Even if you create a revocable trust in South Dakota, you generally still need a will — most commonly a "pour-over" will that captures any assets you forgot to retitle into the trust. South Dakota also allows transfer-on-death deeds for real estate, which can move property out of probate without a trust. Whether a trust adds enough value over a will-only plan depends on your situation: real property, blended families, and out-of-state assets are the most common reasons. The trust-or-will tool walks through the decision.
Estate planning attorneys in South Dakota average $311 per hourClio Legal Trends Report 2025Verified Jan 1, 2025 for wills and estates work. Flat-fee packages run roughly $933–$1,866 for a simple individual will and $3,580–$5,370 for a basic revocable trust. Online and DIY services cost $30–$300 for the same documents — see the will cost calculator for a side-by-side comparison.
South Dakota has a generous small-estate threshold of $100,000. Estates under that line can use the Small Estate Affidavit procedure, which is a form rather than a court case — most families can handle it without an attorney. For estates above the threshold, formal probate generally benefits from counsel because of the procedural overhead, even when nothing is contested. The South Dakota probate calculator estimates total costs based on estate value.
In South Dakota, the situations where retaining counsel is typically worth the cost are: blended families with children from prior relationships; ownership of a business, rental property, or significant investment assets; special-needs dependents who need a special-needs trust to preserve benefits; substantial property held in multiple states. If none of these describe your situation, the simpler online and DIY tools are often enough.
