A servitude was said to exist where X possessed rights in rem over the property of Y. In the following cases, for example, the property of Titinius is encumbered with servitudes in favour to Cassius: Where Cassius enjoys the right of drawing water from a fountain on Titinius's land; where Cassius enjoys the right of sailing on Titinius's lake; where Cassius enjoys a right to the labour of Titinius's slave.
Servitudes might be praedial or personal and praedial servitudes could be rustic (iura praediorum rusticorum) or urban (iura praediorum urbanorum).
