Our attorney wrote us back and said to leave the letter "as is" and send it. He said he is curious to see what happens and how they respond. If we don't get anything back from them within a week, he will follow up with the school to make sure that DH's concerns were addressed. 

We sent it yesterday via email and sent the original in the mail. We haven't heard a peep- so I am anxiously waiting to see what will happen now. 

Backstory if you missed it: SS's IEP and 504 meeting were recently held. DH was on the conference call. BM's new husband signed the attendance and "Legal Educational Decision Maker" as "Dad" on the IEP. The 504 plan was sent to DH for his signature (we don't understand why BM's H signed one and not the other, other than DH requested written copies of both). The 504 plan dated in December stated SS had Dyslexia (never evaluated or diagnosed) and POTS (magically resolved almost 2 years ago now when DH spoke to the doctor and informed them of the lies BM tells all doctors). We sent the proof of the medical stuff, a strongly worded letter and contested the 504 and that BM's H be removed from the form as decision maker and edited to say "Step Father". The IEP was only for speech, which he has always had a slight impediment when he speaks quickly, and that is what it is- the speech therapist said there really isn't any more she can do and will do a few checks on him throughout the year.

The letter did inform the school about the ongoing health department criminal plagiarism case going on with BM, and that is why this all needs to be taken seriously.
