4.1. Renunciation of Citizenship (Section 8)

If any citizen of India of full age and capacity, who is also a citizen or national of another country, makes a declaration renouncing his Indian citizenship, then that person shall cease to be a citizen of Indian. Provided that if any such declaration is made during any war in which India may be engaged, registration thereof shall be withheld until the Government of India otherwise directs.

Where a person ceases to be a citizen of India, every minor child of that person shall there upon cease to be a citizen of India, provided that any such child may, within one year after attaining eighteen years of age, make a declaration that he wishes to resume Indian citizenship and shall thereupon again become a citizen of India.
