What is online notary software?

Online notary software runs a legally recognized notarization over a live video call, called remote online notarization or RON. The platform verifies the signer's identity with knowledge-based questions and government ID analysis, connects them to a commissioned notary on camera, applies a tamper-evident electronic seal, and stores an audit trail and recorded video that states require, so a document is notarized without either party leaving home.

Do I need an on-demand notary or my own?

It depends on who signs. If you notarize your own or your clients' documents and already have commissioned notaries on staff, a bring-your-own-notary platform like BlueNotary or OneNotary is cheaper per session. If you need a signer verified at any hour with no notary of your own, an on-demand network like Proof or NotaryCam supplies a live notary in minutes, which matters most for consumer and closing work.

How to choose

1. 1Confirm state coverage first: RON law is state by state, so verify the platform is authorized where your signer and your commission sit before comparing features.
2. 2Decide on-demand versus your own notary: consumer and closing volume favors an on-demand network like Proof or NotaryCam, while a firm with staff notaries saves with BlueNotary or OneNotary.
3. 3Weigh identity and audit needs: real estate and high-value documents demand strong KBA, credential analysis, and video retention, where Proof, SIGNiX, and Pavaso are built for scrutiny.
4. 4For real estate closings specifically, prioritize title and e-closing integrations, where Pavaso, Nexsys, and Stavvy focus.

What is the best online notary software in 2026?

Proof, formerly Notarize, is the best all-around online notary software, because it combines the largest on-demand notary network, strong identity verification, and deep title and enterprise integrations. BlueNotary and OneNotary are the strongest value picks for notaries and small firms that bring their own commission, and NotaryCam is a long-standing on-demand option for real estate.

Is remote online notarization legally valid?

Yes, remote online notarization is legally valid in the large majority of US states that have passed permanent RON laws, provided the notary is commissioned for RON and uses an approved platform. Validity depends on following the specific state's identity-proofing, recording, and journal requirements, which is why platform state coverage is the first thing to check.

How much does online notarization cost?

A single on-demand notarization typically runs about 25 dollars for the first notarial act on consumer platforms, with additional seals costing less. Bring-your-own-notary platforms like BlueNotary and OneNotary charge lower per-session or subscription rates because you supply the notary, and enterprise and title volume is priced by custom contract.

What is the difference between RON and e-signature?

An e-signature only captures a signature electronically, while remote online notarization adds a commissioned notary who verifies identity on video and applies a notarial seal with a legal audit trail. Tools like DocuSign started in e-signature and added a notary product, whereas Proof, NotaryCam, and SIGNiX were built around notarization and its stricter identity and recording rules.
