A warranty deed offers a higher level of protection than a grant deed. When you're selling or buying a property, it's better to use either general or special warranty deed depending upon the type of guarantee you're looking for.Grant deeds contain two guarantees. First, the grantor states the property has not been sold to anybody else. While a general warranty deed protects the buyer against all possible title defects, a special warranty deed offers a bit less protection for the grantee. A special warranty deed only guarantees that no new problems or encumbrances arose while the grantor owned the property. A warranty deed offers the same promises as a grant deed, and then some. In contrast, a Special Warranty Deed, also known as a limited or grant deed, offers less comprehensive protection. A special warranty deed only warrants against problems in the property title that occurred during ownership of the property. All of the requirements for a Grant Deed are the same as a Warranty Deed.
