A more thorough explanation:

A freeholder's court baron is a type of court baron that pertains to a freehold estate or interest. A freehold estate is a type of property ownership where the owner has full and permanent ownership of the property, as opposed to a leasehold estate where the owner only has temporary ownership rights.

For example, if someone owns a house and the land it sits on, they have a freehold estate in that property. This means they have the right to use, sell, or transfer the property as they see fit, as long as they comply with any legal requirements.

In England, there were also freehold land societies that were created to help workers buy freehold land at a low price. These societies allowed workers to have a sufficient yearly value of land that entitled them to the right to vote in the county where the land was located.

Overall, a freeholder's court baron is a legal term that relates to the ownership and transfer of freehold property rights.
