Office: 210 West Grant StreetSpearfish, SD 57783
Phone: (605) 717-2020

Estate planning attorneys in South Dakota average $311 an hour for wills and estates work. A flat-fee package runs $933 to $1,866 for a simple individual will and $3,580 to $5,370 for a basic revocable trust. An online service prices the same documents in the tens to low hundreds of dollars; the South Dakota will cost calculator sets the two side by side.

In South Dakota, estates valued at $100,000 or less skip probate with the Small Estate Affidavit, 30 days after death. That route is a form rather than a court case, and most families handle it without an attorney. Above the line, formal probate generally benefits from counsel for the procedural work, even when nothing is contested. The South Dakota probate calculator estimates the cost by estate value.

In South Dakota, the situations where counsel is typically worth the cost are: a blended family with children from a prior relationship; a business, rental property or significant investment assets; a dependent with special needs, who needs a special-needs trust to keep benefits; substantial property in more than one state. Where none of these apply, an online or self-help document is often enough.

South Dakota splits the two: probate attorney fees of typically 1.8% to 2.8% of the estate, but the executor's compensation follows a statutory schedule, about $12,585 on a $500,000 estate. That makes the executor's share predictable, which helps when a family member serves and is unsure what to charge.

Filter the directory by county and by the practice area you need, and look for experience with your situation; a board certification in estate planning, trust or probate law is a strong signal. Most South Dakota estate planning attorneys offer an initial consultation, some free and some for a flat fee. Ask up front whether the firm bills by the hour or by package, and what your situation is expected to cost.

Trust Litigation Attorneys in South Dakota

South Dakota attorneys average $311 an hour for wills and estates work. A basic will from an attorney runs $933–$1,866; online services cost $30–$300.

South Dakota sets executor compensation by statute — about $12,585 on a $500,000 estate, roughly 2.5%, even though the attorney's fee isn't fixed. That's the predictable cost component on probate here.

Worth knowing: estates under $100,000 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.
