Granting Public Power of Attorney for Vehicle Purchase, Sale, and Transfer
A public power of attorney for vehicles is the notarial act by which the owner (grantor) confers powers upon another person (attorney-in-fact or grantee) to manage, sell, purchase, or transfer ownership of a motor vehicle before traffic departments, insurance companies, and financial institutions. Drawn up exclusively at a notary public office (tabelionato de notas), this tool ensures authenticity and legal certainty for the transaction (Lei nº 8.935/1994 — Notarial and Registral Services Law, art. 6º Lei nº 8.935/1994, art. 6º and art. 1º Lei nº 8.935/1994, art. 1º).

How does granting a public power of attorney for vehicles work at a notary public office?
Granting a public power of attorney for vehicles at a notary public office (tabelionato de notas) occurs when the titleholder of the asset declares their intent before a notary or authorized clerk. The act ensures verification of the parties' identities, civil capacity, and free exercise of will. Formalization by public instrument confers public faith and a presumption of truthfulness upon the document (Lei nº 10.406/2002 — Civil Code, art. 215 Lei nº 10.406/2002 — Código Civil, art. 215).
The notarial act can be performed at any notary public office in the country, regardless of the domicile of the parties or where the vehicle is registered. Following the consolidation of notarial standards by the National Council of Justice (CNJ) through Provimento CNJ nº 149/2023, citizens may also opt for digital execution via the e-Notariado platform using videoconferencing and a notarial digital signature.
When executing the public power of attorney for vehicles, the notary transcribes in detail the identification data of the grantor, the attorney-in-fact, and the vehicle's specifications, including license plate, chassis number (VIN), make, model, and RENAVAM (National Motor Vehicle Registry) code. This level of detail prevents fraud in commercial transactions and guarantees immediate acceptance by state traffic repositories and insurance providers.

What documents are required to issue a public power of attorney for vehicles?
To request a public power of attorney for vehicles, you must submit complete documentation for all involved parties for proper qualification and precise identification of the vehicle subject to the power of attorney.
You must provide the following original documents or certified copies:
- Official identification document of the grantor: National Identity Card (RG), Driver's License (CNH), professional identity card with photo, or valid passport.
- Individual Taxpayer Registry (CPF) of the grantor, along with statement of occupation, marital status, and residential address.
- Full qualification of the attorney-in-fact: simple copy of photo ID, CPF, marital status, occupation, and address.
- Vehicle document: Electronic Vehicle Registration and Licensing Certificate (CRLV-e) or the former physical Vehicle Registration Certificate (CRV).
- Marriage or birth certificate: required to confirm marital status and verify whether the marital property regime requires spousal consent for disposal.
When the grantor is a legal entity, it is essential to present the consolidated articles of incorporation or bylaws accompanied by the corporate resolution electing the current board of directors, in addition to the CNPJ (Corporate Taxpayer Registry) card. The notary evaluates the company's management clause to confirm whether the partner or director holds independent authority to grant the public power of attorney for vehicles.

What is the difference between powers with economic value and simple powers in a public power of attorney for vehicles?
The distinction between simple powers and powers with economic value in a public power of attorney for vehicles impacts the legal scope of representation and the applicable statutory fee table in each state.
A power of attorney with simple powers focuses on routine management and administrative procedures. It authorizes the attorney-in-fact to retrieve the vehicle from impound lots, pay traffic fines, request duplicate documents, contract vehicle protection plans, and request inspections before the State Department of Traffic (DETRAN). This act does not transfer ownership of the asset nor permit its sale.
Conversely, a power of attorney with economic powers grants authority to dispose of, sell, encumber as collateral, stipulate prices, sign transfer documents, and issue receipts for funds received. Due to the financial impact involved, these acts require stricter notarial scrutiny.
To deepen your understanding of the differences between types of notarial mandates, consult our detailed analysis on the distinction between general and special powers in public notary powers of attorney.

Is it possible to issue a public power of attorney for vehicles allowing transfer to the attorney-in-fact themselves?
Yes, Brazilian law permits the issuance of a public power of attorney for vehicles in one's own interest (also known as a power of attorney in rem suam). This special modality allows the grantee to transfer ownership of the vehicle to their own name or to third parties designated by them.
Pursuant to the rules of the Civil Code (Lei nº 10.406/2002), a power of attorney in one's own interest is equivalent to a rights-conveying contract ([VERIFY: Civil Code, art. 685]). For this reason, it must contain essential requirements, such as precise identification of the vehicle, fixed sales price, an explicit statement of payment release given by the grantor, and exemption from accounting duties.
A power of attorney in rem suam does not lapse or terminate upon the death or legal incapacity of either party. However, the grantor remains subject to tax and civil liabilities until the formal registration of the ownership change is recorded with the competent traffic authority.
To understand the operational requirements for in-person and digital executions, consult our manual on in-person and digital public power of attorney on e-Notariado.

How long does a public power of attorney for vehicles remain valid with DETRAN and insurance companies?
Under Brazilian civil law, a public power of attorney for vehicles granted for an indefinite term remains legally effective indefinitely until formal revocation occurs, the attorney-in-fact resigns, or one of the parties passes away.
Despite this general rule, administrative bodies such as the State Department of Traffic (DETRAN), financial institutions, and insurance companies establish internal regulations for document acceptance. Due to the risk of uncommunicated revocations, these entities commonly require an updated certificate of the power of attorney (certidão de procuração), issued by the notary public office within the preceding 30 or 90 days.
Issuing an updated certificate confirms that the act remains valid in the notary's book and has not been subject to any entry of revocation or annulment. When a vehicle suffers a total loss in an insured event, insurance companies require this power of attorney to deregister the vehicle from traffic records and process the corresponding claim payout.

What happens if a vehicle is sold under a power of attorney and the new owner does not complete the transfer at DETRAN?
Granting a public power of attorney for vehicles with powers to sell does not automatically transfer legal ownership of the asset before the state traffic department. If the buyer or attorney-in-fact delays or fails to complete the transfer at DETRAN, the former owner remains recorded as the official titleholder in administrative registers.
This failure creates severe legal and financial consequences for the grantor:
- Imposition of fines and points on the driver's license: traffic infractions committed by the new driver will be attached to the formal owner's record.
- Tax liability for vehicle taxes (IPVA): State tax authorities will continue to assess the Motor Vehicle Property Tax (IPVA) and licensing fees against the individual listed in the official registry.
- Civil liability for accidents: in severe traffic accidents, victims may seek damages against the owner listed in traffic records.
To prevent these liabilities, the seller must submit a notice of sale (comunicação de venda) to DETRAN immediately after signing the Electronic Vehicle Transfer Authorization (ATPV-e) or request the notary public to communicate the act, keeping a certified copy of the signed and dated document ([VERIFY: Brazilian Traffic Code, art. 134]).

In practice
Case 1: Sale of a vehicle with owner living abroad
A citizen moved abroad and needed to sell a vehicle located in Brazil. He scheduled an online appointment through the e-Notariado platform and granted a public power of attorney for vehicles with specific sale powers to a relative. The attorney-in-fact presented the public power of attorney and the ATPV-e at the notary public office, signed the transfer on behalf of the owner, and completed the ownership transfer at DETRAN without complications.
Case 2: Recovery of an impounded vehicle from a DETRAN impound lot
A driver had their vehicle impounded at a traffic department lot due to unpaid licensing fees while away on a business trip. Unable to return in time, the owner visited a local notary public office and executed a simple power of attorney with administrative powers in favor of his brother. Armed with the power of attorney, the representative paid the required fees, completed mandatory inspections, and retrieved the vehicle promptly.

Frequent errors
- Using a private contract without notarized signatures: informal private contracts or private powers of attorney lacking statutory formalities are routinely rejected by DETRAN for ownership transfer.
- Believing that a power of attorney replaces the transfer of title: handing over a power of attorney does not release the seller from the legal obligation to complete the notice of sale.
- Omitting vehicle identification details in the power of attorney: instruments containing incomplete license plate or VIN data are rejected by insurance companies and public agencies.
- Granting disposal powers without considering the marital property regime: selling assets during marriage under community property regimes may require explicit spousal consent.

Frequently asked questions
How does granting a public power of attorney for vehicles work at a notary public office?
You appear at a notary public office (tabelionato de notas) with your personal identification documents and vehicle details to transfer powers to a third party. The notary verifies the identities of the parties, drafts the public instrument, and guarantees public faith and legal security for the procedural act.
What documents are required to issue a public power of attorney for vehicles?
You must present an official photo ID, CPF, updated proof of residence, civil status certificate, and a copy of the vehicle registration document (CRLV-e or CRV) containing full identification details of the vehicle.
What is the difference between powers with economic value and simple powers in a public power of attorney for vehicles?
A power of attorney with economic value involves direct powers for disposition, sale, receipt of funds, or debt payoff, altering the applicable notarial fee schedule. A simple power of attorney is intended solely for administrative matters, debt regularization, and vehicle retrieval at DETRAN.
Is it possible to issue a public power of attorney for vehicles allowing transfer to the attorney-in-fact themselves?
Yes, this modality is known as a power of attorney in one's own interest (in rem suam). It requires explicit specification of the price, payment release, and sales conditions, functioning as the conveyance act itself under civil law.
How long does a public power of attorney for vehicles remain valid with DETRAN and insurance companies?
A public power of attorney executed for an indefinite term retains legal validity until revoked or upon the death of either party. However, agencies such as DETRAN and insurance companies may require an updated certificate of the power of attorney issued within the preceding 30 or 90 days.
What happens if a vehicle is sold under a power of attorney and the new owner does not complete the transfer at DETRAN?
The registered owner remains legally liable for traffic fines, points on their driver's license, and state vehicle taxes (IPVA). The power of attorney grants authority to act on their behalf, but does not replace the official notice of sale or the actual transfer of title with the traffic authority.
