Translate a Legal Letter

A letter from a solicitor, the council, or a government body lands on the mat, formal and faintly threatening. This translates it: who sent it and on what authority, the core message in one line, and the action you are actually required to take. For anyone staring at official language and unsure whether to worry.

<context>
You have received a letter from a solicitor, council, or government body. The language is dense and formal. You need to understand what it says and what you must do.
