With every marriage, the previous nomination automatically becomes NULL as per law. Therefore, if the nomination is made before this marriage, then the nomination has already become void. Under the definition of family, for PF purposes, father and mother are also included and therefore, in this case, it will be wise to share the PF amounts equally. However, for Family Pension Purposes, only wife and children are eligible and you can claim this exclusively along with child. The EDLI amount too will have to be shared just like the PF amount.
