My father owned a flat, and I want to transfer it to my name after his passing. I got an heirship certificate from the Tahsildar, but the authorities say it’s not valid. They claim the Tahsildar isn’t the right person to issue such a certificate. Is this true?

Yes, the Tahsildar is not authorized to issue heirship certificates. These certificates are typically issued by the competent court or a designated authority, depending on the specific state laws. The authorities are correct in rejecting the Tahsildar’s certificate as it is legally invalid.
