Eschatocol

An eschatocol, or closing protocol, is the final section of a legal or public document, which may include a formulaic sentence of appreciation; the attestation of those responsible for the document, which may be the author, writer, countersigner, principal parties involved, and witnesses to the enactment or the subscription; or both. It also expresses the context of the documentation of the action described therein, i. e., enunciation of the means of validation and indication of who is responsible to document the act; and the final formulae.

Common in European medieval charters, they have been relegated to notarial acts, governmental acts, diplomatic treaties, certificates, and other formal documents.
