Where at any time during the life of a person beneficially entitled to an interest in possession in settled property his interest comes to an end, tax shall be charged, subject to section 53 below, as if at that time he had made a transfer of value and the value transferred had been equal to the value of the property in which his interest subsisted.
If the interest comes to an end by being disposed of by the person beneficially entitled to it and the disposal is for a consideration in money or money's worth, tax shall be chargeable under this section as if the value of the property in which the interest subsisted were reduced by the amount of the consideration; but in determining that amount the value of a reversionary interest in the property or of any interest in other property comprised in the same settlement shall be left out of account.
Where the interest mentioned in subsection (1) or (2) above is one to which the person became beneficially entitled on or after 22nd March 2006, that subsection applies in relation to the coming to an end of the interest only if the interest is—
or falls within section 5(1B) above.
Where a transaction is made between the trustees of the settlement and a person who is, or is connected with,—
and, as a result of the transaction, the value of the first-mentioned property is less than it would be but for the transaction, a corresponding part of the interest shall be deemed for the purposes of this section to come to an end, unless the transaction is such that, were the trustees beneficially entitled to the settled property, it would not be a transfer of value.
Where the interest mentioned in paragraph (a) of subsection (3) above is one to which the person mentioned in that paragraph became beneficially entitled on or after 22nd March 2006, that subsection applies in relation to the transaction only if the interest is—
or falls within section 5(1B) above.
