An electronic signature is an electronic sound, symbol, or process attached to, or logically associated with, an electronic record and adopted by a person with the intent to sign it.
Also called an e-signature, it is the electronic equivalent of showing approval, consent, or authorization with a handwritten signature. It can appear as a typed name, a signature drawn on a screen, an uploaded image of handwriting, or an action such as selecting an acceptance box.
The appearance of the mark is only one part of the definition. What matters is whether the signer intended the action to serve as a signature and whether that action can be connected to the relevant document or record.
What Can Count as an Electronic Signature?
Electronic signatures can take several forms:
- Typing a name into a signature field
- Drawing a signature with a mouse, touchscreen, or stylus
- Uploading an image of a handwritten signature
- Clicking a clearly labeled button such as “Accept and Sign”
- Selecting a checkbox that records agreement to identified terms
- Using a certificate-based signing method
- Providing an electronic sound or recorded confirmation in a context where it is intended and accepted as a signature
Context matters. A typed name at the bottom of an email may count if the sender placed it there to approve or authenticate the message. An automatically generated email footer containing the sender’s name may not show the same intent.
Similarly, clicking an ordinary navigation button is not an electronic signature. The action must be presented and recorded as an act of signing, approval, or acceptance.
The Role of Intent, Identity, and Document Association
A reliable electronic signing process connects three important elements:
- Intent: The signer takes a clear action showing that they mean to sign or accept the record.
- Identity: The process gathers evidence connecting that action to a particular person.
- Document association: The signature is attached to, embedded in, or logically linked with the exact record being signed.
A typical signing workflow may send a document to an identified email address, ask the recipient to review it, present a clear signing statement, record the signature action, and preserve the completed document.
The strength of the identity check can vary. Basic workflows may rely on access to an email account, while higher-risk transactions may use passwords, one-time codes, identity documents, or other forms of signer authentication.
Authentication does not replace intent. A person can prove who they are without agreeing to a document. The workflow must still make the signing action clear.
Electronic Signature, Digital Signature, and Wet Signature Compared
These terms are related, but they do not mean the same thing.
| Signature type | Meaning | Typical form | Main distinction |
|---|---|---|---|
| Electronic signature | A broad legal and practical concept for signing an electronic record | Typed name, drawn mark, uploaded image, or acceptance action | Focuses on the signer’s intent to sign electronically |
| Digital signature | A type of electronic signature that uses cryptographic technology | Certificate-based signature linked to cryptographic keys | Helps verify origin and detect document changes |
| Wet signature | A handwritten signature applied with ink to a physical document | Pen on paper | Exists in an original physical form |
Every digital signature is electronic, but not every electronic signature is digital. A typed name can be an electronic signature without using cryptography.
Scanning a paper document containing a wet signature creates an electronic copy of that signature. Depending on the context, the copy may be accepted as an electronic signature, but it is not the original wet-signed document.
Legal Effect Depends on More Than the Format
Electronic signatures are widely recognized, but they are not automatically valid or enforceable in every situation.
In the United States, the federal Electronic Signatures in Global and National Commerce Act, commonly called the E-SIGN Act, generally prevents a signature or contract from being denied legal effect solely because it is electronic. State electronic transaction laws, often based on the Uniform Electronic Transactions Act, provide a similar foundation.
This means electronic form alone is generally not a reason to reject a signature. It does not mean that every electronically signed agreement is enforceable. The underlying agreement must still satisfy applicable requirements concerning matters such as consent, capacity, authority, lawful purpose, required disclosures, and record retention.
Some documents and transactions may be excluded from general electronic signature rules or may require additional formalities. Wills, family-law documents, court filings, deeds, notarized records, and certain official notices are common areas where separate rules can apply.
The European Union uses a tiered framework under eIDAS, distinguishing electronic signatures, advanced electronic signatures, and qualified electronic signatures. Only qualified electronic signatures are expressly given the same legal effect as handwritten signatures throughout the EU. Other electronic signatures cannot be rejected as evidence solely because they are electronic, but their legal weight depends on the circumstances.

Evidence Behind an Electronic Signature
A signature image alone may show what appeared on a document, but it may reveal little about who placed it there or what they intended. Supporting evidence can make the signing event easier to verify.
An electronic signature audit trail may record:
- When the document was sent, viewed, and signed
- The signer’s email address or account
- Authentication events
- Consent and acceptance actions
- IP address or device information
- The version of the document presented
- Changes made before or after signing
- Completion and delivery events
Not every transaction requires the same evidence. A routine internal approval may need less assurance than a major financial agreement. The appropriate process depends on the value, sensitivity, dispute risk, and legal requirements of the transaction.
An audit trail also does not guarantee enforceability. It provides evidence about the process, while a court or other authority determines how much weight that evidence carries.
Where Businesses Use Electronic Signatures
Businesses commonly use electronic signatures for sales agreements, proposals, nondisclosure agreements, vendor forms, employment documents, policy acknowledgments, and internal approvals.
They reduce dependence on printing, mailing, scanning, and manually tracking signature pages. They can also keep the document, signer actions, and completion record together in one workflow.
However, an electronic signature does not verify that every statement in a document is true, give someone authority they do not have, or remove witnessing and notarization requirements. Organizations should match the signing method to the document rather than treating every signature request as identical.
FAQ
Is a typed name an electronic signature?
It can be. A typed name may qualify when the person enters it with the intent to sign and it is associated with the relevant electronic record. A name inserted automatically without a signing action may not show sufficient intent.
Is an electronic signature the same as a digital signature?
No. Electronic signature is the broader category. A digital signature is a specific type that uses cryptographic methods to help authenticate the signer and detect changes to the document.
Can an electronic signature be legally binding?
Yes, an electronic signature can be legally binding, but electronic format alone does not make an agreement enforceable. The transaction must meet the applicable legal requirements for the document and jurisdiction.
Can someone copy an electronic signature image?
Yes. A visible signature image can be copied, just like a handwritten signature can be imitated. Authentication, document integrity controls, and audit records provide stronger evidence than the image alone.
Do I need special software to create an electronic signature?
Not always. A person can type or insert a signature into a document using common software, as explained in how to insert an electronic signature in Word. Dedicated signing tools are more useful when a business needs authentication, multiple signers, status tracking, document controls, or an audit trail.
