What is the process of acquiring additional property known as?

The process of acquiring additional property is referred to as accession. This term is particularly used in legal contexts to describe the process whereby an individual gains ownership of property by means of natural or artificial additions to existing property. Accession can occur through methods such as the addition of fixtures, natural growth of property, or other means of enhancement that increase value or utility.

Accession illustrates how an owner can legally obtain increased rights to property through the integration or incorporation of new elements with existing property. For instance, if a tree grows and provides more wood, the tree owner benefits from this added value through accession. The focus of this term is not just on the transaction of buying or acquiring but on the enhancement of existing ownership through addition.

In contrast, the other terms do not accurately identify this process. Accumulation pertains more to gathering or amassing something over time, but does not directly address the legal nature of property acquisition. Acquisition generally implies the act of obtaining property but lacks the nuances related to the addition of value through growth or attachment. Extension typically refers to expanding existing boundaries or operations, which may not directly relate to the legal principles governing property ownership and rights of addition.
