Do we have any certificate for dakhil-kharij so that we are foolproof sure for the parental property

Hi, According to my grandfather's will the parental property belonged to my father. After his death, we claimed for the same and applied for dakhil kharij along with submitting the required documents. The officials say that the property is now transferred in my father's name and my father's name has been added in land revenue department. House tax for the same is also getting paid in name of my father. We have receipts for that too(But those house tax receipts are somewhat weird..i mean in cities we get a completely computarised slip with all the house details whereas the parental property is in village so the receipts only mention my father's name and the deposited amount only and also they are manually filled.) I suppose there is some other document too so that we can be foolproof sure that this property is now transferred to my father like some certificate or something that shows that the property has been transferred form my grandfather's name to my father's name. My question is do we have some this type of document or certificate so that we can be fully sure about it? and if it is there then how can we get it and from where? The parental property is in Kannauj UP and comes under Nagar Palika Parishad
