The law distinguishes two basic types. The praedial easement belongs to a plot and benefits the respective owner of the benefiting, that is the dominant plot. The classic example is the right of way that secures the access for the neighbouring plot. Line rights or the right to lead water across the foreign plot also belong here.
The personal easement, by contrast, belongs to a particular person. To it belong above all the right of usufruct, the right of use and the right of habitation. These rights are tied to the person and as a rule end with that person. For the buyer it is important whether, for example, a lifelong right of habitation is registered that can considerably restrict the use of the property.
With the praedial easement there is always a servient and a dominant plot. If you buy the servient plot, you have to tolerate the use. If you buy the dominant plot, you acquire the right along with it. Therefore check precisely on which side your property stands and what scope the right has.
