Electronic signature for lawyers and legal professionals

A profession where evidence is paramount

Law firms handle documents with high evidential value on a daily basis: fee agreements, mandates ad litem, settlement protocols, attorney documents. Electronic signature brings greater rigour than paper — timestamped traceability, cryptographic hash, 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 attorney document (specific procedure)

• Collaboration agreements (between lawyers or with associates)

• Partnership deed (firm creation, joint practice companies)

• Official correspondence (engagement letter, certified legal opinion)

Recommended level

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

Benefits for the firm

• Faster case handling: fee agreements signed within minutes

• Enhanced evidence for litigation (auditable trail)

• Remote signing: 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 Regulations (RIN) impose no paper requirement.

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

Common mistakes

• Using SES for a high-stakes fee agreement

• Storing documents on a US cloud (Cloud Act issue)

• Failing to activate encryption at rest for correspondence

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

Real-world example: 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 immediately after

• Client signs before leaving the waiting room

• File opened in Secib with agreement archived

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