(2) If the Treasury are satisfied that at any time an undertaking given with respect to the property under section 30 above or [subsection (5AA)]¹ below has not been observed in a material respect, the failure to observe the undertaking is a chargeable event with respect to the property.

(3) If—

(a) the person beneficially entitled to the property dies, or

(b) the property is disposed of, whether by sale or gift or otherwise,

the death or disposal is, subject to subsections (4) and (5) below, a chargeable event with respect to the property.

(4) A death or disposal is not a chargeable event with respect to any property if the personal representatives of the deceased (or, in the case of settled property, the trustees or the person next entitled) within three years of the death make or, as the case may be, the disposal is—

(a) a disposal of the property by sale by private treaty to a body mentioned in Schedule 3 to this Act, or a disposal of it to such a body otherwise then by sale, or

(b) a disposal in pursuance of section 230 below,

and a death or disposal of the property after such a disposal as is mentioned in paragraph (a) or (b) above is not a chargeable event with respect to the property unless there has again been a conditionally exempt transfer of it after that disposal.

(5) A death or disposal otherwise than by sale is not a chargeable event with respect to any property if—

(a) the transfer of value made on the death or the disposal is itself a conditionally exempt transfer of the property, or

[(b) the condition specified in subsection (5AA) below is satisfied with respect to the property.] ¹

(5AA) The condition referred to in subsection (5)(b) above is satisfied if—

(a) the requisite undertaking described in section 31 above is given with respect to the property by such person as the Board think appropriate in the circumstances of the case, or
