S.D. Codified Laws § 55-4-37
If permitted by the trust instrument or will under which a fiduciary serves, or by order of a court having jurisdiction of the estate or trust, a fiduciary may enter into a partnership agreement or arrangement with others or accept the assignment of, or otherwise acquire, hold, and dispose, of an interest in a partnership, and in so doing may become either a general or a limited partner. If the fiduciary becomes a partner, as to creditors of, or claimants against, the partnership and as to the other members of the partnership, the liability, if any, of the fiduciary for the debts and other liabilities of the partnership, whether arising under contract, tort, or otherwise, are limited to the assets of the trust or estate, or so much thereof as may be necessary to discharge such debts and liabilities.
