attestante

Attestante is an Italian noun derived from attestare, meaning to certify, attest, or confirm. An attestante is a person who attests a statement or document, i.e., who certifies its authenticity, accuracy, or conformity. In legal and administrative contexts, an attestante may be a witness who signs to attest the validity of a document, such as a copy or a signature, or an official who issues an attestation asserting that a fact or condition is true or verified. The term can also be used more broadly for professionals who provide attestations of conformity, compliance, or origin within regulated processes, where an authorized person confirms that certain criteria have been met.

The usage of attestante varies with context. In notarial acts, the notary or an entrusted official may perform attestation, while in corporate, academic, or public administration settings an authorized employee, auditor, or external verifier might issue an attestation.

Related terms include attestazione (the act or document of attestation), attestato (certificate or attestation), and testimone (witness), with testimone representing the broader notion of someone who testifies in a proceeding rather than certifies an earlier document.
