Answer

In Jain customary practice, a marriage is usually checked by gotra/lineage and known ancestry, not by a shared title or surname alone. Jain sources say that marriage rules vary by community and locality, that a partner should belong to a different gotra, and that among Śvetāmbara Terāpanthi Osavālas surnames are sometimes used as the marriage filter. So, if the only common point is the title and no common ancestor is found, it is generally not an automatic prohibition. ( jainworld.jainworld.com)

Explanation

From the Jain social tradition, the key question is: Are you from the same family line or gotra? If the answer is no, then the shared title by itself usually does not create a restriction. At the same time, Jain custom is not uniform everywhere, so families and community elders may follow local Terapanth practice differently. ( jainworld.jainworld.com)

Spiritual Understanding

Jain teachings treat marriage as a social and household matter, not as a sacrament with one fixed universal scriptural rule. That is why lineage checks, family custom, and community guidance matter in practice. In simple terms: same title is not the main issue; same bloodline or same exogamous family line is the real concern. ( jainworld.jainworld.com)

Takeaway

If no common ancestor is found and the gotra/lineage is different, the marriage is usually considered acceptable by custom. For full certainty in Terapanth Śvetāmbara tradition, the final check should be done through family elders or community genealogy records. ( jainqq.org)
