Answer:
The answer is: An appraisal the practitioner prepared in connection with the client's 2013 federal income tax return.
Step-by-step explanation:
IRS Circular 230, § 10.28 Return of client’s records.
(a) In general, a practitioner must, at the request of a client, promptly return any and all records of the client that are necessary for the client to comply with his or her Federal tax obligations. The practitioner may retain copies of the records returned to a client. The existence of a dispute over fees generally does not relieve the practitioner of his or her responsibility under this section.
At the request of the client the practitioner must return all the records related to the client's 2013 federal income tax return and any appraisal prepared in connection to those records.
