Deadlines for Tenants at BNA in Portugal

Landlord termination, protection & eviction (BNA) 3 min read · published September 11, 2025

As a tenant in Portugal, knowing the deadlines to start an application at the Tenant and Landlord Desk (BNA) is crucial when facing a notice, risk of eviction or protection issues. This guide explains, clearly and practically, when and how to act: deadlines for filing complaints, notices to receive, essential documents and available provisional measures. It also shows where to get official forms and how to prepare evidence to support the application. You do not need to be a lawyer to follow these steps; the goal is for any resident to understand legal timing, avoid losing rights through delay and make informed decisions about responses, agreements or court actions.

What the BNA is and legal basis

The Tenant and Landlord Desk (BNA) is a mechanism to handle tenancy disputes and requests for urgent measures. In many cases the application uses NRAU and Civil Code provisions as a basis for protection and suspension of acts, so it is important to know the legal deadlines.[1]

Main deadlines

  • Deadline to contest a notice: check the notification and act immediately, as deadlines can be short.
  • Deadlines to request provisional measures at the BNA: these are often urgent and require rapid submission of evidence.
  • Response times to notices: comply with the deadlines indicated in the letter or summons to avoid losing rights.
Respond to notices within the deadlines to avoid losing rights.

Documents and evidence that speed the process

  • Tenancy agreement and rent receipts: essential proof to show the contractual relationship.
  • Notifications and communications received from the landlord: keep dated copies.
  • Photos, messages and contact records that prove lack of maintenance or attempts to agree.
Clear, chronological documentation facilitates quick decisions by the BNA and the courts.

If you need official forms to file the application at the BNA, check the available templates and submission locations on the competent judicial platforms.[2]

What to expect after filing the application

After submitting the application, the BNA or the court may request clarifications, schedule a hearing or decide on provisional measures. Deadlines for each stage vary: some urgent requests are reviewed in days, others require weeks. Keep in touch with the services and compile responses to any requests for additional documentation.
