Me and My Borther have a land of close to 600 yards. Few years back we got division of land 50:50 thru properly registered agreement from goverment body wherein left part of land was owned by me and right part of land owned by my brother. A proper map was also submitted with registered copy of agreement diffrentiating the marked areas of lands between both of us.
Recently we decided to build one single apartment on 600 yard land and we built it in a way that Apartment has 2 blocks.
Block A having 3 flats is built on my part of land (left side) and other Block B having 3 flats is built on my brother's land (right side) but the Common area of staircase and lift section bisects both these parts. So the common apartment area of staricase, lobby and lift falls commonly on both of our parts.
We have this understanding that I can sell my block indepedently without need of approval of my brother and vice versa but still we got another agreement attested from Notary that writes clearly the Left Block flats belongs to me and Right Blocks belong to my brother and we can sell them without each others consent.
My question: In the presense of a properly registered land-ownership agreement, do we need to register this Notary Agreement for Apartment ownership and if yes how registery duty will be calculated that we will need to pay.
thanks
