What does attestor mean?
An attestor is a person who attests something — that is, who formally witnesses or certifies the truth, authenticity, or validity of a statement, signature, or document. The word belongs primarily to legal and formal contexts, where documents such as wills, contracts, deeds, and affidavits require confirmation by someone other than the principal party. An attestor does not create or agree to the contents of a document; rather, they vouch that what they observed was genuine, such as confirming that a signature was made voluntarily by the correct person. It functions as a synonym of 'witness', though it carries a slightly more technical flavor. Variant forms include 'attester' and 'attestant'. The term derives from Latin roots relating to witnessing and proof, sharing ancestry with words such as 'testify' and 'testimony'.

Every valid will needs a pair of eyes on it — and those eyes are called attestors, a word hiding inside 'attest' for centuries.

Etymology of attestor
Attestor comes from the Latin verb 'attestari', meaning 'to bear witness to', formed from 'ad-' ('toward') plus 'testari' ('to call to witness'), itself rooted in 'testis', meaning 'witness'. The same root gives English 'testify', 'testimony', 'testament', and 'testator'. The word entered English through legal usage, alongside its variants 'attester' and 'attestant'.
