In India, there is no legal requirement for a Hindu married woman to wear a Mangalsutra, even after filing for divorce or during proceedings like MC-CRPC 125. The decision to wear or not wear a Mangalsutra is a personal choice and has no bearing on the legal validity of the marriage or divorce. Indian law does not consider it as evidence of marital status or misconduct, and courts do not typically inquire about it as it holds no legal significance.
