Petition to Probate a Will Requirements in South Dakota

At a glance

Requirements one by one

Governing law and proceeding type

South Dakota provides two ordinary routes. Section 29A-3-301 makes informal probate a verified application to the circuit-court clerk, with or without an informal-appointment application. Section 29A-3-401 makes formal testacy a court proceeding begun by an interested person's petition for an order after notice and hearing. A formal petition may seek probate without seeking appointment.

Under §§ 29A-3-102 to -103, the will needs a probate order to transfer property or nominate a personal representative, and the representative needs appointment, qualification, and letters before administration begins.

Court and venue

Section 29A-1-201 defines the court as the circuit court. Section 29A-3-201 places the first proceeding in the decedent's domicile county or, for a nondomiciliary, any county containing the decedent's property. Section 29A-1-303 gives the first proper court the exclusive right to proceed unless it transfers venue.

Who may petition

Both routes require an interested person. The § 29A-1-201 definition includes heirs, devisees, children, spouses, creditors, beneficiaries, persons with an estate claim or property right, persons with appointment priority, and fiduciaries representing interested persons. The definition remains tied to the purpose and matter involved in the particular proceeding.

Petition contents

Section 29A-3-301 requires verification and a detailed informal filing. It includes the applicant's interest; the decedent's identity, birthdate, death, and domicile; heirs and devisees and minor ages; nondomiciliary venue; existing representatives; notice demands; timeliness; the original or certified-copy status; execution and revocation beliefs; and, when appointment is requested, the nominee's name, address, and priority.

Section 29A-3-402 carries those facts into formal probate and adds a request to determine heirs and testacy plus a statement about the original will. A formal appointment issue may also use § 29A-3-414 when priority or qualification must be resolved.

Original will, copy, and lodging

For informal probate, §§ 29A-3-301 and 29A-3-303 require the original to be with the court or accompany the application, unless a certified copy of a will probated elsewhere accompanies it. For formal probate, § 29A-3-402 requires the petition to say whether the original is with the court or accompanies the petition.

If the formal route lacks an original or authenticated prior-probate copy, the petition states the will's contents and why it is unavailable. A copy plus at least one credible witness can prove contents if the court is reasonably satisfied the will was not revoked. With no copy, clear and convincing proof is required.

Filing or production deadline

Section 29A-3-108 generally bars ordinary informal probate, formal testacy, and appointment proceedings more than three years after death, while listing specific late routes. Section 29A-2-516 separately requires the custodian, after an interested person's request, to deliver the will with reasonable promptness to the court or someone able to secure probate. The custodian rule has no fixed number of days.

Proof and self-proving route

In informal probate, §§ 29A-3-302 to -303 permit admission after 120 hours and without further proof when the apparent signatures and attestation clause show statutory execution. The clerk may otherwise rely on the will's appearance or a sworn statement or affidavit from a person who knows the execution circumstances.

In an unopposed formal case, § 29A-3-405 allows the court to act on the pleadings or hold an open-court hearing. If execution evidence is needed, one attesting witness's affidavit or testimony, including self-proof, is sufficient; other evidence is available when witness proof is not. In a contested non-self-proved case, § 29A-3-406 ordinarily requires at least one competent, available in-state attesting witness when execution evidence is necessary.

Notice, hearing, and objections

Informal probate is the limited-notice route. Under § 29A-3-306, notice of the application goes only to a notice demandant and any existing personal representative. If no appointed representative must provide the information, the applicant then has 14 days after informal probate to send heirs and devisees the probate information and a will copy. Informal appointment separately requires advance notice to unwaived equal- or higher-priority persons under § 29A-3-310.

Formal testacy requires a hearing. Sections 29A-3-403 to -404 require notice to heirs, devisees, persons named as representative in relevant wills, the existing representative, and demandants, plus publication for unknown persons or addresses. Under § 29A-1-401, the general rule is 14-day mailing or personal-delivery notice and three weekly publications for unknown persons. An opponent must state the probate objections in the pleadings.

Executor qualification, bond, and letters

Section 29A-3-203 gives first priority to the person selected by a probated will. The nominee must be at least 18, not found unsuitable in a formal proceeding, and, for a bank or trust company, authorized to exercise trust powers in South Dakota.

Before letters, § 29A-3-601 requires an acceptance of office and any required bond. Current § 29A-3-603 says bond is unnecessary unless the court concludes it is in the estate's best interests.

What trips people up

• Application and petition are different routes. The informal application goes to the clerk and carries limited notice. The formal petition goes to the court and requires notice and a hearing.
• Reasonable-promptness delivery is not the three-year probate limit. The custodian's duty arises on an interested person's request. The separate ultimate-limit statute controls when ordinary proceedings may begin.
• The bond statute changed. Current § 29A-3-603 uses a court-best-interests test. Older material referring to a bond demand under § 29A-3-605 is stale; that section is reserved.

Common questions

Must an informal applicant notify every heir before probate?

No. Section 29A-3-306 limits pre-probate notice to a demandant and an existing personal representative. If no appointed representative has the information duty, the applicant sends the probate information and will copy to heirs and devisees within 14 days after admission.

Can a lost will use informal probate?

The cited informal route requires an original with the court or application, or a certified prior-probate copy. Section 29A-3-402 instead supplies the formal lost, destroyed, or otherwise unavailable-will route and its proof standards.

Does a formal case always require live witness testimony?

No. In an unopposed case, § 29A-3-405 permits an order on the pleadings or proof by affidavit. The available in-state attesting-witness requirement in § 29A-3-406 applies when execution evidence is necessary in a contested, non-self-proved case.
