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.
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.
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).
