Can I get Child Maintenance for Adult Children over 18 Years

What happens with a Child who is part financially dependent and older than 18 years 

Child Maintenance is financial support for a dependent Child over 18 years of age.

Adult Child Maintenance can be payable if a Child over 18:

  • is studying – completing their secondary or tertiary education (including secondary school, TAFE, university, apprenticeship);
  • has a physical or mental disability; or
  • has a serious illness.



If a Child will turn 18 while they are completing their final year of secondary schooling, the parent who is receiving Child Support payments for that Child, can make an application to the Child Support Agency to extend the Child Support Assessment until the end of the school year.

That application must be made before the child turns 18.

An application for Adult Child Maintenance can be brought by a parent or the adult child. Adult Child Maintenance is paid either to:

  • the parent the Adult Child is living with;
  • the Adult Child.
