How to File Insurance Complaint with Portugal ASF

When a private insurer in Portugal refuses to honour a claim and your internal complaint has failed, the Autoridade de Supervisão de Seguros e Fundos de Pensões (ASF) is the regulatory body with the power to investigate and apply pressure. Understanding the full process — from the mandatory Provedor do Cliente step through to ASF and beyond — gives you the best chance of recovering your denied benefit.

What Is ASF?

The Autoridade de Supervisão de Seguros e Fundos de Pensões (ASF) is Portugal's independent insurance and pension fund regulator, established under Decree-Law No. 1/2015. ASF supervises all insurance companies authorised to operate in Portugal — including Portuguese insurers like Fidelidade, Médis, and Tranquilidade, as well as EU-based insurers providing services into Portugal.

ASF's mandate includes:

• Licensing and supervising insurance companies
• Ensuring financial soundness of insurers
• Protecting policyholders and beneficiaries
• Investigating complaints about insurer conduct

• Telephone: 21 790 3100
• Email / Online complaint form: asf.com.pt → "Consumidores" → "Reclamações"

What ASF Can and Cannot Do

ASF CAN:

• Investigate whether your insurer violated Portuguese insurance law (Decree-Law No. 72/2008 — the Insurance Contract Regime — and related ASF regulations)
• Require your insurer to respond and provide full documentation
• Issue supervisory sanctions including fines, warnings, and activity restrictions
• Facilitate early resolution through regulatory inquiry
• Publish supervisory decisions, creating reputational accountability

ASF CANNOT:

• Issue binding compensation orders to pay you directly (that requires arbitration or court)
• Resolve SNS or ADSE disputes — those go through the healthcare system and ERS
• Act as your legal representative

Practical effect: ASF complaints work best as regulatory pressure tools. Insurers — especially large ones like Fidelidade, Médis, and Allianz — often resolve individual complaints when they learn an ASF inquiry is open, to avoid the risk of a formal finding against them.

Mandatory First Step: The Provedor do Cliente

Before ASF will accept your complaint, you must demonstrate you have completed the insurer's internal complaint process. In Portugal, this specifically means using the Provedor do Cliente mechanism.

What Is the Provedor do Cliente?

Every insurance company supervised by ASF in Portugal is required to:

1. Appoint an independent Provedor do Cliente (customer ombudsman), or
2. Adhere to a sector-wide Provedor scheme

The Provedor do Cliente reviews complaints independently from the insurer's claims and customer service departments. The Provedor's decision represents the insurer's final internal position.

How to Use the Provedor do Cliente

1. First, file a standard reclamação (complaint) with your insurer's customer service or claims department
2. If the response is unsatisfactory (or no response arrives within 20 working days), request escalation to the Provedor do Cliente specifically
3. The Provedor must respond within the regulatory timeframe — typically 20 to 30 working days from the escalation
4. Keep all written correspondence, including the Provedor's final decision letter

Once you have the Provedor's decision (or evidence of non-response), you are ready to file with ASF.

Step-by-Step: Filing an ASF Complaint

Step 1: Prepare Your Documents

Gather the following before submitting:

• Your insurance policy (apólice de seguro) and Condições Gerais de Seguro (CGS)
• The claim denial letter from your insurer
• Your reclamação to the insurer and the insurer's response
• The Provedor do Cliente's decision (or evidence that the Provedor did not respond)
• All supporting evidence: medical reports, invoices, receipts, diagnosis documents, photographs, expert opinions
• A concise written summary of the dispute: the service denied, the amount, the insurer's stated reason, and why you believe the denial was incorrect

Step 2: Submit Online (Recommended)

1. Visit asf.com.pt
2. Navigate to "Consumidores" → "Reclamações"
3. Complete the online reclamação form with your personal details, the insurer's details, and a description of the dispute
4. Upload all documents in PDF format
5. Submit — you will receive an automatic email confirmation with a reference number

Keep the reference number for all future correspondence with ASF about your case.

Step 3: Alternative Submission Methods

By post (carta registada com aviso de receção): Autoridade de Supervisão de Seguros e Fundos de Pensões Avenida da República, 76 1600-205 Lisboa

Include all documents as described above, plus a cover letter with your contact details.

In person: ASF's Lisbon headquarters accepts in-person complaint submissions during business hours. Bring originals and copies — ASF certifies copies and returns originals.

There is no filing fee for an ASF complaint.

Step 4: ASF Review Process

After receiving your complaint, ASF will:

1. Assess admissibility (ensure it falls within ASF's scope and the Provedor step was completed)
2. Formally notify your insurer of the complaint and request documentation and a substantive response
3. Review both sides' submissions
4. Issue a written response to you summarising the outcome

Timeline: ASF targets responses within 20 to 60 working days, depending on complexity. You may be contacted for additional information during the review.

Step 5: Outcome

ASF's response will either:

• Find that your insurer's conduct violated ASF regulations — triggering supervisory action against the insurer
• Find no regulatory violation — without prejudicing your right to pursue the dispute through mediation or courts

Either way, you receive ASF's written analysis, which is valuable evidence for subsequent proceedings.

After ASF: Arbitration and Courts

If ASF's involvement does not prompt your insurer to pay:

Consumer Arbitration Centres

Portugal has regional consumer arbitration centres (Centros de Arbitragem de Conflitos de Consumo) that provide free or low-cost binding arbitration for consumer insurance disputes:

• CACCL (Lisboa): centrodearbitragem.pt
• Centro Nacional de Informação e Arbitragem de Conflitos de Consumo (CNIACC): cniacc.pt

Julgados de Paz (Peace Courts)

For claims up to €15,000: Julgados de Paz across Portugal offer informal, fast proceedings at no cost. Suitable for most straightforward health insurance reimbursement disputes.

Civil Courts

For larger claims or complex disputes, the Tribunal de Comarca (district court) handles insurance contract litigation under Portuguese civil procedure. Legal representation (advogado) is advisable.

Tips for a Successful ASF Complaint

• Document the Provedor do Cliente step: ASF will check that you completed this. A complaint missing this step will be returned.
• Be factual and reference your policy: Quote the specific CGS clause Médis or Fidelidade cited, and explain precisely why it does not apply to your situation
• State the amount clearly: Specify the exact euros denied (and your out-of-pocket costs, if any)
• ASF communication is in Portuguese: Submissions in other languages may delay processing. If Portuguese is not your first language, seek assistance from a Portuguese-speaking advisor
