Make a will, living trust & powers of attorney in South Dakota

South Dakota sets its own rules for who can make a will, how it must be signed and witnessed, whether it needs a notary, and how estates are taxed. Estateur drafts your South Dakota will, revocable living trust, and powers of attorney through a guided interview, then validates every document against South Dakota law before you ever see it. It is a self-help document-preparation service, not a law firm.

How to make a valid will in South Dakota

A South Dakota will must be in writing and signed by you in front of two witnesses. Notarization is not required for the will to be valid, but a self-proving affidavit — which is notarized — makes probate easier by removing the need for your witnesses to testify later. South Dakota recognizes handwritten (holographic) wills, but a properly witnessed will is far stronger and easier to probate.

Spousal protection. Augmented-estate sliding scale 3%–50% by marriage length; $50k supplemental (SDCL 29A-2-202). A will can't fully disinherit a surviving spouse in most states — Estateur's interview flags this for you.

Living trusts & avoiding probate in South Dakota

A will still has to pass through South Dakota probate — a public, court-supervised process — before your assets reach your heirs. A revocable living trust holds your assets during life and transfers them at death without probate, which is usually faster and stays private. A trust is not right for everyone; it depends on whether you own real estate, the size and complexity of your estate, and your goals.

Estateur's free quiz recommends whether a will-based or trust-based plan fits your South Dakota situation, and every trust-based plan includes a pour-over will as a companion document.

South Dakota estate planning: common questions

Is an online will legal in South Dakota?
Yes. South Dakota does not care who typed your will — it cares that the will meets South Dakota's execution rules. A will is valid in South Dakota when it is in writing, signed by you, and witnessed by two people (SDCL 29A-2-502). Estateur builds each South Dakota will to those rules and includes step-by-step signing instructions, so an online will you sign correctly is just as valid as one prepared any other way.
How many witnesses does a will need in South Dakota?
South Dakota requires two witnesses to sign your will. Adding a notarized self-proving affidavit is optional but recommended — it lets the will be admitted to probate without tracking down your witnesses. South Dakota also recognizes handwritten (holographic) wills, though a witnessed will is stronger.
Do I need a lawyer to make a will in South Dakota?
No. South Dakota law does not require a lawyer to make a valid will — you can prepare and sign your own. Estateur is a self-help document-preparation service (not a law firm, and no attorney personally reviews each plan) that drafts your South Dakota documents against the state's verified rules and validates them before you see them. For complex situations — large or taxable estates, blended families, special-needs beneficiaries, or business succession — consulting a licensed South Dakota attorney is wise.
Does South Dakota have an estate tax or inheritance tax?
South Dakota has no state estate tax and no state inheritance tax. Only the federal estate tax can apply, and it affects very few estates.
How much does an online will cost in South Dakota?
Estateur uses flat, one-time pricing that is the same in South Dakota as in every other state: a single Last Will & Testament is $79, or the full Will Plan (seven documents) is $99, with no subscription required.
