Can i file a case online against my husband for marrying another women i m not in india

Yes, you can file a case as bigamy is illegal in India provided that the marriage was solemnized as Hindu marriage.

You can lodge a criminal complaint against your Husband if he has married another woman without giving a divorce to you. This is an offence punishable u/s 494 Bigamy. You may also appoint any of your relatives to be your POA holder to represent you.

If you have married as per Indian laws and customs, you are the legally wedded wife of your husband. You have two remedies at the moment: to file a case before the NRI commission for fraud committed upon you and file a case for divorce. The case before the NRI commission can be filed online through e-mail but the case for divorce before the court cannot be filed online. But you do not have to come to India to file the case for divorce. It can be filed through an affidavit, if a treaty is present between India and the country you currently residing.

Madam, may i know what type of case you want to file against your husband. Because if he had married in your absence then definitely he had committed a crime and he will also think of an alternative how to protect himself from you. So i personally think that you should think again over the matter and book a consultation with me so that i can guide you in a proper manner after knowing all the facts well so that you will not be in trouble once again, .
