A Muniment or Muniment of Title is a legal term for a document, title deed or other evidence, that indicates ownership of an asset. The word is derived from the Latin noun munimentum, meaning a "fortification, bulwark, defence or protection".[1] Thus "muniments of title" means the written evidence which a land owner can use to defend title to his estate.""
