n. a deed to real property which guarantees that the seller owns clear title which can be transferred (conveyed). A grant deed generally is a warranty deed, while a quit claim deed is not. (See: warrant, grant deed)
A general warranty deed is the standard means by which real property is transferred in the United States. True to its name, it provides the buyer with a warranty that the title to the property in question is free from encumbrances and won't be the subject of any pending legal actions or title issues.
