Yes that is true.
Guys several people in the thread have explained how the trust works, but every 3 posts someone says something that is against the correct information. I know that it is hard to read big threads, but here you just have to go back about 2 pages.
Please remember this money cannot be taken out by Katherine or the kids. This money is to fund the trust. More money will be added to the trust, so you cannot do math by subtracting the cost of a house, etc., from the amount and say the kids will end up with X amount.
Katherine cannot go into it and take out money to buy a house, car, or give to the children.
Katherine cannot leave her share to her heirs. When she dies the money goes into the kids trust.
Katherine gets an allowance now and it will be continued.
Kids get an allowance and it will be continued.
If anyone thinks of more please add.
