What action should be taken if a document's signer cannot communicate effectively?

Using an interpreter when a document's signer cannot communicate effectively is essential for ensuring that the signer fully understands the content and implications of the document they are signing. This action aligns with the notary's responsibilities to verify the signer's identity and their willingness to sign without coercion. By utilizing an interpreter, the notary can facilitate clear communication, ensuring that the signer is informed and competent to execute the document.

Proceeding without notarizing or simply refusing service are not appropriate responses, as they may lead to misunderstandings or leave the signer without necessary services. Asking the signer to bring someone else to help can also be problematic; it may not guarantee effective communication and could create delays without ensuring that the signer fully comprehends the document in question. Using an interpreter is the most effective and ethical option in this scenario.
