In Jain tradition, a person’s Jain status isn’t determined by surname alone. The Boliya surname could belong to people who are Jain, Hindu, Muslim, or others, depending on the family history and what they personally practice.

If you want to know about a specific Boliya family, the reliable way is to ask the family members or check their community records, because Jain identity is about current beliefs and practices, not just a family name.
