A more thorough explanation:

Definition: Right in re propria refers to the right of enjoyment that comes with full ownership of property. It is also known as jus in re propria.

Example: If you own a house, you have the right in re propria to live in it, rent it out, or sell it as you see fit.

This means that as the owner of the property, you have the right to use it in any way you want, as long as it is legal. You can live in it, rent it out to others, or sell it to someone else. This right is an essential part of full ownership of property.
