My ex-wife and I have a court order in place with the Family Court of WA ( Family Law Act 1975) for care & financial support in raising our 2 children, aged 17 & 15. This has been in place since July 2005. She has now requested an increase in what I pay her, in Line with directions from the Federal Child Support Agency. Legal advice she has obtained says that the Federal Agency Assessment will take precedence over our State Law agreement. I now only have to provide financial assistance for my 15 y.o. daughter - 17 y.o. son has moved back to live in W.A., by his own choice & the Federal Child Support have advised that neither parents have to support him financially, now. My daughter and Ex live in [location redacted by moderator] Qld. I live in W.A.
