In Jain Dharma, conversion is not required for marriage.

If a Sindhi girl marries into a Jain family, whether she converts depends on:

• her own choice
• the family’s expectations
• the specific community or sect tradition

From a Jain principle standpoint, marriage itself does not demand conversion. A person may remain in her own faith or choose to follow Jain practices by free will.

Some families may prefer Jain observances, but that is a family or social matter, not a strict Jain religious rule.
