What is a public power of attorney and when is it mandatory?
A public power of attorney (procuração pública) is a formal legal instrument executed by a notary public (tabelião de notas) that confers powers of representation from one person to another Lei nº 8.935/1994, art. 6º. It differs from a private instrument because it carries public faith (fé pública), is permanently archived in a notarial ledger, and allows for the issuance of official certified copies (certidões) at any time Lei nº 10.406/2002 — Código Civil, art. 215.
You must use a public power of attorney when the law requires a public instrument for the principal transaction. For instance, executing a public deed of purchase and sale of real estate requires the representative to present a public power of attorney. Financial institutions, public administration agencies, and the National Social Security Institute (Instituto Nacional do Seguro Social — INSS) also typically require the public format to authorize financial transactions or administrative requests.
In addition to fulfilling legal requirements, a public power of attorney provides security to all parties. The notary verifies the legal capacity of the grantor, confirms the identity of the parties involved, and guarantees the free expression of will Lei nº 10.406/2002 — Código Civil, art. 104. To further analyze its application in banking institutions, consult the article on public power of attorney in a notary office.

What documents are required to execute a public power of attorney for an individual or a legal entity?
To initiate the procedure at a notary office (tabelionato de notas), the grantor must present valid and updated personal documentation. Accurate qualification and document verification prevent defects that could lead to the nullity of the legal transaction Lei nº 10.406/2002 — Código Civil, art. 166.
When the grantor is an individual, you must submit:
- Official photo identification document (RG, CNH driver's license, or professional council ID card);
- Individual Taxpayer Registry card (CPF — Cadastro de Pessoas Físicas);
- Updated proof of residence;
- Marriage or birth certificate to verify marital status.
If the grantor is a legal entity, the documentation covers the company's founding documents:
- Consolidated Articles of Association (Contrato Social) or Bylaws (Estatuto Social) accompanied by the latest amendment;
- Corporate Taxpayer Registry proof (CNPJ) obtained from the Receita Federal (Federal Revenue Service) website;
- Simplified Certificate (Certidão Simplificada) from the Commercial Registry (Junta Comercial) issued within the last 90 days;
- Personal identification documents of the legal representative authorized to grant the public power of attorney.
The identification details of the attorney-in-fact (grantee) must also be provided (full name, marital status, occupation, RG, CPF, and residential address). The physical presence of the attorney-in-fact at the notary office is not required for execution; only the grantor's appearance is required.

How to correctly draft powers to prevent rejection by banks and public agencies?
Drafting the text of a public power of attorney requires technical clarity and specification. Powers are divided into general powers (for ordinary administration) and special powers (for acts disposing of rights, encumbrance, alienation, and settlement).
Rejection of powers of attorney by banks and public offices occurs most often due to a lack of express powers. Acts such as selling property, mortgaging, confessing debts, settling disputes, waiving rights, or making donations require detailed specification of the act and the subject matter.
> Practical drafting example: To sell a specific piece of real estate, it is not sufficient to include the phrase "powers to sell real estate." The text must explicitly state the property's address, registration number (matrícula), and competent Real Estate Registry (Registro de Imóveis).
To better understand the application of contractual and representative provisions, see the guide on general and special powers in public powers of attorney.

Is it possible to execute a public power of attorney while abroad or through digital means?
You can issue a public power of attorney even while abroad or without physically attending the notary office. Technology and regulations established by the Conselho Nacional de Justiça (National Council of Justice — CNJ) facilitate this service.
If you are abroad, there are two main options:
- Brazilian Consular Post: Appear at a Brazilian Consulate or Embassy to execute the public power of attorney before a Brazilian consular authority.
- Local Notary and Apostille: Execute the power of attorney before a local notary public in the foreign country, obtain a Hague Apostille on the document, and, upon sending it to Brazil, arrange for a sworn translation (tradução juramentada) and registration at the Registry of Titles and Documents (Registro de Títulos e Documentos).
If you hold an ICP-Brasil digital certificate or a notarial digital certificate (issued free of charge via e-Notariado), you can execute a public power of attorney 100% digitally Lei nº 14.382/2022, art. 3º. The notary conducts a videoconference to verify identity and receive the expression of intent, signing the act electronically Provimento CNJ nº 149/2023, Livro II. Check details in the article on in-person and digital public power of attorney.

What is the validity period of a public power of attorney and how to cancel it?
Under Brazilian law, a public power of attorney does not expire simply by the lapse of time, unless the grantor explicitly sets an expiration date within the document text. However, entities such as Caixa Econômica Federal, the INSS, and the Traffic Department (Detran) may demand updated certified copies issued within the last 30, 60, or 90 days.
Revocation is the act by which the grantor withdraws the granted powers. It is performed through a public deed of revocation (escritura pública de revogação de procuração) executed at a notary office (tabelionato de notas).
For revocation to take effect against third parties and against the attorney-in-fact, formally notifying the attorney-in-fact is essential. Cancellation can also be annotated in the margin of the notary ledger where the original act was recorded. Furthermore, a power of attorney terminates upon the death of either party, legal incapacity (interdição), or completion of the specified transaction.

In practice
Case 1: Property sale via power of attorney granted to a son
A property owner residing in Recife wished to sell an apartment to purchase another property but would be traveling during the negotiation period. He went to the notary office (tabelionato de notas) and executed a public power of attorney granting specific powers to his son. In the text, they specified the property's registration number (matrícula) and expressly authorized the signature of the public deed of purchase and sale. The transaction was completed without operational delays.
Case 2: Remote issuance for a citizen living abroad
A Brazilian citizen living in Spain needed to manage a bank account linked to an estate probate proceeding (inventário) in Brazil. She used the e-Notariado platform to complete the digital procedure. The notary office conducted the videoconference, verified the applicant's identity and legal capacity, and executed the electronic public power of attorney. The digitally signed document was accepted immediately by the receiving financial institution.

Frequent errors
- Error: Using generic terms such as "broad and unrestricted powers" to sell real estate.
How to avoid: Legislation requires express and special powers to alienate or encumber real estate. Detail the exact subject matter of the transaction.
- Error: Assuming that the attorney-in-fact must sign the notary book at the time of executing the public power of attorney.
How to avoid: A power of attorney is a unilateral act. Only the grantor signs the instrument at the notary office.
- Error: Failing to notify the former attorney-in-fact after executing the deed of revocation.
How to avoid: Revocation takes practical effect against the attorney-in-fact only from the moment they receive formal notification. Request notification via the Registry of Titles and Documents (Cartório de Títulos e Documentos).
- Error: Attempting to use a power of attorney from a deceased person to execute legal transactions.
How to avoid: Representation terminates at the exact moment of the grantor's death. Assets must be processed through probate (inventário).
