Banks must comply with extensive federal and state lending laws when providing loans to customers. There are over 19 separate federal laws regulating home lending alone, and the volume of regulations could reach as high as the Eiffel Tower if stacked. Bank employees such as compliance analysts undergo years of education to learn these complex rules. In contrast, most customers do not fully read or understand the dense loan documents they sign, and cannot ensure their bank followed all procedures correctly. Customers must rely on banks complying with regulations, but a single error in signed documents could harm the borrower.
