This guide shows 5 free methods to sign any PDF electronically - all legally binding and accepted by courts, employers, landlords, and government agencies.

Are Electronic Signatures Legal?

YES - electronic signatures are legally binding in the US under the ESIGN Act (2000) and UETA. They're accepted for employment contracts, rental agreements, business contracts, loan documents, and most legal forms. Only a few documents require wet signatures: wills, adoption papers, divorce decrees, and court orders.

For legal validity, signatures must show: (1) intent to sign, (2) consent to electronic signature, (3) record of the signature process.
