什麼是地役權?

This is the exact wording for Section 36 of District Court Ordinance (Hong Kong Ordinances Chapter 336).

Easement is not really a legal term, but a real estate term (although it uses mostly in legal aspect).

In short, an easement is a right given to a non-owner to have access of a particular area or interest.

In Hong Kong, a typical example of an easement is the area used for public utilities (electricity, phone, etc.) within a real estate development. This area, based on the Government Lease, is the public area of the development, which is under the control of the Owners' Corporation and property management.

The easement allows the public utility companies to enter the area and install necessary equipments to serve the development.

Another example of easement is roads connecting to the car park of a residential area. The owner of the parking spot does not own the road. Yet, the owner is given the right to use the roads in accessing the car park.

地役權，通常指依據契據或遺囑，土地使用人在他人擁有的土地上能享有的非營利利益，土地使用人藉此能夠獲得對此一土地特定的有限使用權利。[1]是指為了使用自己土地的便利而使用他人土地的權利。例如，擁有A地的甲可以要求擁有B地的乙不要在其土地上建設高樓以保證甲可以觀賞遠處的風景。

鐵路地役權
鐵路地役權是一種由政府賦予鐵路公司（或鐵路部門）預留鐵路建築用地的地役權。一般而言在鐵路路線被荒廢或企劃的路線確定不被實行，預留地會歸還給原地權使用者，但此一政策亦會因地方而異。
