(1)Where in any proceedings there arises on the rule against perpetuities a question which turns on the ability of a person to have a child at some future time, then—
(a)subject to paragraph ( b), it shall be presumed that a male can have a child at the age of fourteen years or over, but not under that age, and that a female can have a child at the age of twelve years or over, but not under that age or over the age of fifty-five years; but
(b)in the case of a living person evidence may be given to show that he or she will or will not be able to have a child at the time in question.
(2)Where any such question is decided by treating a person as unable to have a child at a particular time, and he or she does so, the High Court may on an application made to it make such order as it thinks fit for placing the persons interested in the property comprised in the disposition, so far as may be just, in the position they would have held if the question had not been so decided.
(3)Subject to subsection (2), where any such question is decided in relation to a disposition by treating a person as able or unable to have a child at a particular time, then he or she shall be so treated for the purpose of any question which may arise on the rule against perpetuities in relation to the same disposition in any subsequent proceedings.
(4)In the foregoing provisions of this section references to having a child are references to begetting or giving birth to a child, but those provisions (except subsection (1)( b)) shall apply in relation to the possibility that a person will at any time have a child by adoption, legitimation or other means as they apply to his or her ability at that time to beget or give birth to a child.
(5)Subsections (1) to (4) shall apply to any question as to the right of beneficiaries to put an end to accumulations of income under any disposition as they apply to any question arising on the rule against perpetuities.
