In general, when divorce proceedings are commenced, you and your lawyers would have to serve the divorce papers personally on your spouse.
However, if you are not able to locate your spouse and have lost all contact with him or her, you can still proceed to apply for divorce. You would have to furnish evidence that you have tried all means (e.g. email, telephone, Facebook, contacting relatives) to contact your spouse to no avail.
Allow us to take it from here.
We offer a free 30-minute consultation with one of our family lawyers.
