The Board of Governors of the Federal Reserve System is proposing to amend Regulation CC to address situations where there is a dispute as to whether a check has been altered or is a forgery, and the original paper check is not available for inspection.  The proposed rule would adopt a presumption of alteration for any dispute over whether the dollar amount or the payee on a substitute check or electronic check has been altered or whether the substitute  check or electronic check is derived from an original check that is a forgery.  This rule is intended to provide clarity as to the burden of proof in these situations.
