A nominee is who receives it.
Not who owns it.
Rs 8000000 across a demat account and mutual fund folios. No will. Wife is the sole nominee. She is also one of four Class I heirs, alongside his mother and their two children.

A nomination tells the institution whose hand to put the money in. It has never told anyone whose money it is.
