How it works
Tell SigningVault who's involved and what you're agreeing. The AI drafts the right contract with the right clauses.
Edit any line, swap clauses, change jurisdiction. Add signature fields with a click.
Recipients get a private signing link by email. They sign in-browser — no account, no app. You both get the sealed PDF.
Signatures made in SigningVault are recognised under UK and EU eIDAS, the US ESIGN Act and UETA. Documents are encrypted in transit and at rest, hosted in the EU and never used to train AI models.
