The oath or affirmation by the Vice-President of India is provided for in:

• He swears to faithfully discharge the duty upon which he is about to enter.

Difference from the President's oath:

• The President's oath under Article 60 is administered by the Chief Justice of India, or in his absence the senior-most judge of the Supreme Court.
