Clouds on Title is any document, claim, unreleased lien, or encumbrance that may superficially impair or injure the title to a property or make the title doubtful because of its apparent or possible validity. Defects on title are usually uncovered in a Title Search.

When selling real estate the seller will be asked to provide good and marketable title, a title which is free of any liens or judgments, or "clouds on the title." There are several types of liens, all of which could cloud the title and prevent the seller from conveying marketable title to the buyer.

To remove from the record, the property owner may initiate a quitclaim deed or a quiet title proceeding. Also called bad title.
