Filing a bounced cheque case against a debtor

Dear Sir/Madam,

Greetings for the day.

I have given AED 150,000 to a known person (who is dealing with flat lease), on his emergency situation.

He said he will pay the amount in 3 months. As a security, I took the whole amount in cheque. Apart from that, he had given 3 cheques total for AED 36000 for 3 months.

After a month he left the country and didn't come back for 6 months.

Now, its been 8 months without giving me any amount and now he is here in Dubai. So, I contacted him for the money, and he told me "I don't have money, do whatever you want".

So, I thought of going in a legal way, where I deposited all the cheques of AED 186,000 and it got bounced today.

Please guide me through the legal process, and what is the chance of getting my money back?

Now, I am seriously in a very bad situation. I am about to lose my future in the UAE because of this issue.

Please help me out.

Warm Regards,

Dinesh
