Katharine Hepburn – Guide to Filing an INSS Social Security Petition

Filing a social security lawsuit against Brazil’s National Social Security Institute (INSS) begins with a document known as the petição inicial – the initial petition. This procedural piece must comply with the Code of Civil Procedure (CPC), include all indispensable documents, and be electronically submitted through the court’s digital system. In practice, the platform varies: some Federal Court branches use e-Proc, while others operate with PJe. Despite the interface differences, the core logic of registration, document attachment, and correct subject classification remains consistent across systems.

The petition is the gateway to judicial review of an INSS denial or delay. Understanding its required elements, the proper court, and the electronic submission steps is essential for any attorney or public defender handling a social security claim. The following sections break down the official requirements, typical structure, and practical considerations drawn from court manuals and legal models.

What does the initial petition need to contain?

Essential elements at a glance

Key insights from official sources

• The petition must be signed by a lawyer or public defender; the common procedure of the Federal Court of the 2nd Region does not accept self-representation.
• In the Federal Special Court (JEF), the jus postulandi (right to petition without a lawyer) is allowed only in specific hypotheses.
• All indispensable documents must be digitized, attached electronically, and digitally signed according to the tribunal’s local rules.
• The subject classification in the court registration system must be as specific as possible to ensure correct routing.
• If the petitioner faces difficulties without a lawyer, the 2nd Region Federal Court provides support through its initial assistance sector.
• Many model petitions include a request for tutela de urgência (emergency relief) when there is a risk of harm or immediate need for benefit implementation.

Fact table: Documents commonly required

How is a typical social security action structured?

Addressing to the competent court

The petition begins with the endereçamento – the formal address to the competent judge. This must indicate the correct forum based on the plaintiff’s domicile and the nature of the claim. In general, social security actions against INSS fall under federal jurisdiction, as detailed in the overview of social security claims.

Identification of the parties

Next comes the qualificação of the plaintiff (author) and the defendant (INSS). Full personal data, profession, and address are required. The defendant is identified as the Instituto Nacional do Seguro Social, a federal autarchy.

Facts: contribution history and administrative denial

The fatos section narrates the plaintiff’s contribution or labor history, the date of the administrative benefit request, and the INSS decision – usually a denial. If no prior administrative request exists, the reasons for bypassing it must be explained.

Legal grounds

Fundamentos jurídicos lay out the applicable social security theory. This includes citing the relevant law, such as Law 8.213/91, and the specific benefit being claimed – e.g., retirement by age, disability pension, sickness benefit, accident benefit, or survivor’s pension. The full text of Law 8.213/91 is available at the official Brazilian government portal.

What documents are normally required?

According to the materials consulted, the following documents form the common basis for any social security action:

• Procuração (power of attorney)
• Personal documents such as RG, CPF, and proof of residence
• Complete CNIS (National Social Information Registry)
• Administrative process and the INSS decision or denial
• Medical reports, PPP, certificates, and other material evidence appropriate for the claimed benefit

What are the rules of court registration and subject classification?

When registering a social security case, the attorney must select a subject code that accurately reflects the nature of the claim. The assunto field in the electronic system determines routing and assignment. Codes range from benefit-specific categories to procedural classifications. The guide to Brazilian court procedures offers a practical walkthrough of this step.

The electronic platforms e-Proc and PJe both require the same core data: plaintiff and defendant details, subject code, document list, and the petition itself. Each platform publishes its own user manual; the INSS official website also provides supporting resources for attorneys and citizens.

For those who need model petitions or checklists, the Maria Teixeira Adv portal offers a detailed template library. Similarly, the Ialocus resource platform includes step-by-step guides and document lists tailored to each type of social security benefit.

In summary, the initial petition is the cornerstone of any social security lawsuit against INSS. Meeting the legal, documentary, and procedural requirements from the outset increases the chances of a swift and favorable judicial review. Attorneys and public defenders should consult the official court manuals and model petitions regularly, as procedural rules and digital platform interfaces may evolve.
