For KCET, it is generally recommended to have a valid caste certificate during the document verification process to avoid any issues.There is no clear and official confirmation on whether KCET will accept an expired caste certificate during document verification.In some past cases, KCET might have accepted expired certificates in rare situations. However, it is not a guaranteed practice.
