We've compiled the most common questions to help you better understand how our platform works.
Yes, absolutely! Digital and electronic signatures have full legal validity in Brazil.
Provisional Measure No. 2.200-2/2001 establishes the Brazilian Public Key Infrastructure (ICP-Brasil), while Law No. 14.063/2020 specifically regulates the use of electronic signatures.
Together, these laws guarantee the authenticity, integrity, non-repudiation, and legal validity of electronically signed documents.
An electronic signature is a broad concept that encompasses any form of signature performed by electronic means, including simple methods like clicking to accept terms.
A digital signature, on the other hand, is a specific and more sophisticated category that uses asymmetric cryptography and digital certificates issued by accredited certification authorities (such as ICP-Brasil).
Digital signatures offer a higher level of security, verifiable authenticity, and presumption of truthfulness, and are recommended for documents of greater legal criticality.
Yes! Digital signatures made through Signater are recognized internationally, complying with the main global legislation:
In the European Union, we align with the eIDAS regulation. In the United States, we follow the ESIGN Act and UETA.
This ensures your documents signed on Signater have legal validity in international transactions with countries around the world.
Yes! You can sign real estate contracts, leases, purchase and sale agreements, and other complex contracts using Signater with full legal security.
For higher-value or more complex contracts, we recommend using digital signatures with ICP-Brasil certificates (e-CPF or e-CNPJ), which provide the highest layer of security and presumption of truthfulness.
Signater supports both advanced electronic signatures and qualified digital signatures.
In the event of a legal dispute, digital and electronic signatures made through Signater are fully admissible as evidence in court.
Brazilian legislation (especially Art. 10 of MP 2.200-2/2001 and Law 14.063/2020) expressly recognizes the validity and evidentiary weight of digital signatures.
Signater maintains complete and immutable audit trails of the entire process, including timestamps, IPs, geolocation, and authentications, which can be presented as forensic evidence.
Yes, extremely safe! Signater uses state-of-the-art security technologies:
AES-256 encryption at rest and TLS 1.3 in transit, cloud infrastructure with ISO 27001, SOC 2, and GDPR certifications, multi-factor authentication, SHA-256 cryptographic hashes to ensure integrity, and immutable audit trails with optional blockchain.
Your documents are protected against fraud, tampering, and unauthorized access with bank-grade technology.
The vast majority of documents can be signed electronically in Brazil: commercial contracts, service agreements, proposals, acceptance terms, powers of attorney, declarations, employment contracts, HR documents, lease and purchase/sale agreements, NDAs, and many others.
Some legal exceptions include wills, prenuptial agreements, and certain acts that require notarized signatures by specific law.
We recommend consulting legal counsel for specific and critical cases.
Validity is verified through a robust cryptographic process. For signatures with ICP-Brasil certificates, verification validates the certificate's chain of trust, confirms it hasn't been revoked, verifies identity, and ensures the document hasn't been altered.
Signater provides independent verification tools and maintains complete records in audit trails.
Anyone can verify authenticity by accessing the public verification link or validating the digital certificate directly, ensuring full transparency.
