The short answer: If your document requires more than one signer, Proof offers three flexible signing methods to accommodate everyone involved. Each signer will need a valid photo ID, a U.S. SSN or ITIN, and a device with audio and video.
1. Signing Methods
2. Requirements for Each Signer
Each participant will generally need the following:
- Identity Verification: A U.S. Social Security number or ITIN for Knowledge-Based Authentication (KBA). If you don't have these identifiers, you may be prompted to use biometric selfie verification instead.
- Valid Photo ID: A government-issued ID for credential analysis.
- Contact Info: A U.S. address and a valid email address.
- Technology: A device with functional audio and video capabilities.
3. How to Get Started
1. Upload and Invite
Upload your document here to begin. Enter your email and create a password to get started.
2. Add Signers
When asked who needs to sign, select Multiple People. Then provide the email addresses for all additional signers. You can click Add Another Signer to include everyone involved.
3. Signers Receive Invitations
Each signer will receive an automated email with a unique link to access and complete the document.
4. Payment and Completion
To keep things simple, the last signer pays the total transaction fees at the end of the final session. This ensures that fully notarized documents are released to all parties immediately upon completion.
