What is a wet signature?

The act of physically signing a piece of paper, called a ‘wet’ signature because an individual signs with a pen that uses liquid ink. Some state laws, local recording jurisdictions, and individual companies require wet signatures on closing documents, but in 2000, the Electronic Signatures in Global and National Commerce Act (ESIGN) established that wet signatures and electronic signatures hold the same legal weight.
