Demesne as of Fee Law and Legal Definition

Demesne as of fee refers to the complete ownership of something.

“But there is this distinction between the two species of hereditaments: that, of a corporeal inheritance a man shall be said to be seised in his demesne, as of fee; of an incorporeal one, he shall only be said to be seised as of fee, and not in his demesne. For, as incorporeal hereditaments are in their nature collateral to, and issue out of, lands and houses, their owner hath no property, dominicum, or demesne, in the thing itself, but hath only something derived out of it; resembling the servitutes, or services, of the civil law.”
