I'm not an attorney and this is not legal advice.

Many parents complain that they feel court ordered therapists are deceptive or dishonest.

It is important for such parents to gather evidence which can demonstrate the truth of the matter.

Possible:

Fraud

Fraud is both a civil tort and criminal wrong.

In civil litigation, allegations of fraud might be based on a misrepresentation of fact that was either intentional or negligent. For a statement to be an intentional misrepresentation, the person who made it must either have known the statement was false or been as to its truth. The speaker must have also intended that the person to whom the statement was made would rely on it. The hearer must then have reasonably relied on the promise and also been harmed because of that reliance.

If I felt my therapist engaged in unethical behavior:

How Do You Report a Therapist for Unethical Behavior?

You must contact your state’s licensing board to report a therapist for unethical behavior. Some states allow you to submit a complaint via their website, while others require it to be submitted by mail. Official complaints must be submitted in writing (i.e., online or by mail) rather than by phone. However, you can still contact the board by phone for any questions.

The board will investigate your complaint and may request evidence or conduct interviews. Suppose the board finds that your complaint is valid. In that case, the therapist will be subject to disciplinary action, including but not limited to paying a fine, getting more training, or losing their license.

However, for some people, filing a complaint may not be enough. For example, if you believe your therapist committed malpractice, you may be able to file a lawsuit against them.

I would consider the behavior of the therapist with respect to this list.
