Final answer:
It is true that a CPA's work can be protected from a subpoena if the CPA is hired by an attorney, which is covered under attorney-client privilege and attorney-client work product privilege. However, the protection applies when the CPA's work is part of legal services provided.
Step-by-step explanation:
The answer to whether a CPA's (Certified Public Accountant) work is protected from a subpoena when hired by an attorney is: 1) True. This concept is known as the attorney-client privilege, which can extend to the work of a CPA engaged by an attorney as part of the legal services provided to a client, known as the attorney-client work product privilege. Effectively, if a CPA is hired by an attorney as opposed to directly by the client, the CPA's findings, reports, and notes can be protected from being disclosed in court proceedings, under certain conditions. However, it's essential to distinguish that the mere act of hiring a CPA through an attorney does not automatically make all the CPA's work privileged. The work must be part of, and in furtherance of, legal services being provided.
