Cass County Probate Division IV
Probate in Cass County is handled by Probate Division IV of the 17th Circuit Court of Cass County, Missouri. It is not a separate courthouse or a standalone county probate office. The probate fee schedule uses the heading "In the 17th Circuit Court of Cass County, Missouri, Probate Division IV," which matches the Missouri circuit-court structure described in the research. The Circuit Clerk is the court-record custodian for probate case records, copies, and public access routing.
Probate records can include decedent estates, wills admitted to probate, will-only filings, letters of administration, letters testamentary, small estates, refusals of letters, determinations of heirship, ancillary estates, trust registrations, successor trustee matters, accountings, guardianships, conservatorships, inventories, annual fees, certified mail, copy requests, and certifications. Some probate records are public through Case.net. Others may require clerk contact because they are older, document-limited, or restricted.
The Cass County Probate page is the local source for the Probate Division form instructions.
That source is especially important because it explains the county-specific form heading rule for probate filings.
Cass County Probate Terms
Probate language can be dense, so the main terms should be read in the context of the Cass County Probate Division's case types. A probate docket may show short entries for orders, letters, inventories, publication, certified mail, guardian ad litem deposits, and accountings. The terms below describe the role or case type, not the final outcome of a specific estate.
- Testator
- A person who made a will before death.
- Executor
- The person named in a will to carry out estate duties, often linked to letters testamentary.
- Intestate
- A decedent estate where the person died without a valid will controlling administration.
- Guardianship
- A probate case about personal care and legal authority for an adult or minor who needs a guardian.
- Conservatorship
- A probate case about management of money or property for an adult or minor who needs a conservator.
- Guardian ad litem
- A court-appointed person who represents the interests of a protected person or minor in the proceeding.
Search Cass County Probate Records
Public Cass County probate records are searched first through Missouri Case.net when a case is available for public remote access. The search path is the same statewide system used for other circuit case types. Select Cass County, 17th Judicial Circuit where the interface allows local narrowing. Search by a party name, estate name, or known case number. Once the case opens, review the docket, party names, case type, hearing entries, orders, and status.
- Open Case.net and choose a name search or case-number search.
- Select Cass County, 17th Judicial Circuit when narrowing by court location is available.
- Search using the decedent, petitioner, ward, protected person, estate, trust, or case number.
- Review the public docket for filings, orders, hearing dates, inventories, letters, and status entries.
- Contact the Circuit Clerk or probate clerk for certified copies, non-public documents, or items that do not display remotely.
Remote search has limits. Case.net may show the existence of a probate case and its docket activity, but certified letters, sealed documents, medical material, minor guardianship details, and sensitive financial filings may be limited or unavailable online. Copy requests can be routed through Cass.Copies@courts.mo.gov or the Circuit Clerk at 816-380-8227 when the case can be identified.
Cass County Probate Court Contact
There is one local probate venue identified in the research: Probate Division IV within the Cass County Circuit Court. The same Justice Center address used for Circuit Court and Circuit Clerk access applies to probate case access. Forms, fees, filings, copies, and public docket questions should be tied to the 17th Judicial Circuit, not to the Recorder of Deeds or a municipal division.
Probate Division IV of the Circuit Court
Cass County Justice Center
2501 W. Mechanic Street
Harrisonville, MO 64701
816-380-8227
Monday-Friday, 8 a.m.-4:30 p.m.
The Justice Center also houses the Circuit Clerk, courts, prosecutor, sheriff, juvenile, and public administrator functions. For probate records, the important distinction is that marriage licenses and land records stay at the historic courthouse Recorder of Deeds, while probate case records remain with the Circuit Court system.
Cass County Probate Forms
The Cass County Probate page gives a specific form instruction: Cass County accepts Jackson County Probate Forms from the 16th Circuit forms page, but users must change the heading to reflect Cass County instead of Jackson County. That detail is easy to miss. A form with the wrong county heading may cause avoidable filing delay, even when the body of the form is otherwise the accepted Missouri probate form.
Common probate filings may include estate petitions, small estate documents, refusal to grant letters, heirship requests, trust filings, guardianship or conservatorship petitions, annual reporting, inventories, and accounting documents. The form choice should match the relief requested. A will-only filing is not the same as opening a full testate estate, and a small estate is not the same as letters of administration for an intestate estate.
Note: The local research did not identify a separate Cass County probate form library, so the heading-change rule should be followed exactly.

Cass County Estates and Publication
Final inventory fees in Cass County probate records are based on estate value. The research lists $50 for $50,001 to $100,000, then increases by $50 increments through $400 for $400,001 to $450,000. Estates over $450,000 use a $450 final inventory fee. The fee schedule states final inventory fees are due for all decedent estates plus a $30 annual fee for each year.
Publication can also be part of a probate case. The Cass County research identifies North Cass Herald at 816-322-2375 and Tribune and Times at 816-540-3500 as local newspapers listed for probate publication. Small estates over $15,000 must be published. Publication is a case step, not just a record search detail, because proof of publication may become part of the probate file.
What Cass County Probate Records Show
Probate records vary by case type. A decedent estate may show the petition, admitted will, letters, inventory, publication entries, accountings, orders, final settlement, and certified copies. A guardianship or conservatorship may show the petition, appointment orders, guardian ad litem activity, annual reports, financial accountings, and court review. Trust and heirship matters may show narrower filings tied to a specific legal question.
Public docket entries are often enough to confirm that a probate case exists, identify the case number, and see the case status. Certified copies are different. Letters testamentary, letters of administration, guardianship orders, and certified court orders are usually requested from the clerk because outside agencies may require a seal or certification before accepting the document.
Restricted Cass County Probate Records
Not every Cass County probate record is open in full. Guardianship and conservatorship files may involve medical, financial, or minor-child information. Mental-health related material can be restricted. Adoption records are treated as restricted family or probate-related material and should not be expected to display like ordinary civil files. Sealed orders, confidential exhibits, and personal identifiers may be withheld or redacted even when a public docket exists.
Missouri public access rules should be read together with court confidentiality rules. Public users can start with Case.net and the Circuit Clerk, but the clerk may limit remote documents, require a written request, or decline access to sealed material. If a person needs a probate record for a related marriage, divorce, or family matter, the custodian should still be chosen by record type. Marriage certificates come from the Recorder, while divorce judgments and probate orders come from the court clerk.
