Quieting title is a process to determine ownership of property when there is a disagreement about who is the legal owner.
If you purchased a car and have had a hard time getting title in your name, you may be able to use this process to settle the question of ownership of the vehicle. Some people call it applying for “ownership in doubt.”
Washington LawHelp has some general information about this situation as well as instructions and forms.
If there are issues with title to land/buildings (often referred to as 'real property'), the law library has materials to learn more about quieting title for these situations.
