It is necessary to peruse terms of leave and licence to advice 

2) is there lock in period mentioned in leave and licence agreement 

3) was notice for eviction given as per terms of leave and licence agreement 

You can contest the eviction proceedings 

that you had signed agreement for 3 years and will vacate premises on expiry of leave and licence period 

If you are a tenant and ge has ground of eviction then he has right. If you are licensee then he needs to adhere to leave and license agreement of any between you and earlier owner before eviction 

In leave and license the term License means limited rights/set of rights given by one party to another to perform certain actions in or upon the immovable property, such rights are personal and non-transferable.

For tenancies that are longer than month-to-month, the landlord cannot end the tenancy without cause until the end of the term. However, the landlord does not need to give the tenant notice to move out at the end of the term unless the lease specifically requires it.

Therefore the landlord cannot evict the tenant under this arrangement before the expiration of the agreement period until and unless there is a breach of contract committed by the tenant. 

You can file a suit for permanent injunction against the landlord from forcing you to vacate or initiating steps to evict you forcibly or even by due process of law before the expiration of a valid agreement in this regard. 

The court  will not favor the landlord if he is at fault 

The terms and conditions of the agreement are to be perused to render a proper opinion to the newly added facts in your subsequent post.

Hence you may revert with the details of the agreement by which the landlord is trying to put force on you through court to get you vacated by due process of law.

It is unfortunate that your landlord has misrepresented their full responsibilities regarding their duty to notify you of the sale and their obligations as your landlord.

you should hold the landlord accountable for the misrepresentation and file a counterclaim against them with the rent control authority.

you may seek damages for the breach of contract for the period of time that you had paid for a lease and occupancy of the property.

In general, a new owner of a property would need to file an eviction suit in court if they wish to evict a tenant. However, the specifics of the situation depend on the terms of the sale agreement between the old and new owners. If the sale agreement stipulated that the old owner would retain the right to pursue any eviction suits that were already in progress, then it may be possible for the old owner to continue with the eviction suit against you.

That being said, it's important to note that you have a registered rent agreement with the old owner that is valid until June 2024. If you have paid the rent as per the terms of the agreement, then you have a legal right to occupy the property until the end of the lease term.

If you have received a summons from the rent control authority, it is important to consult with a lawyer who specializes in landlord-tenant disputes to understand your legal options and how to respond to the summons. They can also help you navigate the situation with the new owner and ensure that your rights as a tenant are protected.
