Where the reversionary estate in an agricultural holding is for the time being vested in more than one person in several parts, the tenant shall be entitled, on quitting the entire holding, to require that any compensation payable to him under this Act shall be determined as if the reversionary estate were not so severed.
Where subsection (1) above applies, the arbitrator or (as the case may be) the third party shall, where necessary, apportion the amount awarded or determined by third party determination between the persons who for the purposes of this Act together constitute the landlord of the holding, and any additional costs of the awardor determination caused by the apportionment shall be directed by the arbitratoror third party to be paid by those persons in such proportions as he shall determine.
