Yes. In Jain communities, whether widow remarriage is allowed or not often depends on local caste/custom rules rather than a universal religious rule.

• In many North Indian Jain communities, widow remarriage is generally not practiced and widows commonly remain in widowhood.
• In parts of South India, some Jain groups historically allowed widow remarriage, though today it may still be uncommon or restricted to specific sub-castes (for example, among certain Deccan castes like Saitavāla and Bogara, the practice has appeared in some periods and places).

Important point: these practices are shaped by local customs within the Jain world, and there is no single Jain rule that uniformly bans or permits widow remarriage across all communities. The Digambara vs. Śvetāmbarā traditions may also reflect differing local practices rather than a fixed doctrinal stance.

If you’d like, I can explain how these differences appear in specific communities in more detail.
