What should a witness do if they notice missing requirements during a signing session?

When a witness notices missing requirements during a signing session, it is crucial to notify the notary and lock the document. This action ensures that the integrity of the signing process is maintained, as it prevents further actions on a document that is not in compliance with necessary legal stipulations. Locking the document gives the parties involved the opportunity to address the missing requirements properly, without risk of modifications or misunderstandings occurring during the signing itself.

This approach adheres to standard protocols, helping to safeguard both the signer's and the witness’s interests, as well as ensuring that all legal criteria are met before the document can proceed. It emphasizes the importance of ensuring that all necessary elements are present to validate the signing session and protect the involved parties. Other options, such as alerting the legal advisor or rescheduling the signing, could lead to inefficient handling of the situation and potential delays, while proceeding without addressing the missing requirements could result in a legally deficient document.
