Are E-Signatures Legally Binding in 2025? Complete Legal Guide

Are Electronic Signatures Legally Binding? What Actually Holds Up in Court

You send a contract to a client in Singapore. They add their digital signature. It’s back in your inbox within minutes.

Done, right? Maybe.

If you’ve ever wondered, “Is this signature actually binding?”—good. You should be asking that question.

Even though electronic signatures carry legal weight in most cases in the U.S. and globally, you need to know what makes a signature valid in court.

What Makes an Electronic Signature Legally Valid?

An electronic signature is legally binding when it meets several requirements:

• Intent to sign. The signer has to clearly intend to adopt the signature. This can be by typing, drawing, clicking “I agree,” but they need to intend to sign.
• Consent to use electronic signatures. All parties agree to do the transaction electronically.
• Association with the document. The signature gets attached to or logically associated with the electronic record.
• Retention and reproducibility. The document and audit log are stored securely and reproducible on demand.

Of course, the document type must also accept digital signatures instead of ink ones. Most legal documents are just fine with digital signatures, but there are a few exceptions that we’ll talk about a bit later in this post.

Laws Governing Electronic Signatures in the U.S.

Two federal statutes give electronic signatures legal status:

• ESIGN Act (2000). No signature can be denied legal effect just because it’s electronic.
• UETA (Uniform Electronic Transactions Act). Adopted by 49 states plus D.C. and the Virgin Islands. Sets a consistent legal foundation for electronic signatures and records. Each state has its own variations, so check your state-specific information. In case you’re curious, at the time of writing this article, New York was the lone holdout. They have their own Electronic Signatures and Records Act that has similar provisions.

Together, these Acts establish that electronic signatures are legally recognized and have the same legal force as handwritten signatures.

Global Legal Framework for Electronic Signatures

Legal digital signatures aren’t just happening in the U.S. Most regions now regulate and accept electronic signatures legally:

International legality matters if your contracts operate across borders.

Electronic Signatures in Court

Are electronic signatures admissible in court? Yes. If you can prove who signed what and when.

To be admissible in court, an electronic signature needs authentication (IP address, device, signer ID). Document integrity—the file is tamper-evident and hasn’t been altered. Audit log where every open, view, and sign event is logged. Reproducibility, so you can generate and show the signed document later, with metadata intact.

Without these? You risk the signature being denied legal effect.

Common E-Signature Exceptions

Not every document can be signed digitally. Most U.S. and global laws exclude certain categories.

A wet signature is usually required for: Some wills and trusts; however, certain states are beginning to change their stance on wills to include e-wills. Adoption documents. Divorce filings. Court pleadings. Some real estate contracts (varies by state). Marriage licenses.

Why? These involve specific legal requirements: notarization, in-person witnessing, or statutory forms.

Security Features That Prove Legal Validity

The best electronic signature solutions don’t just collect clicks. They preserve evidence.

Here’s what matters:

Digital certificates verify signer identity and authenticate timestamps. Tamper-evident technology flags any post-signing alterations. Encryption locks both the document and the metadata from unauthorized access. Multi-factor authentication verifies signers before signing. Secure audit log tracks everything, from view to signature.

Platforms like Signus are built with this at the core.

Legal Checklist 

Want to check compliance? Here are a few things to consider.

• [ ]The signer intended to sign.
• [ ]All parties consented to the electronic transaction.
• [ ]The signature is logically associated with the document.
• [ ]You can reproduce the signed record and audit log.
• [ ]The platform you used supports authentication, integrity, and retention.
• [ ]The document type is eligible for electronic execution under law.

Meeting these criteria means your electronic signature is likely legally enforceable in any jurisdiction that honors digital contracts.

Best Practices for All Types of Documents

Do: Use trusted e-signature platforms with audit logs. Authenticate signers with verified emails or 2FA. Store signed agreements with full metadata, forever. Check local and international electronic signature laws. Present terms clearly.

Don’t: Rely on a signature image pasted into a PDF. Skip consent for electronic transactions. Assume all documents are eligible. Lose, or worse, don’t create the audit log.
