I’ll throw out some question that will hopefully help you make a determination… Are all of the statements you’re making true? Are you legally permitted to take the actions against the consumer that you’ve indiated?( Have you consulted with an attorney to ensure all statements reflect actual actions you can take.)
Similar to doing a marketing review, I would put any collection communication through a UDAAP review. The CFPB or your regulator’s exam procedures would be a good place to start.
Finally, we have a list of lending enforcement actions on the resources page of our website under “Enforcement/Lending Compliance Enforcement Actions Chart” https://mycomplianceresource.com/ultimate-compliance-resource/#toggleInfoSection. There are cased in those where UDAAP is cited for collection practices. There should be links to the enforcement action so you can dig in to find what some of their specific issues were. Generally speaking, many of them including harrasing behaviour, threatening actions that were permitted/legal, taking possession of personal items that belong to the consumer, disclosing the debt to third parties, etc, but reviewing these would give you an idea of what has caused others problems.
