A more thorough explanation:

Fundo Annexa

Fundo annexa is a Latin term used in history to refer to things that are annexed to the soil.

• Buildings and structures that are permanently attached to the land, such as a barn or a shed, are considered fundo annexa.
• Land improvements, such as irrigation systems or drainage ditches, are also considered fundo annexa.

These examples illustrate how fundo annexa refers to things that are physically attached to the land and cannot be easily removed. They are considered part of the property and are transferred with the land when it is sold or transferred.
