The Kennedy v. Kennedy case is a complex and lengthy legal battle that spans multiple court decisions over several years. Initially, Lillian Frances Kennedy filed a petition for separate support in Massachusetts, while George Day Kennedy filed for divorce in Arizona. The Massachusetts court found the Arizona divorce invalid due to jurisdictional issues, as George did not meet Arizona’s residency requirements. Over the years, the case involved multiple appeals and decisions regarding contempt, modification of support orders, and counsel fees. The courts addressed issues such as the validity of foreign decrees, jurisdiction, and the modification of arrearages. The case highlights the challenges of enforcing support orders and the discretion of trial courts in awarding counsel fees. Ultimately, the courts emphasized the importance of demonstrating a material change in circumstances for modifying support orders and the need for fair enforcement of arrearages.
