Mylar Maps / Plat Maps / Subdivision Maps

 A Mylar Map (or Mylar Subdivision Map or Mylar Plat Map) is a map printed on Mylar material (a durable transparent film). This map is created to indicate the subdivision of a piece of land into smaller parcels or indicates the details of a single property such as property lines, easements, restrictions etc. In some cases, the map is laminated rather than printed on mylar. If the map is to be officially recorded at a local recording office, it must first be notarized.

Because of the plastic nature of the document, the Notary's official ink seal can not adhere to it. For this reason, a California statute allows an exception when authenticating this official notarial act without the use of the Notary's ink commission stamp.
