- As per law, a Mutual Consent Divorce granted by foreign Court is considered as valid, legal and binding in Indian Courts by virtue of section 13 and 14 of CPC and also on account of comity of Nations.
- Further, if the matter is contested between parties in US Court, and after due adjudication and trial, divorce is granted, then it will be valid and binding in India.
- Since, your sister is living in India, then in her absence the said decree of divorce granted by the US Court will have no legal value in the eye of law , and legally there will be no divorce and she will be his legal wife
