Hiring a Special Needs Planning Attorney in South Dakota

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.

South Dakota has an unusual fee split: attorney fees are negotiable, but the executor's compensation is set by statute at 2.5%–5% of the estate valueSDCL § 29A-3-719(c) (5% on first $1K, 4% on $1K-$5K, 2.5% on amounts over $5K for personal property; real property court-determined as just and reasonable)Verified May 27, 2026. That makes the executor portion predictable, which is useful when a family member is serving as executor and isn't sure what to charge.

Start by filtering the directory above by your county and the practice area you need. Look for firms with experience in your specific situation — board certifications in estate planning, trust, or probate law are a strong signal. Most South Dakota estate planning attorneys offer an initial consultation; some are free, others charge a flat fee. Ask up front whether the firm bills by the hour or by flat-fee package, and what the expected cost is for your situation.

South Dakota sets the executor's fee by statute even though the attorney's isn't. The executor takes 2.5%SDCL § 29A-3-719(c) (5% on first $1K, 4% on $1K-$5K, 2.5% on amounts over $5K for personal property; real property court-determined as just and reasonable)Verified May 27, 2026–5%SDCL § 29A-3-719(c) (5% on first $1K, 4% on $1K-$5K, 2.5% on amounts over $5K for personal property; real property court-determined as just and reasonable)Verified May 27, 2026 of the estate as a fixed percentage. That's the predictable cost component on probate here.

Worth knowing: estates under $100,000§ 29A-3-1201Verified May 27, 2026 can use South Dakota's simplified affidavit instead of formal probate. If your situation is straightforward and the estate fits, you may not need an attorney at all.
