S.No. \t Sub Agent \t Substituted Agent\n1. \t A sub-agent does his work under the control and directions of agent. \t A substituted agent works under the instructions of the principal.\n2. \t The agent not only appoints a sub-agent but also delegates to him a part of his own duties. \t The agent does not delegate any part of his task to a substituted agent.\n3. \t There is no privity of contract between the principal and the sub-agent. \t Privity of contract is established between a principal and a substituted agent.\n4. \t The sub-agent is responsible to the agent alone and is not generally responsible to the principal. \t A substituted agent is responsible to the principal and not to the original agent who appointed him\n5. \t The agent is responsible to the principal for the acts of the sub-agent. \t The agent is not responsible to the principal for the acts of the substituted agent.\n6. \t The sub-agent has no right of action against the principal for remuneration due to him. \t The substituted agent can sue the principal for remuneration due to him.\n7. \t Sub-agents may be improperly appointed. \t Substituted agents can never be improperly appointed.\n8. \t The agent remains liable for the acts of the sub-agent as long as the sub-agency continues. \t The agent's duty ends once he has named the substituted agent.
