Dear Client,

In this case, your sister can file a case in this regard and can force her husband to return to India. She can file a complaint under Section 86 of the Bharatiya Nyaya Sanhita (BNS) and under the Muslim Women (Protection of Rights on Marriage) Act, 2019, for triple talaq, which is illegal and void under Indian law. She must immediately lodge a police complaint which would also raise the issue of LOC wherein he would not be able to travel to India without answering the case. Your sister can also seek a maintenance remedy under Section 144 of BNSS  and initiate proceedings for divorce if she wants. Moreover, you can also approach the Indian Ministry of External Affairs by writing to the Indian Embassy in Dubai requesting them to cooperate in extraditing her husband to India so that she may face the legal procedure. Hire an attorney who is qualified enough to file cases and communicate with authorities to expedite the process.

Hope that this helps you to solve your problem.

She can file a police complaint if her husband has given her triple talaq. The practice of triple talaq was declared unconstitutional by the Supreme Court of India in August 2017. Following this, the Muslim Women (Protection of Rights on Marriage) Act, 2019 was enacted, which makes the practice of instant triple talaq illegal and punishable by law.

She may also file for domestic violence and dowry harassment and seek maintenance and other rights under the law.

Triple talaq in one go is no more valid and a crime as well. 

Looks like this marriage has gone dead. So instead of pursuing it , your sister better seek redress udner law for the atrocities done to her and for giving her unlawful Talaq.

You can extradite him now. You can file domestic violence and maintenance cases against him in India and get him convicted then you can take further steps to issue LOC against him

Some legal proceedings can be good remedial points here to get relief in this matter. 

The husband is legally bound with the wife which is a mandatory point here. 

Dealing with a situation involving an extramarital affair, alleged abuse, and the pronouncement of triple talaq from abroad is complex and requires careful legal navigation. Here are the steps and options available to address this issue:

Legal Considerations on Triple Talaq

1. 
   Triple Talaq Law in India: As of 2019, the practice of instant triple talaq (pronouncing "talaq" thrice in one sitting) has been made illegal in India and is punishable by law. This law provides a means to seek redress and potentially enforce the husband’s return to India for legal proceedings.

Strategies to Address the Issue

1. Criminal Complaint in India:

   • You can file a criminal complaint in India under the relevant sections of the Indian Penal Code (IPC) for domestic abuse and under the Muslim Women (Protection of Rights on Marriage) Act, 2019 for illegally pronouncing triple talaq.
   • The complaint can be filed at the local police station in your sister’s hometown. The police can initiate action, which might include contacting Interpol for assistance if he refuses to return and face charges.

2. Legal Notice:

   • A lawyer can draft a legal notice to be sent to him (if his address is known) or to his family in India, demanding him to return to India and settle the matters legally. The notice can outline the legal actions being considered against him.

3. Approach the Indian Embassy:

   • Contact the Indian Embassy in Dubai detailing the situation. They can offer guidance, and in certain cases, they might be able to facilitate some form of mediation. Although they cannot enforce his return, they can provide necessary support and information.

4. Civil Remedies:

   • File for restitution of conjugal rights in India if your sister wishes to continue the marriage.
   • Alternatively, she can file for divorce on the grounds of cruelty and adultery, which could also involve claims for alimony/maintenance.

5. Seeking Help from NGOs:

   • There are several NGOs and women's rights organizations both in India and Dubai that can offer legal assistance, advice, and possibly intervene in some capacity.

Extradition Feasibility

• 
  Extradition from UAE to India for family law disputes, especially those involving marital issues like triple talaq, is highly unlikely. Extradition typically applies to criminal charges deemed severe by both countries' laws and involves prolonged legal procedures. However, if he commits an offense that is recognized criminally in both jurisdictions, this might become a possibility.

Practical Steps

1. Document and Gather Evidence:

   • Ensure that all evidence of the extramarital affair and any instances of abuse are securely documented. This includes any communications, photographs, or testimonies that can support the case.

2. Legal Representation:

   • It's crucial to engage with a lawyer who specializes in family law and understands the nuances of international law, especially laws relating to the rights of Indian citizens abroad and the implications of UAE laws.

3. Financial and Emotional Support:

   • Make sure your sister has the financial means and emotional support to go through what can be a challenging process. Consider setting up counseling sessions for her to cope with the mental and emotional stress.

Conclusion

Addressing these issues effectively requires a combination of legal actions, diplomatic approaches, and personal support systems. The primary goal would be to ensure your sister’s safety and legal rights are upheld, considering the complexity of international jurisdiction and marital laws.
