A more thorough explanation:

hors de son fee

hors de son fee is a legal term that means "out of his fee." It was used in the past as a defense in a lawsuit over rent or services. The defendant would claim that the land in question was not part of the plaintiff's property.

For example, if a landlord sued a tenant for not paying rent, the tenant could use hors de son fee as a defense if they believed that the property they were renting was not actually owned by the landlord.

Another example would be if a farmer was sued for not providing services to a neighboring farm. The farmer could use hors de son fee as a defense if they believed that the land they were being asked to work on was not actually owned by the neighbor.

These examples illustrate how hors de son fee was used as a legal defense to challenge the ownership of land and property in a lawsuit.
