Fraudulent filings

So i have been completing the filings and paperwork for a SPC whose currently incarcerated. We are in the process of operating the trust. So ive sent out copies of his CLCRN, the SA, as well as the HHI forms followed by invocies to the judge in his case, the procecutor and the attorney general, the prothonotary office etc and we recently recieved a letter after the 3RD and final invoice was sent. They are now attempying to being him up on more charges ie a class a misdemenor im reference to fraudulent filings stating that none of the documents nor does the UCC prohibt a court officer from using his name on his docket sheets and so on. They are also claiming that it is his intent to injure or intimidate a court officer with his filings. We are well aware that with matters like these if you dont respond its possible you forfeit your rights and if you do sometimes you are now participating in business with them. The question is has anyone else recieved any letters like this and if so how did you or respond and what was the outcome? IF NO ONE HAS recieved anything like this what would be your method of response if any at all?
