I just closed out a trust I trusteed for about 30 years.
My recommendation..
There is no easy way to get track of who gets what as soon as one person takes out money early. I would leave the trust alone and give funds to each child through a 529 plan. (A trust with government controls rather than Grandma, Aunt or Uncle controls).
It’s inexpensive to manage, lets people take responsibility for their own decisions, and reduces the number of trust tax returns and trust taxes.
When taxes were high and 529 plans (and IRAs) didn’t exist trusts made lots of sense. But today you can simplify the picture. 30 years of tax accountant fees and taxes adds up to a
Out of money.
