BacenJud Effect: How Brazilian Courts Attach Bank Accounts

The BacenJud Effect: BacenJud SISBAJUD Brazil Bank Account Attachment Explained

Your Brazilian debtor has a very sophisticated cash management strategy: empty the account every time the creditor looks like they might show up. Brazil built a judicial robot to handle exactly this problem. Her name is Teimosinha, and she runs SISBAJUD, the national asset attachment system that replaced BacenJud in August 2020.

You agree the old BacenJud model had a flaw: debtors learned to time their balances around it. We promise this guide will show you how SISBAJUD and Teimosinha closed that gap, and how a foreign creditor actually reaches them. Preview: one statute, one robot, one STJ gatekeeper, and one narrow carve-out that surprises most foreign counsel.

What is SISBAJUD and how does it work?

SISBAJUD stands for Sistema de Busca de Ativos do Poder Judiciário. It is the electronic bridge between a Brazilian judge and every financial institution authorised by Banco Central do Brasil. When a creditor holds an enforceable title and opens an execution proceeding, the judge can transmit an attachment order through SISBAJUD, and Banco Central fans it out to banks, credit unions, brokerages, and investment firms at once.

The statutory engine is Article 854 of the Código de Processo Civil. It lets the judge order the block inaudita altera parte, meaning without prior notice to the debtor. That detail is the entire point. If the debtor knew the order was coming, the balance would be zero by the time it arrived.

CNJ launched SISBAJUD in August 2020 jointly with Banco Central and the Procuradoria-Geral da Fazenda Nacional. It replaced the older BacenJud 2.0 system, which is why practitioners still refer colloquially to "the BacenJud effect" when they mean the combined historical and current attachment power of Brazilian courts over bank balances.

How long does a SISBAJUD block take?

From the moment a judge clicks send, Banco Central typically transmits the order to every covered financial institution within a day. Responses from the banks usually land inside 24 hours. Under the pre-2021 model, that snapshot was basically the whole game. If the debtor had cash in the account at that moment, it was frozen. If not, the creditor got nothing and had to try again later.

That one-shot structure is what Teimosinha killed.

What is Teimosinha in SISBAJUD?

Teimosinha means "the stubborn one" in Portuguese, and she does not leave until she gets paid. CNJ announced the feature in February 2021 and made it operational at the end of April 2021. Teimosinha takes the judge's original attachment order and re-runs it automatically, every business day, for up to 30 consecutive days, extendable by the judge to 60.

Every time fresh money hits the debtor's account, the sweep catches it and blocks it up to the amount owed. This is the feature that SISBAJUD 3.0 extended further with continuous, so-called permanent, blocking functionality. Foreign guides still describe Brazilian attachment as a single freeze. It has not been a single freeze for five years.

Teimosinha: the 30-Day Robot and Her Single Blind Spot

Here is the information most English-language explainers miss. Teimosinha is not an event. She is a rolling process. The judge issues one order, and the system keeps executing it against the debtor's balances for a window of 30 days by default, extendable to 60.

The good news is that Brazil built a judicial robot to handle exactly the drain-the-account tactic. The better news is that she runs for up to 60 days, which is long enough to catch almost any operating business's next payroll cycle, receivables deposit, or client payment.

Now the blind spot. The Tribunal de Justiça de São Paulo has held that Teimosinha cannot be deployed against a company under judicial reorganisation (recuperação judicial). Brazilian insolvency policy treats funds in a reorganising entity as protected from individual creditor sweeps, because those funds are earmarked for the court-supervised restructuring plan. So if your debtor has filed for recuperação judicial before the order lands, the rolling sweep is off the table. A one-off block may still be considered by the reorganisation court, but the stubborn robot is not coming through that door.

The practical lesson for a creditor is to check the debtor's insolvency status before celebrating. SISBAJUD plus Teimosinha is a weapon of extraordinary reach against a solvent debtor who is simply avoiding payment. It is not a workaround for an insolvency process.

The Foreign Creditor Pathway: From Overseas Judgment to SISBAJUD

Foreign creditors do not get to walk into a Brazilian execution court with a London or New York judgment and ask the judge to press send. There is a gate, and it is called the Superior Tribunal de Justiça. Here is the sequence.

1. Homologate the foreign judgment at the STJ. Under Código de Processo Civil Arts. 960 to 965, and Art. 216-A and following of the STJ Internal Rules, any foreign judgment must first be recognised (homologated) by the Superior Tribunal de Justiça before it has any effect inside Brazil. This is a dedicated proceeding, with its own procedural timeline, where the STJ checks formal requirements, service of process, finality, and public policy compatibility.
2. Open cumprimento de sentença in federal court. Once the STJ grants homologation, the foreign judgment is treated as an enforceable title inside Brazil. The creditor then files an execution proceeding in the competent federal court, typically where the debtor is domiciled or holds assets.
3. Request the SISBAJUD order under CPC Art. 854. With the execution open, the creditor asks the judge to transmit an attachment order to Banco Central. From here the mechanics are identical to any domestic case: electronic order, simultaneous query of all financial institutions, Teimosinha sweep for up to 60 days.

For foreign arbitral awards the pathway is very similar. Brazil ratified the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards through Decreto 4.311/2002, and the STJ is again the homologation gatekeeper. Once the award is homologated, the creditor proceeds to federal execution and can request SISBAJUD in the same way.

How InterStation Handles a Brazilian Claim

1. Title review. We audit your contract, invoices, and any existing judgment or arbitral award to confirm it is the right raw material for Brazilian enforcement.
2. STJ homologation filing. Our Brazilian counsel prepares and files the homologation petition with certified translations and consular or apostille legalisation where required.
3. Execution proceeding. Once homologation is granted, we open cumprimento de sentença in the competent federal court and draft the CPC Art. 854 request.
4. SISBAJUD plus Teimosinha deployment. The judge transmits the attachment order, and we monitor the rolling sweep day by day for the full 30 to 60 day window.
5. Collection and remittance. Captured funds are unblocked to the creditor, converted if needed, and remitted under Banco Central's foreign exchange rules.

If you have an unpaid Brazilian counterparty and a title worth enforcing, the BacenJud effect is still alive under SISBAJUD, and Teimosinha is still running her 60-day shift. We translate that into captured funds.
