Frequently Asked Questions
Are electronic signature waivers legally binding?
Yes — in all 50 US states under the ESIGN Act and UETA. Courts consistently uphold electronically signed waivers when the signer had a clear opportunity to read the terms and the signature is attributable.
Can minors sign electronic waivers?
Minors cannot sign binding waivers — a parent or guardian must sign on their behalf. Include a parent/guardian signature section in your waiver template. Some states further restrict waiver enforceability for minors regardless of parental consent.
What makes a waiver enforceable?
Specific risk identification (not vague catch-alls), clear and conspicuous presentation, voluntary signing with opportunity to read, proper identification of the releasing parties, and a complete audit trail with timestamps.
