If your Wali refuses to approve your marriage, you need to make a marriage application first via https://www.marriage.gov.sg/muslim/marriage-process and select the option 'I have a Wali but he does not consent to this marriage'. Once ROMM receives your application, we will assign a Kadi to look into your case. The Kadi will contact you to arrange for an appointment for further enquiry into the matter. The entire process will take approximately 3 months before a decision is made.
