The notice to borrower will need to be provided (in a timely manner). I recommend sending 2 copies of the notice, with a return envelope so they can sign and return one for your records. (Since they often don't return them, you can also send this notice by certified mail. Then you would just keep the receipt of delivery in your file for proof that it was provided)
As for the option to escrow notice...that would be a Bank decision. It would not be required for a LOL map change, but you could extend the option to do so at that time.
