Can a grandson claim his mother’s share in her father’s property when his mother has already died?

 After the amendment Act of 2005, according to Hindu Law by virtue of section 6, the property of Hindu male dying intestate devolves upon his heirs in Class-I category, which includes Sons, Daughters, Widows, mother etc. Hence, a son can claim a share of his mother along with other legal heirs alive in the class 1 category.
