If you are notarizing any legal document (including a Will), the notary will require the presence of — and require documentation to confirm the identities of — the person(s) signing the legal documents as witnesses to a maker’s signature.
At the same time, note that Standard Legal’s Last Will and Testament documents are ‘self-notarizing’, meaning that a notary is not always required to make the Wills valid. For complete details, see Standard Legal’s Last Will and Testament legal forms software page.
