accessionI
accessionI is a term that can refer to several distinct concepts, primarily within the realms of law and genealogy. In a legal context, accession refers to the acquisition of property through a natural or artificial process. This can occur when something is added to existing property, such as a building constructed on land, or when a river changes its course, altering property boundaries. The law of accession dictates who has ownership rights to these additions or changes.
In genealogy, accession refers to the process of becoming a member of a family, often through marriage
Historically, the term accession was also used to describe the formal act of adding a new territory
