Before you begin — know the assets and liabilities

Before you file anything in Cass County, identify what the decedent owned, what passed outside probate, what debts are known and whether any real estate is in Cass County. That asset picture determines whether the family is dealing with a full administration, a small estate affidavit, a refusal of letters or another Missouri route.

Sunset's estate settlement process starts with asset discovery across more than 2,300 financial institutions, then uses that information to help prepare the right packet for the Harrisonville counter or for a Missouri probate attorney to review.

Which court handles jurisdiction

The Probate Division of the Circuit Court of Cass County serves estates for decedents domiciled in Cass County. That includes communities such as Harrisonville, Belton, Raymore, Peculiar, Pleasant Hill, Garden City and other Cass County communities.

Cass County is in the 17th Judicial Circuit with Johnson County, and Missouri is divided into forty-six judicial circuits (RSMo 478.011). A shared circuit is not a shared courthouse. Cass County estates are filed at the Cass County Justice Center in Harrisonville, not at the Johnson County courthouse in Warrensburg.

Missouri venue for probating a will and granting letters is the county where the decedent was domiciled (RSMo 473.010). In Cass County the probate docket is Division IV of the 17th Judicial Circuit.

The jurisdiction process

  1. Build the asset and debt list first. Separate probate assets from accounts, deeds or beneficiary designations that may pass outside the estate, and note whether any Cass County real estate is involved.
  2. Choose the Missouri route. A full administration appoints a personal representative. A small estate affidavit (RSMo 473.097) or refusal of letters (RSMo 473.090) appoints no personal representative, which matters because a non-lawyer personal representative cannot appear in court except through an attorney (RSMo 473.153.7).
  3. Get the forms. Cass County accepts the Jackson County probate forms if the caption is changed to Cass County. Add the required Missouri filing information sheet, and use the property listing exhibit when the application requires one.
  4. Deliver the original will to the probate division. The original will goes to the Probate Division in Harrisonville even when other papers are filed electronically by an attorney. Filing the will by itself carries no charge under the Cass County probate schedule revised October 14, 2025.
  5. File with the clerk of the probate division. Use the Circuit Clerk's office on the first floor of the Cass County Justice Center, 2501 W. Mechanic, Harrisonville, or mail the packet to that address. The clerk cannot accept a new case without the completed filing information sheet (Local Rule 4.3).
  6. Check redactions and disclosures before filing. In probate cases, Local Rule 72.1 makes the filer responsible for redacting account numbers, identification numbers and other confidential information. Local Rule 3.3 requires any person who used a generative AI tool to research or draft a filing to tell the court which tool was used and how.
  7. Pay the Cass County court cost. The counter accepts cash, a credit card or a money order payable to the Cass County Circuit Clerk for court costs, while attorneys pay through the electronic system.
  8. Handle notice and publication. When letters issue, the clerk causes notice to creditors to be published once a week for four consecutive weeks (RSMo 473.033). The Probate Division's schedule names Cass County newspapers for publication, and the newspaper charge is separate from the court cost.
  9. Follow the hearing notice, receive letters and complete the estate settlement. The court sets any hearing, and the notice of hearing controls whether it is in person or virtual. If you go to the Justice Center, check the closings line in bad weather and plan for the electronic-device rule. After letters issue, the personal representative administers the estate, files required inventory and settlement papers, and completes the estate settlement.

Forms and documents

Probate forms in Cass County

Cass County does not maintain a separate Cass County probate packet. Instead, the Probate Division accepts the Jackson County probate forms if the heading is changed to Cass County. The Missouri Judiciary also maintains statewide probate forms, and Cass County's local rule requires the filing information sheet when a new case is opened.

Form or packetHow it is used in Cass County

Checklists for new estatesUse the checklist for the route you are filing, such as testate, intestate, abbreviated matters or determination of heirship.

Redaction formsUse the redaction forms when confidential information must be protected, because Local Rule 72.1 makes redaction the filer's responsibility.

Fees

Cass County has its own Probate Division cost schedule, revised October 14, 2025.

Local nuance

Cass County-specific considerations

Local pointWhat it means in Cass County
Probate docketThe probate docket is Division IV of the 17th Judicial Circuit. The estate is filed in Harrisonville even though Cass County shares the circuit with Johnson County.
Public access to probate case papersLocal Rule 72.1 keeps inventories, annual and final settlements, statements of account, account statements, vouchers, verifications, agreements of depositories, birth certificates, death certificates and case information filing sheets from public access. They are not produced to anyone other than parties or counsel of record without a court order.
Redaction is the filer's jobLocal Rule 72.1 makes the filer responsible for removing confidential information such as account numbers and identification numbers before filing. Court personnel do not screen each filing for that issue.
Generative AI disclosureLocal Rule 3.3 requires any person who used a generative AI tool to conduct legal research referenced in a pleading or to draft a filing to disclose the tool and how it was used.
Electronic devicesLocal Rule 11.1 prohibits cell phones, laptops, tablets, cameras and recording devices inside the Cass County Justice Center, except for the categories the rule names. Plan before you go to the first-floor counter.
E-filing exceptionLocal Rule 4.10 requires electronic filing where implemented but excepts non-lawyer self-represented litigants. Attorneys file electronically.
Filing information sheetLocal Rule 4.3 requires the JIS party information sheet when a new case is opened, and the clerk cannot accept a new case without it.
Format of filingsLocal Rule 3.2 sets formatting requirements, including one-sided 8.5 by 11 inch pages, one inch margins, page numbers and enough copies for required service.
Recorder of deedsWhen a small-estate certificate or refusal order must be recorded for Cass County real estate, the Recorder of Deeds is at 102 E. Wall Street in Harrisonville, a different building from the Justice Center.

Scenarios

ScenarioLocal pathWhere Sunset helps
Surviving spouse with co-owned homeStart with whether the home is even in the probate estate. If a refusal of letters fits, Cass County's probate schedule revised October 14, 2025 lists a $53.50 cost for refusal to grant letters. The spouse route is based on Missouri exempt property and the support allowance, not a fixed dollar cap (RSMo 473.090). Cass County accepts the Jackson County surviving-spouse form if the heading is changed to Cass County, and the statewide form is PR 33 with PR 22 Exhibit A for the property listing. If the order affects Cass County real estate, take a certified copy to the Recorder of Deeds at 102 E. Wall Street.Sunset identifies accounts and assets before the spouse chooses a route, prepares the Cass County packet and helps decide when a vetted Missouri probate attorney should review the plan.
Out-of-state adult child with small estateThe Circuit Clerk's office on the first floor of the Justice Center can receive a mailed packet at 2501 W. Mechanic, Harrisonville. Under Cass County's probate schedule revised October 14, 2025, a small estate costs $53.50, or $88.50 if a will is admitted with it, and publication is required when the value listed in the affidavit is more than $15,000 (RSMo 473.097). Include the filing information sheet, because Local Rule 4.3 says the clerk cannot accept a new case without it. The original will must reach the probate division on paper, and filing the will by itself carries no charge.Sunset helps the adult child find accounts without traveling first, generate the affidavit packet, track what must be mailed to Harrisonville and connect with counsel if the matter no longer fits a no-letters route.
Parent settling predeceased child's estate, home must be soldA sale usually points toward a full administration. Cass County's probate schedule revised October 14, 2025 lists $133.50 for letters of administration without a will and $168.50 for letters testamentary with the will admitted, plus a final-inventory charge once the inventory reaches the listed bands and a $30.00 annual charge for each year the estate remains open. Missouri also limits court appearances by a non-lawyer personal representative (RSMo 473.153.7), so counsel is usually involved when a house sale, hearing or dispute is part of the estate settlement. Keep vouchers and account statements, because settlement papers are built from them and are kept from public access in this circuit under Local Rule 72.1.Sunset assembles the asset picture, generates the starting packet, and connects the parent with a vetted local probate attorney for the court appearance, sale and estate settlement steps.

When to hire an attorney

In Missouri a personal representative who is not a lawyer cannot appear in court except through an attorney, although the personal representative may prepare and file their own inventories and settlements (RSMo 473.153.7). Counsel makes practical sense in a Cass County full administration when real estate must be sold, an heir objects, a creditor claim is disputed, a hearing is likely or the proposed personal representative lives outside Missouri. A small estate affidavit (RSMo 473.097) or refusal of letters (RSMo 473.090) appoints no personal representative, and the 17th Judicial Circuit's electronic filing rule expects non-lawyer self-represented filers at the counter. Sunset connects families to a vetted local probate attorney.

How Sunset helps

Find the accounts and assets. Sunset searches across more than 2,300 financial institutions to help families identify accounts, balances and possible nonprobate transfers before choosing a Missouri route. That asset map is the foundation of a clean estate settlement.

Generate the probate packet. Sunset uses the estate information to assemble the forms and supporting documents for the Cass County Probate Division, including the local instruction to change accepted Jackson County form headings to Cass County.

Find a local probate attorney. When a full administration, real estate sale, dispute or court appearance calls for counsel, Sunset connects the family with a vetted Missouri probate attorney who can handle the Harrisonville filing and appearance.

Sunset is free for families. Families can use Sunset to organize the estate, prepare for the Cass County counter and move the estate settlement forward without paying Sunset a fee.

Frequently asked questions

Where do I file to probate a will in Cass County?

File with the clerk of the Probate Division of the Circuit Court of Cass County at the Cass County Justice Center, 1st Floor, 2501 W. Mechanic, Harrisonville, MO 64701. The original will goes to the probate division in Harrisonville, and filing the will by itself carries no charge under the Cass County probate schedule revised October 14, 2025.

Cass County shares a judicial circuit with Johnson County. Do I have to go to Warrensburg?

No. Cass County is in the 17th Judicial Circuit with Johnson County, but a Cass County estate is filed at the Cass County Justice Center in Harrisonville. Missouri venue for letters is the county where the decedent was domiciled (RSMo 473.010).

When is the Cass County Circuit Clerk's office open, and does it close for lunch?

The office is open Monday through Friday, 8:00 a.m. to 4:30 p.m., including during the lunch hour. The court also lists an Inclement Weather and Other Closings Line at (816) 380-8511.

What does it cost to open an estate in Cass County?

Under the Cass County probate schedule revised October 14, 2025, letters of administration cost $133.50, letters testamentary with the will admitted cost $168.50, a small estate costs $53.50, a small estate with the will admitted costs $88.50, refusal to grant letters costs $53.50 and determination of heirship costs $53.50. A small estate over $15,000 must be published (RSMo 473.097). Full estates can also have a final-inventory charge and a $30.00 annual charge for each year the estate remains open under the same schedule.

Does Cass County have its own probate forms?

Cass County does not maintain a separate Cass County probate packet. The Probate Division accepts the Jackson County probate forms if the heading is changed to Cass County. The statewide Missouri filing information sheet is also required for a new case under Local Rule 4.3.

Can I file a Cass County probate case myself, or do I have to e-file?

Attorneys file through the Missouri eFiling System. In the 17th Judicial Circuit, Local Rule 4.10 excepts non-lawyer self-represented filers from electronic filing, so a self-represented probate filer can work with the Harrisonville counter in person or by mail. In a full administration, a non-lawyer personal representative cannot appear in court except through an attorney (RSMo 473.153.7).

Can I look up a Cass County estate case online, and can I read the inventory?

You can look up Cass County probate dockets on Case.net. The docket is public, but Local Rule 72.1 keeps inventories, annual and final settlements, statements of account, vouchers and death certificates from public access. Those documents go to parties or counsel of record unless a judge orders otherwise.

Will I have to appear in person in Harrisonville?

The court sets the hearing and the notice of hearing controls. Some Missouri hearings can use the Judiciary's Virtual Hearing Room, but not all cases are eligible. If a virtual hearing is set, the notice will say so. A non-lawyer personal representative cannot appear in court except through an attorney (RSMo 473.153.7).

Can I bring my phone into the Cass County Justice Center?

Local Rule 11.1 prohibits cell phones, laptops, tablets, cameras and recording devices inside the Cass County Justice Center, except for the categories the rule names. Plan before you travel to the first-floor counter.

Do I need a lawyer for a Cass County estate?

For a full administration, Missouri law prevents a non-lawyer personal representative from appearing in court except through an attorney (RSMo 473.153.7). A small estate affidavit (RSMo 473.097) or refusal of letters (RSMo 473.090) appoints no personal representative, so that restriction does not apply to those no-letters routes.
