Summary
Yes, a French judge can take it into consideration. The law of evidence rules out no channel: whether the document leaves an office machine or a website changes nothing. What remains is knowing what the piece is worth — the transmission receipt establishes that a line was opened to a stated number at a logged time, but says nothing about what the pages contained or whether anyone read them.
Admissible, then assessed
All forms of evidence are permitted, as Article 1358 — part of the Civil Code — makes clear, unless a statute rules otherwise. In dealings between businesses, the Commercial Code's Article L110-3 accepts every means. Once a ceiling fixed by decree (€1,500) is crossed, Article 1359 demands a written record of the legal act; a fax on its own then serves, at most, as an early stage of written proof (Article 1362).
The origin of the fax, office machine or online service, does not alter its treatment. The judge then assesses the piece on the merits: a fax remains a copy, all the more convincing for fitting into a coherent file.
What the transmission receipt proves
With the €2.99 including VAT option, two PDFs come back to you: one for the request, the other for the transmission. This second document timestamps the connection, identifies the number called and totals the pages passed. The printed text, the hand that collected the sheets: none of that appears there.
Keep it alongside the very PDF dispatched, together with the surrounding exchanges — reminders, responses, phone calls logged as they occur. How the law treats fax across Europe lays out the rules nation by nation.
When the fax no longer suffices
A cancellation that requires registered mail with advice of delivery, an act that demands an original signature, or service by a bailiff: in these cases, the fax informs but does not replace the formality. Check what your contract or the governing law actually demands, then pick the channel.
Key points
- Proof is free in principle: the fax can be added to the file.
- The receipt dates the connection, points to the number and counts the pages.
- Content and reading are not deduced from the receipt.
- Some formalities require registered mail or the original.
