They are forcing me to defend myself against a blatent lie.
So you prove the lie in court and you win the case.
Can I bring charges against my former tenant and her lawyer for this lie?
You can't bring criminal charges but there might be civil penalties against both the lawyer and the tenant for bringing a frivolous lawsuit.
Is this fraud, libel, and or extortion? Can my former tenant and/or her lawyer be disbarred for doing this?
No and no.
There's just one thing that you have to understand.
The statute might not apply to you but common law does.
Which means that the court would likely apply the same standards to the security deposit issue as the statute does.
So if you didn't handle the security deposit in accordance with the statute even though the statute doesn't apply to you, you might be in for a very unpleasant surprise.
If you want to explain the security deposit issue, you might get some comments about your side of the case.
