Your Trustee’s job is to collect your money and pay your debts and then get the money out of your trust and into the hands of the people inheriting from you.
If a young person is inheriting, you pick the age when that person gets control of their inheritance.
For anyone under that age, your trustee does not give the money to the young person, they create a new trust for that person (we call this a Young Beneficiary’s Trust) and the Young Beneficiary’s Trustee is then in charge of the money until the young person reaches the age you pick
The Young Beneficiary’s Trustee/Your Children’s Trustee makes the decisions about how inherited money is spent for the young person on an ongoing basis.
The Young Beneficiary’s Trustee/Your Children’s Trustee has to provide an annual report of the trust assets and expenses to the Custodial Guardian for your child (if under 18) or to your child (if over 18)
