(i) In general. For purposes of this paragraph (c), the term “qualified appraisal” means an appraisal document that—(1) Restricts temporarily or permanently a donee's right to use or dispose of the donated property,
(2) Reserves to, or confers upon, anyone (other than a donee organization or an organization participating with a donee organization in cooperative fundraising) any right to the income from the contributed property or to the possession of the property, including the right to vote donated securities, to acquire the property by purchase or otherwise, or to designate the person having such income, possession, or right to acquire, or
(3) Earmarks donated property for a particular use;(iii) Effect of signature of the qualified appraiser. Any appraiser who falsely or fraudulently overstates the value of the contributed property referred to in a qualified appraisal or appraisal summary (as defined in paragraphs (c) (3) and (4), respectively, of this section) that the appraiser has signed may be subject to a civil penalty under section 6701 for aiding and abetting an understatement of tax liability and, moreover, may have appraisals disregarded pursuant to 31 U.S.C. 330(c).
(iv) Special rules—
(4) Appraisal summary—
(i) In general. For purposes of this paragraph (c), except as provided in paragraph (c)(4)(iv)(A) of this section, the term appraisal summary means a summary of a qualified appraisal that—(ii) Information included in an appraisal summary. An appraisal summary shall include the following information:(1) The fee charged for the appraisal is not of a type prohibited by paragraph (c)(6) of this section; and
(2) Appraisals prepared by the appraiser are not being disregarded pursuant to 31 U.S.C. 330(c) on the date the appraisal summary is signed by the appraiser; and(iii) Signature of the original donee. The person who signs the appraisal summary for the donee shall be an official authorized to sign the tax or information returns of the donee, or a person specifically authorized to sign appraisal summaries by an official authorized to sign the tax or information returns of such done. In the case of a donee that is a governmental unit, the person who signs the appraisal summary for such donee shall be the official authorized by such donee to sign appraisal summaries. The signature of the donee on the appraisal summary does not represent concurrence in the appraised value of the contributed property. Rather, it represents acknowledgment of receipt of the property described in the appraisal summary on the date specified in the appraisal summary and that the donee understands the information reporting requirements imposed by section 6050L and § 1.6050L-1. In general, § 1.6050L-1 requires the donee to file an information return with the Internal Revenue Service in the event the donee sells, exchanges, consumes, or otherwise disposes of the property (or any portion thereof) described in the appraisal summary within 2 years after the date of the donor's contribution of such property.
(iv) Special rules—(1) Complies with the requirements of paragraph (c)(4)(i) (A) and (B) of this section,
(2) Includes the information required by paragraph (c)(4)(ii) (A) through (H) of this section,
(3) Includes the amount claimed or reported as a charitable contribution deduction, and
(4) In the case of securities described in paragraph (c)(7)(xi)(B) of this section, also includes the pertinent average trading price (as described in paragraph (c)(7)(xi)(B)(2 )(iii) of this section).(2) In rare and unusual circumstances in which it is impossible for the taxpayer to obtain the signature of the donee on the appraisal summary as required by paragraph (c)(4)(i)(B) of this section, the taxpayer's deduction will not be disallowed for that reason provided that the taxpayer attaches a statement to the appraisal summary explaining, in detail, why it was not possible to obtain the donee's signature. For example, if the donee ceases to exist as an entity subsequent to the date of the contribution and prior to the date when the appraisal summary must be signed, and the donor acted reasonably in not obtaining the donee's signature at the time of the contribution, relief under this paragraph (c)(4)(iv)(C)(2) would generally be appropriate.
