vacate a tenant

Under Law the land lord can not vacate a tenant from the house unless due process of law. Therefore the land lord can vacate the tenant only by following the due process of law. Either of them can not act against the terms and conditions which are entered into between them if there is any express agreement between them i.e., Rent agreement. One month prior notice with valid reason is must to vacate  the tenant. And then he need to approach the proper authority to vacate the tenant. The process should be legal and reasonable and not any illegal manner.

now the tanent is an advocate and law in favor of tenants so a long legal battle is sure.

Dear Sir,

there is no agreement with the land lord & tenant. The person who brought  & introduced him also residing in the other portion. making nusance to other tenants also. &  Land lord also  settle in  native & he's not having any other house. The building condition is very bad & we're planning to demolish & want to build new.  Even explained to the tenant he's not vacating, other tenants staying in the same house are ready to vacate.
