Partition deed between co-owner

Hello Sir,

I have an query about our property. My father purchased a land of 3500sqft  in a good locality in Pune, Maharashtra with our neighours long time back and both have their names in the land purchased registration[Sold person is dead so we can not correct the registration.]. even, we have a common7/12 . Now, We want to buy a morgage loan so we are facing difficulty as bank wasts a partition deed. Is there any way we can do the partition deed between us in minimum charnged?

Thanks,

Anand.
