Right of way

since he has got a seperate acesss to his property he cant demand right of way through your plot

acess of way can also be given to him as demanded only in case if he pays for your area or in exchange for what you have asked

You said that you both purchased plots.  The nomenclature plot itself shows that a layout was there.  When there was layout, obviously there will be access to the road.  Even Gram Panchayat layout will have sufficient approach to the road.  This may be additional facility he is expecting. Hence, what you have raised the demand is quite reasonable.  Once you both agreed to the above said understanding you have to enter into an Memorandum of Understanding (MOU) on Rs. 100/- NJ Stamp paper, so that he or his legal heirs will not object for the understanding in future and there should not be any disputes in this regard. As this is only an understanding and no rights are being transferred, no registration in the sub registrar office is necessary for the MOU.
