The process of digital signature on digital certificate at notary office This involves issuing an electronic identity used to authenticate acts with greater security, legal validity, and less bureaucracy. This can be done through notary offices, e-Notary services, and also through ICP-Brasil certificates issued by accredited Certification Authorities, depending on the type of use required in your workflow.
When a company needs to formalize documents quickly, the issue ceases to be merely technical and becomes operational. Understanding how to obtain a digital certificate at a notary's office helps reduce queues, avoid rework in registration, organize renewal deadlines, and choose the right path between in-person validation, video conferencing, and subsequent use in contracts, powers of attorney, and other electronic documents.
Summary
- The certificate issued in a notary context and the ICP-Brasil certificate do not have exactly the same scope of use.
- The process typically involves choosing an issuer, registration, document submission, identity verification, issuance, and secure storage.
- Simple errors, such as a mismatched name or incorrect email address, can delay completion and increase rework.
- Issuance time, completion rate, and volume of corrections are useful KPIs for monitoring process efficiency.
Quick facts
- O VALIDATE service It is an official reference for verifying the integrity and authorship of electronic signatures recognized by the government.
- O e-Notary It was identified by the CNJ (National Council of Justice) as a platform already well-established in the practice of online transactions.
- A electronic signature gov.br Requires a silver or gold account for use in official service.
Before going through the step-by-step process, it's worth distinguishing between two concepts that are often confused. The ICP-Brasil certificate is a digital identity with broad use in different services and systems. The notarized digital certificate, on the other hand, is linked to the environment of electronic notarial acts and e-Notariado, which changes the practical scope of the credential and the type of document it supports.
What is a notary digital certificate?
When someone talks about digital certificate notaryThis typically refers to obtaining credentials used for electronic acts involving the notarial environment. Operationally, this may involve an ICP-Brasil certificate issued by an accredited CA or a notarized certificate geared towards the notarial ecosystem. The correct choice depends on the holder's objective, the document, and the system where the signature will be used.
From a legal and technical standpoint, the most reliable basis for understanding is that a digital certificate serves to link the holder's identity to a pair of cryptographic keys, allowing for authentication and signature with verifiable integrity. In the context of notary services, this benefit is coupled with the electronic formalization of acts, the reduction of travel, and the organization of document flow in a digital environment.
Difference between an ICP-Brasil certificate and a notarized certificate.
ICP-Brasil is more comprehensive. It may be required for tax integrations, business obligations, petitioning, qualified signatures, and other environments that depend on the official certification chain. A notarized certificate, on the other hand, is usually associated with use in electronic notarial acts within e-Notariado, which solves a specific set of notarial needs, but does not replace all corporate scenarios.
| Criterion | ICP-Brazil | Notarized |
|---|---|---|
| Scope of use | Broad, including outside the registry office. | Focused on electronic notarial acts. |
| Emitter | Accredited Certification Authority | Environment linked to e-Notary/registry office |
| Typical application | Qualified signature, digital obligations and various systems | Electronic notarization and notarial acts |
| Ideal evaluation | When a company needs recurring and broader usage. | When the focus is on the electronic notarial act. |
In the official ITI material, the definition of the ICP-Brasil certificate is linked to the identification of the holder within the chain of trust and the use of cryptographic keys; at the same time, the CNJ Provision No. 100/2020 It has historically organized the practice of electronic notarial acts within the e-Notariado system, which helps to understand why the topic has come to be addressed in a more integrated way in the digital environment.
How to obtain a digital certificate at a notary office in 7 steps.
The process tends to become simpler when the company standardizes the phases. Instead of treating each issuance as an isolated case, it's worthwhile to establish a workflow with clear checkpoints, defined responsibilities, and a pre-established list of documents. This reduces corrections, speeds up service, and improves the experience for those who need to complete the issuance to sign contracts or perform formal acts.
1. Define the intended use before choosing the emitter.
The first step is to decide whether the holder needs a credential focused solely on the notary ecosystem or a certificate with broader use. If the demand involves qualified signatures, business systems, tax authorities, e-CAC (Brazilian Federal Taxpayer Service Center), or recurring legal routines, the assessment usually points to alternatives such as... digital certificate, e-CNPJ or cloud-based issuance according to the user's profile.
2. Choose the registry office or Certification Authority based on objective criteria.
At this stage, compare scheduling availability, validation methods, issuance deadlines, support, service channels, and cost transparency. In business operations, the best supplier isn't always the cheapest on the label. Ideally, you should measure the total cost of the process, including travel, team time, waiting times, document resubmission, and the impact on the final document signature.
Practical selection criteria:
- Average time for validation and issuance;
- In-person, remote, or hybrid service;
- clarity regarding required documents;
- Compatibility with cloud-based certificates, A1 or other formats;
- Easy renewal and post-issuance support.
In 2021, ITI (National Institute of Information Technology) announced that issuing ICP-Brasil certificates via videoconference had become standard practice, focusing on simplification, speed, and cost reduction. Therefore, this format should be considered when the company's internal policy allows it, as shown in the announcement from [the relevant authority/organization]. ITI on videoconferencing.
3. Complete the registration with a genuine review of your registration information.
After the selection process comes the registration. This is where many avoidable delays arise. Legal name, CPF (Brazilian individual taxpayer registration number), CNPJ (Brazilian company taxpayer registration number), email, phone number, and representation documents must be consistent with official records. In companies, discrepancies between the articles of incorporation, power of attorney, and representative documents generate unnecessary pauses. A good practice is to review everything before submission, using a checklist validated by the legal or administrative department.
If the goal is to sign business documents with less friction, this step deserves the same attention given to... document managementCorrecting registration information after validation usually takes more time than reviewing data at the beginning.
4. Submit the required documentation
The required documents vary depending on the type of certificate and the holder's profile. Individuals, legal representatives, managing partners, and attorneys-in-fact are not included in the same process. Ideally, identification, supporting documents, corporate documents, and any acts of representation should be separated into a standardized folder, preferably with legible, up-to-date files in a format accepted by the issuer.
| Type of holder | Documents typically reviewed | Most common risk |
|---|---|---|
| Physical person | Official document, CPF (Brazilian taxpayer ID), registration details | Illegible image or conflicting data. |
| Company representative | Personal document, CNPJ (Brazilian tax ID), corporate act. | Outdated power of representation |
| Attorney | Power of attorney, identification and company documents. | Insufficient or expired power of attorney |
5. Complete the in-person or video conference validation process.
This is the point at which the identity of the holder is confirmed. Depending on the solution chosen, the verification occurs in person or via video. In a notarial setting, videoconferencing has gained prominence with the digitization of acts. In ICP-Brasil certification, the remote modality has also become part of the process according to ITI regulations, which shortens steps and can reduce operational costs.
For more robust digital workflows, this moment aligns with best practices. digital document authentication, identity validation and even with complementary methods such Biometry, when the operation requires more security.
6. Issue, install, and test before first use.
After approval, the certificado digital é emitido. A partir daí, não basta guardar o arquivo ou liberar o acesso. É recomendável fazer um teste controlado, verificando se o certificado foi instalado corretamente, se a senha está sob guarda adequada e se o titular consegue utilizá-lo no fluxo previsto. Em contexto corporativo, esse teste evita falhas na hora de assinar o documento real.
It is also helpful to align usage with the platform where the documents will be signed. In recurring processes, understanding how to sign document with digital certificate and how it works signature with digital certificate It reduces uncertainty at the point of contact.
7. Establish a routine for storing, renewing, and monitoring the vehicle.
The certificate has an expiration date and requires governance. This includes securely storing credentials, defining who is responsible for renewal, recording expirations, and monitoring usage incidents. In legal and commercial teams, an expired certificate mid-process stalls signing, affects SLAs, and can push operations back to paper-based processes.
Best practices, costs, and KPIs of the process.
The benefit of the process lies not only in the issuance of invoices, but also in predictability. When the team monitors indicators, it becomes easier to know if the current model truly saves time and reduces costs. This is where the topic connects with... process optimization and with a useful measurement routine for legal, sales and back office.
- Issue time: time interval between request and active certificate.
- Completion Rate: Percentage of requests completed without abandonment.
- Rework: Number of cases involving registration corrections or document resubmission.
- Cost per issue: sum of fees, travel expenses, staff hours, and support.
- Time until first subscription: It measures when the certificate starts generating real value.
Regarding prices, the market varies according to the type of certificate, validity period, storage method, and issuer policy. In the notary environment, there may also be fees or charges related to the notarial act itself, not just the issuance of the credential. Therefore, comparing proposals without considering the scope and end use usually produces a distorted calculation.

Frequently Asked Questions (FAQ)
Are a digital certificate issued by a notary public and an ICP-Brasil certificate the same thing?
Not necessarily. In everyday use, many people treat the two as equivalent, but the scope may change. ICP-Brasil has a broader use in different systems and services. Notarized certificates, on the other hand, are usually linked to the environment of electronic notarial acts. Before issuing, it's worth confirming where the document will be signed and which standard is accepted.
Is it possible to conduct the validation process via video conference?
Yes, in many cases this is already part of the process. Availability depends on the type of certificate, the issuer's rules, and the documentation submitted. For the company, videoconferencing usually reduces travel and facilitates scheduling. Even so, the certificate holder must comply with the identification, image quality, and document verification requirements defined by the process.
What errors cause the biggest delays in issuing the invoice?
The most common delays arise from discrepancies in registration information, illegible documents, incorrect email addresses, outdated articles of incorporation, and inadequate power of attorney for representation. In business operations, another frequent error is initiating issuance without first deciding on the scope of use. This leads to choosing a type of certificate that does not meet the system's or the final document's requirements.
How long does it take to complete the process?
The timeframe varies depending on the issuer, the type of validation, and the quality of the registration. When the data arrives correctly and the schedule is available, completion tends to be faster. However, discrepancies in documentation and the need for corrections increase the total time. Therefore, monitoring average timeframes and rework helps to measure efficiency and anticipate bottlenecks.
How can I tell if a signature made with a certificate is still valid?
The safest way is to validate the electronic document with the appropriate service and preserve the original file, without unnecessary conversions. Digitally signed documents should remain in electronic format to maintain complete verification of integrity and authorship. It is also recommended to keep a record of issuance, certificate expiration, and evidence of the signature performed.
