Stronger Version of the Truth Test Letter

Bailiffs say using this letter is "dangerous" and "amounts to blackmail".

You are asking the bailiff to pass a truth test to prove the fees you have been charged are lawful.

Either way, it creates lots of mess for bailiffs because you can start a claim in the small claims court to recover the fees regardless of what the bailiff does with this letter, even if he ignores it.

Make the bailiff pass a truth test to prove the sum demanded is compliant with the law.

If no refund, then reclaim everything in the small claims track.
