I want to non renewal for my tenancy contract, but...

It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that
First of all, please consider that « Consent makes the Law », and since it is by reference to the terms of the agreement concluded between both of you, that you should inform the other party in the established term and period,
So if the contract acts that you have to pay a penalty for not informing before 2 months before the expiration of the contract then please consider that it has to be done 

In the event that the intended question is otherwise, you can kindly ask us in detail and we will respond to it in the shortest time frame.
