The answer at law is most likely no; however the answer in equity is yes. At law, there is a contract between Hotel and Person A. Person B is not a party to the contract and can generally not be held liable under the contract. The exception in law is if the Hotel asserts that Person B ratified, affirmed and assumed the contract for the rooms by its words and actions. This is a much weaker case than the case against Party A who is on the contract.
Even though the law enforces a contract as written, equity abhors people receiving and retaining a benefit for which they should not be able to retain in good conscience. “The doctrine of unjust enrichment or recovery in quasi contract applies to situations where there is no legal contract but where the person sought to be charged is in possession of money or property which in good conscience and justice he should not retain but should deliver to another [or should pay for].” Lipshie v. Tracy Investment Co., 93 Nev. 370, 379, 566 P.2d 819, 824 (1977).
