Expungement Process in Platte County
People with old criminal records in Platte County may be able to get them expunged. Under RSMo 610.140, certain offenses can be sealed from public view. You file a petition with the 6th Judicial Circuit Court. There is a filing fee. The waiting period is three years for misdemeanors and seven years for felonies, counted from when the case fully closed.
Not every crime qualifies. Class A felonies, dangerous felonies, and sex offenses are excluded. The prosecutor gets notice and may object. If they do, the judge holds a hearing. If the petition is granted, the Platte County Circuit Clerk seals the case file. It drops off Case.net. The Highway Patrol removes it from the MACHS database. Law enforcement records tied to the case also get sealed. After that, the person can legally say the arrest and charge did not happen. Given that Platte County is in the Kansas City metro, this process gets used fairly often compared to smaller rural counties. An attorney can help determine if your specific Platte County case qualifies. The current filing fee is available from the clerk's office at (816) 858-2232. Legal aid organizations in the Kansas City area may also help people who qualify for free legal services with the expungement petition process.
