Electronic Signature for Lawyers and Legal Professionals

A profession where evidence is critical

Law firms handle daily documents of high evidentiary value: fee agreements, mandates ad litem, settlement protocols, lawyer deeds. Electronic signature brings superior rigor 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 lawyer deed (specific procedure)

• Collaboration contracts (between lawyers or with partners)

• Partnership agreement (law firm creation, shared office companies)

• Official correspondence (engagement letter, validated legal opinion)

Recommended level

Advanced signature (AES) covers the majority of deeds. For electronic lawyer deed (enhanced proof regime under Civil Code article 1374), qualified signature (QES) is recommended.

Benefits for the firm

• Case acceleration: fee agreements signed in minutes

• Reinforced proof for litigation (auditable trail)

• Remote signature: client signs from anywhere

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

CNB Ethics

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

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

Frequent mistakes

• 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 processes 40 new cases per month. New workflow:

• First client meeting (video or in-person)

• Fee agreement sent in AES immediately after

• Client signs before leaving the waiting room

• Case opened in Secib with archived agreement

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