Is an Electronic Signature on a PDF Legal?
Yes. Electronic signatures are legally binding in most countries under:
- USA: ESIGN Act and UETA
- European Union: eIDAS Regulation
- UK: Electronic Communications Act 2000
- Most other countries have equivalent legislation
A drawn or typed signature on a PDF is legally valid for most agreements, contracts, and business documents. (Highly regulated documents like wills may require a physical signature.)
