Tenant is not ready to leave my house

Hi All, I have a house in Delhi which is been given on rent to 4 people bachelors (2 Girls & 2 Boys) in July 2017 and they claim themselves brother sisters. When i asked for ID proof and agreement they use to ignore things. Had to give them reminder for the rent all the time. Also there was some issue with the electricity connection (which i was already struggling). They people were always called us & complained about neighbors for 2 wheeler parking, electricity, water connection so on... In Nov 2017 due to such issues every now and then i had to ask them to leave my premises. Wherein i am already aware that these guys are not giving me the ID proof for agreement. Which makes me more clear that i dont want them anymore as they are not fulfilling the condition. Initially they promised me for December and then to March and now in April they have stopped taking my calls. In Feb & March there cheque got bounced which makes me impatient to continue with them without documents and money. Now i am looking for an immediate solution as they are stretching this for long & i really cant let they stay without ID proofs and agreement. NEED HELP & SUPPORT! Thanks, Nidhi
