Child Maintenance is a difficult and complex area of law. Child Maintenance can refer to:
- International Child Maintenance;
- Adult Child Maintenance;
- Child Maintenance for children whose parents separated before 1989.
International Child Maintenance is usually determined by a Court (or by agreement between the parties) and registered with the Department of Human Services (Child Support) for collection. Child Maintenance Orders from overseas jurisdictions can be registered with the Department for collection. On occasion, the registration of an overseas Order can include significant arrears.
Adult Child Maintenance is usually determined by a Court (or by agreement between the parties) for children over the age of 18 years. Orders are usually made if the child needs to complete their first tertiary course or degree, or are physically or mentally disabled.
Child Maintenance (Stage 1) cases, being those prior to 1989, have almost all concluded due to the effluxion of time. There are rare cases where arrears of Child Maintenance have been litigated.
