This discussion explores the permissibility of marrying a relative within Hindu marriage law. The user is asking if they can marry their father's half-brother's wife's sister's daughter. While the exact relationship is clarified as being akin to siblings, it's debated whether this falls under prohibited 'sapinda' relationships according to the Hindu Marriage Act. The consensus leans towards it being permissible, especially as it might not be a direct blood relation within the prohibited degrees, though community customs can vary.
