What is a Mandate?
A mandate is a legal act by which one person (the principal) gives another person (the agent) the power to act on their behalf. There are many types of mandates:
- sales mandate (real estate)
- property management mandate
- ad litem mandate (attorney)
- SEPA mandate (direct debit)
- securities mandate
- various powers of attorney
All can be signed electronically, with appropriate security levels.
Recommended Signature Level
- SEPA Mandate: SES is sufficient (operational stake)
- Sales or management mandate: AES (legal and commercial stake)
- Ad litem mandate: AES minimum, QES for attorney acts under Article 1374 Civil Code
- Securities mandate: AES, often with KYC
Procedure
- Draft the mandate with its mandatory provisions (identity of parties, object, duration, remuneration if applicable)
- Attach annexes (bank details for SEPA, reports for real estate 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:
- complete identity of the parties
- precise object 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 evidence compared to a handwritten signature
- Automatic archiving
Common Mistakes
- Neglecting the identification of the principal (invalid mandate)
- Forgetting the duration (mandate of indefinite duration = terminable at any time)
- Using SES for a real estate sales mandate (prefer AES)
- Not retaining the mandate throughout its duration + 5 years
Use Case: Property Management Mandate
A real estate agency signs 10-15 management mandates each month with property owners. Process:
- Presentation meeting (in-person or video)
- Sending mandate + management agreement in AES
- Property owner signs within the day
- Management starts immediately
Benefit: 2-4 days saved per file, zero travel for signature.
