Whether Notary Public has to ensure that proper stamp duty is paid on instrument?

Before doing any Act of Notary, it is the duty of the Notary to ensure that the proper stamp duty is paid, if not he may impound it under Section 33(1) of the Stamp Act. Apart from the regular stamp duty, the act of Notary attracts additional stamp duty under Article 42 of Indian Stamp Act and Article 36 of Karnataka Stamp Act, which is Ten Rupees.
