Covenants ordinarily inserted in conveyances and in transfers of title to real estate for the purpose of giving protection to the purchaser against possible insufficiency of the title received. A group of such covenants known as “common law covenants” includes: (a) covenants against encumbrances; (b) covenant for further assurance (in other words, to do whatever is necessary to rectify title deficiencies); (c) covenant of good right and authority to convey; (d) covenant of quiet enjoyment (see Quiet Enjoyment); (e) covenant of seisin; (f) covenant of warranty. (See Warranty, also see Covenant).
