The lawsuit that asks a court to declare who owns a property and to remove a competing claim from the record - used to clear an old mortgage never released, a break in the chain of title, a tax-sale or adverse-possession claim, or a deed that should never have been recorded.
A quiet title action is a civil suit in which the plaintiff asks the court to determine the rights of everyone who claims an interest in a parcel and to enter a judgment establishing the plaintiff's title against them. It is the remedy for a cloud on title - any recorded instrument or claim that appears to give someone else an interest and that a buyer, lender or title company will not ignore: a mortgage paid off decades ago but never released, a lien in a prior owner's name, a deed from an estate whose heirs were not all identified, a boundary line disputed by a neighbour, a forged or fraudulent conveyance, a tax deed of doubtful validity, or the plaintiff's own claim by adverse possession.
Because a judgment binds only the parties to it, the suit must name every person and entity with a possible claim, and where they cannot be found - a lender that no longer exists, unknown heirs of a long-dead owner - the court permits service by publication after a diligent search, and appoints a guardian for unknown or absent parties in some states. The plaintiff proves their own title, not merely the weakness of the defendant's; a person with no title of their own cannot quiet it against anyone. The judgment, once recorded, becomes part of the chain of title and is what the title insurer relies on to remove the exception.
Many states have simpler routes for the commonest clouds: a statutory affidavit or an action to compel release of a satisfied mortgage, a marketable-record-title act that extinguishes claims older than a stated root of title, a curative statute that validates deeds with minor defects after a period, and a partition action where co-owners disagree. Against the United States, a quiet-title suit is permitted by a specific federal statute with its own limitation period and conditions; against a state, sovereign immunity may bar it entirely.
The pleading is the whole case: a defendant omitted is a cloud not removed, and a judgment against unknown parties is only as good as the diligent search behind it, so this is an action to have a lawyer bring rather than file from a form. A person facing a quiet-title complaint - typically served by publication and easy to miss - should respond by the deadline, because a default judgment quiets title against them just as effectively as a trial would.
Choose your state. Each link opens the directory page for the city in that state with the most currently published law firms in this practice area; a +n beside the city is how many other cities in the state also have one. The list is generated when this page loads, so a state whose listings have lapsed drops out rather than becoming a dead link.
