I believe these documents are addressed to one specific congregation
The main issue shows up in the Articles of Association and Bylaws, Article 2 Existence and Duration.
"Since 1989 the Congregation has been an unincorporated nonprofit association."
Legally an Unincorporated Association is a group of people who get together to do something for the common good. Legally it doesn't exist so it can't do things like own property.

So for the last thirty-one years this congregation has operated without any legal authority to do so. It can't open a bank account, collect money, own property etc. I can think of at least two ways they got into what is probably a fair sized legal mess. They may never have filed the appropriate paper work when the congregation formed in 1989, or that may have been the year somebody forgot to file a renewal, and it fell off the radar at that time.
I can think of several ways the water rights may fit into this, but lacking evidence I won't speculate.
I do not believe this is part of some big conspiracy, but it does speak to the incompetence of the WTBS in running their business. Thirty-one years is a long time to overlook something this important. How important? Again I won't speculate, but I've seen property lost in foreclosure and/or bankruptcy because some paperwork was missing. How would you like to be on the body of elders that gets to explain that to the head office?
