The short answer: Co-located signing is for transactions where all signers are physically together and share one device to use Proof. Each signer must separately complete identity verification. For other multi-signer transaction types, see Multiple-signer transactions overview.
Setting Up the Transaction
Signers Initiate Their Own Transaction
- Each signer uses their own email address.
- Only 2 co-located signers are supported on mobile. For more than 2, start on a computer.
- Some signers may be required to join from a separate device — Proof will indicate this if it applies.
Organization Sends the Transaction
- Each signer receives their own invitation email at their own email address.
- When a signer opens their invitation, they'll be prompted to indicate whether they're signing together or joining from a separate device.
- Signers can use any device to complete the transaction, regardless of how many signers are present.
Complete the Transaction
1. Start the Process +
Open the email from Proof and select the button to begin. The Proof site opens — select Notarize Now to continue.
2. Select the Signers +
Confirm all signers are physically present and sharing the same device, then select Continue.
For organization-sent transactions: the signer who initially opens the email is automatically selected and must be present before moving forward.
3. Review the Documents +
Review the documents before joining the notary meeting. If you spot an error in the document content, select Report a Document Error to flag it.
4. Verify Identities +
In some cases, you'll receive a code via email and must enter it before continuing. Each signer then completes identity verification separately.
5. Join the Meeting +
Grant the Proof website permission to access the camera and microphone, then select Join Now to enter the meeting and complete the transaction.
