What does wet signature mean?

A wet signature (also called a wet-ink signature) is a handwritten signature made with a pen directly on paper. The term "wet" refers to the ink being literally wet when applied.

Wet signatures are the traditional form of document authentication. Today, most everyday business contracts can be signed electronically with equal legal effect in many jurisdictions.

What does wet signed mean?

Wet signed describes a document executed with pen-on-paper signatures rather than an e-signature workflow. You might hear "return a wet-signed copy" or "we need wet ink on the original."

When is a wet signature required?

Some documents still require wet ink: wills, many notarized originals, certain court filings, some real estate title transfers, and specific government forms. Rules vary by jurisdiction.

Use e-signatures by default

For most business documents, electronic signatures are legally equivalent in many contexts, faster, and stronger for evidence. Reserve wet signatures only where the law explicitly requires them.
