You issue him a legal notice to vacate the premises giving reasons as that you need the premises for your own personal use, the lease agreement has expired and you don't want to renew it and since he has defaulted in monthly rental payments.
You can state that since the current rental agreement expired on 31st January, in the absence of renewal of the agreement, he will be treated as an illegal trespasser.
If he is still not vacating then you can initiate legal action to evict him.
