Who is legal heir of mothers property as from her parents after her death

As she got 2nd marriage without giving divorce is illegal.  So her husband may file a case in a civil court. After that you can proceed with her property.  However, engage a local experienced advocate for further guidance to get favourable orders.

1.   If the family is governed by the Hindu Law, the son, daughter and husband can have a direct inheritance claim and entitle equal share of the deceased woman property. The husband contracted a second marriage does not automatically mean that he loses his share in wife's property. The succession question and the validity of his second marriage are separate legal issues. It will be better to contact a local prudent lawyer who deals succession matter.

Wife didn't married second time it's husband who got married second time without giving first wife divorce.

Question arises can son and daughter file against father who is fraud and illegal marriage against him 

By your father's second marriage during the subsistence of the first marriage, the affected person is your mother, who is no more living hence you cannot file any complaint on this.

The property that was inherited by your mother, upon her intestate death, shall devolve on her own legal heirs who are her biological or legally adopted children and her husband (if living).

Remember that you and your siblings are also part of the total legal heirs hence you are entitled to proportionate share in the properties left behind by your mother, similarly your father is also entitled to a share in her properties as a right

What do you mean by "property as from her parents after her death"?

Is it that the property jointly belonged to the parents or that she had inherited separate  properties from them? Is it that both the parents had predeceased the mother? Please pos the complete facts in simple language.

1. If mother has died without making a bequest, her property has devolved through intestate succession under Hindu Marriage Act on her husband and all children equally notwithstanding the fact that husband performed second marriage during her lifetime without divorcing her.
2. Mother had the option of making a will or gift deed during her lifetime. 

Madhu shinde sir, I cannot understand your language.  You and your siblings with your father, have equal shares in the property of your mother, who died intestate.

The intestate propety by your mother shall devolve upon all of your siblings with father, despite the fact he got remarried with some other woman, which is irrelevant in instant case.  

Dear Querist

If mother is expired then the law of inheritance comes into picture and as per the Hindu Succession Act, 1956, you, your sister and your father shall be the first class heirs of the deceased Mother, hence he will be equally share holder of the property of your mother

and if the mother is alive then it will be better that she should execute a Will in favour of you both and espeficially mention in the Will that due to the second marriage solemnized by your father, your mother is not willing to give any share to him from her own property.
