Legal software for lawyers in Brazil in 2026
Which Brazilian courts Custodio Legal checks over e-SAJ, which judicial channel it can't read 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 the courts that publish their lookup over e-SAJ, measured directly at the Tribunal de Justiça de São Paulo (TJSP).
- 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 Central Bank's PTAX rate, as an informative reais figure under the USD price.
- The LGPD deadline. Fifteen calendar days for the five rights the law recognizes, counted against article 19 itself.
- 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
- DJEN intimações. The Diário de Justiça Eletrônico Nacional returns a CloudFront 403 to anything outside Brazil, measured from both of the product's origins — Bogotá and the infrastructure the binary runs on. No region switch fixes this today.
- 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 legal-citation map. The map that resolves a Brazilian statutory citation to its text hasn't been built yet.
- 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 a court that publishes over e-SAJ, 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?
The ones that publish their case lookup over e-SAJ, measured at the Tribunal de Justiça de São Paulo (TJSP). 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?
No. The Diário de Justiça Eletrônico Nacional returns a CloudFront "blocked from your country" response from both origins the product uses today — it's a geographic block from the source, not a technical gap on Custodio's side.
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.
