A dominant estate is also called a Dominant tenement, as noted in a section of an article on easements.
In real estate law, this is the poperty retained when the original owner (the seller or grantor) splits off a property and conveys part of the original property; the owner retains an easement for an access (such as a driveway or utilities).
In certain cases, dominant estate refers specifically to a parcel or building premises that is subject to a cell tower or a solar panel: "that parcel of land to which the benefits of a solar access easement attach."
It is not clear whether all community property states have the same concept, but it is recognized in Arizona and Texas.
