A closing protection letter is the underwriter telling the lender, and in many states the buyer and seller as well, that if their own approved agent mishandles the closing, the underwriter will cover certain losses. It reaches things like the agent failing to follow written closing instructions, or fraud or dishonesty by the agent in handling funds and documents. So your read is right that it is about the settlement agent rather than about the property. The title policies answer the question of who owns this and what is against it. The CPL answers the question of what happens if the person holding everyone's money at the closing table does something wrong with it. That is why the lender wants one on nearly every financed transaction. They are wiring a large sum to a small independent agency they have never met, on the strength of that agency being appointed by a national underwriter. The CPL is the underwriter standing behind that appointment. The separate fee exists because it is a separate instrument with its own charge, and in most states the agent remits that fee to the underwriter in full rather than keeping a share. Availability, wording, and who can be named vary by state, and some states set the CPL fee by regulation, so check how your state handles it before the exam and certainly before you are the one issuing them. One thing that trips people up is that the CPL does not cover the agent going out of business generally, and it does not cover bad judgment about title. It is aimed at the closing conduct.
