The Indian Trust Asset Reform Amendment Act aims to improve the management of trust assets held by the federal government for Indian tribes and individual Indians. The main objective is to streamline the processes involved in managing these assets, ensuring that tribes have more control and flexibility in how they handle their resources. Key provisions of the Act include updated definitions of terms related to Indian tribes and tribal organizations. It clarifies that a tribal organization can manage trust assets on behalf of a tribe if authorized by the tribe's governing body.
