What type of deed offers the GREATEST protection to the buyer (grantee)?

DEED TYPES AND PROTECTION LEVELS: GENERAL WARRANTY DEED (most protection): The grantor warrants the title against ALL defects, including those that arose before the grantor owned the property; includes full covenants (seisin, against encumbrances, quiet enjoyment, further assurance, warranty forever); the grantor will defend against all claims; SPECIAL (LIMITED) WARRANTY DEED: Warrants only against defects that arose DURING the grantor's ownership — not before; QUITCLAIM DEED (least protection): Transfers whatever interest the grantor has (if any) with NO warranties — used to clear clouds on title, between family, or in divorce; if the grantor has no interest, the grantee gets nothing; BARGAIN AND SALE DEED: Implies the grantor holds title but offers limited or no warranties (varies); FOR BUYERS: The general warranty deed provides the greatest protection and is preferred in most arms-length sales; the level of warranty (general > special > bargain and sale > quitclaim) is a core national exam topic.
