What is a burofax and how does it work?
A burofax is a certified document delivery service that authenticates the content of a communication, together with the sender’s identity, the recipient’s identity, and the exact date of dispatch. It creates a verified paper trail that courts accept as evidence.
Many people assume a burofax involves a fax machine — the name is misleading. All you actually need to send one is the recipient’s postal address. The service is handled by Spain’s national postal operator, Correos, which guarantees and certifies every step of the delivery process.
A burofax carries evidentiary weight before the courts. Because every element of the communication is officially authenticated — content, sender, recipient, and date — it can be submitted as formal proof in legal proceedings.
When should you send a burofax?
Send a burofax whenever you need to certify that a communication was made and that its content is exactly what you say it is. The goal is not just to deliver a message — it is to create a legally recognised record that you made that communication on a specific date.
Burofaxes are most commonly used to file formal complaints or demands, whether addressed to an individual or a company. Sending one demonstrates that an attempt to communicate was genuinely made — something a standard letter, email, or phone call cannot prove.
Typical situations where a burofax is the right choice include unpaid invoices, traffic-fine disputes, construction defect claims, insurance policy terminations, and consumer organisation complaints against telecoms or utilities — any scenario where having certified proof of your communication matters.
What must a burofax contain to be legally valid?
Most burofaxes are sent in anticipation of legal proceedings. Although anyone can draft and send one, we strongly recommend working with a qualified lawyer who can advise you throughout the process.
If the matter goes to court, the burofax may become central evidence. Having a lawyer draft or review it gives you far greater confidence that it has been prepared correctly — and gives it real weight as a legal instrument.
A burofax signed by a lawyer carries considerably more authority than one sent by a private individual. That psychological and procedural weight is itself a practical advantage worth considering.
If you choose to draft the burofax yourself, make sure it always includes the following elements:
The burofax must clearly identify the sender and the recipient. Always include the full name, surnames, and national ID number (or company registration details) to avoid any ambiguity.
It must be signed by the individual sending it — or, if sent on behalf of a company, bear the company’s official seal.
If delivery was unsuccessful, the burofax must state the reason why it could not be delivered and the circumstances that prevented it.
The document must also include the date the communication was processed, along with the details of any trusted third parties — such as the postal operator — who handled or certified the delivery.
How much does it cost to send a burofax?
Sending a burofax is not cheap. At a Correos post office, a single-page burofax starts at around €7. The price can rise to approximately €25 if you add an acknowledgement of receipt and delivery confirmation — both of which are worth paying for if you need watertight evidence.
Cheaper communication methods exist, of course. But no other channel gives you the certified evidentiary value of a burofax. In situations where proof of communication matters, the cost is rarely the deciding factor.
What happens if the recipient does not respond to a burofax?
Ignoring a burofax is not a viable strategy for the recipient. Correos is required to make two delivery attempts. If nobody is present, a notification slip is left instructing the recipient to collect the document from their local post office.
Crucially, established case law in Spain holds that failing to collect or receive a burofax — for whatever reason — does not prove the recipient was unaware of its existence. The notification obligation is considered fulfilled once delivery was genuinely attempted.
This is one of the most important practical advantages of the burofax: the sender’s legal position is protected even if the recipient refuses to engage.
Time limit for replying to a burofax
The deadline for responding to a burofax should always be stated within the document itself. The standard practice is to allow 7 working days. If you intend to use the burofax as evidence in court, leaving the response deadline undefined undermines your position.
Setting an unreasonably short deadline — a few hours, for instance — risks making the document look coercive and could reduce its authority before a judge. A reasonable timeframe strengthens both the communication and your legal standing.
Burofax vs registered letter: what is the actual difference?
The critical difference comes down to evidentiary value before a court.
Both services notify the sender once the item is delivered. However, a registered letter only confirms that something was delivered — it says nothing about what was inside it. The recipient could claim the envelope contained blank pages and there would be no way to disprove it. A burofax eliminates that risk entirely: its content is authenticated at the point of sending, not just at the point of delivery.
Burofax in the context of online reputation and data protection
A burofax is also a recognised tool for formally requesting the removal of harmful content, fake reviews, or personal data from websites and platforms. When sent to a website operator, platform, or data controller, it creates a certified record of the request — establishing a clear timeline that strengthens any subsequent legal action, including a complaint to the ICO (Information Commissioner’s Office) under the UK GDPR and the Data Protection Act 2018.
Under the UK GDPR and the Data Protection Act 2018, individuals have the right to request erasure of their personal data. A burofax addressed to the data controller creates a timestamped, court-admissible record that the request was made — which is critical if the controller fails to comply within the statutory one-month response period. If you are dealing with online content that damages your reputation, professional help speeds up the process considerably: specialist legal and reputation management services know exactly which channels to use and when.
Burofax: common legal questions answered
What makes a burofax legally valid as evidence?
A burofax is legally valid as evidence because the postal operator certifies three things simultaneously: the identity of the sender, the exact content of the document at the moment of sending, and the date and time of the communication. Unlike an email or a standard letter, the content cannot later be disputed — it was authenticated before it left your hands. Courts in Spain routinely accept burofax certificates as admissible evidence.
Can I send a burofax without a lawyer?
Yes, any individual or company can send a burofax without legal representation. However, if you anticipate that the matter may reach a court, having a lawyer draft or review the document is strongly advisable. A lawyer-signed burofax carries more weight procedurally, and an expert can ensure the wording creates the exact legal effect you need rather than inadvertently weakening your position.
What happens if the recipient refuses to collect the burofax?
If the recipient does not answer the door on either of the two delivery attempts, Correos leaves a collection notice at their address. If the document still goes uncollected, Spanish case law treats the recipient as having been notified — the legal effect of the communication is not neutralised by the recipient’s refusal or absence. The sender’s position is protected regardless.
How much does it cost to send a burofax, and are there cheaper alternatives?
A single-page burofax starts at around €7 at a Correos office. Adding an acknowledgement of receipt and delivery notification can push the total to approximately €25. While that is more expensive than email or a standard letter, no other channel provides the same certified evidentiary value. In legal or pre-legal situations, the cost is almost always justified.
Can a burofax be used to request the removal of content from a website?
Yes. Sending a burofax to a website operator, hosting provider, or data controller to request the removal of harmful content or personal data creates a certified, timestamped record of your request. This is useful both as a direct formal demand and as documentary evidence for any follow-up complaint to a data protection authority — such as the ICO in the UK or the AEPD in Spain — if the controller fails to act within the required timeframe.
Is a burofax the same as a registered letter?
No. The critical difference is that a registered letter only confirms delivery — it says nothing about the content. The recipient could later claim the envelope contained blank pages, and you would have no way to disprove it. A burofax authenticates both the delivery and the content at the moment of sending, making it far stronger as legal evidence.
