I believe your husband's first marriage is dissolved.
Your husband and his ex-wife----------when they faught divorce in australia...they were domiciled there last and last cohabitation is in australia. It's well within Australian jurisdiction as well.
Is it based on fault theory or 'unilateral no fault divorce'???
Is there any stay of execution of decree of divorce, obtained by ex-wife after the divorce decree?? (there is limitation period for appeal)
After comming to india ex-wife filed cases of harrasement and maint (crpc125??) it doesnot mean that divorce decree set aside in indian court.
Find out the details.
And anyways 'divorce case' is going on in india................. not RCR or to restore earlier marriage right??
So question is ............who's to be awarded divorce and who's to be slapped with it (it's an irony really......but it gets applicable to both technically)
