A general warranty deed provides the highest level of protection to the grantee (purchaser). The grantor makes several legally binding promises, known as covenants of title, that warrant the quality of the title against any and all past and future claims. These covenants, including the covenant of seisin, quiet enjoyment, and warranty forever, cover the entire history of the property, not just the period the grantor owned it. This comprehensive guarantee obligates the grantor to defend the title against any third-party claims, offering the purchaser maximum security and legal recourse.

A. quitclaim deed: This deed offers no warranties. It merely conveys whatever interest the grantor may have, if any, providing the least protection to the purchaser.

B. trustee’s deed: This is a form of special warranty deed that typically only warrants against title defects that arose during the trustee's period of ownership.

D. deed in trust: This instrument is used to transfer property into a trust, not to sell it to a third-party buyer; it does not offer title protection in a sale context.
