Concurrent Signing – Proof Help Center
Concurrent signing in Proof allows multiple signers to simultaneously join a single notary session from separate devices and locations to sign documents together, with options for compulsory concurrent signing to mandate all signers' presence, and features to handle late joiners or disconnections by converting to split signing if needed.
The short answer: Concurrent signing lets multiple signers meet with a notary at the same time — each from their own device and location — without waiting for others to finish first.
Concurrent signing is available for:
- Signers who upload their own document(s) for notarization with two or more signers.
- Transactions sent by organizations (title agents, mortgage lenders, and other businesses) that have this feature enabled by Proof.
To enable concurrent signing for your organization, contact your Customer Success Manager (CSM) or reach out to Proof Support.
How Concurrent Signing Works
- Separate Locations: Signers can be anywhere — no need to be in the same room.
- Same Meeting: Everyone joins the same notary session at the same time.
- Separate Devices: Each signer uses their own device to connect.
All annotations must be made during the meeting. If you want signers to fill out certain fields ahead of time (Sign Ahead), use split signing instead.
Signers may wait in the waiting room until everyone has joined. If a signer chooses to move forward without waiting:
- Additional signers can still join after the meeting begins.
- If the first signer completes the meeting alone, the transaction automatically converts to a split signing.
If a signer gets disconnected, the notary can remove that signer from the meeting so the remaining signers can continue as a split signing. This option may not be available depending on the organization's settings.
Compulsory Concurrent Signing
Use compulsory concurrent signing when all signers are required to be present at the same time — whether that's a document requirement, a company policy, or simply a preference. When this is enabled, signers won't see the option to continue without the others.
Compulsory concurrent signing is set at the account level and applies to every transaction you create. If most of your transactions don't require all signers to appear together, consider skipping this setting and instructing signers to wait in the Waiting Room instead.
What to Expect as a Signer
- 1.Open Your Invitation
- Select the link in your email invitation to get started.
- 2.Verify Your Identity
- Complete the identity verification steps before entering the meeting.
- 3.Enter the Waiting Room
- Wait for the other signers to join. Depending on your transaction settings, you may have the option to continue without them — which converts the meeting to a split signing.
- 4.Join the Notary
- Once all signers are in the waiting room, everyone joins the notary together. During the meeting:
- Each signer appears in a separate video feed.
- Only one signer can be the penholder at a time — the penholder is the only one who can sign or annotate, and the notary checks their ID during this time.
- Once all signers are in the waiting room, everyone joins the notary together. During the meeting:
- 5.Complete Your Part and Leave
- Once you've finished signing, the notary will lock the document as a saving mechanism. You can then leave the meeting on your own — wait for the notary to confirm before exiting.
Summary Checklist
- Signers join the same notary meeting from separate devices.
- All annotations must happen during the meeting — not before.
- If a signer proceeds without the others, the transaction converts to a split signing.
- Organizations can require all signers to be present before the meeting starts (compulsory concurrent signing).

Waiting Room for Meetings with Multiple Signers
The Waiting Room feature, available only to organizations with concurrent signing enabled, holds all multiple signers together after identity verification and before the notary joins, allowing them to start the meeting simultaneously or proceed with split signing if permitted, with real-time updates on signer arrivals and automatic connection to the notary once all are present.
Split Signing – Proof Help Center
Split signing is a process where multiple signers complete the same document individually in separate notary meetings—one at a time and in any order—either intentionally or automatically, ensuring each signer works from the most current document version, with the transaction only finalized once all listed signers have completed their portions.
Multiple-Signer Transactions Overview – Proof Help Center
Proof supports three types of multi-signer transactions—co-located (all signers together on one device), concurrent (signers in different locations joining the same meeting simultaneously), and split signing (signers in different locations meeting separately with a notary)—with each signer required to complete individual identity verification, the last signer paying all fees, and the option to mix notarized and e-sign-only signers within a single transaction.
Recipient Experience FAQs
The Business Pro plan on Proof supports multi-signer transactions through co-located signing (multiple signers together on one device), split signing (signers in different locations signing separately with separate fees), and concurrent signing (signers in different locations signing simultaneously in one meeting), requires individual identity verification for each signer, allows inclusion of representative signers, and supports various types of witnesses via the Notarize Network.
How Much Does Notarization Cost on the Proof Platform?
Proof Platform's notarization costs vary based on factors like the number of notarial seals, witnesses, and sessions, with standard fees including $25 for the first notary seal, $10-$15 for additional seals, witnesses, or signers, payment collected only after all parties complete signing and notarization, and pricing differing if documents are uploaded by the user or sent by an organization.
Send a Transaction to Multiple Signers – Proof Help Center
The Proof Help Center explains that multiple-signer transactions can be conducted via co-located, concurrent, or split signing methods, each with specific email address requirements—shared emails allowed only for co-located signers and unique emails required for concurrent or split signers—and provides detailed instructions on adding multiple signers during transaction setup, as well as guidance on correcting email address errors depending on the transaction status.
