No, the pension authority will not do anything to you and to your stepmother for collecting your mother's hard money earned and collected in the PF account. Only the concern was that if you were minor at the time of your father's remarriage time.

 (3)     (i)    Where a widow or widower in receipt of family pension remarries and has, at the time of remarriage, child or children from the deceased Government servant or pensioner who is or are eligible for family pension, the remarried individual shall be eligible to draw the family pension on behalf of such child or children if such individual continues to be the guardian of such child or children.

 (ii)     For the purposes of clause (i), the remarried individuals shall apply to the Head of Office in Form 14, along with a declaration that the applicant continues to be the guardian of such child or children. 

(iii)    If the remarried individual has, for any reason, ceased to be the guardian of such child or children, the family pension shall become payable to the person entitled to act as guardian of such child or children under any law for the time being in force and such person may submit a claim in Form 14 to the Head of Office for the payment of family pension.

 (4)        If the person eligible for family pension is a minor or is suffering from any disorder or disability of mind or is mentally retarded, the guardian may submit a claim in Form 14 on behalf of such person.

As per government rules till 2004, family pension could only be granted to deceased government employee’s spouse and after his or her death to the dependent son or daughter below 25 years of age. In 2004, the rule was changed to stipulate that there will be no age restriction in the case of the divorced or widowed daughter who shall be eligible for family pension even after attaining 25 years of age. An income stipulation was fixed to qualify for getting this pension. The family pension would end once the parents passed away and none of the children qualified for the pension on account of the son or daughter being married or them being above 25 years of age.

Remarriage does not disentitle your father to receive family pension of first wife 

since your step mother is nominee of all father assets she would have to pay in case any demands are made 

Dear Sir,

You are not in trouble. Your step mother will be in mother. Nothing to worry.

I am telling you the relevant pension rule. After that if you have questions  ask it. 

Remarried widower is entitled to her deceased wife's pension. In case deceased wife has any child or children, entitled to receive the pension, whom the widower shall be the guardian, the widower shall receive the pension on behalf that child or children.

It mean widower should meet out the upbringing expenditure of those children during the period of entitlement of pension. 

It has been held by the government that even in the case of remarriage of a widow, family pension can be given."

If any money is sought to be recovered it would be from legal heirs who have inherited his property 

if there is no property bequeathed by you through your father you need not need to worry. 

If your father was drawing pensions by suppression of facts then as legal representatives of father you and your step mother both are liable to pay the amount to pension department if they file the case for recovery of pension funds. 

Writ Petition in high court is the best remedy in the following circumstances
