"Section 8 of the Hindu Succession Act 1956 takes care of succession of properties of a male Hindu dying intestate (i.e. without executing any will). The said section creates a classification between the different types of legal heirs. Class I legal heirs are the near and dear ones of a person like widow, son mother daughter etc, whereas Class II consists of remoter heirs like brothers and sisters. If there are any legal heirs in class I then the property is divided equally amongst them all and the heirs in class II are excluded.
The nomination indicates the hand which is authorized to receive the amount on the
payment of which the dept. gets a valid discharge of its liability."
If you were a nominee, and no other legal heir contested the claim, company should have paid the proceeds to you.

“As per the Nomination and Labour Welfare Laws, “it is pertinent to note that while an employee has family, nomination in favour of an outsider (including Mother, Sister and Brother) is void. The rightful claimants to the sum under a policy or scheme or the share in the property as the case may, are the LEGAL HEIRS OF THE DECEASED, AND NOT THE NOMINEES."
In India, owing to the non-prevalence in the name change for nomination soon after marriage(legally), this rider option is automatically made in to effect. If the employee is unmarried, his settlement goes to his decalred nominee (father/mother/ brother etc) or any legal heir in succession by default.
In all government organizations this process is followed.
