This is probably all old news to most but I found it interesting. I was trying to find the website that has all the BOEs and in my yahoo search these showed up and I checked them out. There are probably better lines than the ones I picked out but if interested check them out.
http://wol.jw.org/en/wol/d/r1/lp-e/202012206#h=0:0-3:583 "A trustee or executor should be aware that whether the estate is large or small, liberties should not be taken with the assets. Any bequests to a legal entity used by Jehovah’s Witnesses are dedicated funds that belong to Jehovah’s organization.—Luke 16:10; 21:1-4."
I still find amusement when they just toss a bible verse after something they say. I guess the average person doesn't actually look up the verse so they walk away thinking that the bible actually says for trustees to not screw over the WT.
http://wol.jw.org/en/wol/d/r1/lp-e/2005807#h=60:0-60:250 "Gift Annuity: A gift annuity is an arrangement whereby one transfers money or securities to a designated corporation that is used by Jehovah’s Witnesses."
I have donated money to several organizations including churches. I don't think I ever recall any of them calling themselves a corporation. I guess legally that's what many are but especially when talking about a church, how many say 'donate to a corporation that used by us'.
This article also goes on to say how all the money is used. All of it is only used inside of the WT. From a quick read it looks like zero money went to helping anyone else like the hungry or any number of other community service projects that most other churches are involved in.
