Notes
More Than Money Trust Company, Inc. is on the South Dakota Division of Banking September 2026 roster as a public trust company (TC.071-2), first issued 29 March 2012, at 4418 S.

The directed-trust story is explicit. The trusts page describes South Dakota Directed Asset Protection Dynasty Trusts and says the Administrative Trustee does not have the power to make any decisions — it acts on Investment Committee, Distribution Committee, Trust Protector, and SPE directions. The public offering is values-based administration, not a directed-only product menu with published fees. Confirm the current legal name is the signer. This page does not invent fees or AUM.
What to verify next
Confirm credential TC.071-2 and that More Than Money Trust Company, Inc. — not the former Argonne Trust Company, Inc. name, and not a New York 646 letterhead — is the appointed South Dakota trustee. Get the seat in writing. The trusts page publishes a directed Administrative Trustee that acts on Investment Committee, Distribution Committee, Trust Protector, and SPE directions and “does not have the power to make any decisions.” Ask who sits on those directing seats and where the file is actually administered. Ask for a current fee schedule; do not invent fees. Omit AUM.
