Translate a Solicitor's Letter Into Plain Language

A formal letter arrives from a solicitor, written in language built to be unsettling, and you cannot tell whether you need to act or just file it. This states in plain English what the letter is about, who sent it, whether a response is required, and by when. For people in England and Wales who would rather understand the letter than panic at it.
