Legal Eviction of Tenant

Hi everyone,my name is Razul Gupta and I am a follower of this site. I had inherited some property(in 1999,when I was 11 years old) from my grandfather directly, that includes 4 shops and the land behind it.Till now I was doing job in Delhi after my studies,so my father used to take care of the property. Two years ago,I quit my job and started a restaurant on a rented property in Shahjahanpur,for which I used to pay Rs 20,000/- as rent. It has been few months since I closed the restaurant because of the highway broadening and reconstruction. I am jobless now and literally doing nothing. I want to get my property vacated from all the tenants and I want to start my restaurant,on my own property.We do not have any agreement with the tenants(excluding one tenant with which my grandfather) and we do not issue any rent receipts. Rent of the shops is also very less as these were rented 12-16 years ago. These tenants have grown richer now and have political connections,they simply refuse to vacate. Also they do not pay rent on time. Two of these tenants haven't payed rent since six months. Kindly suggest how do I present my case before the court? Should I go one by one or file against all of them at once. Also, what would be the best grounds for eviction,that I should go with? Use of my property for personal use or non payment of rent.
