This diploma thesis deals with the Austrian law of maintenance and the calculation of the amount of alimony in particular. The question of a so-called „luxury limit“ to alimony for ex-spouses arose even before the sensational case of „Glock vs. Glock“. In child maintenance law the stopping of maintenance payments is already consistent with the established case law. However, different opinions regarding the level at which such a stop should come into effect persist. These are based on numerous legal opinions, which were formed following several court judgements that are shown in this thesis. Child maintenance law also rejects the implementation of a static luxury limit. The upper limits specified therein can serve as guidelines in similar cases. When it ecomes to extraordinarily high income conditions an examination of single cases is crtainly indispensable. For years now the limiting of alimony for spouses has been firmly opposed by case law. That is why this thesis aims to investigate, if an upper limit in spousal maintenance law can be justified. For this purpose several court judgements and teachings are presented. Alimony is basically intended for the supply of everyday needs and not for the acquisition of personal assets beyond that. A concrete assessment of demand for calculating the amount of alimony would thereby be useful. Furthermore, an early accumulation of capital is not in line with the Austrian legal system. In this context the principle of separation of goods during marriage according to § 1237 ABGB, as well as the separation of goods acquired during marriage subsequent to divorce according to §§ 81 ff EheG are to be mentioned. A comparison to German legal norms is drawn, since Germany has developed an assessment base to determine at which point a luxury limit is appropriate. Finally, the author proposes a possible solution for Austria.
