In this type of deed, the seller does not guarantee that their title is free and clear of any defects before the seller acquired the title or ownership of the property.A special warranty deed generally contains this similar clause:“Grantor does hereby bind Grantor and Grantor’s heirs and legal representatives to WARRANT AND FOREVER DEFEND all and singular the Property, subject to the matters set forth in this Special Warranty Deed, unto Grantee and Grantee’s heirs, legal representatives, and assigns, against every person whomsoever lawfully claiming or to claim the same or any part thereof, by, through or under Grantor, but not otherwise.”Quit Claim DeedQuite contrary to general warranty deed and special warranty deed, a quit claim deed does not establish title of the seller in the property.
