Where any property is subject to a contingent right in an unborn person or class of unborn persons, who, on coming into existence, would in respect thereof become entitled to or possessed of the property on any trust, the Court may make a vesting order releasing the property from the contingent right, or vesting in any person the estate or interest to or of which the unborn person or class of unborn persons would, on coming into existence, be entitled or possessed in the property.
