How to Fax Legal Documents Online — Securely, Without a Subscription

Legal documents often require fax because the transmission log serves as a verifiable record of delivery — something email does not provide in the same way. Law firms, courts, real estate agencies, banks, and insurance companies all still exchange legally sensitive paperwork by fax as a matter of standard practice.

If you need to fax a contract, court filing, mortgage document, insurance form, or other legal paperwork, you do not need a fax machine or a monthly subscription. An online fax service lets you upload a PDF, enter the recipient's fax number, and receive confirmation of delivery.

Why legal professionals still use fax

Several properties of fax make it persistently useful in legal and regulated contexts:

Point-to-point delivery: A fax goes directly from sender to recipient's machine. There is no intermediate server that routes, stores, or scans the content for advertising or training purposes — a critical distinction from many email services.
Delivery confirmation: The sender receives a transmission report when the fax is successfully received. This confirmation — along with the date and time — can be used as evidence that a document was delivered by a specific time.
Court and agency acceptance: Many courts, regulatory bodies, and government agencies specify fax as an accepted submission method in their procedural rules, particularly for time-sensitive filings where proof of receipt on a specific day matters.
Signed document integrity: A scanned PDF of a signed document faxed to the recipient creates a physical record on their end, which in many jurisdictions is treated as equivalent to a mailed copy.

Before you send: how to prepare your legal document

The quality of a faxed legal document depends almost entirely on the quality of the PDF you upload.

Check the following before uploading:

All signatures are present and legible. A digital signature, wet ink scan, or typed signature block should be clearly visible — not cut off, not overlapping with text.
The document is not password-protected. Protected PDFs cannot be processed by an online fax service. Remove the password in Adobe Acrobat, Preview (macOS), or any PDF editor.
Margins are adequate. Fax machines print with standard margins. Text or signatures too close to the edge may be cut off on the receiving end. A safe margin is at least 10mm on all sides.
The font is readable at standard size. Fine print in 6pt or smaller may not reproduce clearly through fax. If the document requires initials or acknowledgement of specific terms, make sure those sections are large enough to read.
The page count is correct. Review every page before uploading. A missing page in a contract can create disputes later.

Step-by-step: fax a legal document online

1. Export or scan your document to PDF

If your legal document is in Word or another format, save it as PDF first. For signed paper documents, use a flatbed scanner or a scanning app on your phone to produce a clean PDF (not a blurry photo).

2. Upload to Send Fax Online

Go to Send Fax, upload your PDF, and let the service count the pages. You can preview the fax before paying.

3. Enter the recipient's fax number

Select the destination country and enter the full local fax number. For legal submissions, the fax number is often listed in the court's procedural guide, the opposing counsel's letterhead, or the agency's website. Use the exact number — do not assume a phone number can receive faxes.

4. Confirm and pay per page

At 10 credits per page, a standard 5-page contract costs 50 credits. Credit packs start at $4.99. There is no subscription or ongoing plan.

5. Save your delivery confirmation

Once the fax is delivered, the status in your fax history updates to Delivered. Keep a record of the delivery status and timestamp, especially if the fax is tied to a legal deadline or filing window.

When to keep a paper backup

An online fax delivery record is useful, but for high-stakes legal submissions, best practice is to retain:

A copy of the PDF you sent (saved to your own files)
A screenshot or export of the delivery confirmation
The fax number you sent to, with the date and time

If a deadline dispute ever arises, your delivery record and the timestamp are your evidence.

Fax vs email for legal documents

Criterion	Fax	Email
Delivery confirmation	Timestamped transmission record	Read receipts optional and unreliable
Accepted by courts	Often explicitly specified in procedural rules	Varies; courts may reject email submissions
Interception risk	Point-to-point, no intermediate server	Passes through multiple servers
Document storage	Printed on recipient machine	Stored in cloud inboxes indefinitely
Evidentiary standard	Widely recognised in many jurisdictions	Still evolving in many legal contexts

Does online fax meet legal delivery standards?

It depends on the jurisdiction and the specific filing requirement. In most common law countries — the US, UK, Canada, Australia, Singapore — fax is explicitly recognised in procedural rules as a valid method of service and submission. An online fax service sends the document through the standard fax network, so the receiving party's machine receives it as a conventional fax transmission.

If you are unsure whether an online fax service is acceptable for a specific court or regulatory filing, check the relevant procedural rules or consult the receiving party's office directly.

FAQ

Is a faxed signature legally binding?

In most jurisdictions, yes. A faxed copy of a signed document is generally treated the same as a fax of any other document. The legal weight of the signature itself depends on your jurisdiction and the type of document. For contracts where electronic signatures are acceptable, a PDF with a valid electronic signature faxed to the counterparty is typically enforceable.
