Imagine you're in the office and a new client, Mrs. Elza, arrives in despair. She's retired, 62 years old, and has discovered that her name has been added to the Serasa blacklist due to a debt of R$ 12.000,00, related to a personal loan agreement with a financial institution.
The problem is that she never signed that contract.
Dona Elza's name was used fraudulently. Someone forged her signature, inserted real personal data into an electronic contract, and thereby obtained the credit improperly.
As the lawyer representing the case, you will need to file a declaratory action of nullity of the legal transaction, with a request for urgent provisional relief to remove her name from the defaulters' registers.
And to do this safely, it's essential that you understand how the legal process is structured, from the initial petition to the final judgment.
Let's understand this path?

The starting point: the initial petition.
The first step will be to draft the initial petition. It is this document that initiates judicial activity and begins the process of establishing facts, according to Article 2 of the Code of Civil Procedure.
In the case of Dona Elza, it will be necessary to formulate the following main requests:
- Declaration of nullity of the loan agreement;
- Compensation for moral damages (due to wrongful registration);
- Anticipation of the effects of the injunction for the immediate removal of the name from Serasa.
To do this, you must fulfill the requirements of article 319 of the CPC: identify the parties, state the facts and legal grounds (absence of consent, article 104, I of the Civil Code), formulate the requests, indicate the value of the case, request evidence, express your opinion on a conciliation hearing, and include the necessary documents.
It is in the initial petition that the lawyer defines the contours of the claim. And this is essential, because the judge will be bound by what was requested (articles 141 and 492 of the CPC). In other words, the judge cannot go beyond this, nor decide something different from what was requested.
What does the judge do upon receiving the petition?
Suppose you file the lawsuit on a Monday. The case is assigned and falls to a judge in the 3rd Civil Court.
At this point, the judge will analyze the formal aspects of the petition, and may:
- Determine the amendment, if any formal requirement is missing (art. 321);
- Dismiss summarily if the initial pleading is inept, lacks standing, or is manifestly unfounded (art. 330);
- Dismiss the request summarily if there is a binding precedent that already resolves the issue (art. 332);
- Receive the petition and order the summons of the defendant, if everything is in order.
Of course, for the judge to accept the initial pleading, it needs to be technically well-constructed. It is necessary to articulate the requests well, organize the legal arguments, and provide the case file with supporting documents that substantiate the right being invoked.
In the case of Dona Elza, for example, imagine that you presented the police report, the certificate of no debts, the proof of residence, the printouts of the negative credit report, and described the facts clearly, showing that there was document fraud.
Of course, if you are, or intend to be, an IDP student, you can probably already imagine what's coming next.
The judge granted the provisional injunction, ordering the immediate removal of her name from the defaulters' registers and ordering the bank to respond.
The defendant's summons and the right to a fair hearing.
The summons is the act that calls the defendant to the proceedings, ensuring their right to a fair hearing (article 238 of the CPC). In civil proceedings, the summons is essential for the validity of the process. That is, without it, the procedural legal relationship is not formed.
Furthermore, the valid quote:
- This puts the debtor in default;
- Interrupts the statute of limitations (art. 240);
- It leads to lis pendens and prevents the judgment from taking place.
Whether the summons is served by a court officer or by registered mail with return receipt requested depends on the initial option chosen in the petition.
In the case of financial institutions, electronic means are generally used (art. 246, §1º).
Conciliation or mediation hearing: when it (doesn't) happen
After the summons, the CPC provides for the possibility of a conciliation or mediation hearing (art. 334).
If neither party objects, the judge may appoint one with the aim of seeking a settlement.
In Dona Elza's case, a settlement is unlikely, since the bank will deny the fraud and maintain the validity of the contract.
Therefore, you can expressly state in the initial petition that you waive the hearing.
This avoids the designation of an unnecessary act and the process goes directly to the contestation stage.
Response: the defendant's defense
The bank will then be notified to present its defense within 15 business days (art. 335).
In it, they will likely claim that the contract was validly signed digitally, that it was accepted via the client's mobile phone, and that all documents are in compliance.
But this is where technique comes in, because it is necessary to observe whether the challenge fulfills the specific rebuttal of the facts (art. 341) and whether the evidence presented is truly robust.
On the other hand, the defense may raise preliminary issues, such as lack of jurisdiction, lack of standing, or lack of interest in bringing the action, which the judge will have to address in the next stage.
Process streamlining
Once the contestation phase is over, the judge will issue a procedural order (art. 357). Here, he resolves the preliminary issues, delimits the points of contention (for example, whether or not the plaintiff signed) and defines the means of proof to be produced.
At this stage, a hearing for instruction and judgment may be scheduled, especially if there is a need to hear witnesses or collect personal testimony.
In cases of fraud, it is common for the judge to allow for forensic handwriting analysis or analysis of the IP records of the digital signature. Knowing how to handle this phase well is crucial for preparing the ground for the judgment.
Evidentiary instruction
Imagine that the judge grants the request:
- Forensic handwriting analysis (to analyze signatures);
- Testimony from two witnesses for the plaintiff;
- Personal testimony of a bank representative.
The preliminary hearing and trial will be scheduled, and after it takes place, the judge will set a deadline for the submission of final arguments in writing.
This is where the process matures towards a decision. All the evidence has been gathered, and now the judge has the necessary elements to make a confident ruling.
Judgment: judgment on the merits
Finally, the judge delivers a sentence (articles 485 and 487 of the CPC).
In the case of Dona Elza, suppose the judge recognizes the lack of consent, declares the contract null and void, and orders the bank to pay R$ 5.000,00 in moral damages.
The sentence will contain:
- Concise report;
- Justification (with analysis of the facts and the law);
- Device (with the conclusion and effects of the decision).
If the judgment is on the merits, it can generate res judicata, making the decision immutable and indisputable.
Final judgment: the stabilization of the decision.
If the bank does not appeal — or if the appeal is rejected — the judgment becomes final. From that moment on, the matter is considered res judicata (art. 502), and the decision becomes definitive.
The winning party may initiate enforcement proceedings (article 513 et seq.), requesting payment of compensation.
It is important to remember that even after a final and unappealable judgment, the decision may be unenforceable if it contradicts a rule subsequently declared unconstitutional by the Supreme Federal Court (article 525, §12), or if it is subject to a rescissory action (article 966), in exceptional cases.

The process as a strategic tool
Contemporary legal practice no longer allows for decisions to be made in the dark.
From choosing the type of legal action to structuring the technical defense, including defining the claims, delimiting the points of contention, handling the evidence, and interpreting precedents, everything demands technical preparation, critical reading, and procedural decision-making skills.
In Dona Elza's example, we saw how well-targeted action, right from the initial petition, can make all the difference: preliminary injunction granted, well-defined request, concise documentation, and a favorable judgment.
But to reach that level of security, it takes more than knowing the cold letter of the law; it requires mastering the language of the process.
That is why continuing education, especially at the postgraduate level, becomes a real differentiator for professionals who want to establish themselves solidly in the legal market.
The specialization in Civil Procedural Law at IDP was designed precisely for this purpose. The goal is to train professionals capable of combining theory and practice in depth, engaging with court case law and maturely addressing the challenges of modern civil law practice.
