If Nancy owns the property that Heather crosses over to get to her own property, what term describes Nancy's ownership of the parcel?

Nancy's ownership of the parcel is described as servient because her property is being crossed over by Heather in order to access her own property. In property law, the term "servient" refers to a property that is burdened by an easement, which is the right for another party (in this case, Heather) to use a portion of that property. The parcel that grants this easement is known as the servient estate, while the property that benefits from the easement is called the dominant estate. Thus, Nancy's ownership is correctly classified as servient since her land is being used to provide access to Heather's land.
