Dear client,
As per the agreement, both the LESSOR (you) and the LESSEE (tenant) are entitled to terminate the lease by giving a 2 calendar months' notice in writing. Since the tenant has given only 6 days' notice, he has violated the terms of the agreement.
You can inform the police that the tenant has violated the terms of the agreement and has not given the required notice period. You can also inform the tenant that he is liable to pay the rent for the remaining period of the notice period or rent in lieu thereof as per the agreement.
You can also deduct any damages caused by the tenant from the security deposit before refunding the balance amount. However, you should ensure that you follow the due process and provide a valid and detailed invoice of the damages caused to the tenant.
If the tenant refuses to pay the rent or comply with the agreement, you can approach a civil court for relief. It is advisable to consult a lawyer and seek legal advice on the matter.
