Fax and proof: one method for seven countries
Similar rules, different formalities.
Across Faxeroo's seven destinations, no legal system rules out fax as evidence, and none accepts it automatically in place of a signed original. European and Canadian law alike follow the same pattern: distinguish what a court admits from what convinces, and judge a copy by its fidelity. The formalities are what change: the monetary level above which a signed document becomes mandatory, the definition of “written form”, the notary's monopoly over certain acts. This page does not deliver a verdict per country; it gives you reference points and shows where to read the texts.
The common foundation of the seven destinations
Admissibility and weight are not the same thing. Germany reasons in terms of free assessment of evidence (§ 286 ZPO), Spain in terms of the judge's “valoración”, Italy and Portugal in terms of reproductions that the opposing party can challenge on the ground that they are not faithful. The vocabulary differs, the pattern holds: merely sending a fax offers no assurance that it will carry conviction.
It is the formalities that separate the countries. Belgium: Book 8 of the Civil Code, applicable since 1 November 2020, in principle requires a signed writing for any act of at least €3,500 proved against an individual. Germany: under § 126 BGB, “Schriftform” demands a signature written by hand in the original — something a fax transmission lacks. And everywhere, real property passes through a notary. First question: is the act you are faxing subject to a required form?
Fidelity decides the fate of a copy. The Portuguese Código Civil (art. 368) and the Italian Codice civile (articles 2712 and 2719) alike give mechanical reproductions their full effect until their accuracy is challenged; in Quebec, the Civil Code governs technological documents from article 2837 onwards. From one country to the next, your best asset does not change: the original kept, and the time-stamped record of the dispatch.
Four checks before sending
Name what you are sending
Purchase order, notice, complaint, supporting document: each document has its own regime. Establish its legal nature and the cost of a contested send first; the choice of channel comes after.
Go to the official source
Each state puts its consolidated legislation online for free. The table points to the official portal and the codes carrying the rules of evidence. Those texts take precedence over summaries found online, which frequently turn out to be outdated or drafted with a different jurisdiction in mind.
Spot the treatment of copies
That is what governs fax, along with the rules on electronic documents. Also check whether the law separates individuals from businesses: several countries relax the requirements between traders.
Ask the recipient
Court registry, government office, insurer, supplier: each imposes its own procedures, sometimes stricter than the law. One question — “will this document be accepted by fax?” — saves you a refusal at the counter.
Where to read the texts: portals and codes

The right contact, depending on the stakes
For an ordinary send — invoice, form, supporting document — the rule comes from the recipient. Ask them to tell you the format they accept and the number to dial. Their answer counts for more than an abstract analysis: they are the ones who will open your document.
When the send creates or preserves a right — a notice, a dispute, a declaration on a deadline — take advice from a lawyer, or a notary, in the country with jurisdiction. The gap between admissible and convincing comes with a price tag there, sometimes with lost deadlines.
Proof by fax abroad: your questions
- Does Europe have a common rule on the value of a fax?
- No. The eIDAS regulation governs electronic signatures and trust services; the strength of a fax remains a national matter. What Lisbon accepts is not guaranteed on the same terms in Munich.
- Each country in one sentence: why not?
- One sentence cannot capture the distance between a notice, a contract and a mere annex, or the effect of successive reforms. Condensing it would give false certainty, on ground where mistakes are costly. We prefer to hand over the texts and the method.
- My fax leaves France for abroad: which law applies?
- Admissible evidence follows, as a rule, the court seized and, on certain points, the law that governs the act. That said, many contracts pick their own court and their own law: reread those clauses, the answer is often there.
