Home sellers use warranty deeds to transfer title to buyers. Sellers use deeds to give titles to buyers, but not every deed is equal. A buyer looking for a good title needs a warranty deed. That deed is the seller's legal promise that he owns the land free and clear. It's also his promise to make things right if there is a problem in the future. Warranty deeds approved by legislatures carry the name statutory. That's the type deed a buyer wants.
