Many Sydney firms offer a "fixed fee" initial consultation. Use this to get strategic advice on your specific situation before committing to ongoing representation.
Sydney family lawyers charge $350-$600/hour. Initial consultations cost $300-$500. A Change of Assessment application typically costs $3,000-$6,000 total. Complex court proceedings cost significantly more.
The Federal Circuit and Family Court of Australia has registries in Sydney (Lionel Bowen Building, 97-99 Goulburn Street) and Parramatta (Garfield Barwick Commonwealth Law Courts Building, 1-3 George Street). Most child support matters are heard in these courts.
You don't need a lawyer for standard assessments handled by Services Australia. However, you should hire a lawyer if you are applying for a Change of Assessment, disputing paternity, have complex income structures (trusts/companies), or if the other parent has legal representation.
