Rewrite this statement in your own words:

"An easement by necessity can only be created when land held by a single owner is separated into two or more parcels. It allows an owner of a landlocked property to cross over another's land in order to access a public road. If any of the newly created parcels is physically unable to reach a public road, an easement by necessity may be created. An easement by necessity will not be granted only for purposes of convenience. Some real necessity must exist. Easements by necessity are either granted to a buyer of a landlocked parcel, or reserved by a seller of land who retains a landlocked parcel after the separation and sale. There are 3 requirements to acquire an easement by necessity:

"a. Both the dominant and servient estates must have been owned by the same person before the need to access the dominant estate arose.

b. The need for an access easement was created by the subdivision of the commonly owned land.

c. The easement is necessary to use the dominant estate.""
