While Special Warranty Deeds are mostly used for commercial property transactions, they are a variation of the General Warranty Deed, which is the instrument generally used for residential property transactions and the preferred type in the United States. The main difference between these two documents is the timeframe of protection given to title ownership because General Warranty Deeds cover the entire history of the property. There is another document to convey a title to real property that is called Quitclaim Deed. These are usually drafted and signed between family members or parties who know each other, as they are Deeds that do not offer buyer protection. Quitclaim Deeds may also be used to correct an error on the title, or when there is no money involved in the transaction.
