Demanding unpaid rent in Spain: why the method and the 30 days matter

If you demand payment by a reliable means at least 30 days before suing and the tenant does not pay, they can no longer stop the eviction by paying during the case. That demand goes by certified burofax or notary; a carta certificada is right for the first reminder.

Do you need a burofax to claim unpaid rent?

For the 30-day demand the law asks for a reliable means (medio fehaciente): one that proves delivery and what the letter said. That is why landlords use a burofax with certified content or a notary.

A carta certificada (Spanish registered letter) proves delivery, the date and a signature, not the text. Use it for the first reminder and to propose a payment plan: it proves the tenant received it, and when. See what each one proves.

What should you know before suing?

  • If the tenant already stopped an earlier eviction by paying, they cannot do so again, unless payment failed through your fault.
  • Most civil claims require an attempt to negotiate first, with proof the tenant received your proposal and could read it. Put it in the same certified burofax as the demand and one letter covers both.
  • If the tenant proves financial hardship, the authorities have two months to offer housing or pay the debt. The October 2026 rental rules come from decree-laws that the Spanish parliament still has to ratify. An earlier text was repealed in September: on the day you send, check the version in force in the BOE, Spain's official gazette.

Frequently asked questions

Must a Spanish rent demand go by burofax?

For the 30-day demand the law asks for a reliable means. A burofax with certified content or a notary meets it.

Is a carta certificada enough?

It proves delivery and the date, not the text. It suits the reminder and the proposal to settle.

What does the landlord gain from the demand?

If the tenant has not paid when the claim is filed, they can no longer stop the eviction by paying in court.

Do I need to negotiate before suing?

Yes, for most civil claims. The same letter can demand payment and propose an agreement.

What if the tenant does not reply?

30 calendar days after receiving your proposal, the negotiation counts as ended without agreement.
