How do I file for a divorce with my husband if he’s working overseas and not physically present in Singapore?

If your husband is willing to accept service of the divorce documents via email and is agreeable to the terms of the divorce and ancillary matters, the process is much simpler. If he is not willing, the divorce will need to be filed on a contested basis and you will need to file a separate application for service out of jurisdiction. In short, do-able but more time and legal fees required.
