South Dakota
Directed Trust Governance Guide

South Dakota identifies several advisers and a protector; “trust adviser” is not one universal role.

Section 55-1B-1 defines the principal directed-trust offices, and §§ 55-1B-9 through 55-1B-13 address investment, distribution, family, and tax advisers. Under § 55-1B-10, investment authority can include retention, purchases and sales, voting, and management. Distribution authority appears in § 55-1B-11. The tax adviser recognized in 2025 receives only the powers the instrument assigns within § 55-1B-13.

One individual may hold multiple offices where the document allows it, but overlapping roles deserve a conflict review. Control of a family company, discretion over payments to an employee-beneficiary, and power over related tax elections can collide. Every written direction should name the capacity being used.

The office framework appears in SDCL §§ 55-1B-1 and 55-1B-9 through 55-1B-13.

Decision, direction, consent, disapproval, consultation, implementation, custody, and reporting are different functions.

State whether a person directs, must consent, may veto, or merely gives nonbinding advice. Section 55-1B-4 addresses fiduciary status for adviser direction, consent, and disapproval, while § 55-1B-2 concerns an excluded fiduciary. A title without operative authority creates uncertainty rather than governance.

Map the complete transaction. A beneficiary may initiate a request, the trustee may collect information, a distribution adviser may decide, and the trustee may pay, withhold tax, and report. Identify required facts, delivery deadline, authentication, conflicts, implementation, and final record for every recurring decision.

• Actor, legal capacity, and exact decision
• Purpose, standard, and conflict procedure
• Information owner, format, and deadline
• Implementer, custodian, reporter, and evidence file

An excluded fiduciary receives statutory protection for allocated functions, not universal freedom from responsibility.

Section 55-1B-2 generally limits an excluded fiduciary’s liability for authorized directions and removes duties to monitor, advise, warn, or investigate within the excluded function, subject to its qualifications and the trust. The accurate conclusion names the function; it does not say that an administrative trustee has no duties.

Custody, account opening, payment execution, statements, tax reporting, and records may remain with that trustee. The file should demonstrate that each instruction came from the proper actor, concerned assigned authority, met document requirements, and was carried out correctly.

SDCL § 55-1B-2 reallocates stated duties and liability without excusing work the instrument leaves with the actor.

The statutory menu enables a protector design; only the instrument grants an actual power.

Section 55-1B-6 lists possible authority involving fiduciary appointments, tax and administrative amendments, beneficial interests, powers of appointment, termination, distributions, situs, and governing law. Do not infer that the entire list belongs to every protector.

For each granted power, state fiduciary or nonfiduciary classification, permitted purpose, decision standard, conflicts, required information, compensation, resignation, removal, succession, and written exercise. Under § 55-1B-7, an adviser or protector accepting office submits to South Dakota jurisdiction for trust matters.

• Enumerated authority tied to an identified need
• Capacity and standard for each exercise
• Conflict, removal, vacancy, and emergency rules
• Notice, signature, authentication, and permanent retention

Legal allocation succeeds only when the providers share a repeatable, authenticated decision workflow.

A direction should identify the trust, signer, office, governing clause, asset or beneficiary, decision, effective date, supporting material, conflicts, and relevant tax or legal review. Establish approved communication channels, identity checks, and signature rules. A message from an unknown address should never be sufficient authority for a major distribution or private-asset sale.

Create escalation paths for ambiguous, incomplete, conflicting, unlawful, or impossible instructions. State who can seek South Dakota court instructions and what happens to the asset or request in the meantime. Provider engagements should implement the instrument rather than silently rewrite it.

Before execution, simulate an emergency payment, a contested company valuation, and an adviser vacancy to expose workflow gaps.

Separate offices add value only if expertise, speed, continuity, and accountability outweigh added fees and handoffs.

A family investment adviser can retain authority over a company or portfolio while a South Dakota institution handles custody and administration. The same design can create duplicated minimum fees, slow approvals, fragmented records, and conflicts. Compare proposals with identical facts and a shared responsibility chart.

Review the architecture after resignation, beneficiary relocation, a business sale, major payment, tax change, or repeated instruction delay. Every successor must be legally eligible and willing to accept the assigned function. Where no candidate exists, the instrument needs a valid route to consolidate or reallocate power.

Identify the emergency actor when a required adviser is unavailable; silence in the instrument is not a succession plan.
