Continuation of payments in certain cases

(1) If, on the application of a married person, it appears to the court that a child is or will be engaged on a course of education or training after attaining the age of eighteen years, or that the child is suffering from a mental or physical disability, and it is therefore expedient for payments to be made under an order made under section 2(d) or 9 (1), after the child attains that age, the court may order that payments be so made for such period not exceeding three years from the date of the order as may be specified in the order. (2) The period specified in an order under sub-section (1), may from time to time be extended by a subsequent order so made, but shall not in any case extend beyond the date when the child attains the age of twenty-one years.
