Definition and Structure
A sole trader (entreprise individuelle) in Monaco is a natural person carrying out commercial, professional, or craft activities individually without forming a separate legal company. This is the simplest business structure, with minimal regulatory requirements but with exposure to unlimited personal liability.
Key Characteristics
No Capital Requirement
No minimum capital is required to begin operating as a sole trader.
No Articles of Association
Unlike company structures, a sole trader requires no Articles of Association, partnership agreements, or formal incorporation documentation.
Quick Establishment
Sole trader activities can be established rapidly with straightforward registration procedures.
Simplified Management
- No mandatory board meetings
- No shareholder approvals required
- No requirement to file separate company accounts
- No auditor appointment required (normally)
- Minimal administrative burden
Personal Liability
Unlimited Personal Liability
A sole trader bears unlimited personal liability for all business debts and obligations. This means:
- No separation between personal and business assets
- Creditors can pursue personal property to satisfy business debts
- Personal savings, home, and other assets are at risk
- Liability extends beyond any capital invested in the business
This is a critical distinction from limited liability company structures (SARL, SURL, SAM).

Comparison with Other Structures
A sole trader structure differs significantly from:
- SURL: Provides liability protection but requires capital (€8,000–€15,000)
- SARL: Requires minimum 2 shareholders and €15,000 capital
- SAM: Requires substantial capital (€150,000) and government authorisation
Sole trader status is ideal for individuals wanting to begin immediately with minimal regulatory compliance, but offers no personal asset protection.
