OFAC Attorney: An OFAC subpoena is a formal demand from OFAC for records, documents, and information. The issuance of an OFAC subpoena usually indicates that the person receiving the subpoena is under investigation by OFAC for potential violations of sanctions regulations. A person receiving the subpoena is generally required to comply with the subpoena within 30 days. If 30 days is not enough time, a person can request additional time to comply with the subpoena. People should always be aware that any materially false or misleading statements made to OFAC in response to a subpoena can form the basis of a separate criminal prosecution for false statements.
