What is the term for the right to all that one's own property produces, including additions from natural or human action?

The correct term for the right to all that one's own property produces, including additions from both natural and human action, is accession. Accession refers to the legal principle that allows property owners to claim ownership of all improvements and additions made to their property, whether through the passage of time or through intentional actions. This includes anything that becomes a permanent part of the property, such as buildings, crops, and any alterations or enhancements that increase its value or utility.

Accession highlights the connection between the owner and the property, emphasizing entitlement to both natural growth and human-made improvements. In this context, a property owner has rights to the benefits derived from their land, reinforcing the concept of ownership and the ability to benefit from one's investment in the property.
