In Jainism, there isn’t a simple “more conservative” group when it comes to marriages. Both Digambar and Shwetambar traditions share the same core expectations about married life (dharma, fidelity, family duties, and non-violence).

What you might observe:

• Regional and community practices often shape how strictly certain rites, remarriage norms, and gender roles are observed, more than the sect label itself.
• Digambar and Shwetambar communities may differ in ritual details or specific customs, but these are often about local tradition rather than a fundamental difference in the stance on marriage.
• In both traditions, lay followers typically practice arranged marriages within families, with varying degrees of autonomy and choice, depending on local customs.

If you have a specific context (a particular community or region) in mind, I can explain how that community approaches marriage customs within the Digambar or Shwetambar frame.
