Both the father and mother have a joint duty to maintain or contribute to the maintenance of
their children, whether they are in his/her custody, and whether they are legitimate or
illegitimate. The children must typically be maintained until 21 years old, although parental
responsibility for maintenance can extend over 21 years old if the child is suffering from some
mental/physical disability, serving national service, studying for their tertiary education, or some
other special circumstances.
