Good idea. Get a will. You do not want JW family giving your estate to WTBT$
I know here in New Mexico, U.S.A if you do not make a will, your estate automatically goes to your kids first and if there is no heir then it goes to your parents [if surviving] but if not, your siblings.
There is no way in hell that I want any of my JW family getting my property. If any heirs listed in my will do not survive me, then it goes to the St Jude's Children's research hospital. They never charge the families to treat the kids.
