Notes
Teton Trust Company describes itself as a Wyoming state-chartered trust company based in Jackson Hole and as an independent licensed Wyoming trustee. The Wyoming Trust Association lists it as a founding member whose board is made up of lawyers and trust professionals, and as part of a group experienced with multi-generational family trusts for clients across the globe.
The public offering includes directed trusts — Wyoming’s statute lets the instrument split the trustee from the investment advisor — plus asset-protection trusts and private family trust company work. The international/LATAM-adjacent Cone Marshall affiliation is a feature for cross-border families and a diligence item for US counsel who need to know where the work is actually done.
What to verify next
The name is on the Division of Banking roster; confirm it is still there, at the same address, when you appoint. Ask whether Cone Marshall’s non-US offices will touch administration, and how that affects Wyoming situs, tax reporting, and privileged communications. If the family wants a directed investment advisor, get the W.S. 4-10-718 excluded-fiduciary language into the instrument and confirm Teton will take the administrative seat only.
