eIDAS compliance levels — which one for leases?

Level	Description	French leases
SES (Simple)	Click-to-sign — weak identification	Not compliant with Decree 2024-127
AES (Advanced)	OTP SMS + qualified certificate	✅ FairePlace — mandatory since Jan 2025
QES (Qualified)	eID card — highest assurance	Optional for commercial leases

How does FairePlace compare to Yousign for leases?

Yousign ~0.70€/signature + 49€/mois. FairePlace: lease + IRL + receipts in same plan.

Is the e-signature legally binding in France?

Yes. Under French Civil Code articles 1366-1367 and EU Regulation 910/2014 (eIDAS), an Advanced Electronic Signature has the same legal value as a handwritten signature.

What happens if a signer does not receive the OTP?

Use POST /leases/{id}/signature/resend/{type} — up to 5 resends are allowed. The resend count and remaining attempts are exposed in the response.
