Well, I was able to look over that link a bit. Yes, it is confusing.
I do not claim to understand all of it. I have stayed up many nights trying to comprehend that crap. :p What I do know is that when researching restrictive endorsements.......you should be looking under the section "negotiable instruments". I did a little more looking in that area of the Michigan UCC and found negotiable instruments (section 3204) but where I believe the law applies is in section 3206.
Take a look and tell me if that makes a little more sense.
