OneNotary

OneNotary is a remote notarization service for individuals and organizations, combining online sessions with mobile notary visits. It suits businesses that need notarization connected to legal or operational software, while occasional users can pay per session. The main trade-off is balancing those transaction charges and equipment requirements against its integration and identity-verification capabilities.

Overview

OneNotary supports remote online and mobile notarization. Online appointments use live audio and video, electronic signing and a recorded audit trail, while mobile notarization includes a traveling notary. The service says its professional notary coverage is nationwide and available 24/7, useful when signers cannot work within normal office hours.

It is particularly well suited to organizations embedding notarization into an existing process rather than treating every signing as a separate consumer transaction. The company launched its remote notarization platform in 2020 and is headquartered in Mill Valley, California.

Key features

Identity verification combines biometric checks, credential analysis and knowledge-based authentication. That gives a business several ways to validate a signer before completion, rather than relying on the signing event alone. Each notarization includes a full audit trail, supporting record-keeping and later review.

The REST API supports white-label and embedded integrations. A Clio integration lets users create notarization requests from Clio and receive completed notarized documents there, making it a practical option for legal teams already using that system. Enterprise customers can request custom workflows and integrations, single sign-on and a dedicated account manager.

OneNotary lists SOC 2 Type II, ISO/IEC 27001:2022 and MISMO compliance. Uploaded files can use common text and image formats, including PDF, but each document must be no larger than 35 MB. Online notarization requires Chrome, Safari or a similar browser, an internet connection, camera, speaker and microphone. The mobile experience is delivered through mobile web rather than a separately identified native app.

Pricing

Pay-as-You-Go costs nothing, with online notarizations starting at $25, mobile notarizations starting at $80 and seven days of document storage. It is the sensible entry point for infrequent users, but the short storage period may not suit workflows that need to retain records in OneNotary.

The Online notarization plan costs $25 per notarization, billed per online notarization with one stamp and one signer. An additional seal costs $10, an additional signer $10 and a OneNotary witness $15. This transparent per-event structure fits straightforward single-signer documents; multi-party transactions can become materially more expensive.

Business Professional is $49 a month, billed monthly, with annual billing also offered. Online notarizations start at $25 and mobile notarizations at $80, while the plan adds unlimited storage, unlimited team members and REST API access. It is aimed at recurring business use where shared access and integration justify a subscription.

Mobile notarization costs $80 per event and includes one stamp, five pages and mobile notary travel. It fits documents that require an in-person visit, but additional volume beyond those included allowances may require a different arrangement. Enterprise uses custom pricing and adds a dedicated account manager, custom workflows and integrations, SSO and embedded integration.

Platforms

OneNotary is available through web and API access. Online signers use a compatible browser and required audio-video equipment; mobile notarization is supported through mobile web.

Who it's for

Choose OneNotary when a law firm, operations team or other organization needs identity checks, audit-ready records and a way to place notarization inside its software workflow. Clio users gain a direct request-and-return path, and larger organizations can seek SSO and tailored integrations. Individuals with occasional, uncomplicated needs can use the per-session options, but should account for storage limits and the required camera, microphone and internet connection.

Pros and cons

Pros

• Biometric verification, credential analysis and knowledge-based authentication provide layered signer checks.
• Recorded audit trails and stated SOC 2 Type II, ISO/IEC 27001:2022 and MISMO compliance support controlled business processes.
• REST API, white-label, embedded and Clio integration options reduce manual document handling.
• 24/7 nationwide professional notary availability supports time-sensitive signings.
• Unlimited storage and team members are included in Business Professional.

Cons

Verdict

OneNotary is a strong choice for businesses that need verified remote signers, durable audit trails and API or Clio-connected workflows, with mobile visits available when online notarization is unsuitable. Look elsewhere if you need long free storage, a native mobile app or a lower and more predictable cost for multi-signer or high-page transactions.
