Land may appear freely available even though another person uses part of it. The arrangement may be a lease, tenancy, loan for use or simple permission. That classification helps determine which documents the buyer needs and whether the use continues after the change of ownership.
Before the purchase, the buyer should identify the user, the area, access, duration, payment, deposit and outstanding obligations. An oral agreement or a right that is not visible in the land register cannot simply be treated as irrelevant.
This article explains how leases and other third party use rights should be addressed in the purchase contract. Section 1120 of the Austrian Civil Code shows that a change of ownership does not automatically end an existing tenancy or lease. Whether and to what extent that rule applies depends on the agreement, the type of use and the facts of the case.
