Record retention
You must retain a copy of the SAR form and the original or business record equivalent of supporting documentation. You must retain this material for five years from the date of the filing of the SAR. You must identify and maintain the supporting documentation as such and make it available to appropriate law enforcement agencies upon request. [12 CFR 21.11(g)] See the later section of this chapter having to do with the liability shield for details on the relationship between this availability requirement and the requirements of the Financial Privacy Act.
