Cartório JK

What Cartório JK does

Cartório JK, legally known as 1º Ofício de Notas e Protesto de Títulos de Brasília (CNPJ 21.320.298/0001-97), is a delegated notary office operating in Asa Sul, Brasília, Brazil. Originally established with Maurício Gomes de Lemos as the first tabelião, the office was rebranded to Cartório JK in 2015 under the current tabelião, Mc Arthur Di Andrade Camargo, as a tribute to Juscelino Kubitschek. The office employs 101–250 staff and offers a comprehensive portfolio of notarial services including Hague Apostilles (Apostilamento da Haia), estate inventories (Inventário), property deeds (Escrituras de Compra e Venda, Doação, União Estável), extrajudicial divorce, powers of attorney, wills, notarial certificates (Ata Notarial), title protests, signature recognition, and document authentication.

The underlying technology stack is built around Brazil's national notary digital infrastructure: the e-notariado platform and ICP-Brasil certificates enable remote electronic notarial acts and digital signatures; E-Not Assina provides notary-recognized electronic signatures; SimplyBook powers online appointment scheduling; and the Apostil platform handles electronic apostille processing. Service delivery spans physical office visits, online booking, email/mail-based intake (notably for international apostille), and fully remote electronic signing. Quoted processing benchmarks include 24-hour inventory completion and 12-hour apostille turnaround.

The business model is entirely transactional, generating revenue through regulated government fees (emolumentos) set by the TJDFT Tabela de Custas, with no publicly disclosed pricing or revenue figures. Customers are primarily individual consumers (heirs, property buyers/sellers, divorcing couples, individuals needing international document legalization) and SMBs requiring legally valid documentation. The office operates under oversight from TJDFT, CNJ (including Provimentos 88 for AML and 100 for e-notariado), and COAF, and holds LGPD compliance certification with a designated DPO.

Scale indicators2 records

Recent moves6 records

Expansion highlights3 records

Emerging players

• PenPal World: Digital notarization and apostille platform focused on cross-border document legalization. Overlaps with Cartório JK's apostille service line and remote electronic signature offering, particularly for clients needing international document validation.

Others

• Veriff: Identity verification platform used by regulated service providers for KYC and AML compliance. Comparable to Cartório JK's compliance infrastructure (COAF, CNJ Provimento 88, LGPD), as both operate at the intersection of identity verification and regulated service delivery.

Regional players

• Arquivei: Brazilian document and certificate management platform that automates retrieval of federal, state, and municipal certificates. Comparable to Cartório JK's broader notarial and authentication offerings, both serving Brazilian businesses needing official document services with a digital-first approach.
• JusBrasil: Brazilian legal information and document platform providing access to jurisprudence, legislation, and official records. Comparable to Cartório JK's authentication and document certification services for Brazilian consumers and legal professionals seeking trusted public records.

Direct peers

• Notarize: US-based remote online notarization platform enabling electronic document signing with notary certification. Highly comparable to Cartório JK's E-Not Assina and e-Notariado services, addressing the same use case (notarized digital signatures) via a technology-led delivery model.
• NotaryCam: Remote online notarization provider that connects users with notaries via video for electronic document execution. Comparable to Cartório JK's electronic notarial acts and e-Not Assina offering in product category, customer base (legal and real estate), and digital delivery mechanism.

Broad incumbents

• DocuSign Notary (formerly DocVerify): Digital notary and electronic signature offering within a larger agreement cloud. Comparable to Cartório JK's e-Not Assina electronic signature service in product functionality and target customer segment.
• DocuSign: Global electronic signature and agreement cloud platform. Comparable to Cartório JK's E-Not Assina and electronic notarial acts offering, though DocuSign operates at much broader scale and serves corporate customers across many use cases beyond notarization.
