What Is Online Notarization (Remote Online Notary)?
Online notarization (RON) allows you to notarize documents completely online using a secure video platform. You sign digitally and the notary verifies your identity online.

Is Online Notarization Legal?
Yes — online notarization is legally recognized in many U.S. states, but the rules vary.
Many states fully allow RON. Others allow it with conditions. A few still prefer in-person notarization for certain high-risk or real-estate-related documents.
That’s why it is always best to check your state requirements or consult a professional notary service.
