South Dakota trust: how it works and how to set one up
A South Dakota trust is a trust under the state's statutes, which allow directed trusts and leave the common-law rule against perpetuities out of force. A qualified disposition needs a qualified trustee in the state. We coordinate checks and the local partner with your lawyer.

What a trust in South Dakota is
A trust starts when a settlor transfers assets to a trustee, who then holds them for the beneficiaries named or described in the trust instrument. South Dakota law frames the instrument and the trustee’s duties.
Title 55 of the South Dakota Codified Laws covers trusts. Chapter 55-1B sets out the directed trust, in which a trust advisor or trust protector holds defined powers beside the trustee.
Chapter 55-16 covers qualified dispositions, the route for a settlor who is also a beneficiary. It sets time limits and a standard of proof for creditor claims.
The common-law rule against perpetuities is not in force in the state, which is why people draft a South Dakota dynasty trust to run across generations.
A qualified disposition needs an irrevocable instrument, so a revocable living trust works differently; the law page shows what a qualified disposition allows.
Plenty of dynasty trusts are discretionary: the trustee decides who receives what and when, guided by the instrument and a letter of wishes the settlor prepares.
Think of the letter as advice the trustee weighs but need not follow. A current letter is the simplest record of what you intend.
Treat each feature as a drafting tool that your lawyer tests against your circumstances. This page does not say any of them will succeed for you.
Who a South Dakota trust suits
It tends to suit settlors living outside the United States who want a US-law trust with a named adviser or protector, as well as families who own a business or assets in the United States.
Examples include:
- Families planning a trust that runs across several generations.
- Business founders who want family company shares held under a directed trust.
- Owners of several trusts who are weighing a private trust company.
- Advisers comparing US states for a client.
Check the trustee first. A trust that relies on chapter 55-16 needs a qualified person as trustee, and the definition is narrow.
Check the federal layer as well. Even a settlor who is not a US person meets US federal rules, such as estate tax filing duties for assets located in the United States.
Your own tax adviser explains how they apply to you; the tax and reporting page gives the source. If you are a US person, tell us at the start, because the checks we run are different.
A trust does not answer every aim. After a first review you may find that a will, a company or another state is the better fit.
What the trustee does
The trustee owns the assets in law and manages them under the instrument. Its job includes accounts, distribution decisions and a written record of every decision.
For a qualified disposition, the trustee must be a qualified person.
The statute lists an individual who truly resides in the state, a trust company organised under state or federal law with its principal place of business in the state, or an insured trust bank in the state.
A local partner takes that trustee role, usually a South Dakota trust company. We coordinate the papers and reporting, and the trustee decides under the deed. Our part is to run the identity checks, collect the documents and prepare the structure with your lawyer.
Decisions as trustee and the formal records rest with the partner. The split is useful when circumstances shift, such as a distribution or the arrival of a new beneficiary.
In a directed trust, a trust advisor or protector holds defined powers. The trustee then follows valid directions within the limits that the instrument and the statute set.
Within the limits the instrument sets, investment advice may come from the settlor or from a manager the settlor names. Your lawyer confirms any role we take, such as protector, before it is written into the instrument.
We suggest reviewing the trust yearly, and again if your family or your assets change.
Documents and steps to start
The set-up steps come in a fixed order, and no signature is given until your lawyer has read the instrument. The sequence is:
- Enquiry, then client acceptance and identity checks.
- Design of the structure with your lawyer, including any holding company.
- Drafting of the trust instrument and your letter of wishes.
- Signing and acceptance by the trustee.
- Transfer of assets to the trustee or to a company the trust owns.
We begin by asking for identity documents, details of the settlor and beneficiaries, the source of the assets and a draft structure.
Later timing is in third-party hands: the trustee’s checks, your lawyers’ drafting, and the banks that open accounts and move assets. We give dates only once your documents have been reviewed.
For documents and the order of steps, read the step-by-step guide. Cost follows the shape of the structure; the cost guide explains the drivers.
We publish the set-up fee for a standard trust; annual administration, event-based work and third-party charges are quoted after we review your case.
Tax attaches to people, not only to the trust. For questions to put to your adviser see tax and reporting, and for quick replies the plain answers.
For planning against claims more generally, read our page on wealth structuring and asset protection.

Frequently asked questions
Who can set up a trust in South Dakota?
A settlor does not have to live in the state. Anyone with assets to place in trust can be the settlor, subject to the identity checks the trustee runs. What matters most is how your home country and US federal rules treat the trust, so your lawyer and tax adviser confirm it suits you first.
How do I start in South Dakota?
Write down who should benefit, what you plan to transfer and who advises you. Then send us a short message with your country of residence. We reply with a document list and a quote, and we line up the local partner who acts as qualified trustee.
Who can help me start in South Dakota?
You need a lawyer of your own, a qualified trustee in the state and a tax adviser at home. We coordinate the checks and papers between them. Legal advice stays with your lawyer, and trustee decisions stay with the trustee.
What is a qualified trustee in South Dakota?
For a qualified disposition, the trustee must be a qualified person: a state-resident individual, a trust company in the state, or an insured trust bank in the state. The transferor cannot be that person. Your lawyer checks the definition against your plan before you sign.
Is a South Dakota trust only for US citizens?
No. A settlor outside the United States can use a trust governed by the law of the state. US federal rules still apply to US-situated assets and to US persons, so your tax adviser explains how they apply to you. Tell us at the start if you are a US person.
