Why Legal Professionals Still Rely on Fax
Unlike email, fax has unique legal standing in many jurisdictions:
- Court filings: Many state and federal courts accept faxed filings for time-sensitive motions, especially after-hours emergency filings. Some courts require fax for certain document types.
- Legal presumption of delivery: A fax transmission confirmation creates a rebuttable presumption of receipt in most U.S. jurisdictions — stronger legal standing than email read receipts.
- Opposing counsel communication: Serving discovery documents, settlement offers, and cease-and-desist letters by fax is standard practice and creates a reliable paper trail.
- Notarized documents: Notaries routinely fax apostilles, notarized affidavits, and acknowledgments to government offices, foreign consulates, and title companies.
- Real estate closings: Title companies, lenders, and escrow agents exchange signature pages, title commitments, and closing instructions by fax daily.

Best Practices for Legal Faxing
- Always use a cover page: Include matter name, client ID, confidentiality notice, and intended recipient. Fax.plus auto-generates cover pages from your email subject line.
- Verify fax numbers before sending: A misfaxed privileged document can waive privilege. Double-check court and opposing counsel fax numbers.
- Save delivery confirmations: Download and store fax confirmations in your case management system. These serve as proof of service in many jurisdictions.
- Use PDF/A format: For archival documents, use PDF/A — it preserves formatting across systems and is court-approved.
- Enable two-factor authentication: Protect your fax account with 2FA. Fax.plus supports TOTP authenticator apps.
