Signature Forgery Explained - Types, Risks, and Protection Tips

Signature forgery is the act of imitating or replicating a person’s signature without their authorization—whether on paper or digitally—to carry out illegal activities such as fraud or identity theft. Forgers use various methods to deceive others into believing the forged signature is genuine.

Signature forgery is a serious crime and can have heavy punishments like imprisonment and hefty fines, which in some cases, could go up to millions of dollars.

Forgery can harm victims not only financially, but also by damaging their reputation. That’s why it’s important for every professional to be aware of this illigal act, how to prevent and detect it before it gets out of hand.

3 Types of Signature Forgery

Signature forgeries can be in different shapes and formats, but they can be grouped into one of the following three categories:

1. Simple Forgery

Simple signature forgery is when someone signs freehand other people’s names they have no authority to use.

💡 Good to Know: Signing on behalf of someone, when properly authorized (such as through a power of attorney or written consent), is different and legal in many cases.

2. Handwritten (Simulation) Forgery

• Simulated Signature: When the forger imitates the handwritten signature (wet signature) of someone by practice to replicate the exact genuine signature.
• Tracing Signature forgery: When the signature is forged by placing the original signature under a thin blank sheet and tracing it to create a duplicate, making it appear authentic.

3. Digital Forgery

Forging a digital signature can be more complicated and comes in many different shapes including:

• Copy-paste forgery: Forgers use image editing software to copy the signature and paste it where they want to create an exact duplicate.
• Signature forgery software: Some apps allow forgers to create fake signatures by either tracing an original or digitally replicating it. They often have features like adjusting stroke pressure, speed, and style to mimic the nuances of the original signature. They can even trace the real copy using image recognition tech and replicate a person’s signature from a scanned document or photo.
• Autopen machines: These machines can duplicate both traditional wet signatures and electronic ones by replicating the signature’s shape, pressure, and style.

How to Detect a Signature Forgery?

But how to tell if a signature is forged? Especially if it’s forged electronically, when there seems to be no trace, at least in the appearance.

The definite evidence that proves a signature has been forged is called “The Smoking Gun.” The smoking gun is different from case to case and the type of method used, but here are the common ways you can use to find the smoking gun:

Handwritten Analysis (Graphology)

Almost like fingerprints, each person’s handwriting is unique. By analyzing the style, pressure, flow, and strokes of letters in the signature, you can spot inconsistencies. This is exactly how graphologists find unnatural variations when studying a forged signature.

Some of these inconsistencies are:

• Shaky handwriting
• Letter proportions
• Pen lifts
• Pen pressure
• Stroke order and rhythm
• Signs of retouching

Signature Comparison

Comparing the suspected forged signature with several known genuine signatures can lead to spot differences in letter shapes, size, slant, and overall style. The comparison is usually made by putting the two images over each other in a closed box to find out the inconsistencies.

Pressure Patterns

Even if two signatures look exactly alike, a pressure pattern analysis can reveal a fake signature. Some signing characteristics such as muscle memory, pressure, speed, and stroke patterns is reveal a forgery.

Computer Analysis

Used mainly by law enforcement and banks, computer analysis is a sophisticated method of detecting a forgery. It’s a faster and more accurate method compared to the ones mentioned above since it spots irregularities that human eyes might miss.

In this method, the software uses a series of genuine signatures as a reference to analyze the possible forged signatures in question.

Digital Signature Verification

If the document is signed electronically but without taking security measures, forgers can find some cracks. Digital signature verification is a reliable way to spot forgery in electronic documents. Each digital signature is protected by encryption and tied to the signer’s unique identity, making it difficult to change without detection. For example, software can check the siners’ authenticity using encrypted keys, timestamps, and metadata to detect any tampering attempt.

What Are the Common Consequences of Signature Forgery?

Signature forgery can have serious consequences, not only for the forger but also for the victim.

Financial loss

Perhaps the most common result of signature forgery is financial loss. Unauthorized transactions or altered contracts using fake signatures can cause businesses to lose money directly.

The problem is, the financial loss does not end here. Investigating the forgery, let alone taking legal actions that could take months or even years, can further drain the business’ resources.

Legal Disputes and Lawsuits

Businesses can face serious legal issues when it’s proved that the signatures in their contracts and financial agreements have been forged.

They not only have to fight to recover their financial losses, but also they have to defend against the claims. In some serious cases, these lawsuits might even put a hold on their financial transaction.

Identity Theft

Although they’re two different things, signature forgery and identity theft normally go hand-in-hand. The forger can use the signature to open bank accounts, commit a crime, or sign contracts using the victim’s name.

Reputational Damage

Between 2002 and 2016, Wells Fargo’s employees forged millions of customers’ signatures by copying and pasting them onto new documents to open unauthorized accounts. 190,000 customers were unwittingly charged fees and as a consequence, the bank received more than $3 Billion in punishment fees.

Aside from the financial damage, this scandal damaged Wells Fargo’s reputation beyond repair, which had previously been built on a foundation of customer trust.

💡 Good to Know: Forgery is not just a criminal offense—it can also lead to civil lawsuits. Victims of forgery may pursue damages in civil court, including compensation for financial losses and reputational harm.

What’s the Penalty for Signature Forgery?

The punishment for signature forgery can vary from country to country and in different jurisdictions. But in most cases, forging a signature is classified as a felony or misdemeanor and can have serious penalties, including:

• Fines: From a few thousand to much higher, based on the forgery’s damage.
• Imprisonment: Ranges from months to years, especially for large-scale fraud.
• Probation: Some offenders may avoid jail but face conditions under probation.
• Compensation: Forgers may need to repay victims for their losses.
• Damages: Victims can seek additional damages in civil court for significant financial harm.

Best Practices to Prevent Signature Forgery

1. Sign Documents Digitally

If done through software, electronic signatures are the safest way to sign a document. They are encrypted, which means they’re far more secure than traditional handwritten ones.

Also, they leave behind an audit trail, including signer ID and timestamps so you can see exactly who signed the documents and when.

• Limited user access: you can modify which members of your team can make changes and modify your sensitive data.

3. Train Your Employees

Your employees are your first line of defense, so make sure they’re aware of the risks and know what to look for.

Regularly train them on how to handle sensitive documents and spot potential signs of forgery. A well-informed team can prevent a lot of problems before they happen, so don’t underestimate the power of good training.

You can use a mix of workshops, online courses, and regular team meetings to make sure that everybody is well-informed.

Also, it’s always a good idea to have a risk management plan in case any forgery happens. It helps you to respond quickly and effectively, minimize the damage, and outline the steps for investigating and resolving the issue.

What Should You Do If Someone Forges Your Signature?

1. Verify the Forgery

Double-check the document and make sure the signature is actually forged. Compare it to your authentic signatures to spot any differences.

2. Gather Evidence

Keep a copy of the forged document and collect any supporting materials, like emails or contracts, that prove the forgery.

3. Notify the Affected Parties

Inform anyone involved with the document, such as business partners or clients, about the forgery to prevent further damage.

4. File a Police Report

Report the forgery to local authorities to have an official record, which can be important for future legal action.

5. Consult a Lawyer

Speak with a lawyer to understand your legal options and get advice on how to move forward, especially if you plan to take legal action.

💡 Good to Know: Many legal systems place the burden of proof on the victim when it comes to forgery cases. It’s crucial to gather strong evidence and work with legal professionals to build a solid case.

6. Notify Financial Institutions

If the forgery affects your bank accounts or financial matters, immediately notify your bank to stop any unauthorized transactions.

7. Dispute the Document Legally

Work with your lawyer to challenge the validity of the forged document in court or through proper legal channels.

8. Strengthen Future Security

Review your security practices, such as using digital signatures or limiting document access, to prevent future forgery incidents.

Signature Forgery VS Identity Theft: What are the Differences?

The main difference between the two is scope. Signature forgery is typically limited to falsifying a single signature on a document, whereas identity theft involves taking over the entire identity of a person.

Signature forgery often leads to specific fraudulent actions, like altering contracts, while identity theft is used for broader, more widespread fraudulent activities, including financial crimes and impersonation across various platforms.
