We would like to inform you that overstay requires that a fine of one hundred dirhams shall be paid for each day of overstay after the expiry of the residence permit.
As for cheques, a criminal case may be filed against you in order to impose a penalty of imprisonment or a fine in accordance with the text of Article 401 of the UAE Penal Code.
We recommend that you negotiate with the creditor in order not to file a criminal case against you.
Here is the text of the UAE Penal Code related to your inquiry:
Detention or a fine shall be imposed on anyone who, in bad faith, gives a draft (cheque) without a sufficient and drawable balance or who, after giving a cheque, withdraws all or part of the balance, making the balance insufficient for settlement of the cheque, or if he orders a drawee not to cash a cheque or makes or signs the cheque in a manner that prevents it from being cashed."The same penalty shall apply to anyone who endorses a cheque in favour of another or gives him a bearer draft, knowing that there is no sufficient balance to honour the cheque or that it is not drawable."It may further be noted that since the cheque amounts to Dh249,000, Law No. 1 of 2017 on Criminal Orders (Criminal Order Law), which is only implemented in Dubai, shall not be applicable owing to cheque amount exceeding Dh200,000.
