Final answer:
The legal concept that may give Principal Blanchard the right to recover money from Agent Locke is indemnification.
Step-by-step explanation:
The legal concept that may give Principal Blanchard the right to recover money from Agent Locke is indemnification. Indemnification refers to the act of compensating someone for a loss, damage, or injury they have suffered. In this case, if Locke's actions were the sole cause of the damages to the third party, Blanchard may seek indemnification from Locke to recover the money paid to the third party.
