Letters close
Letters close (Latin:litterae clausae) are a type of legal document which is a sealed letter issued by a monarch or government granting a right, monopoly, title, or status to an individual or to some entity such as a corporation. These letters were personal in nature, and were delivered folded and sealed, so that only the recipient could read their contents. This type of letter contrasts with the better-known letters patent.
