Rights and deadlines

Tenants have basic rights regarding habitability, rent payment and opposition to abusive increases. Consult the applicable legislation for deadlines to oppose and formal procedures[1]. Note all dates: payment deadlines, receipt of notices and hearings are decisive to preserve your rights.

In many situations tenants are entitled to minimum habitability standards.

Negotiate an amicable agreement

Before starting judicial action, try a written agreement that clarifies amounts, deadlines and each party's responsibilities. A written agreement facilitates enforcement if the landlord fails to comply.

  • Communicate in writing: send proposals and responses by registered letter or email and keep copies.
  • Gather evidence: photos, rent receipts, messages and witnesses that prove the agreement and breaches.
  • Propose mediation or conciliation before starting enforcement to reduce costs and time.
Document all communications in writing and keep copies.

When to proceed to enforcement

If the agreement is not fulfilled, you can request enforcement of enforceable titles or initiate collection/eviction proceedings depending on the case. Use official forms and procedures when available to speed up the process[2]. Assess costs, deadlines and the need for legal assistance before proceeding.

Respond to notices within the indicated deadlines to avoid losing rights.

How to file a complaint and use forms

Here are practical steps to file a formal complaint or enforcement request with the competent authorities:

  • Identify the appropriate procedure (complaint, rent reduction request, enforcement of title).
  • Complete the official forms carefully and attach relevant evidence such as contracts and receipts.
  • Submit the complaint or request through the indicated channels (Citius/Balcão) and keep proof of submission.
Detailed documentation increases the chances of success in a dispute.
