Portuguese Perfilhação Certificate: Paternity Recognition Online

---

What Is a Perfilhação Certificate in Portugal?

In Portuguese civil registration, perfilhação means the voluntary recognition of paternity. The father making the recognition is the perfilhante, while the recognized child is the perfilhado or perfilhada.

The certificate is officially called a certidão de perfilhação. It proves the facts recorded in that civil registry entry, which identifies the recognized child and the recognizing father. In English, it may also be described as a Portuguese paternity recognition certificate or acknowledgment of paternity certificate.

This is not a DNA test, a medical certificate, or an informal declaration. It is official proof of a legal act registered with the Portuguese civil registry.

Is Requesting the Certificate the Same as Recognizing Paternity?

No. This distinction is essential.

Ordering the certificate does not create paternity or allow someone to recognize a child for the first time. If no perfilhação exists, the recognition must first be registered through the Portuguese civil registry.

What Does a Portuguese Perfilhação Certificate Prove?

According to the Portuguese civil registry service, the register identifies:

• The recognized child (perfilhado or perfilhada)
• The recognizing father (perfilhante)
• The registered voluntary recognition of paternity

The official public page does not list every field that will appear in every issued certificate. If an authority asked for the document, confirm whether it accepts the electronic certificate or requires paper, translation, legalization, or an apostille.

Who Can Request a Perfilhação Certificate?

As a general rule, any person can request a Portuguese perfilhação certificate, including one concerning someone else. The important exception is a record protected by legal secrecy.

When is a perfilhação record secret?

The record stays secret when the recognized child was already an adult at the time of the recognition (or, if the child had died, had adult descendants) and their consent has not yet been recorded. Since April 2025, minors can no longer marry, so emancipation by marriage no longer applies to new cases.

A standard certificate request cannot override those protections. AnchorLess cannot obtain a secret record through this service. The law allows a certificate of a secret record only for a marriage file or a child-maintenance case, requested through the registry for that purpose. If you are unsure whether the record is eligible, contact a Portuguese civil registry office or a qualified Portuguese legal professional before ordering.

What Information Do You Need to Make the Request?

To help locate the correct record, prepare:

• The child's full name and date of birth
• The child's country and place of birth
• The recognizing father's full name and date of birth
• The recognizing father's country and place of birth
• For anyone born in Portugal, the district, municipality (concelho) and parish (freguesia) of birth: the official form requires them
• Your email address and a phone number

Use the names, accents, dates, and birthplaces recorded in Portugal whenever possible. If you know the record number and year, add them: they help the registry find it.

How to Obtain a Portuguese Perfilhação Certificate Online

You can request an eligible, existing certificate through AnchorLess or directly through Portugal's online civil registry service.

Through AnchorLess

1. Start the online perfilhação certificate application.
2. Enter the recognized child's name, date of birth, and place of birth.
3. Provide the recognizing father's name, date of birth, and place of birth.
4. Add your contact information and review the request.
5. Pay securely online.
6. AnchorLess checks and submits the application.
7. Receive updates and the completed certificate by email.

Directly through the Portuguese registry

1. Open the online civil certificate request service.
2. Complete the applicant and registry information.
3. Select the perfilhação certificate.
4. Pay by bank payment reference or card within 48 hours, or the request is cancelled. From abroad, pay by card at the end of the request: a Multibanco reference needs a Portuguese bank.
5. Wait for the registry to validate and issue the certificate.
6. Use the access code supplied after issue to consult it online.

You may authenticate on Civil Online or continue without authentication. Neither the direct service nor an intermediary can bypass the rules protecting a secret record.

Problem with a request, or a mistake in your email address (the access code is sent there)? Contact the Civil Online helpdesk: +351 211 950 500 or civilonline@irn.mj.pt, on weekdays from 9:00 to 17:00.

Costs, Format and Processing Time

The official Portuguese registry fees are:

AnchorLess charges a separate assistance price, displayed before payment. AnchorLess currently estimates that most assisted requests are completed within 3–7 business days, but registry searches or incomplete details can extend delivery.

The authorities do not publish a guaranteed fixed processing time. The AnchorLess estimate is therefore a service estimate rather than an official deadline.

Is the Electronic Certificate Legally Valid?

Yes. The electronic certificate contains the same information and has the same legal value in Portugal as the paper version. Its access code remains valid for six months from the issue date, and consultation with a valid code is free.

Sharing that code with a public or private organization during its validity period is equivalent in Portugal to providing the paper certificate. The code cannot be renewed; after it expires, a new request is required.

A screenshot or ordinary printout of the consultation page is not itself a substitute for the electronic certificate and valid access code.

Can You Request the Certificate from Abroad?

Yes. You do not need to live in Portugal or visit a Conservatória do Registo Civil to order an eligible, non-secret certificate online.

Check Portuguese spellings, accents, dates, and birthplaces carefully because mismatches can complicate the registry search. For use abroad, ask the receiving authority whether it accepts the digital code or requires paper, translation, legalization, or an apostille. The online certificate is in Portuguese only, not in the international multilingual model. For a country outside the EU, you can request an electronic apostille online from the Public Prosecutor's office (€10.20); within the EU, no apostille is needed. Portuguese consulates can also issue it (consular fee €20).

Perfilhação Certificate vs Birth Certificate

These civil registry documents are related, but they do not prove exactly the same record.

A birth certificate may show legal parentage; a perfilhação certificate specifically proves the registered recognition. One does not automatically replace the other.

If you also need the person's birth record, read our guide on how to obtain a Portuguese birth certificate online.

For proof of a voluntary recognition of maternity, read our companion guide to the Portuguese maternity declaration certificate.

For nationality through a Portuguese father, only a recognition made while the child was a minor counts. A recognition made in adulthood counts only if a court established it, and you then have three years to apply. This certificate is not automatically required or sufficient. Our guide to Portuguese citizenship through a parent explains the broader process.

Common Problems When Requesting the Certificate

• No registered recognition: A certificate request cannot create a perfilhação; the act must already exist.
• Secret record: No standard request or intermediary can bypass the consent rules.
• Mismatched details: Check complete names, accents, dates, and birthplaces for the child and father.
• Expired access code: A new certificate request is required after six months.
• Wrong document or format: Confirm whether the receiving authority needs this certificate, a birth certificate, paper, translation, or an apostille.
• The record is very old: records held in a District Archive cannot be issued online. If the registry refuses a request, the fee is refunded.

Frequently Asked Questions

Key Takeaways

A Portuguese perfilhação certificate proves a voluntary recognition of paternity already recorded in Portugal. It can usually be requested online by anyone, including from abroad, but records protected by legal secrecy cannot be supplied through a standard request.

Make sure you need the certificate rather than the registration procedure, provide exact details, and confirm the required format. The direct government fee is €10 and the electronic access code remains valid for six months.
