Yes, provided you meet the jurisdictional requirements. Your Application for Divorce will just need to be served on your spouse overseas.
Divorce
What if my spouse does not agree to the divorce?
An Application for Divorce can be filed by one party to a marriage so it does not matter that your spouse will not agree provided that you have been separated for one year. To grant a divorce the Court only needs to be satisfied that your marriage has broken down irretrievably, that it is not likely that you will resume the marriage and if there are children of the marriage who are under eighteen years, that there are appropriate arrangements in place for those children.
When can I get divorced?
An Application for Divorce can be filed after a period of separation of one year. The time which makes up one year does not always have to be a continuous period.
In some cases you can add two periods of separation together to make an overall separation period of one year. This can be done provided in the middle of those two separation periods the time you were reconciled and living together as husband and wife did not exceed three months. For example, if you separated and remained separated for four months, reconciled and lived together as husband and wife for three months but then separated again, and remained separated, you can use the first four month separation period to count towards the one year separation period that is required before you can file an Application for Divorce. However if the period you were reconciled in between separations exceeds three months you cannot count the first separation period as part of a one year separation.
