Alimony is compensation given by one spouse to the other spouse for post-divorce financial support, which aims to help the spouse, not punish the other spouse.. In terms of implementation, there are inconsistencies in the application of alimony to Muslim and non-Muslim civil servants. Meanwhile, in Decision Number 650/Pdt.G/2013/PA.Wtp and Decision Number 1051/Pdt.G/2018/PAJT the judge rejected the application of the ex-wife of a Muslim civil servant to obtain 1/3 of her ex-husband's salary. However, in Decision Number 4 / Pdt.G / 2016 / PN Sdw, for former Catholic civil servant wives, the judge granted the request for a 1/3 share of the ex-husband's salary. Thus, there is ambiguity in alimony regulations which causes inconsistencies in the application of law regarding alimony.
