Answer

Yes, Kathed (also written as Kathad / Kathed in some places) can be found among Jain communities, especially in certain regions and business-family lineages.

However, a surname alone does not always prove that a person is Jain. Many surnames are shared across different communities depending on region, history, and family background.

Takeaway

Kathed may be a Jain surname, but the sure way to know is by checking the family’s tradition, sect, kuldev/kuldevi, gotra, or community history.
