Divorce by mutual consent obtained abroad is valid in India 

you can if you so desire file petition in family court for declaration that marriage is dissolved by Australian divorce decree 

As your divorce was finalized in a non-reciprocating territories, the foreign decree can be enforced only by filing a suit in the district court for a judgment based on that foreign judgment.

If your foreign decree fulfills all the conditions provided under Section 44A CPC, it can be executed in India as if it was a decree passed by the District Court. After that, you can remarry.

1. Since Australia is not recognised as one of the reciprocating countries by Indian Government, the order of divorce obtained from Australian Court has to be revalidated in India by the jurisdictional Indian Court.

2.  You can remarry after the above procedure is carried out.

If it is a divorce decree on the grounds of mutual consent, then it can be held as legally valid in India for the marriage that was solemnised as per Indian laws. 

If your marriage was not registered in India but registered only in Australia then it can be termed as a marriage as per Australian laws, therefore the divorce granted legally as per Australian laws is valid which cannot be disputed in india. 

If that is the situation there may not be any bar for you to marry a girl in India as per Indian laws provided you produce the divorce decree copy before the marriage registrar in India to prove that you are a divorcee.

Dear Client,

Yes you can serve a divorce notice from Australia also but the proceeding will be in India. 

If you give her divorce in Australia then it will not be valid in India. You have to file divorce in India only then it so possible.

There is also an option of seeking a divorce by mutual consent where both parties amicably resolve conflict and get divorced.

If you intend to remarry, you must give your marriage celebrant a Notice of intended marriage at least one month before the wedding date, and comply with other requirements of the Marriage Act 1961. You may complete and lodge the Notice of intended marriage with your authorized celebrant before the divorce order is finalized, but the celebrant must sight a copy of the divorce order before the wedding can take place.

Be prepared to provide the exact date of your divorce, as well as the state or country where the divorce was decreed, the exact grounds for divorce, and whether your former partner is still alive. It sounds morbid, but in order to ensure your union is a legal one, your local government will need to be absolutely sure that you're no longer married to your former partner. Once that's done, you're all set to get remarried.

Thank You.
