Hi Had Enough: You asked,
"When I moved to another congregation, would my JC file get sent to it those elders?"
No, it would always stay with the original congregation. The only thing sent to your new congregation is a letter letting the new congregation Elders know your status. If for example, all your privileges are restored and no action is ongoing, then the letter will simply tell the new Elders that you are in good standing.
If some action is still pending, and say there is still a restriction, then a brief mention of what restriction remains is stated. It is up to the new congregation to restore these privileges. And they do not normally inquire into why the restrictions exist, but simply look at your performance from the time you arrived.
If a DF'd person moves, nothing is sent unless the DF person seeks reinstatement. In that case, the Elders simply write to the previous congregation for information, usually requestion help, and providing a progress report, but the new congregation will not know of the 'sin' unles the DF person decides to reveal it. The former congregation will then send a letter agreeing to reinstatement or not. In one of my Justice Series, the former congregation held out for 5 years and refused to reinstate. When I became Secretary, I discovered this, and also learned that all the original JC members moved on. So, I persuaded the Elders to reinstate, and we did.
You also asked:
"Would elders open and read the JC file of someone newly moved in?"
No. Only the original JC can read the file, or in some cases, like mine, the Secretary can read it. And I did read JC files in cases where I did not serve on the JC.
Yoiu asked about the five year file destruction,
"Is this practice actually followed through on regularly in congregations in your experiences? Or would I have to ask the elders to do so?"
It is supposed to be followed everywhere. My impression is that many Elders are good about following this procedure, but many are not. Mostly they forget and the file stays in the cabinet. Some like to keep such records, and hold them for a long time for some reason.
In practice, two Elders are supposed to witness the burning of files to be sure it is done. But, sometimes, a Secretary or other Elder will agree to burn the files, but instead take them home and hide them. I personally know of one Elder who did this, because I know for a fact that my own file is in his home office.
I have never had a Publisher ask for a file to be destroyed, mostly because they are not aware of the existence of such files. So, I am not sure what would happen if you asked the Secretary in your former congregation to burn the file. If it is older than 5 years, then it should have been destroyed.
If you are now technically not DF or DA, then you might call the Elder and ask about any records on you and what they contain, and if they have destroyed it per Watch Tower direction. But, the Elder may feel uncomfortble with such a request, because it would be very rare to here from a JW in this kind of issue. They may no want to commit to anything until the call the Society for guidance. IF you do not have a DA or DF s-77 or s-79 card with the Society, then they will probably advise the Elder to burn the file per procedure --- but only after he checks with your current congregation to determine if you ar ein good standing.
Hope this helps. - Amazing
