A charge on one property for the benefit of another property is called:

A charge on one property for the benefit of another property is known as a predial servitude. This legal concept involves a burden placed on one parcel of land (the servient estate) that benefits another parcel (the dominant estate). The dominant estate gains an advantage, such as the right to cross the servient estate for access or the right to use water from a well on the servient estate. This relationship is rooted in the idea of land use rights that enhance the functionality and value of the dominant property, distinguishing it from other legal arrangements relating to property ownership and use.

In the context of the other choices, a lease agreement refers to a contractual arrangement where one party rents property from another, which does not imply a property benefit relationship between two distinct parcels. A restraint on alienation involves restrictions on the transferability of property, which does not inherently relate to the benefit of one property over another. Joint tenancy is a form of co-ownership where two or more individuals own property jointly with rights of survivorship, rather than involving the benefitting relationship between two separate properties.
