From 1996 and within the past 16 years, there have been very significant changes in the uniform laws addressing both interstate child support and interstate custody and visitation issues. Perhaps one of the most critical laws that every family law attorney must know: the Uniform Interstate Family Support Act (UIFSA), now enacted in all jurisdictions — 755 ILCS 22/100 et. seq.; and the Full Faith and Credit for Child Support Orders Act (FFCCSOA), 28 U.S.C. § 1738B enacted in 1994 and amended in 1996. The most important of these Acts for the family lawyer to know as to jurisdictional issues is the UIFSA, which has been comprehensively amended in 2001 with more recent additional amendments in 2008 (with the 2008 amendments being to comport with requirements of the Hague Convention on the International Recovery of Child Support and Other Forms of Family Maintenance).
