How do I check whether my husband has filed a polygyny application?

The surest way is to ask at the counter of the Syariah Court in the district where you live. Bring your MyKad and marriage certificate as proof that you are an interested party. The law requires the existing wife to be called, so a valid application should not be decided without your knowledge. Some courts also offer online case searches through the e-Syariah portal. However, you usually need the case number or details of the parties involved. If you are worried your husband married without permission, the state Islamic religious office can check the registration records. See a wife who was not called.
