As of August, 2026, the Brazilian Bar Association – São Paulo Chapter (OAB-SP) will require that all corporate acts of law firms be filed exclusively by digital means. The measure is part of the entity’s Digital Transformation Program and promises to streamline service; on the other hand, it tends to introduce a new layer of complexity for offices that are not familiar with the particularities of registration with the Bar Association.
Anyone who has gone through a similar process in other states knows that the transition to an electronic system does not always go smoothly. In Rio de Janeiro, the implementation of a similar system generated operational instability, with access difficulties, unexpected requirements and delays that directly affected the regularity of several companies.
OAB is not the Board of Trade
Any corporate act that involves a company whose purpose includes the provision of legal services, even if among other activities, must be registered with the OAB, and not with the Board of Trade. This is because the registration with the Bar Association confers legal personality to the law firm, in the same way that the Board of Trade does for business companies in general.
The process, however, is more similar to that of notary offices than to that of boards of trade: the process is conducted directly by the OAB, with the submission of documentation, analysis by the entity’s technicians and a response by email informing the approval or the need to comply with requirements.
What changes from August 2026 regarding the registration of law firms with the OAB?
With the change, OAB-SP now accepts the filing of corporate acts exclusively through the entity’s portal, but four types of acts will remain subject to the in-person filing, as follows:
- Branch opening and closing;
- Association between companies;
- Termination due to death; and
- Transformation from a simple partnership to a law firm.
The structure adopted follows the electronic application model used by several boards of trade, a system that requires the detailed completion of information and the upload of specific documents before authorizing the constitution or amendment of any corporate act.
Where does the company registration process typically get stuck at the OAB?
The experience accumulated with the digital system in other states reveals that the main point of attention is the accuracy of the information provided. The system requires data that goes beyond the corporate document itself: among them, the exact composition of quotas of each partner who enters or leaves the company, information that needs to be stated in a structured way in the system.
Another element is the registration status of the partners themselves, as the OAB verifies, at the time of analysis, that all lawyers in the company are up to date with their individual fees. Pending issues in this field block the process and generate notification of requirement, which may delay operations that depend on the regularization of the corporate structure.
The procedure also varies according to the type of act: the procedure for recording the minutes of a meeting, for example, follows a different path than the one that applies to a contractual amendment, and confusing the flows is one of the most common causes of rework in the electronic environment.
The lesson of Rio de Janeiro
When OAB-RJ implemented its digital filing system, the transition period was marked by technical instabilities, doubts about the required documentation and difficulties in adapting users to the new system requirements. OAB-SP itself experienced a similar situation throughout 2025, when unavailability of the system led the Commission Firms Commission to adopt exceptional physical filing procedures, with deferral of the payment of fees.
These episodes illustrate the learning curve that, when not anticipated, results in accumulated demands, missed deadlines and the need to redo protocols already submitted.
What it takes to operate safely in the new environment
Navigating efficiently in the OAB electronic system requires technical knowledge that goes beyond reading the articles of association. It is necessary to understand the flow of each act, the documents required for each situation, the information that the system demands in a structured way and the analysis criteria that the Law Firms Commission applies in verifying the requests.
The lack of knowledge of these details, especially at a time of system transition, has repeatedly generated cycles of requests and follow-up that could be avoided with proper instruction on the process from the beginning.
PLBrasil Paralegal acts in the conduct of corporate acts of law firms, from the preparation and instruction of documents to the monitoring of the filing and the fulfillment of any requirements, with a focus on reducing rework, ensuring compliance with the criteria of the Bar Association and ensuring predictability within the deadlines.
