Owner ship details

The property is snesistral and legally all the three sons i.e your father and two uncles are shsreholders in the propertry. The bank is rightly asking for either a gift deed  or will as you want to oust out your uncles from their legal rights. Just get setllement deed done with your uncles or you can never get the property.

A mutation entry in revenue record can neither a good title nor remove a title and it is only evidence of possession.  In case of undivided property, the possession is deemed in his capacity of the trustee, for and on behalf of all co-sharers.  Contact a local advocate for guiding you suitably.

Sir, in this case, its not ancestors property for my grandfather, as mentioned my grandfather purchased this property in his own, 

True it was not ancestral property for your grandfather but he did not make any will or gift,

just paying taxs or having tranferred land in khata does not give your father an ownership right. Mere revenue entry without any suppourting document as  will, sale or gift deed is no good title. It will be challenged any time by your cousins or uncles and would be transferred  as per rights . 

Now  the transfer of land by your grandfather to his son could have been under some need or necessasity or for any other reasons, that won't be treated as deemed will.

However if there is any order made  by Revenue officer on the application of your grandfather where he had stated that he want to transfer his owned  land to your father and signed that application that would make some sence... otherwise just recover the dues you have been paying and share the land before it will fetch litigations

But, e swattu  9/11A  also got in my father's name only,

and how can i know the details of how the property was transferred to my father's name ,, kindly let me know sir
