Requirements sourced from primary state statutes and verified by First Light's legal data team.

Sign the will in the presence of 2 adult witnesses at the same time. Do not pre-sign the document — your witnesses must watch you sign.

Each witness must then sign the will in your presence and in each other's presence. Witnesses must be adults and should not be named as beneficiaries in your will.

South Dakota does NOT require notarization for a valid will. Witnesses alone are sufficient.

Self-proving affidavit available in South Dakota — strongly recommended. If a notary is present at signing, your witnesses can sign a self-proving affidavit at the same time. This prevents your witnesses from having to testify during probate. Ask your attorney to prepare one.

Note: South Dakota recognizes handwritten (holographic) wills, but a typed and witnessed will like the one First Light generates is significantly stronger.

What to Know

·Your will requires 2 witnesses — notarization is not required.
·A self-proving affidavit is available and strongly recommended — it avoids requiring witnesses in probate.
·If you cannot sign, another person may sign on your behalf in your presence and at your direction.
·Divorce automatically revokes your ex-spouse's bequests and executor appointment. Beneficiary designations on insurance and retirement accounts are not affected — those must be updated separately.
·Marriage does not revoke a prior will. Update your will after marrying to include your spouse.
·Children born after your will are automatically entitled to an intestate share, even if not named.
·A spouse not mentioned in your will is entitled to a minimum share under state law.
·Guardian nominations for minor children in your will carry strong weight with courts.
·Estates under $100,000 may qualify for simplified probate.
·Transfer-on-death deeds are available to pass real estate outside probate.
·Handwritten (holographic) wills are recognized but far less reliable than witnessed wills.

Sign the Power of Attorney before a notary public.

A notary public must be present when you sign. Witnesses are not required in South Dakota.

Tip: South Dakota has an official statutory POA form. First Light's document is structured to be consistent with South Dakota's statutory requirements.

What to Know

·Your POA is durable by default — it survives incapacity without special language.
·Notarization is required. Witnesses are not.
·Springing POAs are permitted — the POA can activate only upon incapacity.
·Some financial powers (like changing beneficiaries or managing trusts) must be explicitly granted — a general POA is not enough.
·For real estate transactions, the POA should be recorded with the county recorder.
·Copies may have limited acceptance — present the original when possible.
·You can nominate a guardian or conservator for yourself in your POA.

Sign the Advance Healthcare Directive in the presence of 2 witnesses.

Witnesses must be adults. Witnesses should not be:

— Your Healthcare Proxy
— A relative by blood or marriage
— An heir or beneficiary
— Your attending physician or healthcare provider
— An employee of a healthcare facility where you are a patient

South Dakota REQUIRES notarization for a valid Healthcare Directive. A notary must be present in addition to your witnesses.

After signing, give a copy to your Healthcare Proxy and your primary care physician. Store the original with your other legal documents — not in a safe deposit box that your proxy cannot access.

What to Know

·Your state uses separate instruments for healthcare agent appointment and living will. Both are needed.
·2 witnesses and notarization are required.
·Limited electronic execution options may exist, but wet-ink originals are strongly recommended.
·Artificial nutrition and hydration decisions are covered by general treatment preferences.
·Your directive may be suspended or limited during pregnancy. Your document should acknowledge this provision.
·A separate HIPAA authorization is recommended so your agent can access your medical records.

What happens if I sign it wrong?

A will or legal document that is not properly executed — missing witnesses, signed in the wrong order, or lacking a required notary — may be declared invalid by a probate court. This means your wishes may not be honored and your estate could be distributed by South Dakota intestacy law.

Some states have a harmless error doctrine that can save a defectively signed will if the court is satisfied the document reflects your true wishes — but this is never guaranteed and always involves litigation.

The safest approach: follow the signing steps above carefully, and consider having an estate attorney present at signing.
