Challenging enforcement and agreements for tenants Portugal

Dispute resolution & rent reduction 2 min read · published September 11, 2025
If you are a tenant in Portugal and received an enforcement notice or were invited to sign a friendly agreement, this guide explains in practical terms how to challenge decisions, appeal and protect your rights. You will find guidance on procedural deadlines, which evidence to gather, how to communicate with the landlord and when to seek official help. We also describe the steps to follow when filing a request at the Tenant and Landlord Desk or in court, and what to expect during a hearing. We avoid technical language where possible and give tips to keep documents organised, contact public services and prepare a clear defence if the process advances.

What does it mean to challenge and to appeal?

To challenge means to dispute the validity of a procedural act, for example an eviction enforcement; to appeal is to ask a higher court to review a decision. As a tenant, you can use both to protect rights related to rent, notices or contract clauses. Learn which deadlines apply and when to seek legal or administrative support, including the Tenant and Landlord Desk.[2]

Keep copies of all communications with the landlord.

Documents and evidence to gather

  • Contracts and amendments.
  • Rent receipts, payment receipts and bank statements.
  • Photos and videos showing damages or the housing condition.
  • Exchanges of messages, notices and letters between tenant and landlord.
  • Relevant deadlines and payment schedules.
Well organised documentation makes defence easier in court or administrative procedures.

How to challenge — basic steps

If you receive an enforcement petition, read it carefully, calculate opposition deadlines and request copies of all evidence. In many cases it is possible to submit a written opposition or negotiate a friendly agreement; if you accept an agreement, check terms and consequences before signing. Applicable law includes the NRAU and the Civil Code, which define tenant rights and duties.[1]

Respond within deadlines to avoid losing the right to challenge.
