How it works

1. Draft

   Describe your situation to ChatGPT in English and it drafts the letter in Spanish. Ask it for an English translation to check the wording. Or paste your own text.

2. Check

   You see the exact PDF, with pages counted and a fixed price. Choose a Correos burofax or a certified notification, and pay by card.

3. We send it

   It goes out within 24 working hours. Follow it on your tracking page and download the proof of delivery and certified content as they arrive.

Two ways to send it

The Correos burofax is the best-known format in Spain. The certified notification costs half as much and also proves content and delivery. It is not a Correos burofax: Notificados, a trusted third party, sends and certifies it. If the other side or a court expects a burofax, choose Correos.

Written in English, sent in Spanish

• The letter goes in Spanish

  It should be in Spanish, or bilingual with the Spanish first, so the recipient and, if it comes to it, a Spanish court can read it.

• ChatGPT drafts the Spanish

  Explain your situation in English and ChatGPT drafts the letter in Spanish. Ask it for an English translation to check every line before you approve it.

• Send it from anywhere

  With us you don’t need to visit a Spanish post office, or have Cl@ve (Spain’s government login) or a Spanish phone number. You need the recipient’s address in Spain, an email address and a card.

• No Correos account

  You don’t sign up at correos.es or lay out the document yourself. We turn your text into a PDF, you check it, and we send it.

• Proof you can keep

  The acuse de recibo (proof of delivery) shows when it was delivered and to whom. The certificación de contenido (certified content) shows what it said. Both come as PDFs.

• If nobody is home

  Correos leaves a notice and the letter waits at the post office. If it isn’t collected or is refused, the proof of delivery records that, which shows you tried.

What people send by burofax

Anything where you may later need to prove you gave notice. What a burofax is, and what it proves. Thinking of UK recorded delivery instead? Compare it with a burofax.

• Getting a deposit back

  If your landlord hasn’t returned the deposit (fianza) a month after you hand back the keys, the amount owed starts to earn statutory interest (Tenancy Act, LAU, art. 36.4). A burofax records that you asked for it, and when, even after you have left Spain.

• An unpaid invoice

  A dated demand for payment to a Spanish client, before you take it further.

• Cancelling a contract

  A phone, gym or insurance contract that keeps billing you. The burofax proves that you cancelled, and when.

• Notice to a tenant

  Non-renewal or a demand for unpaid rent, sent by a non-resident owner.

• Community and neighbours

  Writing to the comunidad de propietarios, its administrator or a neighbour, with proof of delivery.

• Before going to court

  Since 3 April 2025, most civil claims in Spain can only be filed after an attempt to negotiate (article 5 of Organic Law 1/2025). A burofax proves that the other side received your proposal, and when.

Questions

Is a burofax legally binding?

A burofax doesn’t oblige anyone to do anything by itself. It serves as evidence that you sent it, of what it said and of when it was received, and that evidence comes from Correos, which is not a party to the dispute.

What effect it has depends on your case. If you are in a dispute, talk to a qualified professional in Spain.

How long does delivery take?

We send it within 24 working hours of payment. After that, Correos says it normally delivers a burofax within 24 working hours at most. Every status change appears on your tracking page.

How many pages can I send?

The price includes up to 3 pages. Each extra page costs €3.00 for a Correos burofax and €2.00 for a certified notification, up to 10 pages. A bilingual letter takes roughly twice the space.

Can I attach documents?

Not yet. We send text letters. Refer to your documents in the letter (contract date, invoice number, amounts) and keep the originals.

Can I write the letter in English only?

We can send it, but the letter should be in Spanish, or bilingual with the Spanish first, so the recipient and, if it comes to it, a Spanish court can read it. In English alone, the recipient can say they didn’t understand it.

Do you check my letter?

We check that it is ready to send: complete recipient details, page count and layout. We don’t judge whether the content is enough for your case. We are a sending service, not a law firm.
