What Is Wet Signature?
A wet signature is a traditional handwritten signature created by physically applying ink to a paper document using a pen. The term 'wet' refers to the ink being wet on the page at the moment of signing.
Wet Signature Explained
Wet signatures have been the standard method of authenticating documents for centuries. The act of physically signing a document with ink creates a unique, personal mark that is tied to the individual signer. Historically, wet signatures have served as the primary evidence of a person's intent to agree to or authorize the contents of a document.
With the passage of laws like the ESIGN Act (2000) and UETA (1999) in the United States, and eIDAS in the European Union, electronic signatures now carry the same legal weight as wet signatures for the vast majority of transactions. However, a small number of document types still require wet signatures by law, including most wills, certain court documents, and specific government forms.
Many organizations are transitioning from wet signatures to electronic signatures to reduce turnaround times, lower costs, and improve document tracking. Where a wet-signed contract might take days or weeks to circulate by mail, an electronically signed document can be completed in minutes. Despite this shift, understanding when a wet signature is still legally required remains important for compliance.

Examples

Most jurisdictions require wills to be signed with a wet signature in the presence of witnesses, making this one of the few remaining documents where ink signatures are legally mandated.
