If a disposition creating a trust of land requires the consent of more than two persons to the exercise by the trustees of any function relating to the land, the consent of any two of them to the exercise of the function is sufficient in favour of a purchaser.
Subsection (1) does not apply to the exercise of a function by trustees of land held on charitable, ecclesiastical or public trusts.
Where at any time a person whose consent is expressed by a disposition creating a trust of land to be required to the exercise by the trustees of any function relating to the land is not of full age—
his consent is not, in favour of a purchaser, required to the exercise of the function, but
the trustees shall obtain the consent of a parent who has parental responsibility for him (within the meaning of the Children Act 1989) or of a guardian of his.
