Platte County Obituary Search

Platte County obituary records can be searched through the courthouse in Platte City, the local historical and genealogical society, and several state databases. The county was created on December 31, 1838, from the Platte Purchase, and Platte City has been the county seat since the start. Records at the courthouse go back to 1839. Platte County sits just north of Kansas City, which means it has both small-town and metro-area resources available for obituary and death record research. This guide covers all of them.

Platte County Courthouse Records

The Platte County Courthouse is at 415 3rd Street, Platte City, MO 64079. The mailing address is PO Box 30CH, Platte City, MO 64079. Call 816-858-2232 for general information. The courthouse has several offices that handle different record types. The County Clerk holds birth records from 1883 to 1887 and death records from 1883 to 1888. The Recorder of Deeds manages marriage and land records. The Clerk of the Circuit Court handles divorce records. The Probate Judge manages probate and court records.

Marriage records at the Platte County Recorder go back to 1839. Court records, land records, and probate records all start in 1839 as well. The birth and death records held by the County Clerk cover only a short window in the 1880s, which was part of an early statewide registration effort. For anything outside that range, you will need state-level sources for Platte County obituary and death record research.

Note: Platte County has no known courthouse disasters, so the record chain from 1839 forward is fairly complete.

Platte County Death Certificates

The Platte County Health Department is at 212 Marshall Road, Platte City, MO 64079. Call (816) 858-2412 for vital records information. Birth certificates cost $15 and cover births from 1920 to the present. Death certificates cost $13 and cover deaths from 1980 forward. You need valid ID to get any vital record. Under RSMo 193.255, only people with direct and tangible interest can get a certified death certificate.

For deaths before 1980, reach out to the Missouri Bureau of Vital Records in Jefferson City. They hold death records from 1910 to the present. Records more than 50 years old have been transferred to the Missouri State Archives, where copies run just $1 each. This is the most affordable way to get older Platte County death certificates.

Platte County Historical Society

The Platte County Historical and Genealogical Society is an active group that holds regular meetings and offers research help. They publish newsletters and maintain genealogy collections tied to Platte County families. If you are working on Platte County obituary research for an older family line, this group can point you to local sources you might not find on your own. The Northland Genealogy Society also serves the Platte County area and provides research assistance.

The Platte County Library system has multiple branches throughout the county, each with local history and genealogy sections. Online resources are also available through the library system. Between the library branches and the historical society, there are several in-person options for Platte County obituary and genealogy work. The libraries may hold microfilm of local newspapers that carried death notices and obituaries for Platte County residents over the decades. Newspaper obituaries typically include more personal detail than a death certificate, covering the person's life story, surviving family, and funeral arrangements.

Public Access to Platte County Records

Missouri's Sunshine Law (RSMo Chapter 610) makes public records open for inspection and copying. Vital records have some limits under RSMo 193.245. Recent death certificates need proof of direct interest. But death records over 50 years old are open to anyone. Newspaper obituaries, cemetery records, and the state archives databases are all available to the public for Platte County obituary research.

The State Historical Society of Missouri holds newspaper collections that include Platte County publications. These can be a good source for actual obituary text, since death certificates only show basic facts while newspaper obituaries include the full life story and family details.
