UDAP is an acronym for "unfair or deceptive act or practice," a phrase in section 5 of the Federal Trade Commission Act.
Congress gave the CFPB authority to define practices within its sphere of influence that are "unfair, deceptive or abusive acts or practices" (UDAAP). The CFPB has used the FTC's guidance on what makes a practice unfair or deceptive, and added its own spin on what's abusive.
UDAAP is UDAP plus.
