Unregistered polygamous marriage carried out by civil servants has serious implication for wives’ financial problem, social fate and loss of children’s welfare. The Marriage Law allows polygamy with very strict requirements. In the Government Regulation governing civil servant polygamy, justice is the main requirement in polygamy, because it really determines welfare in polygamy families. Based on the results of in-depth interviews and participant observation by using the constructivism paradigm and socio-legal approaches, it was found that unregistered polygamous marriages carried out by civil servants have implication for the disciplinary punishment of employees, so the polygamists got the sack. This implies their family economic problems, because there is not enough income to meet the needs of family life. Finally, neglect and divorce occur. Wives and children will be victims. Hence, it is necessary for the government to regulate particular policies for the polygamists of civil servants, to save their wives and children’s life. Firing the polygamists is not such a solution, but will instead create more complicated problems for their families
