I have been living on this land for 25 years. A small house has been present since then. Electricity Connection is also in my name. Since 3 years they have started living in southern part with there electricity connection. We have constructed more on northern side with their consent verbally. How can a electricity connection help us in the direction matter ie mine is north portion?

I got reply from a Lawyer
" An oral partition has been acknowledged. Consequently, the share of the property was acquired and has remained in your peaceful possession to date without any disturbance. To substantiate your possession and enjoyment of the property, among other supporting evidence, the water tax, property tax, electricity service connection, and utility bills in your name should suffice to affirm your title to the property, in addition to the mutation records bearing your name.

What are mutation records for a rural land?
