How Much Does a Will Cost in South Dakota?

Published June 11, 2026 7 min read

Quick answer

A simple will in South Dakota typically costs $250 to $900 with an attorney, and $0 to $150 online (some tools are free). South Dakota is one of the states that DOES recognize handwritten (holographic) wills, so a will can technically cost nothing — but the honest point is that a will doesn't avoid probate. It directs your estate through South Dakota probate, it doesn't skip it. If avoiding probate is the goal, that's a living-trust question.

A simple will in South Dakota is genuinely inexpensive — $250 to $900 with an attorney, and as little as $0 online. The price is low for a reason: a will is a relatively simple document. The cost climbs only when your situation is complicated — minor children and a guardianship decision, a blended family, a business, or potential estate tax.

What makes a will valid in South Dakota

A non-holographic South Dakota will must be in writing, signed by the testator (or in the testator's name at the testator's direction), and signed by at least two witnesses who witnessed the signing or the testator's acknowledgment (SDCL 29A-2-502).

The witnesses should be disinterested — that is, not people who inherit under the will — so no one can later argue they had a reason to lie about the signing. Get that one detail wrong and the gift to an interested witness (or the whole will) can be challenged.

Can you write your own will by hand in South Dakota?

South Dakota DOES recognize holographic (handwritten) wills — a will is valid whether or not witnessed if the signature and the material portions are in the testator's own handwriting (SDCL 29A-2-502). They're legal but easier to contest and harder to probate than a witnessed will.

Even where a handwritten will is legal, it’s the riskiest way to do it: no witnesses means no one to confirm it was really you and that you weren’t pressured, and ambiguous handwriting is a gift to anyone who wants to contest it. A typed, witnessed, self-proved will costs very little and avoids all of that.

The self-proving affidavit (a small step that saves a big headache)

South Dakota allows a self-proving will via an affidavit signed by the testator and witnesses before a notary (SDCL 29A-2-504), letting the court admit the will without the witnesses testifying — which speeds up probate.

Without it, your witnesses may have to be tracked down years later to confirm they watched you sign — which can be impossible if they’ve moved, lost touch, or died. It’s one of the cheapest, highest-value things you can add to a will.

The catch: a will doesn’t avoid probate in South Dakota

This is the part the price tag hides. A will is cheap because of what it doesn’t do: it does not avoid probate. A will simply tells the South Dakota probate court who should get what and who should run the estate. Everything it covers still goes through probate — the public, months-long, fee-charging court process.

So the real cost of “just a will” isn’t the $0–$1,000 you pay now; it’s the probate your family pays later. To see that number for South Dakota, read How Much Does Probate Cost in South Dakota?.

Do you need more than a will in South Dakota?

For a lot of people, a will is genuinely enough — especially renters, younger families, and anyone whose main assets (retirement accounts, life insurance) already pass by beneficiary designation outside probate.

You may want more than a will if you own a home and want to spare your family probate, value privacy, own property in more than one state, or want a plan for incapacity. That’s where a living trust comes in — it costs more up front but can avoid probate entirely. Compare the two honestly:

How to keep the cost down in South Dakota

Use a quality online service for a truly simple estate. Several are free; paid ones run $0–$150. Make sure it’s South Dakota-specific and includes a self-proving affidavit.
Bundle the basics. A will, a financial power of attorney, and a healthcare directive are cheaper together than separately — and the POA and directive matter while you’re alive, which a will never does.
Pay for an attorney when it’s not simple. Minor children, a blended family, a business, a special-needs beneficiary, or estate-tax exposure are all worth a real attorney’s time. A cheap will that’s invalid or unclear is the most expensive kind.

The honest takeaway

A will in South Dakota costs $250 to $900 with an attorney, or nearly nothing online — and for many people that’s all they need. Just go in clear-eyed about what you’re buying: a will directs your estate through probate; it doesn’t avoid it. If avoiding probate matters to you, price a living trust against what South Dakota probate would actually cost your family, and decide from there.

Whatever you choose, sign it correctly with two disinterested witnesses, add the self-proving affidavit where South Dakota allows it, and tell your executor where to find it.
