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 attests that a connection took place, to a specific number, at a specific instant; the content of the pages and their reading cannot be deduced from it.
Admissible, then assessed
Every mode of proof is admissible, states article 1358 of the Civil Code, unless a provision says otherwise. Between traders, article L110-3 of the Commercial Code admits all means. Beyond a threshold set by decree (€1,500), article 1359 requires a written document to record a legal act; an isolated fax then counts at best as a start 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.
File it with the exact PDF sent, plus the neighbouring exchanges — follow-ups, replies, calls noted as they happen. The European overview of the legal value of fax sets out the framework country by country.
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. Re-read the contract or the applicable text before choosing 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.
