I've never heard as much, but I still wouldn't recommend you take that risk of being that rare case, just because I don't know what the punishment would be. 

Also there should be a lease otherwise it’s a verbal month to month leaseOnce you send the notice if you do not get a response and they do not vacate by the notice end date you can file for a unlawful retainer and start eviction. 

For example let's say that your tenant sued you for unlawful eviction alleging that you violated some obscure provision of the law and you didn't even know about that obscure provision so you probably did violate it.

The board will only censure, punish, or possibly suspend/revoke the license but they won't get your money back so you'll need to hire an attorney for that or sue in Small Claims Court.I suspect they'll figure it out once you file a complaint with the board.

Life punishes those who are vague, so have your goals be of what, how much of, and by when kind of things from there it is creating the plan to match the goals and working backwards and fighting to attain them.

First off, semantically  speaking, your discussion lacks a definition for the word "Legal"  While there are contracts in which a breach is a punishable offense, I am assuming you mean "Legal" in the "right to seek compensation for damages" sense.   

How your state/county views and punishes that type of breach of contract varies greatly.

I am not interested in being a party to their unlawful behaviour.He already had a large payout on a previous insurance claim that he had run out of and told me that he "had a plan".

That could result in punishment that is way worse than any potential gain here.
