E-signatures for legal professionals
When signatures end up in court, the audit trail matters more than the ink. SignOwl generates PAdES-B-B digital signatures with SHA-256 hash verification — the same standard used in EU qualified electronic signatures.
The problem with existing solutions
- Clients expect convenience but lawyers need enforceability
- Standard e-signature tools lack proper audit trails for litigation
- Wet signature logistics delay closings and filings
- Need to verify document integrity months or years later

Frequently asked questions
What signature standard does SignOwl use?
PAdES-B-B (PDF Advanced Electronic Signatures - Baseline). This is the baseline profile of the European ETSI standard, providing embedded digital signatures within the PDF that can be verified independently.
How long are audit trails retained?
Audit trail data is stored indefinitely. The SHA-256 hash verification page remains accessible permanently, allowing document integrity verification at any point in the future.
Can I white-label the signing experience?
Yes. Business plan includes custom branding. Your firm's logo and colors appear on signing pages and notification emails.
