Is he or any of his specialists considered an expert witness in credit-related litigation?

He did recommend that I save all my files from my account before closing my account, just in case we need it for court.And a side note: Bigger Pockets community has been great through this, but let's try to keep it civil and focus on passing on helpful information for those defrauded and to those unsure of what to do next.

Look up their team too, lots of litigation, internal struggle for power and inadequate leadership.

@Donnie McGriffI Google their name, I search county court records for their name (criminal and civil), I search social media sites for any information I can find. 

If you must have a formal service provided, handed to them, you might be out of luck.As Steve said, you have a timeline, small claims in civil matters is generally three years, but tenants may be specifically addressed and it could be shorter, I wouldn't think less than a year.Your lease should include costs of collection.

There is a variety of civil penalties that can be assessed based on the facts and circumstances of a particular tax scheme.

If you are setting this up with a friend/relative or employee the exception may apply and you will structure the relationship quite differently--usually with some sort of shared account.If you don't know this property manager, they should be licensed otherwise they may be operating illegally and you have no recourse other than litigation for financial misdeeds.  

In CA for example, the penalties for usury, which can result from lending without a license, can be both civil and criminal.
