This book is a debutante work of the author whereby she has made an attempt to determine the validity and necessity of the presumption of legitimacy inherent in Section 112 of the Indian Evidence Act, 1872 in the light of constitutional sanction as well as the recent socio-technological advancements. Couched in simple layman terms this book seeks to avoid any excessive use of legalese or technical jargon so that it remains helpful as much for an ordinary layman as for a law student.
