Different Divorce laws apply for couples married under Civil Law and Muslim Law in Singapore.
The Family Court in Singapore only grants Divorces to couples who are married under Civil Law.
Matrimonial disputes involving Muslim parties or persons who are married under Muslim law come under the jurisdiction of the Syariah Court under the Administration of Muslim Law Act (AMLA).
You cannot apply for a Divorce in the Family Court if you or your spouse are Muslims, or were married under the Muslim law.
