It would look like 'dominant and servient lands/proporties/estates/...' (whatever your context determines it is).

'Easements require the existence of at least two parties. The party gaining the benefit of the easement is the dominant estate (or dominant tenement), while the party granting the burden is the servient estate (or servient tenement).

For example, the owner of parcel A holds an easement to use a driveway on parcel B to gain access to A's house. Here, parcel A is the dominant estate, receiving the benefit, and parcel B is the servient estate, granting the benefit or suffering the burden.' (wikipedia)
