Much has been written on electronic signatures. In this article, we would like to present a simple guide on e-signatures and what makes them legally binding.

In the modern world, everything has digitalized with time. From online shopping to automation of complex business functions, everything is digital today, and it lays the foundation of our future as well. One of the things that has become popular is electronic signatures or e-signatures.

However, because it appears to be easy to sign a document online, many are often concerned about the legality of e-signatures. Does the e-signature on a legal agreement give the document any legal status?

What is an e-signature?

The first thing you have to know is what an e-signature is. Just like your inked signature, signing documents online is a way for you to sign documents, except that e-signatures are multi-dimensional. There are many ways for you to do it.

You could use an e-signing tool that gives you the ability to sign a document with a mouse click or draw your signature on a digital document using a mouse. The presence of such a signature on a document may or may not give it a (stronger or weaker) legal status, depending on various factors that you will read later in the guide.

The legality of electronic signatures.

Now that you know what e-signatures are, you must be wondering about their legality. Yes, you could put an electronic signature on a document but does doing so make the document legal?

Electronic signatures are legally binding in thirty European countries, the United States and the vast majority of countries around the world. An electronic signature can carry the same weight and legal effect as a traditional paper document with a pen and ink signature.

In all the countries where e-signatures are legally binding, its legal status depends on proving the presence of these three elements:

#1 WHO: Who has signed?

This is the part where the identity of the signatory must be verifiable. There are a number of methods that can be used to perform identity verification such as using verification via SMS, email, electronic ID, for example, BankID in Sweden. The stricter the identity control there is in the method, the higher the security the method offers.

On top of this, a lot of information about every request made to the document or contract are saved and logged. It is important to remember that none of these identification method is 100% secure, even though digital is almost always better than the analog alternative!

#2 WHAT AND INTENT: What was signed?

The next part that affects the legal status of a signed document is the content of the document and the intent of the parties. What was signed? Did the parties invite to the contract intend to sign and legally commit to the document?

This is where the contract content and what the parties stated in the signed version of the document matter. If a contract changes before being signed, then the new wording becomes a new contract offer. If there is more than one party invited to sign the document, then the contract is only signed when all have signed, thus agreeing on the common content.

#3 INTEGRITY: Has the document been changed or tampered with after signing?

The final part that is important to determine the legal status of an electronically signed document is the integrity of the document after signing. This means that after the parties have signed the document, it must be kept intact and not be modified or tampered with. By using an electronic signature based on PKI, the document gets hashed and signed using an asymmetric encryption key pair.

The integrity of the document is thereby protected so that even a slight change in the document, e.g. change of a comma, a point or space, would create a different hash value, thereby revealing that a change has occurred.

Qualifications for an e-signature to be legally binding.

As you can tell by now, not every electronic signature will be found to be legally binding. Obviously, you cannot just take a picture of your signature on a piece of paper, crop it, and paste in your documents to use it for making the documents “legal”; this method will not provide any decent level of evidence as someone else can easily copy-paste it from your document to another document.

The legal value of an electronic signature will depend on its ability to prove who applied it, the identity of that person and that the signed data has not changed after signing.

Regulation of electronic signatures.

The types of signatures described above are described in more detail in the eIDAS (electronic IDentification, Authentication and trust Services) Regulation of the European Union. eIDAS is a comprehensive regulation dealing with electronic identification and trust services for electronic transactions in the European Single Market. In the US the ESIGN Act is regulating e-signatures on the federal level.

Oneflow follows the standards and best practices set out in or following from the eIDAS regulation.

Types of electronic signatures.

There are different types or levels of electronic signatures according to the eIDAS Regulation: SES (Simple Electronic Signature), AdEs (Advanced Electronic Signature), and QES (Qualified Electronic Signature).

SES (Simple Electronic Signature)

The definition of an Electronic Signature under Swedish and EU law means that “means data in electronic form which is attached to or logically associated with other data in electronic form and which is used by the signatory to sign” (eIDAS Regulaton article 3). As there are no specific security requirements laid down by law, it is not possible to determine the legal value of such signature without evaluating the method and security applied in the specific case.

AdES (Advanced Electronic Signature)

As the name suggests, it is an advanced form of signature that offers more security than a simple electronic signature and can also identify the person who has signed the document. This type of e-signature allows you to detect if someone has tampered with the signature after the signatory has put it on the document. These signatures are made secure with the help of cryptographic keys. According to eIDAS Regulation, an advanced electronic signature means “an electronic signature which meets the following requirements:

  1. it is uniquely linked to the signatory;
  2. it is capable of identifying the signatory;
  3. it is created using electronic signature creation data that the signatory can, with a high level of confidence, use under his sole control; and
  4. it is linked to the data signed therewith in such a way that any subsequent change in the data is detectable.”

QES (Qualified Electronic Signature)

The eIDAS Regulation defines qualified electronic signature as “‘qualified electronic signature’ means an advanced electronic signature that is created by a qualified electronic signature creation device, and which is based on a qualified certificate for electronic signatures”.

These signatures are advanced e-signatures but must adhere to certain EU standards (i.a. based on a so called qualified certificate), which means they offer additional protection controls over the advanced counterparts. You create this signature with the help of a device that’s specifically designed to create e-signatures. A court must normally admit these certificates the same legal value as a handwritten signature.

Using a qualified seal with an electronic signature.

Contract verification in Oneflow - your proof that e-contract is signed legally.

Once a contract in Oneflow has been signed in Oneflow’s e-contracting process by all signatories, Oneflow adds additional security and validity information to the contract bundle, after which the whole bundle is sealed with a Qualified Electronic Seal.

As with electronic signatures, electronic seals also have different types according to the eIDAS Regulation: Simple, Advanced and Qualified. The principle is similar to that of the electronic signature level – the requirements of each level of the electronic seal build on the requirements of the level below it. A Qualified Electronic Seal meets the most requirements and a Simple Electronic Seal the least.

The seal is there to prevent both intentional and accidental change the document after it was signed, meaning you and your counterparties can remain secure in the knowledge that what you signed today will remain verifiably unchanged now and in the future, even if that is 20 years away.

The seal used by Oneflow is applied by its partner Sovos TrustWeaver.

how to check e-signature qualified
  • Option A: Your document does not have a sign on it even though the signatories have been identified by your e-sign service.
  • Option B: The document is verified with the signature and the signatories too. However, signature verification will be difficult without your e-sign service.
  • Option C: This is the best option that verifies your signature as qualified e-signature. That’s the most secure form of e-signature you can have today.

The key benefits of using electronic signatures.

It saves you time.

Imagine a scenario where you have to negotiate an agreement with a company located in a country on the other side of the world. The entire printing, signing, posting, etc. process will take days if not weeks. Once the recipient receives the documents, they will repeat the same process of printing the document, signing it, and posting it to you. This back and forth process is going to take a lot of time. On the other hand, you can close a deal within minutes using e-signatures.

It lets you sign on the go.

The modern world loves the idea of on-the-go. You should be able to do things while you are on the move. From shopping online to trading, you can do it all on your mobile phones today. E-signatures let you do the same i.e. you can sign the document regardless of where you are.

It saves you money.

Time is money, and with e-signatures, you can save a lot of it. In addition to that, think of all the paper that you have to waste to put lengthy agreements on. Unsurprisingly, some agreements can be tens of pages. That’s a lot of waste of paper and natural resources. With e-signatures, you can go paperless entirely.
