Broker’s mark-up

Legal mark-up

Not to be confused with a legal mark-up, an impenetrable melange of passives, passive-aggressives, redundancies, flannel and non-sequiturs injected into a perfectly sensible contract by a perfectly tedious attorney. The sheer inscrutability of one’s mark-up is a criteria for inhouse legal team of the year.

Legal Mark up, being the written fossil record of a legal negotiation, a striking similarity with a schoolyard argument, or 1 tween 12-year old siblings. It will start as a broad, wide-ranging, harangue, besides adopting fundamentally opposed positions and summoning quiet outrage that their perspective is not accepted. As the absurdity of either sides position becomes apparent there is a slow careful process of reversing comet the way one 1AX down a rickety ladder on the side of a hill, and at the end resolves into to Petra learnt snickering comma correcting split infinitives and adding celery for the the main purpose of having the last word.

No? — in Financial products Markup Language.
