Signature and Document Recognition in Portugal

In many situations, you will need to officially prove that a document is yours, or that a signature corresponds to a specific person. This is called signature recognition or document certification. It is not the same as apostilling (an extra layer) — this guide explains the differences and where to do each one.

Types of Recognition (in order of legal strength)

1. Simple Recognition (In-Person)

The person signs the document in the presence of the notary or lawyer, who confirms the identity through physical presence. It is the cheapest and simplest.

Who does it:

• Notaries
• Lawyers with notarial powers
• Solicitors
• Civil Registry Offices
• Citizen Spaces / Citizen Shops (for some specific documents)

Cost: 8-25 EUR depending on the location.

Time: 5-15 min.

When you need it:

• Powers of attorney
• Declarations
• Private contracts (especially between foreigners)

2. Recognition by Similarity

The notary compares the signature on the document with the registered signature (e.g., citizen card, passport, notarial record). You do not need to be present.

Who does it: notaries and lawyers with notarial powers.

Cost: 10-30 EUR.

Time: Immediate if the notary has your registered signature.

When you need it: private documents that you signed but did not present in person.

3. Recognition with Special Mentions

A variant of simple or similarity recognition, but with an additional mention from the notary about the position, function, or powers of the person (e.g., "I recognize the signature of João Silva, in the capacity of manager of company X").

When you need it: signatures on behalf of a company or organization.

Cost: 15-50 EUR.

4. Certification of Copy (from original)

The notary, lawyer, or Citizen Space certifies that the copy is faithful to the original that they have seen. You go to the counter with the original + as many copies as you want certified.

Cost: 5-15 EUR per document (some multiple copies for a single price).

When you need it: to submit a certified copy when the agency does not accept a simple one (e.g., AIMA, schools, competitions).

5. Certified Translation

For foreign documents in a language other than Portuguese, you need sworn translation + recognition of the translator's signature.

Who does it: accredited sworn translators (list available at Portuguese consulates abroad, or registered translators in PT).

Cost: 25-60 EUR per page, depending on the language.

Hague Apostille (international layer)

The Apostille is an additional certification that validates a Portuguese document for use in another country (and vice versa) — as long as the country is a signatory to the Hague Convention. In Portugal:

Who apostilles: Attorney General's Office.

Where:

• Lisbon: Rua da Misericórdia, 18, 1249-097 Lisbon
• Porto: Rua de S. Bento, 7, 4050-538 Porto
• Coimbra: Rua da Sofia, 13, 3000-389 Coimbra
• Appointment required at pgr.pt

Cost: 12 EUR per apostille.

Time: 1-3 business days in person, or 5-10 days by mail.

When you need it:

• To present a Portuguese diploma in another country
• To present a birth, marriage, or death certificate in another country
• To present a contract or power of attorney in another country

Important: the apostille only works between countries that are signatories to the Hague Convention (~120 countries, including Brazil, Angola, Mozambique, Cape Verde, USA, EU, etc.). For non-signatory countries, full consular legalization is required (slower and more expensive).

Foreign Documents to Use in Portugal

Do you have a birth certificate from Brazil, or a diploma from Angola? To use it officially in Portugal, you need:

1. Apostille the original document in the country of origin (in Brazil it is free at authorized notaries; in Angola at the Directorate of Registries and Notary)
2. Translate into Portuguese (sworn) if it is not in Portuguese
3. In Portugal: there may be additional recognition depending on the use

For CPLP countries (Angola, Brazil, Cape Verde, Guinea-Bissau, Mozambique, São Tomé), there are treaties of exemption from legalization that accept documents with only certified translation for some types (education, civil).

Where to Do It (practical list)

For simple recognitions and certified copies

• Citizen Spaces / Citizen Shops — cheaper (8-15 EUR), quick service
• IRN (Institute of Registries and Notary) — for in-person signature recognitions
• Private Notaries — more expensive (15-30 EUR) but with extended hours
• Lawyers — equivalent to notary, especially useful if you already have a lawyer for another reason

For apostille

• Attorney General's Office in the 3 cities above

For specific immigrant services

Look for specialized lawyers and offices in E-migrantes that support the diaspora — many offer packages (power of attorney + apostille + translation) for a fixed price.

Common Mistakes

1. Requesting recognition by similarity without having a registered signature — the notary needs a prior reference (CC, passport, previous record). Without this, it must be in person.
2. Apostilling non-public documents — apostille only serves for documents issued by a public authority. A private power of attorney needs to be first recognized by the notary, then apostilled.
3. Apostilling a document without reading what the recipient needs — many countries require a "double-apostille" or consular version. Always confirm with the recipient first.
4. Non-swear translation — a simple translation from Google Translate (even stamped) is not valid. It must be an accredited translator.
5. Paying private "dispatchers" — in PT these services are all public. If someone charges you 200 EUR to obtain an apostille, it is a scam.

Typical Costs of a "Complete Package"

Scenario: you want to present your Angolan birth certificate to a Portuguese public agency.

Step	Cost
Apostille the certificate in Luanda	~10-30 EUR
Sworn translation in PT	35-50 EUR
Recognition of the translator's signature	10-15 EUR
Total	55-95 EUR
