Remote online notarization and court acceptance
No express recipient-acceptance source was identified in the official materials reviewed.
Remote online notarization is performed under the law of the online notary's commissioning state. When the commission is a Florida commission, Florida's remote online notarization statute governs the notarial act. The court or other recipient still decides whether to accept the return.
If the page is only a declaration, certificate, or signed return, do not add a notary certificate.
