Justice Manual § 9-27.650

In a case in which a non-prosecution agreement is reached in return for a person's cooperation, the attorney for the government should ensure that the case file contains a memorandum or other written record setting forth the terms of the agreement. The memorandum or record should be signed or initialed by the person with whom the agreement is made or his/her attorney.

Comment. The provisions of this section are intended to serve two purposes. First, it is important to have a written record in the event that questions arise concerning the nature or scope of the agreement. Such questions are certain to arise during cross-examination of the witness, particularly since the existence of the agreement should be disclosed to defense counsel pursuant to the requirements of Brady v. Maryland, 373 U.S. 83 (1963) and Giglio v. United States, 405 U.S. 150 (1972). The exact terms of the agreement may also become relevant if the government attempts to prosecute the witness for some offense in the future. Second, such a record will facilitate identification by government attorneys (in the course of weighing future agreements not to prosecute, plea agreements, pre-trial diversion, and other discretionary actions) of persons whom the government has agreed not to prosecute.

The principal requirements of the written record are that it be sufficiently detailed that it leaves no doubt as to the obligations of the parties to the agreement, and that it be signed or initialed by the person with whom the agreement is made and his/her attorney, or at least by one of them.
