10.—(1) A Tir Cynnal agreement holder (or, if the Tir Cynnal agreement holder has died, his or her personal representative) will notify the National Assembly in writing of any change in the occupation of the agreement land or any part of the agreement land where the change occurs while the Tir Cynnal agreement is in force.
(2) Notification under this regulation will be given within three months after the change of occupation concerned.
(3) Where there has been a change of occupation of all or part of any agreement land, and the National Assembly enters into a Tir Cynnal agreement for the remainder of the term of the original agreement with the new occupier in relation to the land the occupation of which has changed, then that agreement will, for the purposes of calculating agreement years, be deemed to have commenced on the date on which the original agreement commenced.
(4) If the new occupier decides not to enter into a Tir Cynnal agreement for the remainder of the term of the original agreement in relation to the land the occupation of which has changed, then the National Assembly may withhold the whole or any part of aid payable to the Tir Cynnal agreement holder under these Regulations and may recover the whole or any part of aid paid to him or her.
(5) The foregoing provisions of this regulation will be subject to Article 36 of Commission Regulation No. 817/2004 (which governs transfers of holdings).
