About Thomas County
Thomas County is northwest Kansas’s I-70 service hub and Prairie Museum county – Colby’s excellent regional museum and strategic interstate position make it the commercial and cultural anchor of a vast High Plains agricultural region.
Colby (the county seat, population ~5,600) is the dominant commercial center for northwest Kansas – its I-70 position brings travelers, and its retail, healthcare, and educational facilities (Colby Community College) serve a broad region. The Prairie Museum’s 24-acre campus is one of the most comprehensive High Plains agricultural heritage sites in the country.
The Ogallala Aquifer beneath Thomas County sustains irrigated corn and wheat production that would be impossible in this semi-arid climate without groundwater.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Thomas County District Court, 15th Judicial District 300 North Court Avenue, P.O. Box 805, Colby, KS 67701 (785) 462-4540
Thomas County was founded October 8, 1885, named for Union general George Henry Thomas. Its seat, Colby, sits along Interstate 70. The 1906-1907 Thomas County Courthouse (Richardsonian Romanesque, National Register of Historic Places) is a distinctive local landmark.
Step 1: figure out which path applies
Kansas has NOT adopted the Uniform Probate Code, maintaining its own statutory framework under the Kansas Probate Code (K.S.A. Chapter 59). Kansas offers several tracks depending on estate size and complexity:
Small Estate Affidavit – for estates where the total value of probate property, less liens and encumbrances, does not exceed $75,000 (raised from $40,000 effective July 1, 2023), available under K.S.A. 59-1507b. This transfers personal property only. If the decedent left a will, it must still be filed with the probate court even though it isn’t being formally probated.
Simplified Administration – under the Kansas Simplified Estates Act (K.S.A. 59-3201 et seq.), the most common route for straightforward estates.
Formal Probate – supervised or unsupervised administration through the District Court for larger or more complex estates.
A will must be filed for probate within 6 months of death, or it may not be admitted, forcing the estate into intestate distribution.
Step 2: filing for formal probate
File a Petition for Probate of Will and Appointment of Executor (if there’s a will) or a Petition for Administration (if intestate) with the Thomas County District Court.
The court admits the will (if any) and appoints the personal representative.
Notice to creditors is published per court order; creditors have a defined window to file claims.
The personal representative inventories assets, pays valid debts and expenses, and – under unsupervised administration – acts with reduced court check-ins.
Without a surviving spouse or children, Kansas intestate succession law (K.S.A. 59-501 et seq.) determines which blood relatives inherit.
After debts are paid, the personal representative distributes assets and files a final accounting; the court closes the estate upon approval.
What it costs
Court costs may be remitted for small estates under recent statutory changes.
Executor/administrator and attorney fees are generally reasonable-fee based rather than a fixed statutory percentage.
Typical timelines: Small Estate Affidavit can proceed relatively quickly; formal probate commonly takes several months to over a year.
