Financial institutions, including banks, brokerage firms, and investment advisers, are working with elder advocates, regulators, and law enforcement to develop effective means to prevent exploitation of investors. A great deal of the exploitation is by persons known and trusted by elders. In this chapter, we will cover how financial institutions are training financial advisors and other personnel to take action when they become aware of various red flags. We will also cover the laws that limit financial institutions’ ability to take actions, as well as the new tools that will allow financial institutions to partner with Adult Protective Services and others to take steps to prevent financial exploitation. The chapter will also cover how federal and state financial institution regulators are engaging.
