Annual Trust Accounting Requirements in South Dakota

At a glance

Requirements one by one

South Dakota separates unsupervised accounts from supervised reports

For a trust outside court supervision, SDCL § 55-3-45 does not set an annual, termination, vacancy, or change-of-trustee delivery deadline. Instead, it defines an interim or final accounting and gives a consequence when the trustee elects to send one with the required notice.

Court supervision changes the rule. A “court trust” is one established or confirmed by a court judgment, decree, or order under SDCL § 21-22-1. The court-trust trustee's initial filing begins supervision under SDCL §§ 21-22-3 and 21-22-6. A fiduciary, trustor, or beneficiary of another trust may petition for supervision under SDCL § 21-22-9 when the trustee is a South Dakota resident or trust property has a South Dakota situs.

Once supervision exists, SDCL § 21-22-14 requires the verified annual report within 120 days after each year measured from the start of supervision. The trustee may instead report in the first four months of a year for the prior calendar year. SDCL § 21-22-15 separately requires a verified final report when the estate is disposed of or the instrument's provisions have been carried out. The court may require a special report on petition under SDCL § 21-22-13.

The two tracks have different content rules

An unsupervised accounting under SDCL § 55-3-45 must reflect all transactions, receipts, and disbursements during its period, list assets at period end, and include written notice of that section's approval rule. The recipient is a “distribution beneficiary,” defined by SDCL § 55-1-24(2) as an eligible or permissible distributee of trust income or principal.

For a supervised trust, the annual report must detail receipts, disbursements, and acts. The final report may incorporate earlier reports by reference but must complete them with an itemized statement of all receipts, disbursements, and trustee acts. SDCL § 21-22-30 uses the same core transaction, receipt, disbursement, period, and ending-asset elements when defining a court-approved accounting.

Delivery depends on whether the accounting is in court

For the unsupervised route, SDCL § 55-2-24 permits personal delivery, prepaid U.S. mail, fax, electronic communication, or internet or application posting paired with separate compliant notice. It does not make certified mail or a nonparty adult server the general rule.

For a supervised report, SDCL § 21-22-17 requires the account to accompany notice of the hearing. SDCL § 21-22-18 ordinarily serves fiduciaries, beneficiaries, and attorneys of record personally, by prepaid mail to the address in the proceeding, or electronically at least 14 days before the hearing. The court may shorten the period for good cause or approve a different notice form.

The general information provisions are separate. SDCL § 55-2-13 gives qualified beneficiaries specified notice, instrument-copy, and reasonable administration- information rights, subject to the instrument and authorized written directions. Those rights do not themselves create an annual financial report. For a revocable trust, SDCL § 55-2-14 generally directs administration information to the settlor or the settlor's designated agent rather than every beneficiary.

Approval and release require the statutory process

For an unsupervised trust, the 180 days in SDCL § 55-3-45 run after a copy of the accounting is provided in accordance with § 55-2-24. If the distribution beneficiary makes no objection, the beneficiary is deemed to approve the accounting and the trustee is released as to matters set forth in it, except for fraud, intentional misrepresentation, or material omission.

The statute also permits alternative approval by a trust advisor or protector or through statutory representation when information has been waived or modified under § 55-2-13 or the governing instrument authorizes it. Section 55-2-13 itself lets a beneficiary waive its notice or information rights and withdraw the waiver for future reports and information.

For a supervised account, SDCL § 21-22-16 requires any objection in writing by or before the hearing. All beneficiaries can dispense with hearing notice by joining in the report or giving written approval under SDCL § 21-22-21. Final court approval is conclusive under SDCL § 21-22-30 and releases the trustee as to matters stated in the accounting, subject to the same fraud, intentional-misrepresentation, and material- omission exceptions.

Supervised noncompliance carries express consequences

The court examines every supervised report whether or not anyone objects under SDCL §§ 21-22-22 and 21-22-23. It may appoint a disinterested referee, accountant, or investigator at the trust's expense under SDCL § 21-22-24.

SDCL § 21-22-26 makes a noncomplying fiduciary subject to removal, liable for a beneficiary's resulting damages, and subject to compensation forfeiture during the noncompliance period unless the court accepts the statute's inadvertence, reasonable- excuse, and diligent-performance showing. The failure does not invalidate the fiduciary's acts.

What trips people up

• Information rights are not an annual-account statute. Sections 55-2-13 and 55-2-14 address information about administration; the financial-accounting rules are in § 55-3-45 and chapter 21-22.
• The 180-day result needs the prescribed account and notice. Sending an asset list without the transactions, receipts, disbursements, reporting period, and written § 55-3-45 notice does not match the statutory definition.
• The 120-day annual deadline starts with supervision. It is not a statewide deadline for every private trust.
• Silence and court approval are different routes. One is the unsupervised distribution beneficiary's 180-day non-objection; the other follows a supervised hearing and final court approval.

Common questions

Must every South Dakota trustee send an annual accounting?

No. The automatic annual filing rule in § 21-22-14 applies after court supervision has begun. Section 55-3-45 supplies an optional accounting-and-approval route for an unsupervised trust without prescribing annual frequency.

Does every beneficiary receive the unsupervised accounting?

Section 55-3-45 ties its 180-day deemed-approval rule to a distribution beneficiary, meaning an eligible or permissible distributee of income or principal. Other beneficiaries may have different information or representation rights.

Can a supervised account be approved without an objection?

Yes, but the court still examines the filed report and trustee acts under §§ 21-22-22 and 21-22-23. Final approval, not merely the lack of an objection, gives the conclusive effect described in § 21-22-30.
