In order to have a detailed list of the possessions you own, you can make an inventory: it catalogs the objects, noting their quantity, origin, characteristics and quality. Eventually it can be used to provide the size of an asset, whether owned by an individual, family or corporation, and will express it through a valuation.
Where an estate has multiple objects an inventory may be required for an inheritance or for divisions, but it is also the most appropriate tool for protecting the integrity of a collection.
