22 C.F.R. § 92.34 Fastening certificate to instrument.
Title 22 - Foreign Relations
The proper place for the certificate of acknowledgment is after the signature of the parties to the instrument. If the instrument is a printed form, the certificate will almost invariably be a part of the form. When Form FS–88 is used or when the certificate must be prepared on a sheet separate from the instrument, it should be fastened to the instrument as the last sheet. The method of fastening notarial certificates is prescribed in §92.17.
