Could I ask? I know a contruction: I have my documents confirmed. However, does a following form of the mentioned structure exist? Documents to be had confirmed. = Documents to have confirmed. I made them up in my head, but I can imagine an usage of it in a following context: Me: What is it laying on my table? Workmate: Boss has left you there some documents to have confirmed to the personal office. I hope my explanation was sufficient. Thank you.
