What should teams do about Legal Bases under the Brazil LGPD?
Classify the data before selecting from a list. Ordinary personal data may rely on one of Article 7's ten bases: consent; compliance with a legal or regulatory obligation; public-administration processing for laws, regulations, contracts, agreements, or public policies; research by a research body with anonymization where possible; performance of a contract or preliminary procedure requested by the data subject; regular exercise of rights in judicial, administrative, or arbitral proceedings; protection of life or physical integrity; health protection by health professionals, health services, or health authorities; legitimate interest; or credit protection.
Article 11 permits sensitive-data processing with specific and prominent consent for specific purposes, or without consent when the processing is indispensable for one of its stated cases: legal or regulatory compliance; shared processing by public administration for public policies; research with anonymization where possible; regular exercise of rights, including in contracts and proceedings; protection of life or physical integrity; health protection by the authorized health actors; or fraud prevention and data-subject security in electronic identification and authentication, subject to the statutory protections and the data subject's rights prevailing where applicable.
Match the facts to every condition. A contract basis covers performance or a preliminary step requested by the person, not unrelated advertising. Legal obligation requires an identifiable binding duty, not a preference or customer contract. Vital protection is for life or physical integrity, not routine convenience. Credit protection follows applicable law and remains subject to LGPD principles.
Consent is one basis, not a default or a cure. The controller must be able to prove a free, informed, unambiguous, purpose-specific choice; written consent must be prominent; generic authorizations are void; and withdrawal must be free and facilitated. Sensitive-data consent has the additional Article 11 requirement that it be specific, prominent, and for specific purposes.
A lawful basis does not make all subsequent use lawful. Apply purpose adequacy, necessity, transparency, security, data-subject rights, retention limits, and accountability. Data made manifestly public by the person does not remove the LGPD principles or rights, and a cross-border transfer still needs a separate Article 33 mechanism.
- Owner: describe one sufficiently specific purpose, the affected people, the data and whether it is sensitive, the collection source, recipients, retention, and decision-maker.
- Decision: record the exact Article 7 or 11 paragraph, each condition and supporting fact, why the data is necessary, and why a narrower alternative would not meet the purpose.
- Implementation: align the notice, collection fields, access, sharing, retention, rights workflow, consent control where used, and international-transfer mechanism with the recorded decision.
- Review: reassess before a new purpose, sensitive inference, new recipient, product or contract change, public-data reuse, automated decision, transfer, or material change to a consent choice.
Articles 7, 10, and 11 provide the legal bases for ordinary and sensitive personal data and the conditions for legitimate interest.
