Lease contract termination and and eviction of the tenant for defaulting on rent

Dear all,

I am the landlord of an apartment in Dubai and I am currently not residing in the UAE.

I have rented the place to a vacation homes company and payment was done monthly for the first three months and quarterly cheques thereafter.

They paid the first 3 months but when I tried to cash their cheque for the second-quarter payment (was due Nov 3rd) it got rejected due to insufficient funds.

The company owner asked me to help them and agree on monthly payments for 3 more months, I agreed.

The first payment should have been done before 14th Nov by wire transfer, which did not happen and since then I have been chasing him for the payment.

Finally, he provided 3 cheques for Nov, Dec and Jan, when I tried to cash the first cheque it got rejected.

I have sent them an email notice for breach of contract today. I need advice, what can I do further, how can I serve them a legal notice for non-payment and proceed to ask for eviction?

I am not in the UAE hence a POA must be made.

Thanks in advance.
