Signing documentation
Prepare a PDF for signing
Check the final document, file size and intended signers before creating a BL Sign envelope.
Review the final file
BL Sign accepts PDFs up to 15 MB. Open the final file and check every page, page order and any fields that must already be completed. Keep a copy of the exact input so later revisions do not get confused with the signed version.
Confirm the participants
An envelope supports up to eight sequential signers. Confirm the recipients and intended signing order before starting. The signer does not need an account.
- Check the final PDF and page order.
- Confirm recipient details and sequence.
- Identify any separate filing or notarization requirement.
Separate preparation from completion
Creating an envelope begins the workflow. Completion requires the intended signer actions and the resulting completed document and signing record.
