Proof

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.

The short answer: Proof supports several witness types depending on your transaction — and a couple it doesn't. This guide covers what's available, what isn't, and why.

Witness Types Overview

Available Types of Witnesses

Proof supports several witness types depending on the nature of your transaction:

  • Credible Witness: Vouches for the identity of a signer after successfully completing identity verification.
  • Document Witness: An individual who watches another person sign a document.
  • Florida Property Witness: Personally known to the notary and observes the execution of a document by a person who is in the witness's electronic presence — but not their physical presence. Only available on select transactions that meet specific eligibility criteria.
  • On-Demand Witness: A notary may be able to call an on-demand witness if one is needed during a session.

A total of 10 devices can connect to a single meeting. One must be a notary and one must be a signer — the remaining slots can be any combination of participants (signers, real estate contacts, etc.), with a maximum of 2 witnesses.

Unavailable Types of Witnesses

Not every witness type is supported on Proof. Here are two that aren't available:

  • Signature Witness (Proxy Signer): A signature witness is a notary who officially witnesses or observes someone signing a document as a notarial act. This is different from a document witness and is relatively uncommon — an affirmation or jurat is typically performed instead.

    • Pro tip: A quick way to tell if a signature witness is required: check the notarial certificate. If it reads "Signed (or attested) before me…," that's a signature witnessing.
  • Subscribing Witness (Attestation): A subscribing witness — also called an attestation — watches the signing of a document and then appears before a notary in the principal signer's place to confirm the absent party willingly signed. Some states prohibit subscribing witnesses entirely due to the elevated risk of fraud.

    • Pro tip: If you need someone to sign on another person's behalf, the representative signer feature may be a better fit for your situation.

Summary Checklist

  • Proof supports four witness types: Credible Witness, Document Witness, Florida Property Witness, and On-Demand Witness.
  • A maximum of 2 witnesses can connect to a single meeting, with a total of 10 devices allowed.
  • Signature witnesses and subscribing witnesses are not available on Proof.
  • The representative signer feature may be an alternative for those who need someone to sign on another person's behalf.
