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: covenants against encumbrances; covenants for further assurance (in other words, to do whatever is necessary to rectify title deficiencies); covenants of good right and authority to convey; covenants of quiet enjoyment; covenants of seisin; covenants of warranty. (See Warranty or Covenant.)
