Mr. Arup Gupta's legal advice is wrong. The Apex court and various high Courts consistently held that the Nominee's role is to facilitate the transfer of property and a simple nomination cannot over-ride the provisions of succession Act. Mr. R.R. Krishna's legal advice followed by other experts unanimously say this thing. I will quote some of the cases for your understanding.
1. Sh. Ram Chander Talwar & Anr. Vs. Devender Kumar Tawar & Ors (Delhi H.C. -decided on 20.09.2004 by Justice R.S. Sodhi (Pertains to bank nomination.)
2. Vishin N. Khanchandani & Anr. Vs. Vidya Lachman Das Khanchandani & Anr. (S.C.) - Visit Supe\uprem Court web site and in judis type the said party name and you get the full judgment.
3. Smt. Sarbati Devi Vs. Smt. Usha Devi (SC) - AIR SC 346 (Nomination in respect of the benefits of the insurance policy)
4. Ashok Chand Aggarwal Vs. Delhi Administration - 1998 VII AD (Delhi) 639 DB
5. Mr. Manmohan Kishan Malik Vs. Mr. Avtar Kishan Malik (Delhi H.C. decided on 13.10.2009 - Judge Sh. Rajiv Sahai Endlaw)
Go ahead and you will win the case.
