Using Proof platform on your mobile device
The Proof platform allows users to notarize documents on their mobile phone via a web browser without downloading an app, enabling signers to perform all transaction actions on their device, while witnesses can join meetings on mobile or computer except on-demand witnesses who must use a computer, and real estate transactions cannot be completed through the Notarize app but must be done via a browser.
The short answer: You can get documents notarized on your phone using the Proof platform with the web browser of your choice — no app download required.
⚠️ Transactions sent to signers by a business are best completed using the Proof platform via a web browser on a computer, laptop, or mobile device. Real estate transactions cannot be completed in the Notarize app.
Signers
Open the Proof website on your phone's browser to get started. Using a browser on your phone is ideal for when you don't have a computer or are away from home.
Signers can complete the same actions on their phone as they can when using a computer, including:
- Uploading their own transactions and adding notes
- Adding, moving, and deleting notations
- Filling out fields and applying signatures and initials
- Changing settings, such as payment method, password, etc.
The experience is the same regardless of the device used, but screens may look a little different from one device to another as they automatically adjust to fit the device.
Witnesses
Document witnesses, credible identifying witnesses, and Florida property remote witnesses (real estate transactions on Florida properties only) can join meetings with a computer or a mobile device.
On-demand witnesses who are answering witness calls from the on-demand queue must use a computer to act as a witness.
Summary Checklist
- Use a web browser on your phone — no app download needed for most transactions.
- Real estate transactions cannot be completed in the Notarize app — use a browser on your mobile device instead.
- On-demand witnesses must use a computer, not a mobile device, to answer witness calls from the queue.

Witnesses on the Proof Platform – Proof Help Center
Proof's platform supports several witness types for transactions—including credible witnesses who verify signer identity, document witnesses who observe signing, Florida property witnesses who observe remotely under specific conditions, and on-demand witnesses called during sessions—while it does not support signature witnesses (proxy signers) or subscribing witnesses (attestations), with a maximum of two witnesses allowed per meeting alongside the notary and signer.
Witness Guidelines for Signers – Proof Help Center
The Proof Help Center's Witness Guidelines for Signers explain that witnesses, who are neutral third parties observing document signing, may be required based on the document or recipient's rules rather than notarial law, and signers can either use a remote witness via Proof's On-Demand Witness feature or bring their own in-person witness who meets criteria such as being over 18, having no interest in the transaction, and complying with document or state requirements, while noting that notaries should not act as witnesses except in specific eligible cases.
Estate Planning with Proof: Remote Execution for Estate Documents
Proof is a technology platform enabling remote electronic execution of estate planning documents like wills and powers of attorney, but it is not a law firm, does not provide legal advice, and requires users to consult their own legal counsel to ensure compliance with varying state laws and document types before using its e-signature and remote online notarization services.
Notary Capacities Overview
Proof supports three notary capacities—On-Demand Notary (ODN), Notary-Sourced Transaction (NST), and In-House Notary (IHN)—each with distinct setup processes and transaction scopes, where ODNs serve the Notarize Network's on-demand queue in select states, NSTs operate independently for their own clients, and IHNs work within organizations with permissions set by admins, all requiring review and approval before activation.
Why Can't I Be an On-Demand Notary? – Proof Help Center
To become an On-Demand Notary on the Notarize Network via Proof, you must hold a current commission in Florida, Nevada, Pennsylvania, Texas, or Virginia, but if your state is not active, you can still serve clients digitally as a Notary-Sourced Transaction (NST) notary while awaiting your state's inclusion, with updates available through Proof’s Compliance Map and waitlist.
