The migration process initiated by the Court of Appeals of the State of São Paulo (TJSP) from the Electronic Court Automation System (eSAJ) system to the Eproc system has been underway since March 31, 2025, as announced through Joint Statement No. 200/25. What, at first glance, may seem like a simple interface change, in practice, represents a paradigm shift in the manner this institution’s legal proceedings are accessed, filed, monitored, and managed.

The transition will be made gradually, according to an implementation schedule that may extend over a period of up to five years. Yet, it will require fast-paced adaptation from offices, legal departments, and companies whose volume of pending cases makes the task of managing deadlines, hearings, orders, and statements more complex.

The migration complies with the Brazilian guideline for standardizing procedural systems, coordinated by the Brazilian Council of Justice (CNJ), which has been encouraging courts to adopt more agile, modern, and interoperable technological solutions. Eproc is one such solution—a lightweight, intuitive system with a user-friendly interface and features that eliminate dependency on Java plugins and subscriptions, easing access from any browser and device.

Furthermore, the adoption of Eproc tends to reduce operational costs, increase service stability, and more efficiently integrate the bodies of the Judicial Branch.

Developed by the Regional Federal Appellate Court of the 4th Region approximately 15 years ago and perfected for the reality of the State Judicial Branch by the Courts of Appeal of Rio Grande do Sul and Santa Catarina, Eproc is currently used by 14 courts of the State, Federal, and Military Justice. These courts, which include, in addition to those already mentioned, the TJRJ and the TJMG, account for 60% of the currently pending cases in Brazil.

The main result is the need to relearn procedural flows. Filing, tracking, document attachment, and notification tools work differently in Eproc. It is essential that internal systems, automation, legal teams, and even outsourced partners are fully adapted to the new environment.

Another relevant change: processes pending in eSAJ will remain in the old system, while new ones, according to the court’s schedule, will be filed directly in Eproc. This will require simultaneous mastery of two systems during the transition period.

Without proper preparation, there is an actual risk of missing deadlines, errors in filing case record, duplication of controls, and confusion in the cases pendency. Law firms that handle a high volume of cases or companies that outsource their litigation should pay extra attention.

With the migration of TJSP to the Eproc system, there were also changes in the issuance of civil certificates of lawsuits filed. Previously, these certificates were made available exclusively through the eSAJ system, referred to as “Civil Certificate of Lawsuits Filed up to 10 years” or “more than 10 years”.

Now, eSAJ only issues the “General Civil Certificate of Lawsuits Filed – SAJ SGC“, which, in turn, needs to be supplemented with a new certificate issued by Eproc, referred to as “Judicial Districts and Appeals Panels (Trial Court) – Civil”.
