This section applies to a transfer of land forming part only of a holding of land, where—
Subject to subsection (3) below, if the transferor so claims, the transfer shall not be treated for the purposes of this Act as a disposal, but all sums which, if it had been so treated, would have been brought into account as consideration for that disposal in the computation of the gain shall be deducted from any expenditure allowable under Chapter III of Part II as a deduction in computing a gain on any subsequent disposal of the holding.
A claim under subsection (2) above shall be made—
This section shall not apply—
No account shall be taken under subsection (3) above of any transfer of land to which section 243 applies.
In relation to a transfer which is not for full consideration in money or money's worth "the amount or value of the consideration" in this section shall mean the market value of the land transferred.
For the purposes of this section the holding of land shall comprise only the land in respect of which the expenditure allowable under paragraphs (a) and (b) of section 38(1) would be apportioned under section 42 if the transfer had been treated as a disposal (that is, as a part disposal of the holding).
In this section references to a holding of land include references to any estate or interest in a holding of land, not being an estate or interest which is a wasting asset, and references to part of a holding shall be construed accordingly.
