How Much Does a Will Cost in South Dakota?

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 a will directs an estate through probate rather than avoiding it. 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.

What a will does not do in South Dakota

A will directs an estate through probate; it does not remove assets from it. A will tells the South Dakota probate court who receives what and who administers the estate. Property governed by the will still passes through probate — the court-supervised, public process.

The cost of the document and the cost of probate are therefore separate figures. For what probate itself costs in South Dakota, see How Much Does Probate Cost in South Dakota?.

What passes outside probate in South Dakota

Assets transfer outside probate only by operation of law or contract, regardless of what a will says. The recognised mechanisms are:

Beneficiary designations — retirement accounts, life insurance, and payable-on-death accounts pass to the named beneficiary.
Joint ownership with right of survivorship — passes to the surviving owner.
Transfer-on-death instruments, where South Dakota authorises them.
Assets titled into a funded living trust.

A will has no effect on any asset transferred by these routes. For the South Dakota figures on the trust alternative, see How Much Does a Living Trust Cost in South Dakota?, and for the documented differences between the two instruments, Will vs. Trust: How They Differ.

What affects the price in South Dakota

Published pricing varies with these factors:

Preparation route. Online will services are the lower end of the range; attorney drafting is the upper end. South Dakota-specific forms and a self-proving affidavit are not included by every service.
Bundling. A will, a financial power of attorney, and a healthcare directive are commonly quoted together at less than the sum of their separate prices. The power of attorney and directive operate during life; a will operates only at death.
Estate complexity. Minor children, blended families, business interests, special-needs beneficiaries, and estate-tax exposure are the factors attorneys cite for higher quoted fees.
