After all, what is the crime for forging a signature?

O crime of signature forgery It's not just ethically reprehensible behavior; it's a criminal offense that can have serious legal, financial, and reputational consequences for individuals and businesses. After all, nowadays, document authenticity plays a central role in the security of operations, especially in the financial, legal, and commercial sectors.

Therefore, in companies, combating signature forgery is also a way to avoid litigation and ensure the reliability of business relationships. Preventing this crime is directly linked to adherence to electronic signature, which offers robust traceability, encryption and authentication mechanisms.

Data misuse can lead to operational losses, legal challenges, and damage to the company's image. This reinforces the importance of auditable digital processes that ensure not only document validity but also transparency at all stages of corporate negotiations.

In this article, we show how signature forgery should be treated not only as a one-off threat, but as a systemic risk that can compromise an organization's entire governance structure.

Penalties and impacts of signature forgery

The consequences of signature forgery extend beyond the criminal sphere. Companies involved in such cases may face civil lawsuits, financial losses, and reputational damage. Furthermore, forged signatures on employment documents or service contracts can lead to legal action with regulatory agencies and may result in compensation claims.

In civil cases, victims are entitled to compensation for material and moral damages. The Civil Code provides for the annulment of falsified documents and the restoration of the conditions prior to the unlawful act.

Cases involving digital contracts have increased in recent years, and case law now recognizes the validity of digital signatures in legal disputes. Therefore, forging an electronic signature can be as serious as forging a handwritten signature, especially if the document is signed by digital certificate means.

How to identify a fake signature?

Detecting a forged signature is a crucial step in starting any investigation. Visual, technical, and digital methods combine to make identification safer and more effective. Technical knowledge, combined with technology, allows legal professionals to identify fraud before it causes more serious damage.

A good practice is to maintain a document history with authentic signatures from employees, customers, and suppliers. This facilitates immediate comparison in case of suspicion. Furthermore, companies that use platforms with validation of digital signatures have an additional layer of protection against tampering.

The analysis should always consider the context: location of the signature, method used (paper or digital), type of document, and the behavior of the parties involved. In digital environments, technology can identify changes in the file's content or the lack of tracking in the acceptance process.

Let's now look at the details of each identification method.

Visual comparison

In the case of handwritten signatures, close observation allows for the identification of inconsistencies. Shaky lines, irregular spacing, differences in pen pressure, and letter formation errors are common signs of forgery.

Comparing the suspect signature to known samples is the first step. It's also worth considering the person's natural signing behavior: speed, fluidity, and spontaneity are difficult to imitate. Digital signature collection platforms electronic documents may include action logs, which indicate the time and place where the signature was made, strengthening the validity of the document.

Graphotechnical examination

When visual analysis isn't enough, a graphotechnical examination comes into play. Performed by specialized experts, this type of evaluation uses resources such as a microscope, ultraviolet light, spectrophotometry, and line pressure analysis.

The report produced by the handwriting expert is accepted in court and can support criminal or civil proceedings. Often, the mere suspicion of tampering is sufficient to justify hiring an expert. It's recommended that the company has a trusted partner for this type of service or be prepared to call in forensic consulting whenever necessary.

Digital verification tools

In electronic documents, it is possible to use verification tools to identify whether a digital signature has been tampered with or whether the file's content has been altered after acceptance. These features also indicate the legal validity of the signature.

Besides validators, many platforms provide complete records of the signing process, such as the signer's IP address, date, time, and document hash. These records serve as solid evidence in potential litigation and are compliant with technical standards such as ICP-Brazil and ISO 27001.

What to do when you detect a signature forgery

If fraud is suspected, the first step is to immediately suspend use of the document until its authenticity is verified. From there, a containment and investigation process involving different areas of the company is necessary.

1. Investigate what happened: collect original documents and previous signatures.
2. Contact the legal department: to define appropriate measures and possible notifications to third parties.
3. File a police report: formalizing the suspicion with the authorities.
4. Communicate with customers and partners: when there is external impact.
5. Refine internal security policies: mainly in relation to document management.

If the signature is on a digital document, it is also recommended to use signature platforms with a complete authentication history, ensuring greater control over the processes and security in the event of an audit or legal dispute.
