# Faxing Legal Documents: Practical FAQ

Cover pages, confirmations, deadlines, and what to do if a court fax fails.

Do courts accept faxed documents?

Often yes, but rules vary by jurisdiction and document type. Always check local rules and any e‑filing requirements.

What should a legal fax cover page include?

Recipient, sender contact info, date/time, total pages, case/matter identifier, and a confidentiality notice when appropriate.

How do I prove I sent a legal fax?

Save the transmission/delivery confirmation and keep a copy of the exact PDF packet you sent (including the cover page).

What file format is best for faxing legal documents?

A clean PDF is best. Use black text on white background, readable signatures, and standard page sizes/margins.

What if my fax fails right before a deadline?

Retry during clerk/business hours if the line is busy, and call to confirm the correct number. For critical filings, use backup methods (e‑filing, in-person, or mail) as your court allows.

Can I fax legal documents internationally?

Yes—use the full international number format (with country code). See [international faxing](/blog/send-international-faxes).
