Land is as old as time itself. Like the structures built on it, land is ''real property,'' meaning that it can't be moved or hidden. Because real property is valuable, many people want to claim ownership. ''Titles'' came about as a means of legally proving who owns the property.
Through the centuries, however, a parcel of property may change hands dozens of times. At any point along the chain of ownership, problems may arise that cast a ''cloud'' over a title, putting a claim of ownership in doubt.
