I don't stay "up to date" in the way you mean. As you are doing the documents, they tend to be pretty self explanatory, if you take the time to read it before going to the closing, whenever you have time. But, I can tell you that if the correct documents aren't given to me before I leave for the closing, then that is on the Title company. I don't know what all they need to have in the package and it isn't my responsibility to know it. I generally will know if the legal documents aren't in the package: CD, Mortgage, Note, Right to Cancel forms. But beyond that, I am not required to know the correct documents that need to be included.
That especially holds true now that we are starting to see more hybrid or online closings. When you do a hybrid closing, many of the documents are signed online and I only have to have them sign a few in my presence. So, some of the documents won't be in my package (like the closing disclosure). This is just my humble opinion but it works for me!
