Overview

Sully County is located in South Dakota with a population of approximately 1,446. The Sixth Judicial Circuit Court handles all probate and estate matters for decedents who were domiciled in the county at the time of death.

South Dakota probate is governed by South Dakota Codified Laws Title 29A (Uniform Probate Code). The process begins with filing a Petition for Informal Probate and Appointment of Personal Representative to admit the will and appoint a personal representative. The court then issues Letters Testamentary for testate estates or Letters of Administration for intestate estates.

South Dakota offers a simplified procedure for small estates. If the value of the entire estate, less liens and encumbrances, does not exceed $100,000, successors may use an Affidavit for Collection of Personal Property after a 30-day waiting period, avoiding full probate.

South Dakota does not have a statutory fee schedule for attorneys or personal representatives; fees must be reasonable based on the services provided.

Filing Process

Step 1: Determine If Probate Is Necessary

Before filing, assess whether formal probate is required:

  • Affidavit for Collection of Personal Property: If the estate is valued at $100,000 or less and 30 days have passed since death, you may be able to collect assets via affidavit without court appointment.
  • Joint Tenancy: Assets held in joint tenancy with right of survivorship pass directly to the surviving owner.
  • Trust administration: Assets held in a living trust generally do not require probate.

Step 2: File the Petition

If formal or informal probate is needed, file a Petition for Informal Probate and Appointment of Personal Representative with the Sixth Judicial Circuit Court. Include:

  • Original Will (if applicable)
  • Certified death certificate
  • Statement of Informal Probate (or similar acceptance of appointment)
  • Filing fee ($75.00)
  • Any additional required documents (e.g., Renunciations, Bond if required)

South Dakota utilizes an electronic filing system (Odyssey File & Serve) for attorneys, though pro se litigants may often file in paper.

Step 3: Provide Notice

After filing, you must:

  • Mail notice of the probate and appointment to all heirs, devisees, and interested parties within 30 days of appointment.
  • Publish notice to creditors in a legal newspaper in Sully County (such as the Onida Watchman) once a week for three successive weeks.

Step 4: Attend the Hearing

For informal probate, a hearing is typically not required if the paperwork is in order. The Clerk or Registrar can issue the Letters. For formal probate (contested or complex cases), a hearing will be scheduled before a judge.

Step 5: Administer the Estate

After receiving Letters, the personal representative must:

  • Allow the creditor claim period to expire (4 months after first publication)
  • Inventory and appraise all estate assets within 3 months of appointment
  • Pay valid creditor claims and estate expenses
  • File federal and state tax returns as needed
  • Distribute assets to beneficiaries
  • Close the estate by filing a Verified Statement of Personal Representative Closing Estate
