• Jainism as a teaching does not forbid marriage between people of different castes. The core aims are spiritual progress, non-violence, truth, and right conduct, not caste hierarchy. So from a strictly religious point of view, intercaste marriage is not prohibited. ( jainknowledge.com)

• In practice, many Jain communities still prefer endogamy (within the same Jain community, sect, or caste) due to cultural and social reasons—not because of a doctrinal ban. This is a community/custom practice, not a religious requirement. ( jainknowledge.com)

• If one or both partners are Jains from different castes or sub-communities, Jain teaching itself does not condemn the marriage, provided the couple upholds Jain values and practices. Some modern Jain organizations and scholars acknowledge and support intercaste marriages, while recognizing family and social dynamics can vary. ( jainknowledge.com)

• Note: There is a traditional rule in Jain custom about not marrying within one’s gotra (an exogamy norm). This is a cultural guideline related to lineage, not a universal doctrinal ban on intercaste marriage. Different Jain communities may interpret and apply gotra-related rules differently. If you want, I can point to more about how these customs are viewed within specific Jain traditions. ( jainknowledge.com)

• For guidance in a real-life situation, many couples seek counsel from respected lay Jain elders or community scholars who can explain both the religious principles and the local customs of their community. ( jainknowledge.com)
