Legal Treatment Of Undisclosed Principals
1. Concept of Undisclosed Principal
An undisclosed principal exists where:
An agent enters into a contract without revealing that they act on behalf of another
The third party believes they are dealing with the agent as the principal
Later:
The real principal may intervene and enforce the contract
The third party may sue either the agent or the principal
2. Key Legal Principles
(a) Right to Intervene
The undisclosed principal can:
Sue the third party
Be sued by the third party
(b) Election Doctrine
The third party must eventually elect whether to proceed against:
Agent, or
Principal
(c) Defences Available
The third party can raise against the principal:
Any defence available against the agent
(d) Limitations
The doctrine does not apply where:
Identity of contracting party is crucial
Contract expressly excludes third parties
Fraud or misrepresentation is involved
3. Application in Arbitration
(a) Binding Non-Signatories
Undisclosed principals may:
Be bound by arbitration agreements
Enforce arbitration clauses
(b) Consent to Arbitration
Courts examine:
Implied consent
Commercial intent
(c) Group of Companies Doctrine
Sometimes overlaps with undisclosed principal situations.

9. Conclusion
The doctrine of undisclosed principals reflects a balance between commercial reality and contractual fairness. In arbitration, its application is more complex due to the consensual nature of arbitration agreements. Modern jurisprudence allows binding undisclosed principals where intent, authority, and fairness are established, but courts remain cautious to prevent imposition of arbitration without genuine consent.
