Brazil Recording Laws: One-Party Consent Rules and Penalties (2026)

How Recording Consent Works in Brazil

Brazil is a one-party consent country. If you are part of a conversation, you may record it. No permission from the other person is required. No announcement is necessary. This applies to phone calls, in-person meetings, WhatsApp audio, Zoom calls, and every other form of communication where you are a genuine participant.

The rule holds for private citizens and businesses alike. A salesperson can record their own client calls. An employee can record a meeting with a supervisor. A tenant can record a landlord's verbal demands. The legal test is straightforward: were you actually part of the exchange? If yes, the recording is lawful.

What Brazil prohibits is something different. Third-party interception, where someone who is not part of the conversation secretly captures it, is a crime. If Maria and João are talking and Pedro records them without either knowing, Pedro has committed a criminal offense. If Maria records that same conversation herself, she has not.

This distinction between participant recording (gravação) and third-party interception (interceptação) is the foundation of Brazil's entire recording law framework.

The Constitutional Basis: Article 5, Inciso XII

Brazil's 1988 Federal Constitution addresses communication privacy in Article 5, which enumerates fundamental rights. Inciso XII declares the secrecy of correspondence, telegraphic communications, data, and telephone communications to be inviolable.

The constitution carves out one narrow exception. Telephone interception may be ordered by a court, under the conditions and procedures established by law, solely for criminal investigation or criminal proceedings. Congress enacted Lei 9.296/1996 to define those conditions and procedures.

Constitutional scholars and the Supreme Federal Court have consistently held that Article 5, Inciso XII protects against third-party interception, not against a participant's decision to record their own conversation. The rationale is that you already possess the information exchanged in a conversation you are part of. Preserving that information through a recording does not violate anyone's constitutional right to secrecy of communications. It simply creates a record of something you already heard.

Lei 9.296/1996: Brazil's Wiretapping Statute

Lei 9.296, signed into law on July 24, 1996, is the primary statute governing the interception of communications in Brazil. It implements the constitutional exception for court-ordered surveillance and defines criminal penalties for unauthorized interception.

When Courts May Authorize Interception

A judge with jurisdiction over the underlying criminal case may authorize the interception of telephone or telematic communications when all of the following conditions are satisfied:

• Reasonable grounds indicate the target is involved in a criminal offense.
• The alleged crime carries a penalty of imprisonment (not merely a fine or detention).
• The evidence sought cannot be obtained through any other available means.

Each authorization lasts up to 15 days. The judge may renew it for additional 15-day periods as needed. The judge monitors the interception throughout and may terminate it at any time.

Article 10: The Core Criminal Prohibition

Article 10 of Lei 9.296/1996 makes it a crime to intercept telephone, computer, or telematic communications without judicial authorization or for purposes outside the scope of an existing authorization. It also criminalizes breaking the secrecy (sigilo) of a judicially authorized interception.

The penalty is 2 to 4 years of imprisonment (reclusão) plus a fine. This applies to private citizens, company executives, and government officials who order or carry out unlawful surveillance.

Article 10-A: The 2020 Pacote Anticrime Carve-Out

Lei 13.964/2019, known as the Pacote Anticrime (Anti-Crime Package), took effect in January 2020. Among its many changes to Brazilian criminal law, it inserted a new Article 10-A into Lei 9.296/1996.

Article 10-A criminalizes the unauthorized capture of electromagnetic, optical, or acoustic signals for the purpose of criminal investigation or instruction, when such capture requires judicial authorization but is conducted without it. The penalty matches Article 10: 2 to 4 years of imprisonment plus a fine.

The provision that matters most for everyday recording is Paragraph 1 of Article 10-A. It states plainly: "Não há crime se a captação é realizada por um dos interlocutores." There is no crime if the capture is made by one of the interlocutors.

This paragraph took what had been judicial interpretation and wrote it directly into statute. Before 2020, the legality of participant recording rested on constitutional analysis and court precedent. After the Pacote Anticrime, it is black-letter law.

Doubled Penalties for Public Officials

Paragraph 2 of Article 10-A provides that the penalty is doubled for a public official who breaches the confidentiality requirements governing environmental recording operations. The same applies to a public official who discloses the content of recordings while a judicial secrecy order remains in effect.

STF Precedent: RE 583.937 (Tema 237)

The Supreme Federal Court's most significant ruling on participant recording came in Recurso Extraordinário 583.937, decided on November 19, 2009. The court recognized general repercussion (repercussão geral), meaning the holding binds all lower courts across Brazil.

The binding thesis (tese): "É lícita a prova consistente em gravação ambiental realizada por um dos interlocutores sem conhecimento do outro." Translation: "Evidence consisting of an environmental recording made by one of the interlocutors without the knowledge of the other is lawful."

The court's reasoning is grounded in a simple observation. If a person can testify about what was said in a conversation they participated in, there is no logical basis for declaring the recording of that same conversation unlawful. The recording preserves information the participant already possesses. No secret is breached because the recorder was present for the communication.

RE 583.937 applies across nearly every area of Brazilian law. Criminal courts, labor courts (Justiça do Trabalho), civil courts, and administrative tribunals all follow this precedent when evaluating the admissibility of participant recordings.

The only significant limitation recognized by the court is the existence of a specific reason for secrecy tied to a professional or ministerial relationship. Conversations protected by attorney-client privilege, religious confession, or medical confidentiality may receive different treatment.

STJ Reaffirmation: 2024 Fifth Panel Decision

In August 2024, the Fifth Panel (Quinta Turma) of the Superior Court of Justice issued a decision that refined and strengthened the participant recording doctrine. The case involved a clandestine environmental recording made by a victim to document ongoing criminal conduct.

The STJ held that a participant's secret recording is valid evidence when the right being protected carries greater weight than the privacy interest of the person recorded. The panel applied a balancing test: the victim's rights to dignity, physical integrity, and access to justice outweighed the offender's expectation of privacy.

The court noted that this conclusion follows naturally from the exclusion of unlawfulness (excludente de ilicitude) recognized in Brazilian criminal law. A person who records to defend against unjust aggression is exercising a legal right, not committing a crime.

The STJ also emphasized practical reality. In many situations, particularly domestic violence, harassment, and fraud, a secret recording by the victim is the only available evidence. Declaring such recordings inadmissible would effectively deny justice to victims who have no other way to prove what happened.

The Electoral Exception: RE 1.040.515 (Tema 979)

One significant area of Brazilian law departs from the general one-party consent rule. In electoral proceedings, the STF has imposed stricter standards on covert recordings.

In RE 1.040.515 (Tema 979), decided in 2024 with binding effect, the STF established a two-part thesis:

First: In electoral proceedings, evidence obtained through clandestine environmental recording without judicial authorization is inadmissible, even when made by a participant, if it was captured in a private environment or an access-controlled public space and violates the privacy and intimacy of those involved.

Second: The exception to this rule of inadmissibility applies to recordings made in genuinely open public spaces with no access control, because in such spaces there is no reasonable expectation of privacy to violate.

The concern driving the electoral exception is the integrity of democratic processes. The STF reasoned that permitting covert recordings in private political meetings would create opportunities for manipulation and would undermine the conditions necessary for free political dialogue.

A practical example: recording a conversation inside a political party office, a candidate's car, or a private dinner meeting would be inadmissible in electoral court, even if the person recording was present. Recording a candidate's public speech at an open-air rally would not trigger the same restriction.

This exception applies only to electoral proceedings. It does not change the rules for criminal, civil, or labor cases.

Phone Calls and Digital Communications

Brazil's one-party consent principle applies to every form of communication in which the recorder is a genuine participant.

Telephone Calls

A person participating in a phone call may record it without the other party's knowledge. This covers mobile calls, landline calls, and voice-over-IP (VoIP) calls. No automated beep, tone, or verbal disclosure is legally required.

Messaging and Video Platforms

Recording a WhatsApp voice call, Telegram call, Zoom meeting, Google Meet session, or Microsoft Teams call is lawful for any participant. The underlying principle does not change with the medium. If you are in the conversation, you may record it.

Text-Based Communications

Saving, screenshotting, forwarding, or exporting a text conversation to which you are a party is lawful. Brazilian courts apply the same analytical framework across audio and text formats. A WhatsApp chat log printed and submitted as evidence receives the same treatment as a voice recording, provided authenticity is demonstrated.

In-Person and Environmental Recording

Face-to-face recording follows the same one-party rule. If you are physically present and participating in the conversation, you may record it.

The distinction between lawful participant recording and unlawful third-party interception is critical here. Placing a hidden microphone in a room to capture conversations you are not part of is not participant recording. It is environmental interception, and it falls squarely within the criminal prohibitions of Article 10-A of Lei 9.296/1996.

Body cameras, lapel microphones, phone voice recorders, and other devices are all lawful tools for a participant to use. The law focuses on the relationship between the recorder and the conversation, not on the technology used.

Recording in Public Spaces

Brazil does not prohibit filming, photographing, or recording audio in genuinely public spaces. Streets, plazas, parks, beaches, and other open areas are generally treated as spaces with a reduced expectation of privacy.

Recording police officers performing their duties in public is broadly understood to be lawful. This aligns with the constitutional principles of publicidade (transparency) and cidadania (citizenship). Citizen video has played a documented role in accountability proceedings involving police conduct.

The analysis shifts in access-controlled spaces that are nominally open to the public. A private event in a rented hall, a meeting inside a fenced venue, or a conversation in a restricted-access area of a building may carry a higher expectation of privacy. In such settings, the standard one-party consent analysis applies: if you are a participant in the conversation, you may record. If you are merely an observer recording someone else's private exchange, you face potential legal liability.

Workplace Recording

Employees Recording Employers

An employee who records a workplace conversation they are part of is protected under the one-party consent rule. The STF and STJ precedents apply in labor court (Justiça do Trabalho) just as they do in criminal and civil proceedings.

Brazilian labor courts have accepted participant recordings as evidence in cases involving moral harassment (assédio moral), sexual harassment, wrongful termination, unpaid wages, unsafe working conditions, and discrimination. The employee does not need to announce the recording or disclose it to the employer at the time it is made.

The TST (Superior Labor Court) validated in 2024 a recording made by a worker without consent as evidence against an employer, reinforcing that participant recordings are a recognized tool for employees seeking to protect their rights.

Employer Monitoring of Employees

Employers in Brazil may implement monitoring programs, but the LGPD and constitutional privacy protections impose clear boundaries.

Video surveillance through CCTV is permitted in work areas, provided the employer notifies employees that cameras are in use, explains the purpose, and limits placement to appropriate locations. Cameras in restrooms, changing rooms, break rooms, and other privacy-sensitive areas are prohibited.

Audio monitoring of employee conversations where the employer is not a participant raises more significant legal questions. Installing hidden microphones to capture employee conversations constitutes environmental interception, not participant recording, and carries criminal exposure under Article 10-A.

Email monitoring of company-provided accounts is permitted when the employer has a documented policy notifying employees that corporate email is for business use and is subject to review.

In all cases, the LGPD requires that employer monitoring be proportionate to a legitimate business purpose, documented in a data processing record, and communicated to employees in advance.

Call Centers and Decreto 11.034/2022

Call centers in Brazil face specific recording mandates under federal regulations. Decreto 11.034/2022 regulates the Serviço de Atendimento ao Consumidor (SAC) for companies providing services regulated by the federal government.

Article 12, Paragraph 3 of the Decreto requires that telephone call recordings made to SAC lines must be maintained for a minimum of 90 days from the date of service. During that period, the consumer has the right to request access to the full content of the recorded call.

Beyond the 90-day recording retention, the service record (registro do atendimento) must be kept available to the consumer and to regulatory authorities for a minimum of two years from the date the consumer's issue was resolved.

In practice, callers to Brazilian customer service lines hear an automated notice stating the call is being recorded. This notice reflects regulatory compliance and consumer protection best practices rather than a two-party consent obligation. The underlying recording is lawful under the one-party consent framework, and the Decreto adds specific retention and access obligations on top of that.

How Recordings Are Used as Evidence in Court

A lawfully obtained participant recording may be submitted as evidence in:

• Criminal proceedings (subject to the electoral exception noted above)
• Labor court proceedings (Justiça do Trabalho)
• Civil litigation (including family, contract, and tort cases)
• Administrative and regulatory proceedings

Courts assess the authenticity and integrity of the recording. Under Article 8-A of Lei 9.296/1996, also introduced by the Pacote Anticrime, the party submitting an environmental recording must be prepared to demonstrate its integrity. Metadata, chain of custody, and forensic analysis may all be relevant.

A manipulated or selectively edited recording can be challenged and excluded. Submitting an altered recording as genuine evidence may itself constitute a criminal offense.

Public Disclosure vs. Legal Evidence

Using a recording as evidence in court is distinct from sharing it publicly. A recording that is perfectly admissible in a legal proceeding may still create civil liability if shared on social media, posted online, or distributed to third parties.

Article 20 of the Brazilian Civil Code protects a person's right to their own voice and image. Public disclosure of a private conversation that causes harm to reputation, honor, or dignity may give rise to claims for moral damages (danos morais) and material damages, even if the original recording was lawfully made.

The practical guidance is straightforward: use recordings for their intended legal purpose. Sharing them widely without a clear legal justification is a separate action with separate consequences.

LGPD and Voice Recordings

The Lei Geral de Proteção de Dados (LGPD, Lei 13.709/2018) is Brazil's comprehensive data protection law. Modeled on the European Union's GDPR, it took full effect in 2020 and is enforced by the Autoridade Nacional de Proteção de Dados (ANPD).

Voice Recordings as Personal Data

The LGPD defines personal data as any information relating to an identified or identifiable natural person. A voice recording of a recognizable person qualifies. The LGPD applies whenever a business or organization collects, stores, processes, or shares voice recordings.

Voice recordings used for biometric identification, such as voiceprint authentication systems in banking or security applications, qualify as sensitive personal data under Article 5, Inciso II of the LGPD. Sensitive data receives heightened protection, and the legal basis of "legitimate interest" is not available for processing it. Consent or another basis from the restricted list in Article 11 is required.

Standard call recordings (customer service calls, sales interactions) are treated as ordinary personal data. The voice identifies the speaker, but the recording is not being used for biometric matching. Different legal bases are available for processing ordinary personal data.

Legal Bases for Processing Voice Recordings

Before collecting, storing, or processing voice recordings, a business must identify and document one of the legal bases provided in Article 7 of the LGPD:

• Consent: The data subject's free, informed, specific, and unambiguous agreement. Must be documented.
• Legal or regulatory obligation: Processing required by law. Call centers subject to Decreto 11.034/2022 fall here.
• Contractual necessity: Processing necessary to perform a contract with the data subject.
• Legitimate interest: The controller's legitimate interest, balanced against the data subject's fundamental rights. Available for ordinary personal data, not for sensitive data.
• Exercise of rights in judicial, administrative, or arbitration proceedings: Relevant when recordings are maintained as potential evidence.

ANPD Enforcement and Penalties

The ANPD has accelerated enforcement significantly since gaining full institutional autonomy through Provisional Measure 1.317/2025. The agency can now order establishments to cease operations, seize goods, and request police assistance when its functions are obstructed.

LGPD penalties include:

• Fines of up to 2% of the company's revenue in Brazil, capped at R$50 million per violation.
• Daily fines to compel compliance.
• Public disclosure of the violation.
• Blocking or deletion of personal data involved in the violation.
• Suspension of the relevant database or processing activity for up to six months (renewable).

Since 2023, the ANPD has issued over R$98 million in fines across sectors including healthcare, technology, and financial services. In 2025, the agency ordered Meta to suspend processing personal data for AI training, backed by a daily fine of R$50,000.

For businesses handling voice recordings, the enforcement message is direct: document your legal basis, provide notice, define retention periods, and respond to data subject access requests. The ANPD is actively auditing and penalizing organizations that fail to do so.

Data Subject Rights

The LGPD grants individuals the right to access, correct, delete, and port their personal data. A person whose voice was recorded may:

• Request a copy of the recording.
• Ask that the recording be deleted when no lawful basis for retention remains.
• Demand information about who has accessed the recording and for what purpose.

Businesses must define retention periods and enforce them. Keeping recordings indefinitely without a documented justification violates the LGPD's data minimization and purpose limitation principles.

Business Compliance Checklist

Companies operating in Brazil that record voice communications should take the following steps to stay on the right side of the law.

Identify and document your legal basis. Before recording a single call or meeting, determine which LGPD legal basis applies. Record that determination in your data processing register (registro de atividades de tratamento). Do not rely on informal assumptions.

Provide transparent notice. Although one-party consent does not legally require you to tell the other party about a recording, the LGPD's transparency principle requires businesses to inform individuals about how their personal data is collected and used. For customer-facing calls, an automated disclosure at the start of the call satisfies both practical and legal expectations.

Define and enforce retention periods. Establish a written policy specifying how long recordings are kept. For SAC call centers, the minimum is 90 days for the recording and two years for the service record under Decreto 11.034/2022. Beyond any regulatory minimum, recordings should be deleted or anonymized when the stated purpose for collection has been fulfilled.

Restrict access. Limit access to stored recordings to personnel with a legitimate business need. Maintain access logs. Voice data sitting in an unprotected shared drive is an ANPD enforcement action waiting to happen.

Respond to data subject requests. Build a process for handling LGPD access, correction, and deletion requests related to voice recordings. The LGPD gives the ANPD authority to impose daily fines for failure to respond.

Train your staff. Employees who handle recordings should understand what they can and cannot do with them. Forwarding a customer call recording to a personal email, sharing it on a group chat, or using it for unauthorized purposes creates legal exposure for the company.

Manage cross-border transfers. If recordings are stored or processed on servers outside Brazil, ensure the transfer complies with the LGPD's international data transfer rules. Options include standard contractual clauses, binding corporate rules, or transfer to a jurisdiction that the ANPD has recognized as providing adequate protection.
