The OP says he's in the US and his funds are in the US so its not like doing this in Thailand, which I would discourage. Plenty of reputable law firms to choose from. If he gives his daughter a copy and explains the way the trust works, she could watch to make sure it happens as outlined or raise the red flag. Annual accountability can be established in the trust instructions. Can theft occur it's possible, but chances are low. He's asking for suggestions on how to solve the situation and I'm offering one. I know this can work as I was included in a family trust set up this way and all funds were paid out as instructed.
