According to the Oklahoma Department of Public Safety, it is not legal to take ownership of an abandoned vehicle on public property. However, if you find an abandoned vehicle on private property, you may be able to claim it as your own if the owner cannot be located.
To do so, you must first file a report with the local police department or sheriff's office. Once the report is filed, you will need to place a notice on the vehicle stating your intention to take ownership. The notice must include your name and address, as well as the date that you placed the notice.
You will then need to wait at least 30 days before taking possession of the vehicle. If during that time period, the rightful owner does not come forward and claim the vehicle, you may then proceed with taking ownership.
