I understand this is a difficult situation for your family. Here's what you can do:
Legal Jurisdiction:
While your sister's marriage happened in India, her husband currently resides in Saudi Arabia. This creates a complex jurisdictional issue.
Potential Courses of Action:
Indian Courts:
For mushlim, polygamy is legal in India, proving a marriage happening abroad can be challenging. However, you can still explore options in an Indian court:Nullity of Marriage: Since the husband allegedly took a second wife without a proper divorce, or consultation with your sister. your sister can file for a declaration of nullity of marriage in an Indian court. This would legally invalidate their marriage from the beginning.Domestic Violence: If your sister experienced any emotional or financial abuse during the marriage in India, she can file a domestic violence case against her husband.
Considering Saudi Arabia:
Polygamy is legal in Saudi Arabia. However, certain conditions need to be met, including the first wife's consent and fair treatment of all wives. Here, legal options are limited for your sister as she isn't residing in Saudi Arabia.
