They not formally handed over to the elders. That’s what I meant (and what I said)
You used the word "access" and applied your own definition. Just wanted to clarify that personal notes are indeed "accessed" (aka looked at, used) by fellow congregation members, including elders, when organizing the territory data.
In regards to the statement "they are not formally handed over to elders", this is also not completely true. Perhaps in Europe it is a practice that WT is trying to discontinue in light of this new law/litigation, but in much of the world it has been and continues to be common practice for publishers to turn in registry and householder notes so as to be archived with the territory slips.
