Legal software for lawyers in Brazil in 2026
Which Brazilian courts Custodio Legal checks over e-SAJ, how it brings in DJEN comunicações, which source it doesn't query and why, and what the AI does with that as its input.
Custodio Legal operates in seven countries today, each behind its own plugin — what a plugin declares it supports is the only thing the platform promises there. In Brazil, what's sold is AI that answers over your own documents with a verifiable citation; the daily CNJ-number check is the input. This page states, with its source, how far that input reaches.
What Custodio watches in Brazil
- e-SAJ, by court. Custodio checks the unified case number at three courts whose e-SAJ lookup is open and measured: the Tribunal de Justiça de São Paulo (TJSP), the Tribunal de Justiça do Amazonas (TJAM) and the Tribunal de Justiça do Acre (TJAC). A case from any other court can still be added, but its number isn't checked.
- DJEN comunicações. Custodio queries the Diário de Justiça Eletrônico Nacional by the CNJ number of the cases you follow, in a daily pass spread across them that covers the last seven days; each comunicação comes in as an entry on the case, with its text. On the DJEN it doesn't search by OAB number or party name.
- The CNJ number's check digit. Not just the shape: Custodio computes and verifies the Módulo 97 Base 10 of ISO 7064:2003 that CNJ Resolução 65/2008 itself publishes.
- The article 219 CPC calendar. Procedural deadlines are counted in business days only, with the nine national holidays.
- Party search in three modes. Name or corporate name, CPF or CNPJ, and OAB number — not the lawyer's name, which doesn't come back in time with a common surname.
- The price in reais. Plans are charged in reais, at the figure the price list publishes and with no conversion in between.
- The LGPD deadline. Fifteen calendar days for the five rights the law recognizes, counted against article 19 itself.
- Legal citations, linked to their source. In the documents you upload, Custodio recognizes citations of federal statutes — "Lei nº 13.105/2015", "art. 219 do CPC", "CLT" — and links them to their text on LexML. State and municipal law is left out, and a citation it doesn't recognize goes to a LexML search, never to a guessed link.
- AI over your own documents. It answers with the source document cited for each answer, summarizes the ruling, states where the case stands, and drafts a filing in Word.
What is still out of scope
- DataJud. Its terms of use forbid commercial use, and Custodio doesn't query it even for test data while that condition stands unchanged in writing.
- A verified bar registry. The OAB publishes its roll, but the national consultable registry is an application Custodio hasn't yet been able to read reliably — the state is "not evaluable," not "doesn't exist."
How to try it before deciding
- Create the free account, no card, and add a real case from the TJSP, the TJAM or the TJAC, with its full CNJ number.
- Wait for the first automatic check and see whether it brought back anything from the case's history, not only what happens from now on.
- Upload a document from the file and ask the system something specific — the answer has to cite which document it came from.
- Compare the published price against how many open cases you carry today: the free plan includes 15 open matters.
Frequently asked questions about legal software in Brazil
Which courts does Custodio watch in Brazil?
Three, whose e-SAJ case lookup is open and measured: the Tribunal de Justiça de São Paulo (TJSP), the Tribunal de Justiça do Amazonas (TJAM) and the Tribunal de Justiça do Acre (TJAC). Coverage is by court, not "Brazil" as a whole — saying it any other way would be a promise the product can't back up.
Does Custodio watch DJEN intimações?
Yes, by the CNJ number of the cases you follow: a daily pass is spread across your cases, covers the last seven days and brings in each comunicação with its text as an entry on the case. On the DJEN it doesn't search by OAB number or party name. The comunicação that counts is the official one on the DJEN: Custodio tells you what it finds, it doesn't replace your own check.
Does Custodio query DataJud?
No, not even for test data. DataJud's CNJ terms of use forbid commercial use, and Custodio doesn't query it while that condition stands.
