Electronic signature for lawyers and legal professionals

A profession where evidence is paramount

Law firms handle documents daily with strong evidentiary value: fee agreements, mandates ad litem, settlement protocols, deeds of attorney. Electronic signature brings superior rigour compared to paper — timestamped traceability, cryptographic fingerprint, long-term archiving.

Documents signed by lawyers

• Fee agreement (mandatory for certain matters)

• Mandate ad litem (power of attorney to represent in court)

• Settlement protocol (transaction)

• Electronic deed of attorney (specific procedure)

• Collaboration contracts (between lawyers or with partners)

• Partner pact (law firm creation, shared service companies)

• Official correspondence (engagement letter, validated legal opinion)

Recommended level

Advanced signature (AES) covers the majority of deeds. For electronic deed of attorney (strengthened evidence regime of Civil Code article 1374), qualified signature (QES) is recommended.

Benefits for the firm

• Accelerated case handling: fee agreements signed within minutes

• Strengthened evidence for disputes (auditable trail)

• Remote signature: the client signs from anywhere

• Centralised file: integration with legal software (Secib, Néo, Septeo)

CNB ethics

The National Bar Council fully recognises electronic signature for fee agreements. The National Internal Regulation (RIN) imposes no paper requirement.

Caution: confidentiality of lawyer-client correspondence remains protected by professional privilege. Verify that the platform encrypts documents in transit and at rest.

Common errors

• Using SES for a high-stakes fee agreement

• Storing documents on an American cloud (Cloud Act issue)

• Not enabling encryption at rest for correspondence

• Forgetting long-term retention (30 years for client files)

Concrete case: fee agreement

A firm of 8 lawyers handles 40 new cases per month. New workflow:

• Initial client meeting (video or in-person)

• Fee agreement sent in AES straight away

• Client signs before leaving the waiting room

• Case opened in Secib with the agreement archived

Rate of "cases blocked due to unsigned agreement": dropped from 15% to 0.
