Just to reiterate what I Posted above, if you are threatened with Disassociation , then this move by the Congregation is NOT Ecclesiastical.
They make that plain in the Elders Book, therefore, in this situation, a Notarised letter, or whatever it may be called in your Country, that shows you left entirely a while before any action by the Elders or Congregation, is a great tool.
You can then claim that your Human Rights, to Freedom of Thought, Conscience and Religion are being breached, also your Human Right to a Family life. Personally I would threaten to Sue any Elders, and the Congregation involved, if any Announcement were made about me, or any rumours circulated. I would claim such action is Defamation of Character.
Just a word of caution, if you threaten Legal Action, you must intend to go through with it, it is illegal to threaten with no intention of carrying out the Threat here in the U.K.
Again, Good Luck to all in this situation !
