Devon -
I couldn't get the link to work.
In answer to your question about next of kin, the KH's are owned by corporations - which don't direct rights of survivorship to family members - unless specified in the corporation filings. And in this case, I would be shocked if that is the case - most likely, the corporation itself has rights of survivorship. So, if say, a Director dies, whether someone else from the congregation is named in their place or not, the corporation would still own the KH.
I can't remember which state you are in, but you can check your Secretary of State's website for the corporate filing to find out who the most current Directors, et al are. The deeds themselves are not necessarily updated as to who controls the corporation - as long as the deed specifies just the name of the corporation. So, in order to know who they are, you would need to find the latest Corporate filing with the Sec of State. If they haven't updated the filing since the death of this elder, then the corporation (most likely) would still own the building, but with only two officers instead of three. If they all died at the same time in a trainwreck, the provisions as set forth in the Corporate Filings would determine ownership. And I would betcha that that is when the WT would then step in - at least until a new board of directors could be elected.
Hope that helps!
