What is authenticate?
Legal Definition
To authenticate means to verify the genuineness of a document, signature, or identity as required by law or agreement. Proper authentication creates enforceable rights and obligations, binding parties to its terms. The key distinction lies in whether authentication requires independent verification or mere acknowledgment.
Plain-English Translation
Authentication is like showing your library card to prove you're a member before checking out books. It confirms you're who you claim to be before allowing access to something valuable.

Missing or vague
If authenticate is missing or vague
Without clear authentication provisions, parties may dispute whether a document is valid. This can lead to contracts being deemed unenforceable.
