§ 20.4 Determination of delinquency; notice.
(a) The agency head (or designee) responsible for carrying out the provisions of this subpart with respect to the debt shall send to the debtor appropriate written demands for payment in terms which inform the debtor of the consequences of failure to cooperate. In accordance with guidelines established by the Chief Financial Officer, a total of three progressively stronger written demands at not more than 30-day intervals will normally be made unless a response to the first or second demand indicates that a further demand would be futile and the debtor's response does not require rebuttal. In determining the timing of the demand letters, agencies should give due regard to the need to act promptly so that, as a general rule, if necessary to refer the debt to the Department of Justice for litigation, such referral can be made within one year of the final determination of the fact and the amount of the debt. When the agency head (or designee) deems it appropriate to protect the government's interests (for example, to prevent the statute of limitations, 28 U.S.C. 2415, from expiring), written demand may be preceded by other appropriate actions, including immediate referral for litigation.
