Continuance of payment in certain cases

(1) If, on the application of the parent or guardian of a child, it appears to the court that the child is or will be engaged in a course of education or training after attaining the age eighteen years, or that the child is suffering from a mental or physical disability, and that it is therefore expedient for payments to be made under the order after the child attains that age, then subject to subsection (2) of this section, the court may by order direct 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 made under subsection (1) of this section 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 except in the case of a disabled child or a child pursuing full time education.
