• Real estate sale agreement with advanced signature — notary electronic verification.

Common mistakes

• Accepting a simple signature as equivalent to a qualified one in high-risk contracts.
• Missing certified timestamp — the signature can be challenged as undated.
• Not verifying the certification chain of the issuing authority (EU-accredited CA).
• Ignoring the certificate revocation status (CRL/OCSP) at the time of signing.
