Is there an expiry date to raise a civil case for bounced cheques?

Salam Alaykum.

I filed a civil case and I got a settlement where I received half the funds in cash and the rest in three cheques. At the same time, I lifted the travel ban.

Three cheques bounced to me and that person ran away from Dubai. A month later in 2012, I opened a criminal case, and the accused was sentenced in absentia to a couple of months imprisonment.

Will my case have any timeframe? When will it expire?

According to the new cheque law, can the accused clear the criminal case?

What should I do to extend the validity of my case to receive funds in the future if the accused decided to come back to Dubai?

Best regards.
