What is a mandate?

A mandate is a legal document by which one person (the mandator) authorises another (the mandatary) to act on their behalf. There are many types of mandates:

  • sales mandate (property)
  • property management mandate
  • ad litem mandate (solicitor)
  • SEPA mandate (direct debit)
  • securities mandate
  • various powers of attorney

All can be signed electronically, with appropriate security levels.

  • SEPA mandate: SES is sufficient (operational importance)
  • Sales or management mandate: AES (legal and commercial importance)
  • Ad litem mandate: AES minimum, QES for solicitor acts within the meaning of article 1374 of the Civil Code
  • Securities mandate: AES, often with KYC

Procedure

  • Draft the mandate with its mandatory provisions (identity of parties, purpose, duration, remuneration if applicable)
  • Attach annexes (bank details for SEPA, surveys for property sales mandate)
  • Send for signature with the appropriate level
  • Archive the signed mandate for the appropriate duration (often 10 years)

Mandatory provisions

Depending on the type of mandate, provisions vary. Typically:

  • full identity of the parties
  • precise purpose of the mandate
  • duration and renewal conditions
  • possible remuneration
  • termination conditions
  • competent jurisdiction in case of dispute

Benefits

  • Mandate signed remotely without travel
  • Traceability of the commitment
  • Enhanced proof compared to handwritten signature
  • Automatic archiving

Common mistakes

  • Neglecting identification of the mandator (invalid mandate)
  • Forgetting the duration (indefinite mandate = terminable at any time)
  • Using SES for a property sales mandate (prefer AES)
  • Not retaining the mandate for its entire duration plus 5 years

Use case: property management mandate

A property agency signs 10-15 management mandates with property owners each month. Process:

  • Presentation meeting (in person or video call)
  • Send mandate + management agreement in AES
  • Property owner signs the same day
  • Management begins immediately

Saving: 2-4 days per file, zero travel for signature.
