Swiss Civil Code

¹ Where a per­son in­curs or is at risk of dam­age be­cause a landown­er acts in ex­cess of his or her own­er­ship rights, he or she may sue for abate­ment of the dam­age or for pro­tec­tion against any im­min­ent dam­age and for dam­ages.

² Where a build­ing or in­stall­a­tion de­prives a neigh­bour­ing par­cel of land of cer­tain prop­er­ties, the afore­men­tioned rights ap­ply only if the reg­u­la­tions that ap­plied at the time the build­ing or in­stall­a­tion was con­struc­ted were not com­plied with.⁵⁴⁹
