The principle that renunciation before performance is due is such a breach that the party who is not in default may maintain an action thereon at once is applied in cases of contracts for personal services, or contracts to act as agent.1 It has been applied to a contract by which A employs B to act as his agent in selling real property,2 including a contract by which the agent was given the right to buy the property himself at his election.3 It has been applied to a case in which the principal repudiates a contract of sale made on his behalf by his broker and declares that he will not perform the contract and that he will not indemnify the broker against the liability to which the broker is exposed upon such contract of sale because of the fact that he has made it in his own name.4
