Burofax or carta certificada: what each one proves

A carta certificada (Spanish registered letter) proves your letter arrived, when, and who signed. A burofax with certified content also proves what it said. If nobody will dispute the text, the carta certificada is enough.

When is a carta certificada enough?

When what you must show is that you gave notice in time: cancelling insurance, giving notice on a flat or telling the community of owners your address. In those cases the law asks for written notice or a method that proves receipt, and a carta certificada meets it.

Use a burofax with certified content when the other side could deny what the letter said and that decides the outcome, for example a demand for unpaid rent before an eviction. Correos sells it at its offices and online.
