IMO, if I were you, since all is governed now by contract/trust (and not by law), I would create a contract/trust with any agency/party that is trespassing against me, the man, and get this contract/trust (which is usually ratified by their silence/acquiescence) recorded in the county recorder's office so it becomes admissible substantive evidence.
I would create an "Affidavit in Support of the Lawful Money Reduction on Federal and State Tax Returns". Use this affidavit to give you a template for the format and content thereof.
I would also follow this procedure to establish my status to perform the same.
This claim, upon modification, may be a remedy for curing said trespass.
IMO... It is better to create a pro-active, substantive record. This record should begin with this letter, modified for using LM. Then use the Fault and Default letters.
I would not "argue" (discuss) this over the phone with anyone... such recorded proceedings, IMO, are a trap. A substantive, non-hearsay record must be created with the intent to enforce a trespass against the "man".
Others in this group may have better solutions, and I hope they will respond to you... in accord with Prov 11:14
14 Where no counsel is, the people fall : but in the multitude of counsellors there is safety.
