Can I send a burofax from my own post office?

No. It is a Spanish service and is sent from inside Spain. From abroad you send it online and it is printed and delivered in Spain.

Can I attach documents?

Yes: the contract, invoices or photos go in the same burofax and count as pages. Up to 4 pages are included; each extra page is 1 €.

What does the notary add?

A notary certifies the exact text that was sent. It is the strongest proof of content and costs 35 € more for up to 3 pages. You can ask for it when paying or years later.

Does my signature need to be on it?

No. The letter identifies you with your name and ID number. On paper a digital signature does not survive printing.

From outside Spain · registered letter

How do I send a registered letter to Spain that proves what it said?

Send it as a burofax, from inside Spain. An international registered or signed-for letter only proves that an envelope arrived; a burofax also keeps a record of the letter itself, which is what you need if the other side later denies what you told them. You do it online from any country for 39 € with your own letter, and it is delivered in Spain the next working day.

Content: a copy of the exact letter is kept for 10 years
Next day: instead of a week or more by international post
39 €: your letter, sent from abroad

I have my letter, 39 €

What each option proves

Email: that you sent it. Not that they received or read it.
International registered or signed-for post: that an envelope was delivered and who signed. Not what was inside, and tracking often stops at the border.
Courier: the same as registered post, faster.
Burofax: that it was sent, the date it was delivered or delivery was attempted, and the content of the letter.

Why the content matters

The usual defence is not “I never got it” but “that letter didn't say that”. Spanish law asks you to prove that the other party could read the full content of what you sent. With a burofax the operator keeps a copy of your letter for 10 years, and a notary can certify the exact text when you pay or at any time later.

How to send it from abroad

Paste your letter or upload it as PDF or Word. We tell you for free if something is missing.
Enter your details. If you have no address in Spain, tick the box (+10 €): it goes out in your name «c/o Burofácil», with our Spanish address on the envelope only.
Enter the recipient's name and address in Spain (not a PO box).
Pay by card, Apple Pay or Google Pay. If it goes out before 18:00 Spanish time on a working day, it is delivered the next working day.
We email you the proof that it was sent and the proof of delivery, or of the delivery attempt.

Paper, certified email, or both

Paper with proof of delivery is the default. If you have the recipient's email, you can send it by certified email at the same price: they open the letter with a code, and what was sent, when it arrived and whether they opened it are all certified. Both together cost 10 € more and give you two proofs.

If the recipient is out or won't take it

The postman tries twice, on different days, and then the letter waits 10 days at the post office. If they refuse it or never collect it, the operator certifies the attempt with its date. Many Spanish courts accept that as proof that you tried, but not all see it the same way, so if it happens send it again to another address or by certified email.

What Spanish law says

The attempt is proved with a document showing that the other party received the proposal, the date, and that they could read its full content; with no reply in 30 calendar days it ends without agreement (arts. 10.2 and 10.4 Organic Law 1/2025). fuente
The letter can go to the address or workplace you know for the recipient, or to the electronic channel you used with them (art. 7.1 Organic Law 1/2025). fuente
