I remember when I began researching this material. It took years to finally get a copy of the Letter of Understanding. It was a very frustrating experience.
When I finally found a healthcare facility that had one of these documents known to be approved by Watchtower for use by JWs, I was sent through the proverbial ringer with questions about why I wanted the form document. I finally asked the institutional contact whether she had affiliation with Watchtower because of hesitancy to share a document that should be freely available to anyone who asks. I finally received the form document with a lame explanation about why I was plied with questions about my request. I never received an answer to whether the institutional staff member had affiliation with Watchtower. But I finally did receive the document, which I was thankful for.
