In Jainism, there is no doctrinal ban on a Jain from one sect (for example, Shwetambar) marrying a Jain from the other sect (for example, Digambar). For lay Jains, inter-sect marriages are generally acceptable and do occur. The important thing is mutual acceptance of each other’s sect-specific practices and rites, and clear agreement about how wedding rituals will be observed.

Key points to keep in mind:

• The differences between Digambar and Shwetambar are mainly in monastic codes and some temple/ritual practices; among lay Jain households, these differences are usually manageable.
• The marriage itself is a social and religious contract between two families, and the couple should agree on how to perform rites that are customary for their families.
• Monastic vows and rules (for monks and nuns) are separate from household marriages; inter-sect issues do not apply to renunciants.

If you meant something more specific by “Vidhyadhari” (which isn’t a standard Jain term I can clearly identify), please clarify that term, and I can tailor the answer more precisely.
