, the defendant avoided the commission of the crime attempted by abandoning his criminal effort and, if mere abandonment was insufficient to accomplish such avoidance, by taking further and affirmative steps which prevented the commission thereof.

4. In any prosecution for criminal solicitation pursuant to article one hundred or for conspiracy pursuant to article one hundred five in which the crime solicited or the crime contemplated by the conspiracy was not in fact committed, it is an affirmative defense that, under circumstances manifesting a voluntary and complete renunciation of his criminal purpose, the defendant prevented the commission of such crime.

5. A renunciation is not “voluntary and complete” within the meaning of this section if it is motivated in whole or in part by (a) a belief that circumstances exist which increase the probability of detection or apprehension of the defendant or another participant in the criminal enterprise, or which render more difficult the accomplishment of the criminal purpose, or (b) a decision to postpone the criminal conduct until another time or to transfer the criminal effort to another victim or another but similar objective.
