From a Jain dharmic and traditional point of view, marriage is generally preferred within the Jain community so that ahimsa, vrat, sanskars, and daily religious practice can be preserved.

For a Jain marrying a person from Maratha/Kanbhi/Kunbi or any non-Jain community:

• It is not usually encouraged by Jain families and community traditions.
• In many Jain households, it may be considered a deviation from religious and cultural continuity.
• However, the final acceptance often depends on family tradition, sect, and local community norms.
• If the other person respects Jain values and the couple is committed to preserving Jain way of life, some families may still consider it.

So, from Jain tradition, it is possible in a worldly sense, but generally not preferred religiously.

In short: Jain marriage is ideally with a Jain partner.
