It is a criminal offence and you can have them imprisoned for it, even the Court Magistrate or their legal representatives!
Pursuant to UDHR Article 17, subsection 2 can no authority or any entity take your property, it must be abitrarily given (read UDHR 17 and that by law supersedes all other legislations under common laws). Tell them you want full culpable signature on any and all documents and under prenalty of perjury as to why they believe they can unlawfully take your property.
No one can ever take your property, it must be arbitrarily given, so don't let them, make it unlawful. See any decent legal rep and they will make sure it is not taken or enlighten them to the facts I am stating. Remind the court that they require either an inchoate instrument pursuant to Section 20 of the Bills Of Exchange Act so they can act as the holder in due course or supersede the Contracts (Rights of Third Party's) Act 1999, notably section 6 with UDHR Article 1 and the matter is settled in full without further prejudice, recourse or notice. Remind them that if they do not agree to this they are violating your Convention Rights (to which all primary and subordinate legislation must be read and given effect) and you have a valid law defence and can claim restitution for unlawful malfeasance. By law, no one at all can take your property, EVER! I would expect them to then accept that offer or, asthey seem to like to do, send some instrument in return giving you no lawful equitable resolution pursuant to UDHR Article 1.
