I have running a shope in a rented shop , and have lease agreement for 3 yrs for rental of Rs.8000/- per month for three years . but now the Land Owner insists us to pay 25000/- per month as rent. now he has broken the agreement, we refuse to pay 25000/- and we supposed to pay the actual rent to Court . we got stay in court and now paying the rent in court.
my question is
Who is the responsible legal person ( if there is 3 persons have share in land)to sign the Lease Deed?
Whether the Land Owner can cancel the agreement alone?
