What Is a Wet Signature and When Do You Need One?

Have you ever found yourself wondering why you still have to physically sign important documents with a pen, even when everything else can be done electronically? Welcome to the world of the wet signature—the classic handwritten signature using ink on paper. Despite the convenience of electronic signatures, wet signatures remain a requirement for certain legal documents, especially in more traditional or regulated industries.

If you're about to finalize something significant like purchasing a home, signing a will, or closing on a contract in places like California, North Carolina, or Illinois, you may still need to pick up a pen. In this guide, we’ll explain what wet signatures are, why they’re still used, and when you need one, despite the rise of digital alternatives like eSignatures.

What Exactly Is a Wet Signature?

A wet signature is a handwritten signature made with ink on a physical document. It's the traditional method we've relied on for centuries to signify agreement or approval on important paperwork.

Why Are Wet Signatures Still Used?

While digital alternatives are becoming more common, wet signatures are still required in many circumstances, such as:

• Contracts: Large purchase contracts, such as those for a house or car, may still need a handwritten signature, though the number of industries relying on wet signatures is rapidly declining.
• Official Forms: Government agencies often require wet signatures on tax forms, licenses, passport applications, and other official documents.
• Legal Documents: Certain legal documents like wills, trusts, and powers of attorney may still require wet signatures to be considered legally valid, depending on the state.
• Checks: Personal checks need to be signed by hand to authorize the transaction.

Are Wet Signatures Becoming Obsolete?

Yes and no. While eSignatures are now legally valid for most documents, and many sectors have adopted them, certain legal and governmental documents still rely on wet signatures for perceived authenticity and security. That said, technology is moving fast, and services like BlueNotary are making Remote Online Notarization (RON) more common and secure. Wet signatures won’t vanish tomorrow, but they’re gradually becoming less necessary.

When Is a Wet Signature Required?

1. Legal Documents

For legal documents like wills and affidavits, some states still require a wet signature. However, many states are starting to adopt online notarization, where digital signatures are legally recognized as equivalent to wet signatures.

2. International Contracts

For contracts involving parties from different countries, wet signatures are often required due to varying eSignature laws. Countries have differing rules on the validity of digital signatures, so a handwritten signature on paper may be necessary to avoid legal issues.

3. Sensitive Agreements

High-stakes agreements—like those involving large sums of money or valuable assets—may require wet signatures to prevent disputes. For example, some financial institutions still prefer or require wet signatures for certain loan agreements.

4. Original Copies

In some situations, such as legal disputes, original wet signatures are required. Courts may ask for the original copy with a wet signature to verify the authenticity of the document. This is especially true for deeds and property transactions.

eSignatures vs. Wet Signatures: Pros and Cons

eSignatures

Pros:

• Convenience: Sign from anywhere without needing to print, sign, and scan documents.
• Speed: Almost instant; no need to wait for postal delivery.
• Security: Many eSignature platforms like BlueNotary use encryption and biometrics, making it hard to tamper with or forge.
• Legally binding: Recognized in most countries under laws like the U.S. ESIGN Act.

Cons:

• Not universally accepted: Some traditional organizations or international contracts may still require a wet signature.
• Security concerns: There’s potential for cybersecurity threats if not using a trusted service provider.

Wet Signatures

Pros:

• Widely accepted: Universally recognized and accepted for almost all legal transactions.
• Tangible proof: Original signed copies can be physically examined for authenticity.

Cons:

• Inconvenience: Requires physical presence or mailing documents, which can delay processes.
• Storage: Physical documents can be easily lost or damaged.
• Environmental impact: Requires paper, printing, and shipping, which isn’t eco-friendly.

Wet Signature Conclusions

While wet signatures are still required for certain legal, financial, and government documents, they are slowly being phased out as digital signatures and online notarization become more secure and widely accepted. However, for critical legal documents, some international contracts, or specific sensitive agreements, wet signatures remain in use. The good news? Services like BlueNotary are bridging the gap, making notarizations easier, faster, and more secure with online options.

FAQ: Wet Signature and When Do You Need One

Why do some states still require wet signatures despite electronic signatures being available?

Some states adhere to traditional legal frameworks, viewing handwritten signatures as more secure, particularly for sensitive documents like wills and property deeds. This prevents fraud and provides authenticity for these critical agreements.

How do electronic signatures provide security compared to wet signatures?

eSignatures use encryption, biometric verification, and secure authentication protocols to ensure signer identities. BlueNotary, for example, uses these technologies, making eSignatures difficult to tamper with or forge, unlike wet signatures.

What are the environmental benefits of using electronic signatures over wet signatures?

Electronic signatures reduce the need for paper, printing, and physical storage, contributing to conservation efforts and lowering the carbon footprint. They also eliminate the need for mailing or courier services, reducing emissions from transport.
