Wet signature

A wet signature is a handwritten signature made with pen and ink on a physical piece of paper. The term exists mainly to distinguish it from electronic signatures; before e-signing, nobody needed to call ink signatures wet. People searching for what a wet ink signature is are usually trying to work out whether a particular document still needs one.

The process is familiar: print the document, sign by hand, and then either hand it over, post it, or scan it and send the copy. If several parties are involved, the paper travels between them or each signs a separate counterpart. Proof of who signed typically relies on handwriting, witnesses, notarization or simply the circumstances around the signing.

A freelancer might still meet wet signatures when a bank, a government office or an older firm asks for an original signed form. They print it, sign it, scan it on a phone and email it back, only to be told the original must be posted. That round trip can take a week for something an e-signature could have handled in minutes.

The biggest misconception is that a wet signature is always more legally secure. In the US, the ESIGN Act and UETA give electronic signatures the same legal effect as handwritten ones for most transactions, and eIDAS provides a similar principle in the EU. A handwritten signature is also easy to copy and hard to date, and on its own it leaves no record of when or where it was made. Wet signatures are still required for some documents, such as certain wills, some real estate filings and specific government forms, depending on jurisdiction.

Where formalities apply, a wet signature is often paired with a witness signature or notarization. Those extra steps, rather than the ink itself, are usually what give the document its added weight. It is also worth knowing that a scanned wet signature is, in a strict sense, an electronic record. Once you email a scan, you are already relying on electronic evidence, just with fewer of the records an e-signature platform would keep automatically.

Our take: wet signatures are not going away entirely, and they should not. But for most everyday agreements, an electronic signature with a clear audit trail offers better evidence than a scanned page with an unverifiable squiggle.

eSignSimple is built for electronic signing, not ink, but if you receive a scanned or printed document, our free Sign PDF tool lets you add a signature to it, and the signature generator can create a clean signature image to use. For documents that legally require wet ink, check local rules first.
