The cases mentioned are already decided by the high court (Supreme Court here). It simply means that the Filipino spouse can get married only when the divorce has been declared, in which such action was initiated by the foreign spouse. Why foreign? because Filipinos are covered by Philippine laws wherever they may be and since we don't recognize divorce, then essentially, Filipinos can't get divorced. But that also depends on the marriage law of the country of the foreign spouse. that is another discussion.
So, if you want to get divorce, let the foreign spouse initiate it so that when the divorce is approved, you are free to marry either in the Phils or abroad.
The divorce must be secured by the foreign spouse so that Filipino spouse can get married. Yes, the Filipino spouse is free to marry abroad but that marriage is bigamous under Philippine law since he/she hasn't gone through annullment/divorce.
Correct.
