Short answer: Yes, Jainism does not prohibit inter-caste or inter-sect marriage. The emphasis is on the spiritual and ethical qualities of the couple and their commitment to the Jain dharma.

Key points:

• Jainism does not base marriage on caste. What matters is mutual respect, consent, and adherence to Jain principles (satya, ahimsa, brahmacharya, asteya, aparigraha) and the duties of a grihastha.
• Inter-sect marriages (for example, Digambara and Śwetāmbara) are possible since both sides are regarded as Jains. In practice, some communities may have traditional preferences or social hesitations, but the religious standpoint does not forbid it.
• The main concerns in any Jain marriage are spiritual alignment, shared values, and the couple’s ability to uphold vows and dharma together.
