Why legally-binding PDFs matter

Creating legally binding documents efficiently is critical. Traditional methods such as printing, scanning, faxing, or emailing PDFs, are slow, prone to errors, and risky. Missing signatures, lost audit trails, or misplaced documents can cause compliance issues, delayed deals, and business disruptions. Secure, signable PDFs streamline workflows while ensuring documents are enforceable under law.

What makes a PDF legally-binding?

For a PDF to be legally binding, it must meet certain requirements:

  • Intent to sign: All parties must clearly intend to sign the document.
  • Consent: Signers must voluntarily agree to the terms.
  • Signature authentication: The signature must be verifiable and attributable to the signer.
  • Integrity of the document: Any changes after signing must be detectable.
  • Compliance with applicable laws: Including e-signature laws like ESIGN Act (U.S.) or eIDAS (EU).

Legally binding PDFs also benefit from audit trails, role-based signing, and secure storage.

How to create legally-binding signable PDFs

Method 1: Using PandaDoc UI

  1. Log into your PandaDoc account.
  2. Click “Documents” > “Create New”.
  3. Choose “Upload” and select your PDF (or use a pre-made template).
  4. Assign roles (who needs to sign or fill out the document).
  5. Drag and drop fields onto the PDF (Signature, Date, Text, Checkbox, etc.).
  6. Assign each field to a specific recipient.
  7. Add optional settings: expiration dates, reminders, or password protection.
  8. Send the document for signature.
  9. Monitor document status (Viewed, Completed, etc.) via the dashboard.
  10. Download or archive the signed PDF when complete.

This method is ideal for one-off documents or when you want a simple, no-code workflow.

Method 2: Using PandaDoc API

  1. Authenticate via OAuth2 to access the PandaDoc API.
  2. Use POST /documents to create a document with your PDF file.
    • Include: name, uploaded file (file_url or file), and recipients’ info.
    • Optionally use templates to pre-define fields, or define fields in the request using fields.
    • Assign roles to recipients (signer, viewer) in the payload.
  3. Send the document by setting send_email=true (or send separately using POST /documents/{id}/send).
  4. Use GET /documents/{id} to check status (e.g., uploaded, sent, completed).
  5. Use GET /documents/{id}/download to retrieve the signed PDF.
  6. Use webhooks to automate updates on document status (e.g., signed, expired).

API workflows are ideal for high-volume, dynamic documents or for deeper integrations with CRM/ERP systems.
