As per Sunni Mohameddan law, Oprhaned grandchildren are not entitle for any share in their grand parents property.
In Mullah's book, under 65A section,
He has written some thing on Residuaries, that who are all considered as residuaries.
My question whether Orphaned grandchildren comes under residuaries..or they are completely excluded from inheritance by their surving aunts or uncles...
