A servitude of right of way based on necessity will be granted where: (1) the dominant tenement is landlocked; (2) there are two separate tenements owned by different persons; (3) both properties are immovable land; (4) the properties are neighbouring; (5) the utility is capable of being transferred; and (6) the benefit is permanent in nature. Necessity for a right of way means it must be the only reasonable sufficient means of gaining access to the landlocked property, not just a convenient means. However, where an existing route is inadequate, causes undue hardship to both the applicant and the property owner through which passage occurs, and has become unavailable (such as through fencing), an alternative route may be found to be necessary rather than merely convenient. The right of way sought must be the only reasonable and feasible route in the circumstances. A servitude of right of way arises by operation of law once the requirements are met, and courts have jurisdiction to direct the specific route to be traversed where parties cannot agree.
