Sub agent: An agent appointed by the original agent is called a sub agent. He is under the control of the original agent to the business of the agency (Sec 191).

Co-agent: When two or more persons are appointed as agents by the principal to act as such jointly or severally, they are called Co-Agents. Co-Agents should concur together in exception of their authority to bind the principal. Unless contrary is proved, they are jointly responsible. An agent who is appointed as co-agent must exercise some amount of discretion as a man of ordinary prudence would exercise in his own case. If he does this, he is not responsible to the principal for acts of negligence of the co-agent.

Substitute agents: (Secs 194 & 195) Where an agent holding an express or implied authority to name another person to act for the principal in the business of the agency, has named another person accordingly, such person is not a sub agent, but an agent of the principal for such part of the business of the agency as is entrusted to him. Such as agent is called substitute agent. A substitute agent is the agent of the principal and as much he is responsible to the principal.
