260Apportionment of relief under section 259
(1)Where for any year of assessment two or more individuals are entitled to relief under section 259 in connection with the same child—
(a)the amount referred to in subsection (2) of that section shall be apportioned between them; and
(b)the deduction to which each of them is entitled under that section shall, subject to subsection (2) below, be equal to so much of that amount as is apportioned to him.
(2)Where for any year of assessment amounts are apportioned to an individual under this section in respect of two or more children, the deduction to which he is entitled for that year under section 259 shall be equal to the sum of those amounts or the amount referred to in subsection (2) of that section, whichever is the less.
(3)Any amount required to be apportioned under this section shall be apportioned between the individuals concerned in such proportions as may be agreed between them or, in default of agreement, in proportion to the length of the periods for which the child in question is resident with them respectively in the year of assessment; and where the proportions are not so agreed, the apportionment shall be made by such body of General Commissioners, being the General Commissioners for a division in which one of the individuals resides, as the Board may direct, or, if none of the individuals resides in Great Britain, by the Special Commissioners.
(4)Where a claim is made under section 259 and it appears that, if the claim is allowed, an apportionment will be necessary under this section, the Board may if they think fit direct that the claim itself shall be dealt with by any specified body of Commissioners which could under this section be directed to make the apportionment and that the same Commissioners shall also make any apportionment which proves to be necessary; and where a direction is given under this subsection no other body of Commissioners shall have jurisdiction to determine the claim.
(5)The Commissioners making any apportionment under this section shall hear and determine the case in like manner as an appeal, but any individual who is, or but for the provisions of this section would be, entitled to relief in connection with the child shall be entitled to appear and be heard by the Commissioners or to make representations to them in writing.
(6)For the purposes of this section an individual shall not be regarded as entitled to relief under section 259 for any year of assessment in connection with the same child as another individual if there is another child in connection with whom he, and he alone, is entitled to relief under that section for that year.
