One thing Mrs Tell and I have considered is donating our house and land to our church. We would reserve a joint life estate with right of survivorship in the property. We could take a nice charitable donation now and could not be kicked off the land. We have not done this yet, but it is a real possibility - ask your attorney. Of course our children may not be happy with this, but we will be safely dead.
I have a post death trust in place to care for a family member who is compromised.
I cannot leave my assets to the church as nice as it would be.
