How can I reach a settlement with my debtor to pay the installments?

I have a judgment against me in Dubai Courts and I don't have the money to pay. I shall pay it in 5 or 6 installments.

How to request this in court? And whom and when should I approach for the same?

I already tried with my creditor and he refused. He is proceeding with the execution formalities to block my bank accounts and RTA files.

If the bank accounts are blocked I shall be stuck with all my operation so that my receivables also will be uncollectible.
