Clinton County Genealogy Records

Clinton County genealogy records go back to 1833 when the county was organized from Clay County in northwest Missouri. The Recorder of Deeds in Plattsburg holds land records from 1833 and marriage records from 1847, and the Circuit Clerk maintains court files including probate going back to 1833 and divorce records from 1836. Clinton County's courthouse has no known major disasters on record, which means these documents are largely intact across nearly two centuries. Multiple local historical societies and an online search portal further support research for families in this county.

Clinton County Recorder of Deeds

The Clinton County Recorder of Deeds is Misty Dean. The office is located at 211 N. Main Street in Plattsburg, with a mailing address of PO Box 275, Plattsburg, MO 64477. You can reach the office by phone at 816-539-3719, by fax at 816-539-3893, or by email at recorder@clintoncomo.gov. Office hours are 8:00 AM to 4:30 PM, Monday through Friday, with a lunch break from noon to 12:30 PM. Land records in this office go back to 1833, and marriage records go back to 1847. That gives genealogists nearly 180 years of marriage and nearly 190 years of land documentation to search.

The types of documents in the Recorder's custody include real estate deeds, mortgages, tax liens (both state and federal), and military discharge records. Public search terminals are available in the office for researchers who prefer to look through records themselves rather than requesting staff assistance. That is an important detail: Clinton County allows researchers to use in-office search equipment, which speeds up the process significantly when you are looking through a range of years or multiple record types.

Recording fees follow the standard Missouri schedule: $24 for the first page and $3 for each additional page. Copies cost $1.00 per page. Marriage licenses are $46.00, and an important note about payment: the office accepts cash, credit or debit cards, and business checks, but no personal checks as of June 2024. Marriage licenses are cash only. Both parties must appear in person with a valid photo ID and Social Security number. There is no waiting period in Missouri.

An online search portal for Clinton County land records is available at clintonmo.icounty.com. This allows remote access to some recorded documents without visiting the courthouse in Plattsburg.

Clinton County Circuit Court Records

The Clinton County Circuit Clerk maintains court records for the 43rd Judicial Circuit. The Circuit Clerk is co-located with the Recorder in the courthouse at 211 N. Main Street in Plattsburg. Court and divorce records go back to 1836, and probate records go back to 1833. For genealogists, those probate files are especially valuable. They list heirs by name, describe the estate's property, and identify family relationships in ways that census records and vital records often do not. A Clinton County probate file from the 1860s or 1870s can name an ancestor's children, their spouses, and any grandchildren named as contingent heirs, all in a single document.

An important note about how the Clinton County Clerk operates: staff will assist you in finding materials but do not conduct research themselves. If you arrive at the courthouse knowing what you are looking for, such as a specific estate file or a marriage license from a particular year, the staff can direct you to the right record series. If you need someone to search across a range of dates, you may need to do that work yourself using the in-office search terminals or by working through a professional genealogist.

For cases filed after November 12, 2003, you can search online through Missouri Case.net. This free statewide database covers all judicial circuits and is searchable by party name, case number, or date. Cases before that date require a visit to the courthouse or a written request to the Circuit Clerk.

Note: The courthouse has no known fire or disaster history, meaning the 1833 records are intact and accessible.

Vital Records in Clinton County

The Clinton County Health Department in Plattsburg holds local certified birth and death records. Birth certificates are available from 1920 onward, and death certificates from 1980 onward. You need a valid photo ID to request copies and must be an eligible party.

Clinton County also has an older set of vital records kept by the County Clerk rather than the health department. Birth records from 1863 to 1879 and 1883 to 1888 are in the County Clerk's custody. Death records from 1883 to 1888 are also held there. These early records are fragmentary, and coverage is not complete, but if an ancestor was born or died in Clinton County during those specific windows, there may be a local civil registration document on file. This kind of early pre-statewide-registration record is relatively rare, so it is worth checking.

For records from 1910 onward and for any gaps in older coverage, the Missouri Bureau of Vital Records at 930 Wildwood Dr., Jefferson City, MO, phone (573) 751-6387, is the statewide source. Certified copies cost $15.00 each. The free death certificate database at Missouri Digital Heritage covers 1910 through 1969 and has over 9 million records searchable by name at no cost. Each certificate lists cause of death, burial location, informant name, and parents' names.
