My uncle left no will. He didn't believe in wills. The WTS promised him that the ''new order'' was always around the corner. He passed away after serving Jehovah the Watchtower Society close to 50 years.
Who knows?.. they could be talking about property issues, how they can turn your grandfather's assets into $$$ for the WT$ and they didnt want your cousin to interfere.
I would not have left if it were me, i am in support of making news out of this, contact your local news paper and spread the stupidity that exist in the WT$. Who knows how many people you would be saving out there with similar situations.
