Common questions

Is a signature made with Doclyx legally binding?

Electronic signatures are broadly legally valid (ESIGN Act in the US, eIDAS in the EU). Each signature is burned into the PDF with the signer's name and the signing date as a permanent caption.

Do I need an account to sign a PDF?

Your first signature is free with no account. After that, plans start at $5/month — unlimited signing is included in the $50/month Professional plan with a 14-day free trial.

Can I send a contract to someone else to sign?

Yes — that lives in the Legal workspace: your counterparty gets a secure signing link (no account needed on their side), and you can countersign afterwards. The Sign engine here is for signing your own documents.
