This discussion explores the legality and permissibility of marrying a relative, specifically a stepmother's cousin's daughter within Hindu traditions. While some initial advice suggests it might be permissible as it's not a blood relation and potentially outside Sapinda rules, further clarification indicates that if the girl is the daughter of the stepmother's sister (mausi), it falls under prohibited Sapinda relationships for Hindus and is generally advised against. However, if she's the daughter of the stepmother's brother, it might be permissible. The consensus leans towards it being legally permissible if not a prohibited degree of relationship, especially if gotras don't clash and parents don't object.
