Moreover, SDTC’s trust officers are highly credentialed attorneys, accountants, and trust professionals who are trained and experienced in the areas of South Dakota trust administration.

“Serving Families in Perpetuity”
Lastly, our objective is to provide “flexible, individualized, service-oriented, cost-effective trust administration”. With this in mind, we seek to tailor our services to each family, allowing us to help in the following ways:
- With newly drafted South Dakota trust laws, SDTC can act as “directed” administrative trustee, leaving the family and their advisors as the investment and distribution advisors, committees, trustees, and/or trust protectors. This allows the family to work with their existing investment and insurance advisors of their choice, and also allows SDTC to hold all types of illiquid assets (i.e., closely-held LLCs, partnerships, real estate, etc.). For additional information on the directed trust, please click here.
- SDTC can serve as successor trustee or co-trustee for trusts looking to move to South Dakota for its trust, asset protection, and tax benefits. SDTC can “delegate” investment responsibility to an outside investment manager. These trusts generally retain the trust laws of the states in which they were created for construction and validity, but are administered under South Dakota Law. Additionally, it is very easy and inexpensive to reform a “delegated” trust from another state to a South Dakota “directed” trust, if desired.

- SDTC can serve as both Corporate and/or Trustee Agent by assisting a family with the formation, operation, compliance and administration of a Private Family Trust Company (PFTC) in South Dakota (regulated) or Wyoming (unregulated and regulated), by providing the family with the necessary office space, office services (e.g., answer the phone, collect and forward mail, ect.) and local Board membership, as well as assistance with regulatory/compliance issues, trust administration, trust accounting, and custody services. The PFTC can then work with the non-South Dakota Family Office in servicing the family, typically through a servicing agreement. No one needs to move to South Dakota if SDTC is involved.
