Rio Bar Asks to Join São Paulo Lawsuit Over Enter’s Legal AI Platform
The Rio de Janeiro section of the Brazilian Bar Association (OAB-RJ) asked a federal court on Friday, October 9, to join the São Paulo section’s lawsuit against Enter, a legal AI startup, as a co-plaintiff. The public civil action, brought by OAB-SP against Talisman AI Ltda., the company behind Enter, is before the 4th Federal Civil Court of São Paulo, OAB-RJ said in a statement.
OAB-RJ fully adopts São Paulo’s arguments, evidence and requests without adding new claims. It argues that the dispute has national reach, because companies using the platform operate across Brazil and appear in cases before Rio’s state, federal and labour courts. According to the original complaint, Enter offers case analysis, strategy recommendations and the drafting of legal documents at scale, which OAB-SP says amounts to acts reserved for lawyers being performed by a company not registered with the Bar, weakening the role of the responsible lawyer.
OAB-SP filed the suit on Wednesday, October 7, and is seeking R$ 1 million in collective moral damages, ias.news reported. The Bar wants effective human supervision of strategy and drafting, identification of the lawyer who reviewed each AI-assisted document, a guarantee that lawyers can reject drafts suggested by the platform, protection of professional secrecy and compliance with the LGPD data protection law, along with audits, traceability and preserved records of how drafts were generated and reviewed. OAB-RJ president Ana Tereza Basilio said the section does not oppose artificial intelligence or new technology in legal practice, but that such tools must stay subordinate to the lawyer’s work, responsibility and technical independence.
What it means in practice
Enter disputes the case. In a statement to the outlet Startups, cited by ias.news, the company said the suit rests on mistaken information and unfounded accusations, that review, signature and filing of documents stay with licensed lawyers hired by its clients, and that it complies with the LGPD and does not use client data to train models. Founded in 2023, Enter became a unicorn after a R$ 500 million Series B that valued it at US$ 1.2 billion.
The case could become a reference point for AI vendors in regulated professions while Brazil’s AI legal framework still awaits a Chamber vote. Questions about data handling also fall within the remit of the ANPD, which is building an internal AI centre and preparing a second sandbox.
What to watch: whether the court admits OAB-RJ to the case, how it rules on São Paulo’s requests for preliminary measures, and whether the OAB Federal Council, which Enter says it is talking to, issues national guidance on AI in legal practice.
